Hello,
I looked around but do not find any example that would help me finding my error in usage. Please help me with command line syntax to use MP4box.
My MP4 file with all the correct codec but I need to do:
1. Set lang for audio track 1 and 2 to vie
2. Name the audio track 1 & 2
3. Swap the audio tracks from 1 to 2 and 2 to 1
After reading the doc, this is what tried and unsuccessfully.
MP4box.exe input.mp4 -out output.mp4 -lang 2=vie -lang 3=vie -name 2=“vocal on” -name 3=“vocal off” -swap-track-id 2:3,3:2
Thank you for helping. Thank you

Hello,
When using a recent version of mp4box with the :name=file:// command the track name will not be written to the file.
E.g. this command line on a Windows 10 x64 system:
"D:\tools\mp4box\mp4box.exe" -add "D:\sample.264#trackID=1:fps=23.976:par=1:1:name=" -add "D:\sample.aac#trackID=1:lang=jpn**:name=file://D:\sampleTRACKNAME0.txt**:delay=9" -chap "D:\sample_chptmp.txt" -tmp "D:\\TEMP" -new "D:\sample.mp4"
The txt file has only one line with 1234 in it and is a UTF8 encoded file.
I have to add it with a file:// command to be able to write UTF strings.
Using this version it fails (tried also older builds):
MP4Box - GPAC version 0.7.2-DEV-rev356-g028a7cfa-master
GPAC Copyright (c) Telecom ParisTech 2000-2012
GPAC Configuration: (static configuration file)
Features: GPAC_MEMORY_TRACKING GPAC_HAS_SSL GPAC_HAS_SPIDERMONKEY GPAC_HAS_JPEG GPAC_HAS_PNG
Error in the output is:
Unrecognized import option \sampleTRACKNAME0.txt, ignoring
It did work in the past e.g. with this version:
MP4Box - GPAC version 0.7.0-rev3-g10dc09c-master
GPAC Copyright (c) Telecom ParisTech 2000-2012
GPAC Configuration: (static configuration file)
Features: GPAC_MEMORY_TRACKING GPAC_HAS_SSL GPAC_HAS_SPIDERMONKEY GPAC_HAS_JPEG GPAC_HAS_PNG
I am not able to test inbetween.
Thank you very much for your tool and your support!

Hi Experts,
I am trying to playback the live timeline segments that are generated by a custom DASH packager. Experimenting with three different players: the Osmo4 Player, the DASH IF Reference Javascript Player, and the VLC, I found that the Osmo4 Player does not show pictures on the display window (blank window); while the other two players are playing back fine.
The Osmo4 Player does play the sample live timeline MPD (http://vm2.dashif.org/livesim-dev/segtimeline_1/testpic_2s/Manifest.mpd) from the DASH IF site though. So I am guess that Osmo4 might not like something in my MPD file, the DASH IF JS Player and VLC on the other hand might be just more forgiving.
I am attaching my MPD file here. Please let me know if you see anything obvious incorrect in my MPD. I have fed my MPD to the MPD Validator on the DASH IF site and no error is reported by the MPD Validator.
Also attached please find the dash@info logs from Osmo4 when I play my MPD file.
Any helps are truly appreciated!
Thanks,
-Donghai Ma

Hi All,
I'm having an issue where I pass the config file to MP4Client:
in past versions of GPAC, namely 0.5.x, the following code works (I know I'm passing the default GPAC config file, but this is only an example):
MP4Client -exit -cfg ~/.gpac/GPAC.cfg -lf ./bbb_x264_clientID1.txt -logs dash:network@debug http://www-itec.uni-klu.ac.at/ftp/datasets/DASHDataset2014/ElephantsDream/1sec/ElephantsDream_1s_simple_2014_05_09.mpd
But in the current version, 0.7.x, I get the following output:
Several input URLs provided ("/home/ubuntu/.gpac/GPAC.cfg", "http://www-itec.uni-klu.ac.at/ftp/datasets/DASHDataset2014/ElephantsDream/1sec/ElephantsDream_1s_simple_2014_05_09.mpd"). Check your command-line.
This seems to stem from the following change of code, in gpac/applications/mp4client/main.c:
v0.5.x
else if (!gui_mode) {
if (arg[0] != '-') {
url_arg = arg;
}
v0.7.x
if (!gui_mode) {
if (arg[0] != '-') {
if (url_arg) {
fprintf(stderr, "Several input URLs provided (\"%s\", \"%s\"). Check your command-line.\n", url_arg, arg);
return 1;
}
url_arg = arg;
}
For the life of me I can't see why "url_arg" should get the value "/home/ubuntu/.gpac/GPAC.cfg" in the preceding code in v0.7.x
Thank you for all your help

Hi,
Thanks in advance for any help. Please let me know if I should send more information privately.
**Summary**
I am trying to use MP4Box for generating a MPEG-DASH content encrypted with Widevine. As a result, I'm missing some elements in the generated manifest.
**Expected result**
Obtain a dash manifest file that includes the following elements
`<ContentProtection schemeIdUri="urn:mpeg:dash:mp4protection:2011" value="cenc" cenc:default_KID="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"/>
<ContentProtection value="Widevine" schemeIdUri="urn:uuid:edef8ba9-79d6-4ace-a3c8-27dcd51d21ed">
<cenc:pssh>PsshInfo_aaaaaaa</cenc:pssh>
</ContentProtection>`
**Actual results**
I do obtain only the following element in the manifest:
`<ContentProtection schemeIdUri="urn:mpeg:dash:mp4protection:2011" value="cenc" cenc:default_KID="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"/>`
Once I manually added the `schemeIdUri` element to the manifest xml file, I tried retrieving the license server info with a reference player (I used shaka player), and it will give me an INVALID_SERVER_CERTIFICATE error (https://shaka-player-demo.appspot.com/docs/api/shaka.util.Error.html#value:6004).
**Repro steps**
These are the steps I followed:
`MP4Box -crypt crypt.xml video.mp4 -out video_crypto.mp4`
`MP4Box -dash 600 -rap -profile onDemand -out video.mpd video_crypto.mp4#video`
This is the content of crypt.xml:
`<?xml version="1.0" encoding="UTF-8" ?>
<GPACDRM type="CENC AES-CTR">
<DRMInfo type="pssh" version="0">
<!-- See Widevine documentation for details. -->
<BS ID128="EDEF8BA979D64ACEA3C827DCD51D21ED"/><!-- Widevine identifier. -->
<BS data64="PSSHheaderData"/>
</DRMInfo>
<CrypTrack trackID="1" IsEncrypted="1" IV_size="8" first_IV="0x22ee7d4745d3a26a" saiSavedBox="senc">
<key KID="0x051bccd01e1956498601c6cbf6e7a07d" value="0xxxxxxxx"/>
</CrypTrack>
</GPACDRM>`
**Environment info**
My version of MP4Box:
`$ mp4box -version

I have used MP4Box extensively in a project I have been working over 4 months however since the requirement of project is preparing videos from frames and also other machine learning information from frames, the time has come for me to use libgpac functions inside my code. I will have to call video segmentation at particular time therefore I was wondering if there is any documentation for using the library or simply building MP4Box will allow me to do mpeg dash segmentation?
Thank you.

Hi,
We are using MP4Box to segment video and audio and generate MPEG-DASH output. We specify 10 seconds as segment duration using following commands for both audio and video. Video segments are exactly 10 seconds but audio segments are of 9.984 seconds. We know that this is expected behaviour because AAC doesn't encode audio sample by audio sample but use a time window (1024 samples for AAC) and that explains the 9.984 seconds which corresponds to 468 audio frames.
We also see that number of audio segments are higher than the number of video segments, 91 vs 90 for a 15-minute input clip.

Can mp4box use varying audio segment duration in such cases? It is possible to perform a better segmentation in this case. MP4Box can keep track of the accumulative error and can try to correct it over time.
Take below example,
In current implemenation error with respect to user configuration after:
> First segment - (10 - 9.984) = 0.016 (error of 768 samples)
> Second segment - (20 - 19.968) = 0.032 (error of 1536 samples)
> Third segment - 0.048 (error of 2308 samples)
> Fourth segment - 0.064 (error of 3072 samples)
> and so on...
If error correction is implemented, the errors can be minimized as below.
> First segment -
> Error = (10 - 9.984) = 0.016 (error of 768 samples)
> Second segment (**create a segment of 10.0053 sec instead of 9.984**)
> Error = (20 - 19.989) = 0.010 (error of 512 samples)
> Third segment (**create a segment of 10.0053 sec instead of 9.984**)
> Error = 0.0054 (error of 256 samples)
> and so on...
In this approach, we can minimize the error and it is a better segmentation approach and conforms to dash standard.
This is not really a bug but an enhancement request. This enhancement is required to avoid issues in ad-insertion use cases. When there are multiple periods in the MPD file, if audio and video segments are not in sync and drifting apart then many players detect gaps and stops playing the DASH content. There may be AV sync loss over time as well because of this.
To address these issues, this enhancement is required.
Thanks and Regards,
Anita

Greetings,
I am trying to install GPAC on Ubuntu 16.04.
I used the Debian Linux 64 version gpac_0.7.0_amd64.deb
However, when i try to play the configuration mp4 file
It gives me this error:
[SysDec] Codec GPAC BIFS Decoder AU CTS 0 Decode error Feature Not Supported
[ODM0] Decoding Error Feature Not Supported
I also tried the latest nightly build version and it also has the same problem
Would you please help me ?
Thanks in advance

Greetings,
I used kavazaar too generate a tiled hevc stream.
After that i used MP4Box split_tiles option to generate an mp4 file that has a separate track for each tile
If i want to do the opposite and get the original hevc stream.
I tried using the raw command and i got the raw hevc stream for all the tracks but i don't know how to merge them to get a single hevc stream that i can send to a single decoder or player.
I tried concatenation of all the tracks but when i played the resulting hevc stream, it gave random noise not the original video.
Another question, after dashing the mp4 file of the tile hevc stream, we have an initialization segment for each track and the m4s files for each segment and track pair. Now i want to concatenate all these files to get the mp4 file to play. What is the right arrangement to concatenate these files.
Thanks in advance

Running an encryption mp4box inserts `moov/trak/senc` box inside the init.mp4 segments(video,audio). This is not the problem 99% of the time but one of the major hbbtv brands is unable to playback drm protected video created by mp4box.
If I delete the senc(Sample Encryption Box) from all the init segments then stream is playable. All the other 99% of devices are also able to playback it as well. Also so is MSEdge(win10,playready), Firefox(win10,widevine+clearkey), Chrome(win10,widevine+clearkey), Operabeta(win10,widevine+clearkey) both streams are fine.
I was trying to study specifications whether it's against the specs to put senc inside the moov box. I tend to think it should go inside the `moof/traf` box but then the specs are not always very clear. Anyone has an opinion on this issue is this a bug in mp4box crypt segmenter?
```
MP4Box.exe -crypt gpacdrm.xml temp-v1.mp4 -out drm/temp-v1.mp4

When creating DASH OnDemand content like:
MP4Box -dash 4000 -profile onDemand -out manifest.mpd A9.mp4:id=A9 V8000.mp4:id=V8000
the duration of the first entry in the sidx box gets a value which is smaller than the actual subsegment's duration. In this example 189,440 instead of the correct value 191,488 which all other subsegments have. All subsegments have 187 samples, but the first sidx duration indicates 185 samples.

Version: gpac-0.7.2-DEV-latest-master-x64.exe
Input file: [01_000002.zip](https://github.com/gpac/gpac/files/1430196/01_000002.zip)
Command: `mp4box -dash 999999999 -profile "dashavc264:live" -bs-switching no -sample-groups-traf -out out\Manifest.mpd 01_000002.mp4`
The large segment size is there to make sure that nothing is actually segmented - I just want to split the MP4 into the "DASH components" of init segment + media segment + manifest.
Expected result: DASH presentation with 1 media segment.
Actual result: DASH presentation with 2 media segments.
`dash-strict` seems to produce same behavior.

GPAC installed via Homebrew (Mac OS X 10.11.6) - 0.7.1-revrelease
I'm not really thinking this is a bug, to be honest... but I am at a loss trying to explain what is happening. Happy to be directed elsewhere!
So, background: I was using MP4Box happily, but then I upgraded HandBrake for an unrelated reason and all of the sudden all my audio is garbled/underwater/low-bitrate sounding. Turns out it's because libav's AAC encoder replaced FDK. So I went on a wild goose chase extracting the audio from my source and then converting to AAC with FDK, and then providing _that_ instead of the audio ripped directly from the HandBrake encoded file. The workflow is exactly the same as it was before except I was extracting the AAC audio resulting from the HandBrake encode and providing that.
Since it will undoubtably help -- I uploaded the originals. The mediafire link in the template asked me for a description and I said `rfunduk-arian501-gpac`, hopefully you have them :)
Ok, so hopefully that all made sense. Here's what happens when I try to use MP4Box as I have been all along, except with the FDK'd audio:
```
MP4Box -dash 5000 -frag 5000 -rap -frag-rap -profile full -segment-name dash_seg_%s_ -min-buffer 5000 -bs-switching no -out ariane501--manifest.mpd ariane501--sd.mp4#video ariane501--hd.mp4#video ariane501.aac#audio

... many more lines like this, and finally
[MPEG-2 TS] TS Packet 214 does not start with sync marker
[DASH] File ariane501.aac not supported for dashing - skipping

```
What feature is not supported? What is a 'sync marker'? Etc. Let me know if I left out any critical info/etc!

Hello,
I'm not sure if it's the right place to ask this but i found no other way so here i am.
I usually dump the content of a mp4 using this command :
**Mp4Box.exe -dump-cover -dump-chap-ogg -raw * input_file.mp4**
Only problem i have with this is that the subtitles are extracted in a .tx3g format and i would like to get them out in .srt format ( they are originaly .srt in the input_file.mp4 ) , if using the command line :
**Mp4Box.exe -srt 3 input_file.mp4**
i can get them out after i indicate the _TrackID 3_ where the subtitle is placed.
What i would like to know is if it's possible to accomplish all this in a single step, without having to indicate the track numbers for the subtitles files, i tried to add a wildcard for the srt track like **_-srt *_** but this doesn't seems to work sadly.
The goal is to input a mp4 and dump all content, cover, chapters in ogg format, subtitles in .srt format + all audio and video tracks, without having to indicate any track numbers like the **_-raw *_** command allows it, maybe i am missing something but for now i did not found a way to do this in a single command.
Thank you very much in advance.

Is it possible to encrypt already existing nondrm init+segment files?
Current mp4box drm&packaging command use the original non-protected video.mp4 file, such as created by ffmpeg transcoding.
```
MP4Box -crypt temp-gpacdrm.xml temp-v1.mp4 -out drm/temp-v1.mp4
MP4Box -crypt temp-gpacdrm.xml temp-v2.mp4 -out drm/temp-v2.mp4
MP4Box -crypt temp-gpacdrm.xml temp-v3.mp4 -out drm/temp-v3.mp4
MP4Box -crypt temp-gpacdrm.xml temp-a1.mp4 -out drm/temp-a1.mp4
cd ./drm
MP4Box -dash 6000 -frag 6000 -mem-frags -rap -profile dashavc264:live -profile-ext urn:hbbtv:dash:profile:isoff-live:2012
-min-buffer 3000 -bs-switching no -sample-groups-traf -single-traf -subsegs-per-sidx 1
-segment-name $RepresentationID$_$Number$$Init=i$ -segment-timeline
-out manifest.mpd
temp-v1.mp4#trackID=1:id=v1:period=p0
temp-v2.mp4#trackID=1:id=v2:period=p0
temp-v3.mp4#trackID=1:id=v3:period=p0
temp-a1.mp4#trackID=1:id=a1:period=p0
```
Is it possible without any `demux-nonprotectedsegments-to-video1.mp4-ffmpeg-or-something` tricks to to create drm segments? Say I progressively receive new segment files one by one over the long period of time and must process them one by one to drm/v1_X.m4s segment files.
```
v1_i.mp4, v1_1.m4s, v1_X.m4s, ...
v2_i.mp4, v2_1.m4s, v2_X.m4s, ...
a1_i.mp4, a1_1.m4s, a1_X.m4s ...
manifest.mpd
```

I just installed GPAC (using the installer at https://download.tsi.telecom-paristech.fr/gpac/release/0.7.0/gpac-0.7.0-rev0-gbd5c9af-master-x64.exe), started "Osmo4 (with console)", and while the application was starting it deleted almost all the files in my %TEMP% directory (assigned to "C:\Temp" on my PC - Windows 7 Pro 64-bit).
It should **not** do that.
Especially without any warning that it is about to **destroy user data** - on my PC, C:\Temp contained quite a lot of stuff including files that I had created/downloaded and had yet to move elsewhere. Excuse me while I dig out an undeleter...

The MP4Box's .mp4 output from .h264 input seems to contain misplaced PPS data in the tracks.
**How to reproduce the issue**
**Test Data:**
Let's use ffmpeg to create a test .mp4 file,
_ffmpeg -f lavfi -i testsrc=duration=15.3:size=qcif:rate=10 -g 60 testsrc_1.mp4_
Then use MP4Box to extract the raw .h264 file,
_mp4box -raw 1 testsrc_1.mp4_
**Test:**
Let's use MP4Box to produce a .mp4 file from raw h264 file,
_mp4box -add testsrc_1_track1.h264 testsrc_1_track1.mp4_
Now, when if we use ISO-Viewer to go through the track NALU,
We can see that PPS bits are added to the Last Non-IDR frame of each GOP.
**Example:**
.
.
Entry{sample=SampleImpl{offset=30411{size=52}} - 52bytes [NonIDR{type:1,idc:0,size:38}, PPS{type:8,idc:3,size:6}]
Entry{sample=SampleImpl{offset=30463{size=2644}} - 2644bytes [IDR{type:5,idc:3,size:2640}]
.
.

Hi,
I use MP4Box to segment the tiled video on Ubuntu 16.04.
I encoded the video, which is in 3840x1920 resolution and 60 secs, using Kvazaar with 20x10 tiles:
```shell
$ kvazaar -i input.yuv --input-res=3840x1920 --input-fps 30.0 --tiles 20x10 --slices tiles --mv-constraint frametile -q 18 -p 30 --gop 0 -o video_20x10_qp18.hvc
```
After that, I plan to generate the segments with 1-sec length using MP4Box:
```shell
$ MP4Box -add video_20x10_qp18.hvc:split_tiles -new video_20x10_qp18.mp4
$ MP4Box -dash 1000 -profile live -out dash_video_20x10_qp18.mpd video_20x10_qp18.mp4
```
However, it always failed with an buffer overflow error message:
*** buffer overflow detected ***: MP4Box terminated

The error message will appear if the tiles are set to 10x10 as well. It will success if the tiles are set to 10x5, 9x9, 7x7, 5x5, 3x3. Therefore, I was wondering whether there is a limit for the number of tiles in the encoded video for MP4Box? If yes, how to modify it to support more number of tiles?
Many thanks!

Using other tools, generate a 33 hours audio only long file (maybe using AAC codec).
Then using Mp4Box, to remux it.
The orignal will have a STTS table like this (one entry with 5235839 samples at 1024 duration)
```
<stts>
<Address Value="0x0000000056F53BBA"/>
<HeaderSize Value="8"/>
<DataSize Value="24"/>
<Size Value="32"/>
<ParserReadBytes Value="32"/>
<Version Value="0"/>
<Flags Value="0x00000000"/>
<EntryCount Value="2"/>
<Entry Index="0">
<SampleCount Value="5235839"/>
<SampleDelta Value="1024"/>
</Entry>
<Entry Index="1">
<SampleCount Value="1"/>
<SampleDelta Value="498"/>
</Entry>
</stts>
```
After using MP4Box, you will get new entries, with one sampleDelta of 0
```
<stts>
<Address Value="0x0000000000000256"/>
<HeaderSize Value="8"/>
<DataSize Value="32"/>
<Size Value="40"/>
<ParserReadBytes Value="40"/>
<Version Value="0"/>
<Flags Value="0x00000000"/>
<EntryCount Value="3"/>
<Entry Index="0">
<SampleCount Value="1041535"/>
<SampleDelta Value="1024"/>
</Entry>
<Entry Index="1">
<SampleCount Value="1"/>
<SampleDelta Value="0"/>
</Entry>
<Entry Index="2">
<SampleCount Value="4194304"/>
<SampleDelta Value="1024"/>
</Entry>
</stts>
```
The problem is that in the code, you are multiplying u32 * u32 to get some DTS
In this case, you will get 5235839 * 1024 = 1066531840 (instead of 5361499136)
The follow patch seems to fix the problem for me:

Issue Descriptions:
I am using the Osmo4 player on my MacBook Pro to play back a DASH mpd file in chunk LowLatency mode. After running for a while (varied from a few minutes to 1-2 hours), the player exits due to a segmentation fault. When this happens, the player will always exits with the same error when I try to re-start it, until I reboot my laptop.
Here are my command line options:
$ /Applications/Osmo4.app/Contents/MacOS/Osmo4 http://10.91.112.125:8888/llabr/dcmcap/dash.mpd -opt Network:BufferLength=800 -opt DASH:LowLatency=chunk -opt DASH:UseServerUTC=no

I have a problem when importing a video stream encoded with h264_nvenc in h264 raw format. My system configuration:
- Windows 10 Pro 64 Bit (Version 1703)
- MP4Box version 0.7.2-DEV rev283
- All commands are executed via the cli
Please find video examples at the following urls.
Original video:
https://test.team-andro.eu/video/examples/ace2011.mov
540p encode h264 raw:
https://test.team-andro.eu/video/examples/ace2011_540p.264
The video encode has a frame rate of 29.970 with a key frame interval of 150 frames. This means: The first frame is a key frame, the 151st frame is a key frame and so on. The reason for that is to get a dash interval of 5,005 seconds.
After creating the h264 raw stream I import it with the help of MP4Box. Cli command:
MP4Box -add ace2011_540p.264#video:fps=29.97 -new ace2011_540p.mp4
This has always worked without any problems. The last version of MP4Box I've been using was 0.7.2-DEV rev34 from May 2017. Now I've updated MP4Box to 0.7.2-DEV rev283 and the behaviour is different. Please see the following examples.
File after import with 0.7.2-DEV rev34
https://test.team-andro.eu/video/examples/ace2011_540p-rev34.mp4
File after import with 0.7.2-DEV rev283
https://test.team-andro.eu/video/examples/ace2011_540p-rev283.mp4
If you analyze those videos with the help of ffprobe, you will see that the key frame at the beginning is missing in the version created with 0.7.2-DEV rev283. ffprobe commands to create text files listing all frames:
ffprobe -i ace2011_540p-rev34.mp4 -show_frames > rev34.txt
ffprobe -i ace2011_540p-rev283.mp4 -show_frames > rev283.txt
Please see my examples at:
https://test.team-andro.eu/video/examples/rev34.txt
https://test.team-andro.eu/video/examples/rev283.txt
The problem becomes obvious when a dash stream is created based on such imports (with 0.7.2-DEV rev283). The missing key frame at the beginning leads to a big gap and the video won't play. Please see the following examples:
Dash stream created with 0.7.2-DEV rev34
https://shaka-player-demo.appspot.com/demo/#asset=https://test.team-andro.eu/video/ace2011-rev34/mp4_1.mpd;lang=en-US
-> plays fine
Dash stream created with 0.7.2-DEV rev283
https://shaka-player-demo.appspot.com/demo/#asset=https://test.team-andro.eu/video/ace2011-rev283/mp4_1.mpd;lang=en-US
-> doesn't start
The problem doesn't occur in conjunction with libx264 encodes.

In some types of video streams, you can have the aspect ratio change in the middle of the stream (e.g. a TV channel that interleaves 4:3 and 16:9 movies). I would expect any aspect ratio change to result in a new period in generated DASH.
I do not currently have useful test data in this form so I cannot simply try it out but I thought I should just ask - is this supported? Does mp4box understand changes like this and handle them? Or does it just use whatever metadata it detects at the start of the input stream and ignore changes?

I wish to append new segments to a dynamic MPD generated by successive calls to mp4box, using dash-ctx mode. However, I find that each invocation of mp4box results in a new period being added instead. This is not desirable - I simply wish to add more data to the existing period.
Is this a supported scenario and, if so, how am I meant to invoke mp4box in order to achieve appending of data?
I tried manually specifying the period name but that appeared to result in overwritten segments instead of appended.
Example input files (audio only for small download size) to be appended to make one large segment:

This isn't a bug - just something that I'd like to try out and get an opinion if it is a good way to go about things.
I've been using MP4Box to generate DASH content from video files and hosting it on Google Cloud Storage. Till now, access to streaming these files has been restricted to a trusted network, so I could keep the links (MPD, m4s segments etc.) on my storage bucket public. However, I now have a requirement to open streaming access on a public network. As such, I wanted to experiment with making these links private and editing the MPD programmatically to contain secure signed URLs for each segment like so -
`<SegmentURL media="<signed url to an m4s file>"/>`
Will manually editing thusly generate a valid MPD? Is this a good approach to ensure secure links to the video files for streaming? Or should I instead figure out an approach using encryption / DRM supported by MP$Box?

Apparently, MP4Box does not support HEIF/HEIC as generated by iOS 11 devices. Here are samples I took with my iPhone 7+ myself, useful for tests and debug.
https://avi.alkalay.net/clipboard/HEIF-iOS-11.zip
Zip file contains videos, regular photos, photos with depth and photo bursts.
I'm particularly interested in MP4Box support for iOS 11 HEIF tags and metadata.
This is what I get with GPAC 0.6.1 on Fedora Linux:
```
$ MP4Box -info IMG_4453.HEIC
[iso file] Read Box "infe" failed (Invalid IsoMedia File)
[iso file] Read Box "iinf" failed (Invalid IsoMedia File)
[iso file] Read Box "meta" failed (Invalid IsoMedia File)
Error opening file IMG_4453.HEIC: Invalid IsoMedia File
```
And this is 0.7.1:
```
$ MP4Box -info IMG_4449.HEIC

Hi,
We want to package multiple MP4 files (of 10 seconds each) into DASH content such that the resolution may vary across these files. We are indicating the discontinuity of resolution by inserting a new period in MPD. Further, we are using -dash-ctx option and multiple MP4Box commands to achieve this. Please find the 4 commands below that we used to package 4 different MP4 files of 10 seconds each.
```
Command1: MP4Box -quiet -dash-strict 10000 -rap -dash-scale 1000 -tfdt 0 -moof-sn 0 -subsegs-per-sidx -1 -mpd-title "dash-chunked-transcode" -dash-ctx ctx.txt -mpd-info-url abc.com -segment-name test_0 input_480_270_1159kbps.mp4:period=0:id=0 -out manifest.mpd
Command2: MP4Box -quiet -dash-strict 10000 -rap -dash-scale 1000 -tfdt 10000 -subsegs-per-sidx -1 -mpd-title "dash-chunked-transcode" -dash-ctx ctx.txt -mpd-info-url abc.com -segment-name test_0 input_480_270_1133kbps.mp4:period=0:id=0 -out manifest.mpd
Command3: MP4Box -quiet -dash-strict 10000 -rap -dash-scale 1000 -tfdt 20000 -moof-sn 2 -subsegs-per-sidx -1 -mpd-title "dash-chunked-transcode" -dash-ctx ctx.txt -mpd-info-url abc.com -segment-name test_1 input_768_432_785kbps.mp4:period=1:id=0 -out manifest.mpd
Command4: MP4Box -quiet -dash-strict 10000 -rap -dash-scale 1000 -tfdt 30000 -subsegs-per-sidx -1 -mpd-title "dash-chunked-transcode" -dash-ctx ctx.txt -mpd-info-url abc.com -segment-name test_1 input_768_432_783kbps.mp4:period=1:id=0 -out manifest.mpd
```
Please note the manifest file at the end of each command with GPAC version 0.7.1:
Same is present at [Observations_GPACv0.7.1.zip](https://github.com/gpac/gpac/files/1292113/Observations_GPACv0.7.1.zip)
Note the SegmentList within manifest file post Command3 (complete manifest file is present in the directory Command3_Segment11).
```
<Period id="0" duration="PT0H0M20.000S">
<SegmentList timescale="12800" duration="128000">
<Initialization sourceURL="test_0init.mp4"/>
<SegmentURL media="test_01.m4s"/>
<SegmentURL media="test_02.m4s"/>
</SegmentList>
</Period>
<Period id="1" duration="PT0H0M10.000S">
<SegmentList timescale="12800" duration="128000">
<Initialization sourceURL="test_1init.mp4"/>
<SegmentURL media="test_01.m4s"/>
<SegmentURL media="test_02.m4s"/>
<SegmentURL media="test_11.m4s"/>
</SegmentList>
</Period>
```
My question is that, why does period 1 has 3 segments? I expected it to have only test_11.m4s. Looks like GPAC maintains this list of segment internally and doesn't clear when new period starts.
Additional information:
1. How I obtained GPAC:
Downloaded using the command: wget https://github.com/gpac/gpac/archive/v0.7.1.tar.gz
Built the same post that.
2. Operating System: CentOS Linux release 7.1 64 bit
3. Application used: MP4Box
4. GPAC version:
MP4Box - GPAC version 0.7.1-revrelease
Further, I tried executing the four commands with the latest nightly build of GPAC. (GPAC version 0.7.2-DEV-revUNKNOWN_REV). Behaviour with this version is little different.
Note the SegmentList within manifest file post Command3 (complete manifest file is present in the directory Command3_Segment11 inside
[Observations_GPACv0.7.2-DEV.zip](https://github.com/gpac/gpac/files/1292247/Observations_GPACv0.7.2-DEV.zip)
).
```
<Period id="0" duration="PT0H0M10.000S">
<SegmentList timescale="12800" duration="128000">
<Initialization sourceURL="test_0init.mp4"/>
<SegmentURL media="test_01.m4s"/>
<SegmentURL media="test_01.m4s"/>
</SegmentList>
</Period>
<Period id="1" start="PT0H0M10.000S" duration="PT0H0M10.000S">
<SegmentList timescale="12800" duration="128000">
<Initialization sourceURL="test_1init.mp4"/>
<SegmentURL media="test_01.m4s"/>
<SegmentURL media="test_11.m4s"/>
</AdaptationSet>
</Period>
```
I expected it to have only test_11.m4s in period 1, but it has both test_01.m4s and test_11.m4s. Which looks wrong.
Regards,
Anita

I am working on rate adaptation for SRD tiles. I noticed that the MP4Client is not playing tiles for HEVC based SRD video if it is not in local file mode, even if the files are located on the localhost. To explore further, I played a video from Apache server and controlled the bandwidth through traffic shaper in a single client -server architecture with no other cross traffic. The bandwidth was set to a much higher value than the cumulative highest bitrate. It was very strange that the download rate logged on line 5565 of dash_client.c shows some random values that vary too much from the value set by traffic shaper. Could this be the reason that tiles are not getting played at highest bitrate even if bandwidth is enough?

Hi there,
I see on the GPAC post that there is an easy way to create HEIF files using mp4box... Apologies if this is clearly stated somewhere, but is there a way to get jpeg's from .heic files using mp4box? Any documentation/references would be greatly appreciated.
Thanks!

I have been following GPAC's demo on hybrid broadcast broadband of UHD SHVC video streams:
http://download.tsi.telecom-paristech.fr/gpac/demos_hybrid/
In the demo, the base layer is broadcasted in TS format using multicast UDP, while the enhancement layer is sent in a DASH session. On the client side, MP4Client is able to play the video with both layers (which are sent separately) in sync. My question is how does MP4Client take 2 separate streams and play them out in sync? which part of the client source code is responsible for that?

Hello everyone,
I am trying to see a video encoded in hevc:
> MP4Box -v -add Cactus_1920x1080_50_qp32.bin:FMT=HEVC -fps 50 -new output.mp4
> MP4Client output.mp4
The window appears but with no video, black and in the console appears the next problem:
[NVDec] failed to create cuvid decoder CUDA_ERROR_NO_DEVICE
I have a graphic card that uses the hardware to decode hevc but it does not work.
Any solution?
Thanks, Ignacio.

(I'm putting this here instead of writing a long commit message)
When running configure with` --static-modules` or `--enable-static-bin`, the `static.mak` puts all necessary include dirs (`-I`) on the gcc command line.
If OpenSVCDec is detected present, it will add `-Iextra_lib/include` to the command line : https://github.com/gpac/gpac/blob/master/configure#L1072
So now the headers in `extra_lib/include` will all have higher priority than the system ones (see: https://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html#Directory-Options).
In particular, in `utils/downloader.c`, when we `#include <openssl/ssl.h>`, it's the version in `extra_lib/include` that will be included. But this version seem to only be for windows (https://github.com/gpac/gpac/blob/master/extra_lib/include/openssl/opensslconf.h#L5).
The only way for system headers to have a higher priority than local header is to use `-idirafter` instead of `-I`.

Tried using GPAC 0.7.2 32-bit build for Windows. Looking to add a properly populated btrt atom to an encoded file.
Encoded a file with FFmpeg using x264, ran through `MP4Box -isma -out 47.mp4`
Output attached. [out_47.zip](https://github.com/gpac/gpac/files/1209849/out_47.zip)
Please advise how to properly create BTRT atom in MP4 and populate its values appropriately. Thank you!

How should I install GPAC from command line in windows?
I need to automate my machine configuration and installing GPAC programatically, so I expect to install it from command line.
Expected: call gpac.exe /quiet and it get installed
Actual: gpac is prompting a graphical interface to install
Platform: Windows 10 and Server 64bit
Build used: gpac-0.7.0-rev0-gbd5c9af-master-x64.exe
Also, an msi would be much easier to install in Windows machines, which already has option to install from command line.

Hi,
I'm trying to extract audio stream from some MP4 files located in a same folder, so I tried the command
`FOR /R %G IN (*.mp4) DO "c:\program files (x86)\GPAC\mp4box" - raw 2 %G`
The command tries the extraction for each file, but always with an error
`c:\program files (x86)\GPAC\mp4box" -raw 2 "working_dir\file.mp4
Error - 2 input names specified, please check usage`
However, if I run the same command but written by me, it works, and I don't understand why
[EDIT] I use gpac-0.7.2-DEV-rev223-g06e9447-master-win32 on an updated W10

Hello to all, i pass the past two weeks to setup DashCast for live media purpose.
The purpose is to obtain a live media streaming of a video playlist and loop it when is finish.
I used the GPAC Ubuntu 14.04 compilation guide on GPAC site.
Below the sequence of commands to prepare the test:
```

```
I also download chrome for media decoders.
Now for my first test i use localhost, i put the source video, dash.all.min.js and the html page inside /var/www/html
I run
sudo DashCast -av t4.mp4 -live-media
I'm still unable to play audio and video toghether due to video and audio encoder errors below the terminal result:

I am trying to split into chunks a long running h264 video, but the last chunk (sometimes many chunks) is always around 700 bytes and therefore it is not a valid mp4 video file.
Is there a way to avoid it?
I tried -split and split-size but I got the same result.
Below the output of the command:
```

Does GPAC support playing 360 degree video side by side ?, So that we can watch videos directly with HMD (Head Mounted Display).
If GPAC does not support then can you give me some pointers on how to extend/modify the GPAC to play videos side by side?.

The DASH live simulator has been modified to fix a number of different issues:
- non-aligned audio and video durations would cause desync after a few loops
- forcing duration of media input was not properly working
- drift would occur between the media timeline (ie tfdt) and the MPD segment startTime when using templates without segment timeline, causing potential 404 and other weird behaviours in seek requests
We also added the possibility to force a new period rather than looping the source content (using -no-loop switch)
This should fix quite a few issues on the live simulator, but don't hesitate to reopen this issue if needed.

I recently started using mp4box, after it was recommended to me on the ffmpeg user email list.to extract the raw video from an AVI video and then use ffmpeg to extract the audio and combine it with the raw video to get the scaled mp4 video I need. Alas, I am having problems with mp4box.
I first downloaded the windows version in 64 bit format from this site:
https://gpac.wp.imt.fr/downloads/
but whenever I tried to run any command, it crashes with this message from Windows:
**mp4box has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.**
So I downloaded the 32 bit version and that worked fine for me while I was processing small files. But yesterday, I tried to extract raw video from a 700,000 kb file and the 32 bit version of mp4box crashed with the same message from Windows (see above).
So I downloaded the latest versions (32 bit and 64 bit for Windows) from the daily build site (https://gpac.wp.imt.fr/downloads/gpac-nightly-builds/) and tried again, but got the same results. The 64 bit version doesn't work at all and the 32 bit version only works on small files. I tried this with revision 195, the first one in the list of files available for download on the nightly builds page and with revision 200, hoping that the higher revision number may indicate that this is the latest revision, not the first one in the list.
I tried starting the debugger when I got the error message, but since I don't have the source code I don't get much info. The debugger says the problem was caused by an unhandled exception, but that's all it can tell without source code.
The system Application log also shows and error but gain, there is no useful information other than the application (mp4box) and the time of the error. The log can't record what the application does not pass on.
BTW, the mp4box command I am using is:
mp4box -aviraw audio hd.avi
The video is NOT interlaced, although it is supposed to be, which is why I need to extract the raw video before I can scale it using ffmpeg.
I tried attaching my test file but I was told that you don't support that file type. So if you want to get my test file called hd.avi, you can get it here:
https://www.dropbox.com/sh/61kb841ayiwj28l/AAC46KAoNSCiI85LwFjM9tpba?dl=0
Just remember the 64 bit version crashed even on the small test video, while the 32 bit version runs fine on the small file. I can provide a larger file if you need one, but I don't have the space on my dropbox page. I would need ftp access or something like that to give you a copy of one of my larger videos.
I am running Windows 10 Pro 64 bit version, with 16 GB of ram and an Intel i7 CPU.
I really need to solve this ASAP. So if there is something I can do to get either version to work, let me know. And if I did not include some detail you need, just contact me and I will try to provide the info you need.
Thanks

If I type the following command:
`"C:\Program Files\GPAC\mp4box.exe" -par 1=1:1 "E:\NAS\video\Vidéos de famille\2010\Alex 2010\HDV_0091.MP4"`
in a command prompt (cmd.exe) under Windows 10, the temp file "out_HDV_0091.MP4" is correclty created, but the command cannot finish because there is an error when the soft try to remove the old file:
```
Saving E:\NAS\video\Vid├®os de famille\2010\Alex 2010\HDV_0091.MP4: 0.500 secs Interleaving
Error removing file E:\NAS\video\Vid├®os de famille\2010\Alex 2010\HDV_0091.MP4
Error: I/O Error
```
I get the same error with Powershell:
```
Saving E:\NAS\video\Vidéos de famille\2010\Alex 2010\HDV_0091.MP4: 0.500 secs Interleaving
Error removing file E:\NAS\video\Vidéos de famille\2010\Alex 2010\HDV_0091.MP4
Error: I/O Error
```
The issue seems to be related with the space and the 'é' char contained in path. Perhaps the remove function called to drop the file doesn't support Unicode path.
As workaround, I use the "-out" parameter to not use the in-place rewrite feature. I manually delete old video files after processing.

Might be related to #183 - reason may be same or different.
Samples available at: http://www.mediafire.com/?9lz533ddlj111
According to a report in a German video forum, using MP4Box to extract raw streams from an MP4 video with 7.1 channel AAC results in a raw AAC audio file which is detected as only 5.0 channel by MediaInfo and ffmpeg (ffplay), and MPC-HC (using LAV Filters natively as decoders, which are based on ffmpeg/libav*) gets stuck when playing an MKV multiplexed with this audio using mkvtoolnix; but VLC can play the remux.
To test this issue, I downloaded some [Dolby TrueHD trailers](https://thedigitaltheater.com/index.php/dolby-trailers/), extracted the 7.1 THD audio with conversion to FLAC using eac3to v3.31, converted the FLAC audio to LC-AAC in MeGUI using QAAC x64 v2.64 (CoreAudioToolbox 7.10.9.0 from iTunes installer), then extracted the AAC to raw/ADTS files using MP4Box from gpac-0.7.2-DEV-rev206-gf32d687-master-x64 (`mp4box -raw * ~.m4a`).
The sample archives in the MediaFire folder linked above contain all intermediate files and verbose reports generated by MediaInfo 0.7.97 (CLI, 2017-06-29) and ffprobe (N-86720-gf1baafac71, 2017-07-06).

So probably? due to the patch for #873, supplying nothing to the ":name" modifier for 'add' results in this error:
`[Importer] Unknown input file type for "new_chapters.xml:name=:"
Error importing new_chapters.xml:name=:chap: Requested URL is not valid or cannot be found`
but ONLY when
a) importing a xml/ttxt chapters track
b) putting the name parameter ahead of the chaps parameter.
For example,
`mp4box -add "video.mp4#trackID=1" -add "new_chapters.xml:name=:chap" -new "video_new.mp4"`
will result in the above error, but
`mp4box -add "video.mp4#trackID=1" -add "new_chapters.xml:chap:name=" -new "video_new.mp4"`
will work fine.
All of this is happening with the latest nightly x86 build, gpac-0.7.2-DEV-rev200-g9566a94-master, on Windows 10 x64.
(FWIW, the purpose of supplying a blank name parameter is to avoid having the default trackname mp4box generates being written.)

Hi, for the first test i would try to send only audio, an wav file into dashcast live.media
I use the code below

Hi there, I'm trying to create a live with dashcast, I want to understand if the dashcast process that create output folder should take place on the web server or whether I can sync the output on my computer with an ftp on a webserver. This cause i don't have a webserver and i want to use an hosting service for the media distribution
Thanks a lot

I am trying to create a motion constrained segmented video for HEVC Tile-based adaptation.
I encoded them into 4 QP using kvazaar.
kvazaar --input YachtRide_1920x1080_120fps_420_8bit_YUV.yuv --tiles 3x3 --slices tiles --mv-constraint frametilemargin --qp 25 --output out1.hevc
kvazaar --input YachtRide_1920x1080_120fps_420_8bit_YUV.yuv --tiles 3x3 --slices tiles --mv-constraint frametilemargin --qp 30 --output out2.hevc
kvazaar --input YachtRide_1920x1080_120fps_420_8bit_YUV.yuv --tiles 3x3 --slices tiles --mv-constraint frametilemargin --qp 35 --output out3.hevc
kvazaar --input YachtRide_1920x1080_120fps_420_8bit_YUV.yuv --tiles 3x3 --slices tiles --mv-constraint frametilemargin --qp 40 --output out4.hevc
Then I used MP4BOX for packaging.
MP4Box -add out1.hevc:split_tiles -new video_tiled1.mp4
MP4Box -add out2.hevc:split_tiles -new video_tiled2.mp4
MP4Box -add out3.hevc:split_tiles -new video_tiled3.mp4
MP4Box -add out4.hevc:split_tiles -new video_tiled4.mp4
Finally DASHing them as :
MP4Box -dash 1000 -profile live -out t.mpd video_tiled1.mp4 video_tiled2.mp4 video_tiled3.mp4 video_tiled4.mp4
The output thus generated is showing only one quality and is not able to switch to other quality while being played through MP4Client.
I verified the configuration of MP4Client by the sample given at http://download.tsi.telecom-paristech.fr/gpac/SRD/srd_hevc/multi_rate_p60/hevc_srd.mpd, where the player is showing other quality as well and able to change the quality level through GUI. Am I DASHing the video in wrong way?

Consider an mp4 video that has a gpac ttxt menu track in it, plus an arbitrary amount of other tracks (audio, subtitle, whatever). Let's say one were to create a new mp4 by importing the video track only, and wanted to replace the current gpac ttxt menu with a different gpac ttxt menu.
For example, video.mp4 has video track 1, audio tracks 2, and 3, subtitle track 4, and ttxt chapter track 5, and I want to create video_new.mp4 with video track 1, a new audio track from a separate file, and a new chapter track, also from a separate file:
`mp4box -add "video.mp4#trackID=1" -add "audio.mp4#trackID=1" -add "new_chapters.xml:name=:chap" -new "video_new.mp4"`
**This results in a video that indeed has the new chapter track.** However, we are warned about the reference to the now-orphaned original menu:
`Warning: track ID 1 has references to a track not imported`
and the presence of the reference to the old chapter track remains. In other words, if one runs MediaInfo on video_new.mp4, the 'Menus' line of the video track will list two track IDs: the ID of the original track in video.mp4 - in this example, 5 - and the ID of the new chapter track - here, 3. In other words,
`<Menus>5,3</Menus>`.
**On playback, phantom chapter track 5 will preempt real chapter track 3. Real chapter track 3 will never be parsed or acknowledged by the player in question. Practically, it's like it isn't there at all.**
If, by chance, the trackID of the chapters track added to the new video matches the trackID of the chapters track in the original video, then there is no problem - there is no duplicate track entry in the Menus line of the video track in MediaInfo, and everything works fine. Obviously that isn't an acceptable workaround, though.
Additionally: in the example above, I specified a new chapters file. Importing the old chapters track from the old file, like so:
`mp4box -add "video.mp4#trackID=1" -add "video.mp4#trackID=3" -add "video.mp4#trackID=5:name=:chap" -new "video_new.mp4"`
does result in a warning about not importing a referenced track, but does NOT result in the phantom menu issue, because **the track IDs of the original mp4 are retained!** This is appears to be odd behavior - while on the plus side, other track information, like track language and track name, is also retained, having trackIDs skip around instead of simply being reassigned from scratch is odd. And it doesn't stop there. Let's say one decided to import the video track and one of the audio tracks from the original file, but supply a new ttxt chapters file:
`mp4box -add "video.mp4#trackID=1" -add "video.mp4#trackID=3" -add "new_chapters.xml:name=:chap" -new "video_new.mp4"`
In this case, the audio file imported **retains its track ID of 3**, and the chapters file is assigned a track ID of 4 - the next whole number. This results in the same issue - two menus being referenced, one of which isn't in the file, but preempts the second, extant menu from being recognized or loaded. As might be guessed, importing the audio track with track ID 4:
`mp4box -add "video.mp4#trackID=1" -add "video.mp4#trackID=4" -add "new_chapters.xml:name=:chap" -new "video_new.mp4"`
works, since the track ID of the the new chapters file would be assigned 5 - the same as in the original file.
**This only straightforward, complete workaround to this problem** is first manually exporting the video track from the original mp4, and then importing it, instead of importing the original mp4 directly and specifying the trackID of the video in the import parameters. While this works, it is also an extra, inelegant, time-consuming step.
**Alternatively, one can also, either after the fact or in the original creation of the new file**, change the trackID of the new chapters file to match that of the trackID of the chapters in the original file. For example, in the case of a file with chapters that have a trackID of 4, but which originated from another file with chapters that had a trackID of 5:
`mp4box video_new.mp4 -set-track-id 4:5`
Or, equivalently, during the original creation of video_new.mp4 (again, using an audio track other than the one with the trackID of 4):
`mp4box -add "video.mp4#trackID=1" -add "video.mp4#trackID=3" -add "new_chapters.xml:name=:chap" -set-track-id 4:5 -new "video_new.mp4"`
In these cases, in MediaInfo, there are still two entries in the Menus line of the video track's information - it changes from `<Menus>5,4</Menus>` to `<Menus>5,5</Menus>` - but the chapters do get parsed (at least with the playback software I was using). If one decides to change the track ID again - let's say to 2 - the chapters will still work, however, the Menus entry for the video track reads `<Menus>2,5</Menus>`, rather than `<Menus>5,2</Menus>`. The lingering presence of an extra track reference seems undesirable: I have only tested these videos with one piece of playback software, after all, and even if I haven't, this just seems 'wrong'.
**In conclusion**, if possible, a flag should be added that strips the original file of useless/obsolete track references upon importation. Or, even better, the default behavior should be the stripping of such track references, and a flag should be added that would disable such stripping. (**Aside from that,** it might make good sense to renumber tracks upon import, rather than retaining original trackIDs from a now obsolete context. But, this is a separate issue, whose consequences are not always obvious. The obsolete track reference issue is more concretely negative.)
All this was observed with the latest nightly on Windows 10 x64. I have only been able to test whether chapters work in MPC-HC 1.7.11 x86 as I do not have an iDevice handy at the moment, but it is clear that the reference to the no-longer-existing chapters file is undesirable regardless.
**ED:** All of this was actually observed with GPAC version 0.7.0-rev3-g10dc09c-master (I had installed the newest nightly to a different location, but forgot to change the PATH variable in Windows to reflect this). But when using GPAC version 0.7.2-DEV-rev192-gd1ee384-master, the issues are even stranger: instead of 2 Menus entries, there are **3**, so, it seems like things haven't improved (or potentially, have gotten worse...)
**ED2:** It appears that if one simply does `mp4box -add "video.mp4" -new "video_new.mp4"` on a video file containing a ttxt menu, a) the ttxt menu is still imported, b) it is assigned a trackID of two, c) none of the other tracks are imported, d) the `Warning: track ID 1 has references to a track not imported` error still occurs, and e) the Menus entry of the video track in MediaInfo still contains two references, first to the original track ID, then to track 2.

When importing a track, when using an import option which itself could take a colon in its parameters, that option is not properly parsed: everything after the colon is treated as its own import option, and is flagged as invalid.
For example, consider this command:
`mp4box -add "video.mp4#trackID=1:fps=59.960:par=10:11" -new "video_new.mp4"`
This results in the error,
`Unrecognized import option 11, ignoring`
Or this command:
`mp4box -add "video.mp4#trackID=1:fps=59.960:name=file://trackname.txt" -new "video_new.mp4"`
This results in the error,
`Unrecognized import option //trackname.txt, ignoring`
In each of these cases, there is an alternative - using the separate "-par" or "-name" options after the initial -add. But both the help screen in mp4box and the official documents still list the use of :par and :name as valid import options (in other words, as valid parameters to modify a string being fed to the '-add' parameter).
If this functionality was intentionally removed, and end users wanting to specify a pixel aspect ratio or a trackname contained in a text file should use the general -par and -name options, then the help text and documentation should be changed to reflect this. Otherwise, whatever change was made that broke these options should be reverted.
This issue occurs with the latest nightly on Windows 10 x64.
ED: All of this was actually observed with GPAC version 0.7.0-rev3-g10dc09c-master (I had installed the newest nightly to a different location, but forgot to change the PATH variable in Windows to reflect this). But, this issue persists in an identical manner on GPAC version 0.7.2-DEV-rev192-gd1ee384-master.

I tried to build gpac_extra_libs on Windows 10, using VS2015 Community. For libfaad, the function `lrintf` is defined in two places:
1. Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt\math.h
2. gpac_extra_libs\faad2\libfaad\common.h
To get it to compile, I commented the second one.

The batch file CopyLibs2Public.bat in gpac_extra_libs that you get by calling

is old and different than the one stored here:

Here you can see [the difference](https://www.diffchecker.com/Tq8PemaZ).
Also, in both versions the link https://ftp.mozilla.org/pub/mozilla.org/mozilla.org/xulrunner/releases/7.0.1/sdk/xulrunner-7.0.1.en-US.win32.sdk.zip
is broken and should be replaced by

Hello guys,
I have encoded different videos using FFmpeg. Then I wanted to segment them using DashCast, however, I realised that I have to introduce a configuration file.
If I do that, this would mean the encoded files from FFmpeg will be encoded again!!
Is there any way I can disable using -conf option and just make DashCast only doing segmentations for the existing videos. The encoded videos are .mp4
Thanks

I have read this topic and various gpac blogs but don't have the clear answer.
https://github.com/gpac/gpac/issues/521
**I have a 3min(180sec) videofile** dashed to 6sec segment files. **I need later run separate processes** to split subtitle-langx-ttml.xml files. **Subtitles don't span over the entire video duration,** some files may have just 00:10-00:40(30sec) of text elements.
What is the best way to serve ttml.xml content so that playback does not interrupt at 00:40 for 404NotFound subtitle.m4s errors?
1. Use `:dur=180` attribute for subtitle.mp4 input file, do not place an empty placeholder P text element to the end of xml file? Last text element is cloned on remaining segment files however not rendered anymore.
2. Use `:dur=180` attribute for subtitle.mp4 input file, add an empty 1sec begin=00:41/end=00:42 placeholder P text element to the end of xml file? Remaining segment files have an empty text element however not rendered.
3. Modify sub-ttml.xml file to have an empty P text element spanned over begin=00:41/end=03:00 duration? Does not sound a good solution.
4. Something else available in mp4box tool or best practices being used?
```
mp4box -add subeng.xml:ext=ttml -new temp-subtitles.mp4
mp4box -dash 12000 -mem-frags -profile dashavc264:live
-bs-switching no -sample-groups-traf -single-traf -subsegs-per-sidx 1
-segment-name "$RepresentationID$/sub_$Number$$Init=i$"
-out temp-subtitles.mpd

Hello,
I have two MP4 videos encoded using SHVC reference software SHM12.3; one with one layer only (out.mp4) and the second with 2 layers (out2l.mp4).
MP4Client is able to play the first version, but unable to play the second (with 2 layers).
The command I used is `MP4Client out.mp4` for the first version, and although it plays out the video, I get the following error in terminal:
`[Compositor2D] Cannot attach video surface memory to raster: Feature Not Supported`
For the second version: `MP4Client out2l.mp4` the video doesn't play at all, and I get the following in the terminal:
`[Codec] ODM1 ES2: Cannot find decoder for stream type MPEG-H L-HEVC Video
Stream Setup Failure: Media Codec not found
[Compositor2D] Cannot attach video surface memory to raster: Feature Not Supported`
Both videos are encoded using the same SHM12.3 software, the only difference is with the number of layers.
The two videos can be downloaded from [this link](https://drive.google.com/file/d/0BzO-c87ZZxWAUE53dGNFM3pCTEE/view?usp=sharing)
How can I add SHVC decoder to MP4Client? And why does this error show only when I have a video of 2 layers?
P.S. I can play both videos on VLC player

I have a sample taken from Blu-ray muxed to mp4 using mp4box. Playback in MPC-HC/LAV and ffplay is partly broken (it seems at least first and last 2(?) GOPs make screen grey and/or playback stop). When remuxing using ffmpeg -i "output.mp4" -c copy "remux.mp4" ffmpeg throws some errors:
```[mp4 @ 0000000002f0f020] Non-monotonous DTS in output stream 0:0; previous: -400

```
I have uploaded the sample to the MediaFire dropbox. To test I used a simple "_mp4box -add input.264 -output.mp4_". Version is latest nightly (gpac-0.7.2-DEV-rev175-ga99b084-master-win32.exe).
FWIW mkvtoolnix also had problems with this Blu-ray that now got fixed. Maybe their findings can give you a hint about what's going wrong:

After some time running the video is freezed. In my opinion there is something wrong with the the audio video sync but I don't now what is the reason; or maybe It has to do with the GOP length and the -dash-live parameter. The Average GOP length is 48 samples and I was running the following MP4Box command:
`MP4Box -subdur 6000 -dash-live 2000 -profile "dashavc264:live" -mpd-title "DASH-LIVE stream" -rap -frag-rap -insert-utc -mpd-refresh 6 -time-shift 6 -min-buffer 2000 -bs-switching no -segment-name piece_live%s -dynamic -out reencoded_audiolive.mpd reencoded48_audio.mp4#video reencoded48_audio.mp4#audio`
I read the @rbouqueau article https://gpac.wp.imt.fr/2015/11/02/check-key-frame-alignment-with-mp4box/ but I didn't understood how to configure the GOP and the dash-live DUR parameters. Could someone help me with the relation between GOP and DUR and how to fix this? Thanks!

Detailed guidelines: http://gpac.io/2013/07/16/how-to-file-a-bug-properly/
I am having a problem where mp4box exits early when trying to dash live. My setup is as follows:
A "remote client" streams from a webcam with ffmpeg:
ffmpeg -f dshow -i video="HP HD Webcam" -f dshow -i audio="Microphone (Realtek High Definition Audio)" -c:v libx264 -r 30 -rtbufsize 100M -f mpegts -movflags frag_keyframe+empty_moov -frag_duration 2 -force_key_frames expr:gte(t,n_forced*2.0) -c:a aac udp://localhost:8080/liveTest
The server reads the stream with ffmpeg, and saves it to a file:
ffmpeg -i udp://localhost:8080/liveTest -c:v libx264 -rtbufsize 100M -an -f mp4 -movflags frag_keyframe+empty_moov -frag_duration 2 -force_key_frames expr:gte(t,n_forced*2.0) d:\test\out.video.mp4 -c:a aac -vn -frag_duration 2 d:\test\out.audio.mp4
And mp4box dashes the video/audio for the DASH-IF player:
MP4Box -dash-live 2000 -rap -frag-rap -subdur 2000 -profile "dashavc264:live" -bs-switching no -dynamic -mpd-refresh 60 -time-shift 10800 -insert-utc -out d:\test\liveTest.mpd d:\test\out.video.mp4 d:\test\out.audio.mp4
Note: I am testing this on a single machine, so the remote client and server are the same for right now.
MP4Box runs for a few iterations, but always exits with an "Error DASHing file: Bad Parameter":
D:\test>mp4box.exe -dash-live 2000 -rap -frag-rap -subdur 2000 -profile "dashavc264:live" -bs-switching no -dynamic -mpd-refresh 60 -time-shift 10800 -insert-utc -out d:\test\liveTest.mpd d:\test\out.video.mp4 d:\svt\videos\aLiveT

Error while DASH-ing file: Bad Parameter
Error DASHing file: Bad Parameter
I ran this in the debugger, and the Bad Parameter error comes from the file stbl_read.c, from the line:
'''
if (SampleNumber > sdep->sampleCount) return GF_BAD_PARAM;
'''
I noticed before the Bad Parameter error, there was always a previous DASH iteration that dashes less than the expected 2s segment. (In the above example, one iteration only dashes 0.4667 of the 2s segment). I wonder if that is the real cause of the problem, and after that happens mp4box is out of sync. I checked the source video, and verified there are I-frames at every 2s, and nothing in between, so I don't know why mp4box segments at 0.4667s.
The above results are from a code I built today (27-Jun-2017). Note I built from the gpac_mp4box_mini.sln.
Also note I don't have the same problem with an old 0.5.2 build from a long time ago. That build will continue DASHing the file indefinitely. However, I have a different problem with that build, where it seems mp4box DASHes slightly slower than the playback, so the player eventually gets ahead of the available segments and stops playing. But that's an old build, and I figure everyone would rather focus on the problem with the most recent build.

DASH specifies a normative XSD with a fixed order of elements. It requires ContentProtection to be present before Role. However, mp4box generates the opposite order.
Version: gpac-0.7.2-DEV-rev133-g732afbe-master-x64
Command: `mp4box.exe -dash-strict 4000 -out out/Manifest.mpd -profile "dashavc264:live" -bs-switching no video-H264-288-400k.mp4:role=main`
Input files: [video-H264-288-400k.zip](https://github.com/gpac/gpac/files/1084433/video-H264-288-400k.zip)
Expected behavior:
```xml
<AdaptationSet segmentAlignment="true" maxWidth="512" maxHeight="288" maxFrameRate="24" par="16:9" lang="und">

Hi,
I have 264mb of M4A files that I am trying to concate into a single file using the `-cat` option.
Unfortunately I only have 500mb of useable space (it's an AWS Lambda function) and so I collect the files one at a time, 'cat' them into the growing combined file, then clean up.
This works great until I get close to the 250mb mark, at which point the temp file cannot be created.
Is there any way to 'cat' the files directly into the target, without creating a temp file first? All the files are 100% the same in encoding, frequency, channels.
Many thanks,
Geoff

Greetings,
I followed this blog post to generate a MPEG DASH tiled HEVC stream: https://gpac.wp.imt.fr/2016/05/25/srd/
So, now i have the mpd and m4s files for each tile each second with different qualities.
I would like to ask how i can choose offline a prespecified qualities for each tile each second and decode these tile qualities each second and concatenate them to produce a YUV stream or even an HEVC stream of different tile qualities that i can use an HEVC decoder to get the YUV file.
So, can i use the source code APIs to do such a thing ?
Best Regards,
Omar Eltobgy

Hello there,
I am running DashCast on the server side for VoD streaming, and the bitrates (250,500,1000,2000Kbps) are done via a config file.
I want to do further evaluation but I want to get the size (bitrate) of each frame once the segmentation is occur.
Is there any way I can extract all frames or segments' information from either DashCast command line or in MP4Client?
Thanks
Irrz

I am sure that _GPAC 2D Raster_ was checked during the installation.
On the same PC, version 0.6.1 worked fine.
Thanks for any feedback!

Apple has already supported fragment MP4. According to https://developer.apple.com/videos/play/wwdc2016/504/ this video, the Fairplay encryption mode of fragment MP4 should be 'cbcs'. In addition to this, I can't find any demo or tutorial about 'cbcs' working with fragment MP4.
Can mp4box encrypt MP4 file for Fairplay?
Thanks

Hello there,
I am running DashCast on the server side for VoD streaming, and the bitrates are done via a config file.
I want to do further evaluation but I want to get the size (bitrate) of each frame once the segmentation is occur.
Is there any way I can extract all frames or segments' information?
Thanks
Irrz

MP4Box inserts both $Number$ and $Time$ substitutes to the media url mask value. Segment files use a 1..n sequence numbers (1080p_i.mp4, 1080p_1.m4s, 1080p_2.m4s, 1080p_3.m4s ...).
Manifest works fine if I remove $Time$ variable from the value, see manifest.mpd test link above.

(Windows 10, 64bit)
Run git pull to update most recent files, media-autobuild_suite.bat script fails on the libbluray compilation.
**Java class versions** J2SE8 = 52, J2SE7 = 51
I have the following folders but just JDK1.7 is installed and be visible in winregistry. JDK1.8 folder is unzipped without running setup.exe (zero-installation scheme).
C:\Program Files\Java\jdk1.7.0_75
C:\Program Files\Java\jdk1.8.0_112
**Winregistry**
```
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\
CurrentVersion=1.7
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\1.7
JavaHome=C:\Program Files\Java\jdk1.7.0_75
```
I suspect build scripts take JDK1.8 folder and libbluray fails or some of the compilations use JDK1.8 and some part JDK1.7 thus creating a mismatch in class version magic number.
Helper function `build/media-suite_helper.sh/get_java_home()` is looking for registry value so it should take JDK1.7 release. I cannot verify which version was taken, script is using echo command to print value somewhere but none of the logfiles has it.
Is this a common problem and ideas to solve this? I cannot move jdk1.8 folder anywhere else at the moment actually windows locks a folder cannot even rename it.

Hi,
first of all, i'm not sure if this is a bug or a misuse of the tool. I've searched for similar issues and didn't find anything alike.
I´m trying to generate dash live streaming with ffmpeg and mp4box. I'm using ffmpeg to generate a file(black background with a burned TC) and then feed mp4box with the growing file.
Commands:
`ffmpeg -re -f lavfi -i color=s=nhd -map 0:v -filter_complex drawtext="fontfile='FreeSans.ttf':timecode='00\:00\:00\:00': r=25: x=(w-tw)/2: y=(h-th)/25: fontcolor=white: fontsize=42: box=1: boxcolor=0x00000099" -vcodec libx264 -g 1 -b:v 800k -pix_fmt yuv422p -movflags empty_moov+omit_tfhd_offset+frag_keyframe+default_base_moof -f mp4 -frag_duration 2 -y /tmp/longTC_2.mp4`
`mp4box -dash-live 2000 -fps 25 -frag 1000 -profile "dashavc264:live" -mpd-title "DASH-LIVE stream" -rap -frag-rap -insert-utc -mpd-refresh 30 -time-shift 1200 -min-buffer 2000 -bs-switching no -out /streaming/live/dash.mpd /tmp/longTC_2.mp4:role=main`
Also tested with:
`mp4box -dash-ctx /streaming/live/dash-live.txt -dash-live 2000 -profile "dashavc264:live" -mpd-title "DASH-LIVE stream" -ast-offset 12 -no-frags-default -rap -frag-rap -insert-utc -mpd-refresh 30 -time-shift 1200 -min-buffer 2000 -bs-switching no -out /streaming/live/dash.mpd -subsegs-per-sidx -1 /tmp/longTC_2.mp4:role=main`
(and multiple variants: -last-dynamic, add id to period, long etc )
The result is always the same, when the live session is launched, mp4box packages the whole mp4 file generated by ffmpeg available at the moment and goes to slept until the next iteration (the next lines corresponds to an execution that the file already had 1m1s of duration )
> Live DASH-ing - press 'q' to quit, 's' to save context and quit
Next generation scheduled in 61338 ms (DASH time 61520 ms)
In the next scheduled:
> Live DASH-ing - press 'q' to quit, 's' to save context and quit
Next generation scheduled in 61338 ms (DASH time 61520 ms)
Slept for 2665038 ms before generation
Next generation scheduled in 61492 ms (DASH time 123040 ms)
The result is that the segments are being regenerated from the beginning of the file (it looks like it's resetting the file pointer or not seeking to the last position ), so:
longTC_2_dash0.m4s has burned TC 00:00:00:00
and
longTC_2_dash30..3N.m4s has burned TC 00:00:00:00 again
If you concatenate all files and play them with ffplay (for example) you can see the loop:
`cat longTC_2_dashinit.mp4 $(ls -vx longTC_2_dash*.m4s) > fullfileconcat.mp4`
NOTE: the init file (longTC_2_dashinit.mp4) contains the box 'mvex' which in turn contains box 'mehd'. this box indicates the expected time of the segment set. This time is filled with the first available packet (in this case 61520) and never updated, so in order to play the concatenated file it would be necessary to open it with a hex editor and just skip this box.
I left in dropbox all the files that are generated and the concatenated one (loop_dash_live_issue_835)
Any ideas will be appreciated
This issue happens with the 0.7.0-rev0-gbd5c9af-master version and with the development branch from github. Tested both on windows 10 and ubuntu 16.04.
Thanks in advance and sorry for my bad english :)

Hi,
whenever I import H.264 elemtary streams using mp4box it says "_[avc-h264] Possible Variable Frame Rate: VUI "fixed_frame_rate_flag" absent._". This even happens with samples that do have said flag set to 1. I haven't seen any actual issues with the output files.
Sample "fixed_frame_rate_flag_NOT_absent.264" uploaded to MediaFire.
mp4box is latest Windows nightly (gpac-0.7.2-DEV-rev67-g975c0eb-master-win32).
|
mp4box says "VUI "fixed_frame_rate_flag" absent." but it's actually not absent.

1. Encrypt input media -
```
~ Mp4box -crypt /Users/ani/work/input/crypt.xml -out output/enc-sintel-1024-video.mp4 input/sintel-1024-video.mp4
```
2. Create DASH chunks of encrypted media -
```
~ Mp4box -dash 2000 -profile simple -mpd-refresh 4.0 -rap -segment-name dash_$RepresentationID$_$Number output/enc-sintel-1024-video.mp4 -out output/play.mpd
```
Above workflow worked perfectly in `GPAC version 0.6.1-revrelease` but when I upgraded to `GPAC version 0.7.1-revrelease` encrypted DASH segments stopped working in my player (shaka player).
Are there any known issues? I would greatly appreciate any kind of help. Thanks!

Hello,
I am trying to encrypt files with mp4box. It works fine unless I use the same file path for input and output file. (I want it to overwrite the original file with the encrypted file). Following is the error I get:
```
~ Mp4box -crypt /Users/ani/work/mp4box-crypt/input/crypt.xml -out /Users/ani/work/archive/hd-00002.mp4 /Users/ani/work/archive/hd-00002.mp4

[Core] system failure for file opening of out_/Users/ani/work/archive/hd-00002.mp4 in mode w+b: 2
Error: I/O Error
Error: I/O Error
```
I am on `MP4Box - GPAC version 0.7.1-revrelease`. I am wondering if this is how it's supposed to work, or if it's a bug?

- [x] I looked for a similar issue and couldn't find any.
- [x] I tried with the latest version of GPAC. Installers available at http://gpac.io/downloads/gpac-nightly-builds/
- [x] I give enough information for contributors to reproduce my issue (meaningful title, github labels, platform and compiler, command-line ...). I can share files anonymously with dropbox (see links provided below).
Hello,
I have a 8-minute 360 video that is divided into 5x5 tiles. The video was prepared using the latest version of kvazaar. 2 representations are prepared - 500kbps and 5Mbps.
It is then converted into DASH format using the latest version of MP4Box with the following command:
`MP4Box -dash 2000 -profile live -out ba.mpd -segment-name segment/%s 500k.mp4 5M.mp4`
The whole video set (including MPD file and all segments) can be downloaded at:
https://www.dropbox.com/s/hvflbdx442r5y2g/blue-angel.tar.gz?dl=0
I'm streaming the video in a local network setup as follows:
[Server] <-> [Network Impairment Node] <-> [Client]
where the network impairment node is able to add delays and packet loss to the path (using standard Linux tc netem).
While MP4Client can play the video without any problem, I notice that no matter how poor the network is, MP4Client always chooses the 5Mbps representation and does not switch to a lower quality. This causes the video playback to stall every 2 seconds.
Looking into the log file (using MP4Client's dash@debug option), which can be downloaded at https://www.dropbox.com/s/39w79kkjfzoixw8/mp4client-400ms.log?dl=0
I can see the following output:
`[DASH] Rate Adaptation - download rate 11872 kbps - 3 quality levels (cumulated representations rate 5045 kbps)`
while the actual download throughput is less than 1Mbps, which is observed by running Wireshark on the client machine.
It's important to note that this issue seems to apply to SRD tiled video only. When I play non-tiled video using the same setup, MP4Client is able to correctly adapt representations based on network condition.
Thanks!
Chang
