When using DashCast for long periods, it eventually will stop working. The stream can originally be played in dash.js, but after a few hours it stops being playable. dash.js will HTTP request and load the segments closest to bleeding-edge/live, and then for some reason seek back about 10 minutes and load segments from then. In neither cases is any content playable. The stream is audio-only.
We're launching DashCast with this command:
`/usr/bin/DashCast -a "$URI" -live -conf /dashcast.conf -out /srv/dash -time-shift 300 -seg-dur ${DASH_SEGLENGTH} -frag-dur ${DASH_SEGLENGTH} -mpd ${INGEST_NAME}.mpd`
Where:
- URI is an Icecast stream, but the issue seems apparent when using other ffmpeg connections, formats, and codecs. The input is stable and realtime.
- DASH_SEGLENGTH is 5000 (5s)
In this cast, dashcast.conf looks like:
[a256]
type=audio
bitrate=256000
[a128]
type=audio
bitrate=128000
We're compiling DashCast against ffmpeg 3.3, all within a Docker container. This is available at https://github.com/InsanityRadio/AudioEngine/blob/a61b682246f481dd018f66ed134b51de6059a065/docker/dash/Dockerfile, so replicating the exact environment should be very straightforward.
According to logs,
- [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 ...).

The app both on Android and iOS downloaded from https://gpac.wp.imt.fr/downloads/gpac-nightly-builds/ could not work.
Each time I open it and type the URL, it crashes.
Besides, the iOS project in gpac/build/xcode/ will render black screen each time I execute it on my iphone6s. It does not show any buttons or pictures like the app provided, which is worse for debug.
If anyone has the same problem like this, please tell me how to fix it up. And I will be very appreciate for this. Thank you!

Hello,
Who knows why the APK(https://gpac.wp.imt.fr/downloads/gpac-nightly-builds/) cannot work well on any Android devices?
I have tried many Android devices (Google Pixel XL && Huawei Honor) and APK versions.
When I open an URL (DASH MPD file) after installing these APK, it will crash always.
Why?
To produce a new APK, I also have compiled the source code (master) by myself. However, it also will crash. I cannot play any profiles.
Yours Sincerely,
James Xu.

cbcs content from MP4Box doesn't play in Safari. cbcs content from Shaka Packager plays as expected. Moreover, neither Shaka Packager nor MP4Box is able to decrypt content from MP4Box. It seems that MP4Box incorrectly applies cbcs encryption.
Test content can be found here: https://1drv.ms/f/s!Ah-Kf_FqISskkmBLPzaAmoTccdM6
The playback of cbcs content can be tested in Safari (on iOS 11+ or macOS 10.13+). Since such content requires a decryption key, this key (cbcs.key) is provided to a media player through the media playlist (index.m3u8), so in Safari you need to navigate to the .m3u8 file, in order to play the video.
The cbcs content was created using the following command (the crypt.xml file is in /MP4Box):
```
mp4box.exe -crypt "cbcs\crypt.xml" "360p-750k.mp4" -out "cbcs\360p-750k.mp4"
```
Although here I mentioned only cbcs content, content encrypted other protection schemes may be affected as well, since such content also cannot be decrypted (see the issue https://github.com/gpac/gpac/issues/1047).

Hello,
For a project on adaptive 360 VR video streaming, I want to be able to merge the tiles of each segment back together into a full segment before displaying at the client.
To achieve this, I have encoded, tiled and dashed the video following these instructions (https://github.com/gpac/gpac/wiki/Tiled-Streaming). I have dashed a video of 10 seconds, 4 tiles and segments of 1 second. I have obtained a set of 5 init files (set1_init.mp4, track2_init.mp4, track3_init.mp4, track4_init.mp4) and a set of files with the extension .m4s corresponding to tile number and segment (for example, video_1_dash_track1_1.m4s).
The next step is to merge the tiles back into a video. I had expected to have an mp4 init file per segment and a set of m4s tiles, concatenate them with a cat command, extract the hevc with the raw command and repackage in MP4Box. However, I don't know how to do this with all the init files or which ones to use. I have had an extensive look for an explanation of the working principles of this but I have not succeeded so far.
Does anyone have a suggestion on how to manually merge the tiles back together into a playable segment?
Thank you,
Maria

MP4Box doesn't allow using 8 byte IVs while creating cbc1 content:
https://github.com/gpac/gpac/blob/02582a2236cb384d65442cc9856c3bc6cb993f3c/src/media_tools/ismacryp.c#L229
As a result, the warning `[CENC] Using AES-128 CBC: IV_size should be 16` is being shown, and MP4Box switches to using 16 byte IVs.
I guess this limitation comes from the second edition of the CENC standard. That being said, in the third version of the CENC standard, there's no such limitation anymore. According to the section 10, both 8 and 16 byte IVs are allowed for all protection schemes (cenc, cens, cbc1 and cbcs).

When I decrypt CENC content, MP4Box either crashes or hangs. This issue affects the usage of all protection schemes defined in the third edition of the CENC standard (cenc, cens, cbc1 and cbcs).
Test content and crypt.xml files can be found here: https://1drv.ms/f/s!Ah-Kf_FqISskkkmTypYhfJTqICJL.
I use the following command to encrypt content:
```
mp4box.exe -crypt "cenc\crypt.xml" "360p-750k.mp4" -out "cenc\360p-750k.mp4"
```
And the following command to decrypt it:
```
mp4box.exe -decrypt "cenc\crypt.xml" "cenc\360p-750k.mp4" -out "cenc\360p-750k-clear.mp4" -logs all@debug -lf "cenc\decrypt.txt"
```
I'm not sure whether logs show anything interesting, but you can find them together with the test content, in folders named after protection schemes (decrypt.txt files).
I also tried debugging this operation in Visual Studio, and it fails at: https://github.com/gpac/gpac/blob/42cd567b3e17b855e701854e0104c5b4b200d19e/src/isomedia/box_funcs.c#L1388
An exception is being thrown saying "read access violation, a->registry was 0xDDDDDDDD".
Speaking of crashes and hangs, I noticed that the crash happens when decrypting cenc, cbc1 and cens content. When I decrypt cbcs content, then MP4Box hangs.
I'm on Windows 10, 1709 (16299.371), using GPAC version 0.7.2-DEV-rev461-g01391a0c-master. Everything is 64-bit.

I'm using mp4box to create cenc encrypted dash stream. I have noticed that the SENC box is generated differently for audio segments depending on what size IV I use and I was hoping I could get feedback on why.
I'm using the latest dev nightly: 0.7.2-DEV-rev459-g07f44028-master
I saw same behavior with version 0.6.0 as well
**First case: 128bit IV**

$ MP4Box -dash ${DURATION_MS} -segment-name segment_%s -out ${OUTPUT_DIR}/output.mpd ${OUTPUT_DIR}/256kps.aac ${OUTPUT_DIR}/96kps.aac
In this setup with 128bit IV I get a SENC that has subsample decryption disabled (flags != 0x2) and I just have a list of IVs for each sample in the segment. This is what I would expect, the binary looks like:
`73 656e 6300 0000 0000 0000 d712 3456 7812 3456 7812 3456 7812 3456 7812 3456 7812 3456 7812 3456 7812 3456 8d`
The above translates to:
senc header: 0x73656e63
flags: 0x0
Num Samples: 0xd7
Sample IV: 0x12345678123456781234567812345678

Mp4Box Commands:

$ MP4Box -dash ${DURATION_MS} -segment-name segment_%s -out ${OUTPUT_DIR}/output.mpd ${OUTPUT_DIR}/256kps.aac ${OUTPUT_DIR}/96kps.aac
In this setup with 64bit IV I get a SENC that has subsample decryption enabled (flags == 0x2). I see an subsample encryption array for each sample with a single entry that lists 0 unencrypted bytes and all protected bytes. Example Binary is:
`73 656e 6300 0000 0200 0001 ae22 ee7d 4745 d3a2 6a00 0100 0000 0002 e722 ee7d 4745 d3a2 6b00 0100 0000 0002 e7`
The above translates to:
senc header: 0x73656e63
flags: 0x2
Num Samples: 0x1ae
Sample IV: 0x22ee7d4745d3a26a
Subsample Count: 0x1
BytesOfClearData: 0x0
BytesOfProtectedData: 0x2e7
Sample IV: 0x22ee7d4745d3a26b
Subsample Count: 0x1
BytesOfClearData: 0x0
BytesOfProtectedData: 0x2e7
So as you can see the 64bit IV is causing subsample encryption to be enabled and I don't understand why.
Can you please explain this difference?

If you happen to run twice a command like:
MP4Box -add file.264 -crypt drm_file.xml out.mp4
The second time, it fails with a "Bad Parameter" error, while it could fail with an error message: "Trying to encrypt an already encrypted track".

A couple of days ago, I asked if this was supported. I got an affirmative answer. Given that, I am trying to figure why I cant seem to get it to work. The sequence of steps I tried are listed
below
1) MP4Box -add sample.srt guardians.mp4
2) MP4Box -hint guardians.mp4
3) MP4Box guardians.mp4 -rtp -dst-rtp 235.10.11.12:1234
I get the following errors when I attempt to stream
Could not initialize RTP streamer: No error
Cannot create file streamer

I am trying to set segment duration while creating tiled DASH content for HEVC using kvazaar and MP4Box.
Regardless of what segment duration I give to MP4Box, the mpd file have value for **maxSegmentDuration** around **2 - 2.5 seconds**. I verified that the buffer occupancy also increases by **2 - 2.5 seconds** on arrival of the segment at the dash client. Is it a known issue/encoder's limitation or am I doing something wrong?
E.g
MP4Box -dash **1000** -profile live -out a.mpd video_tiled1.mp4 video_tiled2.mp4 video_tiled3.mp4 video_tiled4.mp4 video_tiled5.mp4
MP4Box -dash **5000** -profile live -out a.mpd video_tiled1.mp4 video_tiled2.mp4 video_tiled3.mp4 video_tiled4.mp4 video_tiled5.mp4

On Ubuntu 16.04
Displayed on video.js contrib dash
Browser Safari/Chrome
Hi there, I need a hand to identify how to fix this bug, i try to archive a live streaming with the command above:
> MP4Box -dash-live 2000 -subdur 4000 -profile dashavc264:live -mpd-refresh 4 -time-shift 16 -min-buffer 2000 -url-template -out manifest.mpd 1080set.mp4#video 720set.mp4#video 360set.mp4#video 1080set.mp4#audio 720set.mp4#audio 360set.mp4#audio
Now it's running on www.allibrante.com
-I use -dash-live of 2000 ms couse the GOP of encoding is every 2 seconds.
-I use min-buffer of 2000 ms as the -bufsize of the encoding is 2 second (4800 kbps * 2)
-I use -mpd-refresh to 4 second as the subdur (4000ms)
-I read that url-template for live is needed
The adaption sets are encoded with the following ffmpeg command line:
> ffmpeg -f concat -safe 0 -y -i list.txt -i ../logo/logo.png -c:a aac -b:a 384k -ar 48000 -ac 2 -c:v libx264 -x264opts keyint=50:min-keyint=50:no-scenecut -r 25 -b:v 4800k -maxrate 4800k -bufsize 9600k -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:10,scale=1920:1080,setsar=1" -t $TOTDUR ../output/1080set.mp4
> ffmpeg -f concat -safe 0 -y -i list.txt -i ../logo/logo.png -c:a aac -b:a 256k -ar 48000 -ac 2 -c:v libx264 -x264opts keyint=50:min-keyint=50:no-scenecut -r 25 -b:v 2400k -maxrate 2400k -bufsize 4800k -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:10,scale=1280x720,setsar=1" -t $TOTDUR ../output/720set.mp4
> ffmpeg -f concat -safe 0 -y -i list.txt -i ../logo/logo.png -c:a aac -b:a 128k -ar 48000 -ac 2 -c:v libx264 -x264opts keyint=50:min-keyint=50:no-scenecut -r 25 -b:v 800k -maxrate 800k -bufsize 1600k -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:10,scale=640x360,setsar=1" -t $TOTDUR ../output/360set.mp4
I verified that the gop was aligned with ffmpeg and mp4box, it' correct.
If i try without -subdur flag, the ABR work properly: trying with chrome/performance to reduce the bandwith it is capable to switch when needed.
I use subdur to avoid using too much memory: I dont need to make all the segments available at same time.
Actually the streaming try to load the most expensive rapresentation over and over again.
May i ask a help to understand what is going on here?
Thanks a lot!
Dan

I’m trying to create a tiled HEVC/H.265 MPEG DASH video that allows for changing quality of a tile in the multi-tiled video.
So far I’m able to play and change the quality of a tile in the demo video provided on: http://download.tsi.telecom-paristech.fr/gpac/SRD/srd_hevc/multi_rate_p60/
I’m creating my own test videos with the commands found in these tutorials:
https://gpac.wp.imt.fr/2017/02/01/hevc-tile-based-adaptation-guide/
https://github.com/gpac/gpac/wiki/Tiled-Streaming
The exact commands I used in order are:
```
.\kvazaar.exe -i test.yuv --input-res 3840x2160 -o output_qp22.hvc --tiles 3x3 --slices tiles --mv-constraint frametilemargin -q 22 --period 24 --input-fps 24`
.\kvazaar.exe -i test.yuv --input-res 3840x2160 -o output_qp37.hvc --tiles 3x3 --slices tiles --mv-constraint frametilemargin -q 37 --period 24 --input-fps 24`
MP4Box -add output_qp22.hvc:split_tiles -fps 24 -new output_qp22.mp4
MP4Box -add output_qp37.hvc:split_tiles -fps 24 -new output_qp37.mp4
MP4Box -dash 5000 -rap -frag-rap -profile live -out .\two_qualities\dash_tiled.mpd output_qp22.mp4 output_qp37.mp4
```
When I run my own generated content in the player and change the quality of one tile (tile 6 in this case) I get this as a result:
Am I using a wrong setting when generating the content? What am I doing wrong while generating the content? I also noticed that in the provided demo there is only one track1 while my generated content has 2 in the MPEG-DASH context.
Any help is much appreciated.
Tested versions:
Kvazaar 1.1.0
MP4Box - GPAC version 0.7.0-rev0-gbd5c9af-master
MP4Box - GPAC version 0.7.2-DEV-rev449-g4c3f4423-master
I get not errors/warnings while generating the content. All commands are executed on Windows 64-bit.

**ISSUE CONTENT**
This issue originates at https://github.com/CCExtractor/ccextractor/issues/961
**Video file:** *https://drive.google.com/file/d/1MyABc8cByEWcW9wQkl_Y_JIUYGC-Kd_5/view?usp=sharing*
MP4 recorded from a drone (specifically: "Zenmuse camera on a DJI Inspire 2 Drone"). The telemetry data is saved as subtitles and in fact VLC can display it.
Using MP4Box from libGPAC to extract information from the MP4 file fails with the following error,
**Background:**
At CCExtractor we use libGPAC to process MP4 files and extract subtitles from them and we have failed at this file. The problem seems that libGPAC is not able to process the file and thus throws an error.
**To reproduce:**
- Download the video file
- Install MP4Box
- Use the following command from the video file's directory
```
MP4Box -info DJI_0019.MP4
```

I met many cases which have the same issue as this one:
I have an original video, then
in path 1, I do a simple remux and get an output (I call
passthrough_sd.mp4)
in path 2, I do a transcoding with exact IDR alignment as original and get an output (I call passthroughaligned_sd.mp4)
These two output have the exact IDR and PTS info. Run ffprobe,
`ffprobe -hide_banner -i v4_passthrough_dash.mp4 -select_streams v -show_frames -show_entries frame=key_frame,pict_type,pkt_pts_time -print_format csv | grep 'I'|grep 'frame,1'`
frame,1,0.000000,I
frame,1,1.100000,I
frame,1,2.101667,I
frame,1,3.101667,I
frame,1,4.103333,I
Then I apply mp4box to both outputs with command (I am using MP4Box - GPAC version 0.7.2-DEV-rev386-gc66782d8-master)
`MP4Box -dash 2000 -profile dashavc264:onDemand -bs-switching no -rap -frag-rap -out input.mpd input.mp4
`
I get DASHed files for both, but their IDR and PTS differ
for passthrough_sd.mp4, after DASH, ffprobe show the same as before DASH:
frame,1,0.000000,I
frame,1,1.100000,I
frame,1,2.101667,I
frame,1,3.101667,I
frame,1,4.103333,I
but for passthroughaligned_sd.mp4, it has very different IDR and PTS:
rame,1,0.000000,I
frame,1,1.100000,I
frame,1,2.968333,I
frame,1,3.970000,I
What is it about these two files that result in complete different IDR after DASH? Is there anything I can do in remux stage for the first output to make the IDR align after DASH? Thank you!

Now I'm working on making a 360 video player on Android. My goal is to partially load the video adaption set by DASH feature SRD to save bandwidth, in the codec of HEVC by the way. I have tried a lot open source project and find mp4client on PC is able to play the HEVC, tiled, DASH video, which is not available by others like Dash.JS.
So now I'm compiling on the android version on my Windows, but having no idea how to custom my own algorithm. Should I directly rewrite dash_cilent.c, or in other ways? The doc on the official website teaches us to use ant to package the APK, does there any way to use IDE like Android studio?

I am trying to debug gpac code using GDB. I ahve configured with ./configure --enable-debug. After that when I was trying to put break point it is showing **no debugging symbols** found.
**file bin/gcc/MP4Client** command is also displaying no debugging symbols found.
How can I resolve this ?
Thanks

I added a new module written in c++ inside media_tools folder that I am calling from dash_client in Ubuntu 16.04. I am not able to set correct flags in Makefile in src folder. Can you please tell me the modification that I should do in Makefile to link and compile correctly.

I have this input progressive file(attached), and when I use the following mp4box command to convert it to dash, it gives me this weird codec name for video: codecs="avc1.640015,tmcd"
`MP4Box -dash 2000 -profile dashavc264:onDemand -bs-switching no -rap -frag-rap -out v4_passthrough.mpd v4_passthrough_sd.mp4
`
My player cannot recognize this video codec so it fail to play.
I looked into the input stream, tmcd is the codec_tag_string of the data stream. How could this tag string got into the video codec in mpd? Is there any option to avoid this?
I use MP4Box - GPAC version 0.7.2-DEV-rev386-gc66782d8-master

Hello,
I'm currently experimenting/testing with MP4box and heif/heic and would like to know if the following is possible or not :
Right now i can add the first frame from a video into a heic , like :
`MP4Box -add-image "H:\video1.hvc":primary:name="Frame1" -ab heic -new "H:\image.heic"`
Or first frame from 2 different videos sources into a single heic , something like :
`MP4Box -add-image "H:\video1.hvc":primary:name="Picture1" -add-image "H:\video2.hvc":name="Picture2" -ab heic "H:\image.heic"`
I also read about _file.hvc:time=1.2_ that will import _the next IDR frame_ after the given time :
`MP4Box -add-image "H:\video1.hvc":primary:name="Frame1":time=1.2 -ab heic -new "H:\image.heic"`
But what i will be interested in is selecting the frame(s) i want from a given video, either by specifying the frame number of the desired frame(s) or the timestamp where the frame i want is located ( maybe as _00:00:00:000_ timestamps, frame number will be simpler tho, something like _:framepos=150_ maybe, the number being the frame position desired to be extracted from the the video and sent to the heic file, also something like this could be a solution for multiple frames in a single command _:framepos="100,200,500,1000"_ )
I don't know if this is possible for now and i am maybe missing the correct infos/documentation to achieve this or if it is simply not possible with MP4Box,
If it isn't possible then please consider this as a request feature that could bring something very interesting to this container format used within MP4Box.
Thank you for any hints or help,
Merci d'avance :)

______________________
Hello,
Using latest nightly build _gpac-0.7.2-DEV-rev438-gc107b22d-master-x64.exe_ from your website and _win7 x64_
From windows command prompt I'm trying to use _-dump-item_ to drop the files into specific locations :
`MP4Box -dump-item 1:path="H:\item1.hevc" "H:\image.heic"`
This returns :
```
[IsoMedia] Extracting item type not supported
Error: Feature Not Supported
```
The following ones work :
```
MP4Box -dump-item 1:path=item1.hevc "H:\image.heic"
MP4Box -dump-item 1:path="item1.hevc" "H:\image.heic"
MP4Box -dump-item 1:path="..\item1.hevc" "H:\image.heic"
```
_(last one correctly drops the file into MP4Box parent folder)_
I suspect the colon in the path is the problem, i tried the few variations i know to escape the paths but no dice until now and running out of ideas so i came here to ask if a good soul have an idea about this or if it's somehow not possible to get this working like i want
Thank you very much,
Merci d'avance :)

# Problems
I find there are two problems in this lastest branch.
- mp4box : generating Dash content
- mpclient : display problem during playing video after using mp4box to remove some tracks.
# Enviroment configuration:
- Operation System: Windows 10
- Kvazaar version: 1.1
- branch: the lastest
## mp4box problem
According the wiki [Tiled Streaming](https://github.com/gpac/gpac/wiki/Tiled-Streaming), I use mp4box to generate dash content based on tiles. My steps are shown in following words.
### step one ：
`kvazaar -i input.mp4 --input-res 3840x2160 -o output.hvc --tiles 6x6 --slices tiles --mv-constraint frametilemargin -q 30 --period 30 --input-fps 30`
### step two：
`MP4Box -add video_tiled.hvc:split_tiles -fps 30 -new outspace_1M.mp4`
### step three:
`MP4Box -dash 1000 -rap -profile live -out dash_tiled.mpd outspace_1M.mp4`
As seen from above, the duration of input.mp4 is about one minute and the duration of segment is 1 second. Hence, there will 60 segments for each track(37=36+1). However, I'm surprised at I just get one segment for each track, which is similar as OnDemand profile.
## mp4client problem
According [HEVC Tile-based adaption guide](https://gpac.wp.imt.fr/2017/02/01/hevc-tile-based-adaptation-guide/), I try to play video after removed some tracks by mp4box. My steps are shown in following words.
### step one:
`MP4Box -rem 3 video_tiled.mp4 -out test_tile_lost.mp4`
### step two:
`mp4client test_tile_lost.mp4`
### Outcome
Theorically, the outcome should be like this. However, tracks whose id bigger than 3 won't be displayed.
Glad to see your response!

I am Using GPAC source code for my Project. I am calling gf_dash_setup_period() defined in src/media_tools/dash_client.c from applications/mp4client/main.c by including it in header file dash.h.
However Im unable to make it as I am getting "Undefined reference to gf_dash_setup_period ". It is getting compiled properly and object file is getting generated.
But there is problem while linking and main.o is failing. MakeFile also seems to be proper. Can I get any lead on this issue of how to resolve and proceed further ?

Hello everyone, testing my live manifest on ITEC validator I receive a warning:
> If more than one Media Segment is present the duration attribute or SegmentTimeline element shall be present.
By adding `-segment-timeline` on my MP4Box command:
`MP4Box -dash-live 8000 -subdur 8000 -bound -profile dashavc264:live -mpd-refresh 3600.0 -time-shift 24 -min-buffer 4000 -insert-utc -no-cache -segment-timeline -out manifest.mpd 1080set.mp4#video 720set.mp4#video 360set.mp4#video 1080set.mp4#audio 720set.mp4#audio 360set.mp4#audio`
I get the following error at the start of the process and it's impossible to display the streaming:
> [DASH] Drift between minCTS of segment and MPD start time is 0.0209375 s
Cheking PTS of my input video file i get:
0.021016
2.021016
4.021016
6.021016
8.021016
[...]
I notice a delay at start that i think could be the issue.
What do you think about, may be due to PTS delay?
I have to correct my encoding or it can be considered an issue of mp4box?
Thanks a lot!

Hello.
As far as I know, MP4Box ttxt format supports subtitle screen positioning, but I just can’t get it to work.
I want a subtitle to appear at top of the screen. But regardless of "top" attribute I set in ttxt, it’ll always appear at bottom.
Sample from `http://gpac.sourceforge.net/downloads/ttxt_sample_streams.tar.gz` also doesn’t seem to work (3GP_test_08.ttxt), QuickTime Player always shows "Unknown error -12710".
MP4 file was made using MP4Box `gpac_0.7.2-DEV-rev434-g9d4fd39b-master_amd64` official nightly build on Ubuntu 16.04 LTS 64 bit.
The file was tested in QuickTime Player on latest macOS High Sierra (version 10.13.) and MP4Client from the same build.
Is it a bug or I’m doing something wrong?
Any help will be appreciated.
Best regards.

In our use case, we are very picky about IDR and PTS alignment, so DASH should have the same number of IDR and PTS as input. Could you advise what's impacting IDR in mp4box and how can we fix it? I attached input.mp4 for your reference. Thanks!

I segmented a file using dash into segment files and for each keyframe in the segment the size is always bigger than the actual frame size in the original mp4. In he case of my files the differenci in size is 37 bytes:
00 00 00 19 67 4D 40 1F EC A0 28 02 DD 80 88 00 00 03 00 08 00 00 03 01 84 78 C1 8C B0 00 00 00 04 68 EF BC 80
What do these bytes represent?

Hi there! This night I put online the MP4Box based media server for live streaming:
http://178.63.175.10/
I can not get the adaptive bit-rate behavior,
the stream is unstable and stops before displaying the correct adaption set.
Check keyframes allignment i get:
`MP4Box -info 0 1080set.mp4 2>&1 | grep GOP`
**Average GOP length: 50 samples**
The command line i use is:
`MP4Box -dash-live 8000 -subdur 8000 -bound -profile dashavc264:live -mpd-refresh 3600.0 -time-shift 24 -min-buffer 4000 -insert-utc -no-cache -out manifest.mpd 1080set.mp4#video 720set.mp4#video 360set.mp4#video 1080set.mp4#audio 720set.mp4#audio 360set.mp4#audio`
May i ask a special help to understand whats going here?
Thanks

According the wiki [Tiled Streaming](https://github.com/gpac/gpac/wiki/Tiled-Streaming), I use mp4box to generate dash content based on tiles. My steps are shown in following words.
### step one ：
`kvazaar -i input.mp4 --input-res 3840x2160 -o output.hvc --tiles 6x6 --slices tiles --mv-constraint frametilemargin -q 30 --period 30 --input-fps 30`
### step two：
`MP4Box -add video_tiled.hvc:split_tiles -fps 30 -new outspace_1M.mp4`
### step three:
`MP4Box -dash 1000 -rap -profile live -out dash_tiled.mpd outspace_1M.mp4`
As seen from above, the duration of input.mp4 is about one minute and the duration of segment is 1 second. Hence, there will 60 segments for each track(37=36+1). However, I'm surprised at I just get one segment for each track, which is similar as OnDemand profile.
## mp4client problem
According [HEVC Tile-based adaption guide](https://gpac.wp.imt.fr/2017/02/01/hevc-tile-based-adaptation-guide/), I try to play video after removed some tracks by mp4box. My steps are shown in following words.
### step one:
`MP4Box -rem 3 video_tiled.mp4 -out test_tile_lost.mp4`
### step two:
`mp4client test_tile_lost.mp4`
### Outcome
Theorically, the outcome should be like this. However, tracks whose id bigger than 3 won't be displayed.
Glad to see your response!

I'm trying to tile multiple videos using kvazaar and then encode it through MP4Box, I'm unable to figure out what I'm doing wrong here, as the output video is not playable.
Step 1) Tile a video
```kvazaar -i input_1280x720.mp4 --input-res 1280x720 -o output_1280x720.hvc --tiles 6x4 --slices tiles --mv-constraint frametilemargin --input-fps 30 -q 30 -p 30```
Step 2) Encode a video
```MP4Box -add output_1280x720.hvc:split_tiles -fps 30 -new output_1280x720.mp4```
Once the above steps are executed, a tiled mp4 video is expected, which can be dashed using MP4Box with different resolutions of the same video.
```MP4Box -dash 1000 -rap -frag-rap -profile live -out dash_tiled.mpd output_1280x720.mp4 output_1920x1080.mp4 output_2560x1440.mp4```
I am unsure if I am doing something incorrect fundamentally here. Appreciate your help!

Hi,
While playing HEVC SRD tiles in Mp4client, it is possible to get tile numbers that are in current view in 360 mode inside compositor.c or any other relevant file.

Hey, it must be funny that mp4client works with head mounted device such as Oculus Rift. The primitive idea is to modify or add code in the following module:
- input_sensor
- compositor
However, I still don't know exact way.

The following steps are used to generate dash content:
- `kvazaar -i input.mp4 --input-res 3840x2160 -o output.hvc --tiles 6x6 --slices tiles --mv-constraint frametilemargin -q 30 --period 30 --input-fps 30
`
- `MP4Box -add video_tiled.hvc:split_tiles -fps 30 -new outspace_1M.mp4`
- ` MP4Box -dash 1000 -rap -frag-rap -profile live -out dash_tiled.mpd outspace_1M.mp4 `
the following is description of tools:
- kvazaar version :1.1
- mp4box version：0.7.0
- OS: windows 10
However, there might be a problem. More specially, `video_tiled.mp4 ` make up of 2800 frames and the `fps` is `30`. Hence, each segment should contain metadata of 200 frames except init.mp4 beacuse the duration of segment is 1 second. However, I find each tile only has one track containing metadata of 2800 frames. In other word, for example, each tile should contain 14(2800/200)segments not one segment.
the outspace_1M is in here.

The stack buffer overflow occurs [here](https://github.com/gpac/gpac/blob/master/src/media_tools/av_parsers.c#L2387-L2388):
```
sps->poc_cycle_length = bs_get_ue(bs);
for(i=0; i<sps->poc_cycle_length; i++) sps->offset_for_ref_frame[i] = bs_get_se(bs);
```
I don't know exactly how `bs_get_ue` works, but it seems to return a `u32`. The size of `offset_for_ref_frame` is only 256 entries, so we can get this to overflow. The sps variable is a stack variable that comes from a parent function, for example in `avcc_Read`.
Using this bug, I can craft an MP4 file that can overwrite anything above this variable in the stack, such as other fields in `AVC_SPS`, stack variables, etc.

Hi there, testing the latest version with the addition `-bound` with `-dash-live`
I can notice a problem of audio / video synchronization that occurs only after some loops of the video in input:
The problem starts to occur only when the loop begins repetitions:
For example if I watch a video of 20 minutes, audio and video are synchronized, when the video repeats its self as desired with -dash-live the delay between audio and video begins to grow, which will become evident after 3, 4 repetitions.
if I reload the page the audio will be back synchronized.
The problem is only visible after the repetition of several loops.
There are no errors from mp4box or on chrome console.
The test was performed with video.js contrib dash.
**command:**
`MP4Box -dash-live 8000 -subdur 8000 -bound -profile dashavc264:live -mpd-refresh 3600.0 -time-shift 24 -min-buffer 4000 -insert-utc -no-cache -out manifest.mpd 1080set.mp4#video 720set.mp4#video 360set.mp4#video 1080set.mp4#audio 720set.mp4#audio 360set.mp4#audio`
Apart from the additional information, I think there is a small difference in duration between audio and video that grow with the increase of repetitions, it is not reported by MP4Box, after some repetitions it becomes audible, reloading the page brings the streaming back synchronized.
It would seem that `-bound` has no effect while someone is watching?!
**Additional:**
Videos that i use for test is the concatenation (ffmpeg concat demux) of many videos prevoiusly encoded with closed gop, unfortunately I still can not get a timestamp without any discrepancies between one video and another
**encode command:**
`ffmpeg -y -i "$f" -i ../logo/logo.png -c:a aac -b:a 384k -ar 48000 -ac 2 -async 1 -c:v libx264 -x264opts keyint=$GOP:min-keyint=$GOP:no-scenecut -bf 0 -r $FPSC -b:v 4800k -maxrate 4800k -bufsize 3000k -profile:v main -crf 22 -t $DUR -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:10,scale=1920:1080,setsar=1" ../buffer/${NAME}-1080.mp4`
**concat command:**
`ffmpeg -f concat -safe 0 -i 1080list.txt -t $TOTDUR -c copy ../output/1080set.mp4`
**PTS timestamp:**
```
[...]
382.021016
384.021016
386.021016 the concat demux effect:
388.043047
390.043047
392.043047
[...]
```
For the the full script to encode and concat:
https://stackoverflow.com/questions/48770268/bash-script-automate-ffmpeg-encoding-for-mpeg-dash/48776153#48776153
**If you need i can upload the video used for test**
Thanks!

answered in "https://github.com/gpac/gpac/issues/979"
Quick question:
I am trying to install openHEVC and gpac.
they work fine together for gpac 0.5 and 0.6, but today for 0.7.2, gpac will not see openHEVC, when I run ./configure.
openHEVC installs perfectly, with "sudo make install" output as:
-- Install configuration: "RELEASE"
-- Installing: /usr/local/include/openHevcWrapper.h
-- Installing: /usr/local/include/hevcdsp.h
-- Installing: /usr/local/include/hevcpred.h
-- Installing: /usr/local/lib/libLibOpenHevcWrapper.a
Note: "libLibOpenHevcWrapper"
I did notice in 0.7.2, in ./configure, you have:
#look for openhevc support
if test "$darwin" = "yes" ; then
ohevc_cflags="-I/usr/include -I/usr/local/include"
ohevc_ldflags="-L/usr/lib -L/usr/local/lib -lopenhevc -lm -lpthread "
elif test "$cross_prefix" = "" ; then
ohevc_cflags="-I/usr/include -I/usr/local/include"
ohevc_ldflags="-L/usr/lib -L/usr/local/lib -lopenhevc -lm -lpthread"
else
ohevc_cflags="-I${prefix}include"
ohevc_ldflags="-lopenhevc -lm -lpthread"
fi
cat > $TMPC << EOF
#include <stdio.h>
#include <libopenhevc/openhevc.h>
int main( void ) { oh_init(1, 1); return 0; }
EOF
if docc $ohevc_cflags $ohevc_ldflags $LDFLAGS ; then
has_openhevc="yes"
else
ohevc_cflags="-I$local_inc"
ohevc_ldflags="-lopenhevc -lm -lpthread"
if docc $ohevc_cflags $ohevc_ldflags $LDFLAGS -L$local_lib ; then
has_openhevc="yes"
ohevc_ldflags="-L$local_lib $ohevc_ldflags"
fi
fi
while in 0.6, you check with:
#look for openhevc support
if test "$darwin" = "yes" ; then
ohevc_cflags="-I/usr/include -I/usr/local/include"
ohevc_ldflags="-L/usr/lib -L/usr/local/lib -lLibOpenHevcWrapper -lm -lpthread "
elif test "$cross_prefix" = "" ; then
ohevc_cflags=""
ohevc_ldflags="-lLibOpenHevcWrapper -lm -lpthread"
else
ohevc_cflags="-I${prefix}include"
ohevc_ldflags="-lLibOpenHevcWrapper -lm -lpthread"
fi
cat > $TMPC << EOF
#include <stdio.h>
#include <openHevcWrapper.h>
int main( void ) { libOpenHevcInit(1, 1); return 0; }
EOF
if docc $ohevc_cflags $ohevc_ldflags $LDFLAGS ; then
has_openhevc="yes"
else
ohevc_cflags="-I$local_inc"
ohevc_ldflags="-lLibOpenHevcWrapper -lm -lpthread"
if docc $ohevc_cflags $ohevc_ldflags $LDFLAGS -L$local_lib ; then
has_openhevc="yes"
ohevc_ldflags="-L../../$local_lib $ohevc_ldflags"
fi
fi
The change from "lLibOpenHevcWrapper" to "lopenhevc", which is also reflected in "openhevc_dec.c", with checks for "#include <libopenhevc/openhevc.h> and openhevc" and "#include <openHevcWrapper.h> and libLibOpenHevcWrapper", for 0.7 and 0.6 respectively.
Is there a new openHEVC that should be downloaded? rather than at:

There is an out of bounds heap write in av_ext.c: https://github.com/gpac/gpac/blob/master/src/isomedia/avc_ext.c#L2415
`op->layer_count` is read from user input, and then used in the condition of the for loop. This means the user can force the loop to execute up to 256 times. The `layers_info` array only has 64 elements, and this array is allocated on the heap, so I can craft a file that causes this file to write out of the bounds of the array onto the heap. For example, an attacker could overwrite the top chunk of the glibc heap, which can be used with other bugs to achieve remote code execution in services processing user supplied media files.

I have looked at:
https://github.com/gpac/gpac/issues/549
https://github.com/gpac/gpac/issues/235
https://github.com/gpac/gpac/issues/951
I found the discussions there interesting.
I have about 6 mp4 videos that have been encoded using FFmpeg. All have AVC and AAC. Frame rate mode Constant. Frame rate: 23.976 (24000/1001) FPS
I could use FFmpeg to concatenate, but with MP4Box, I should just be able to enter MP4Box -cat video_1.mp4 -cat video_2.mp4 -new concated.mp4. This looks nice and easy.
The problem surfaces with the program MediaInfo which provides easy access to technical and tag information about video and audio files. I have used this program for many years and find it invaluable.
Using MP4Box to concatenate my videos, the frame rate is changed to variable.
Frame rate mode : Variable
Frame rate : 23.976 (23976/1000) FPS
Minimum frame rate : 15.434 FPS
Maximum frame rate : 23.976 FPS
I have tried these option: -force-cat -add -nodrop -fps. But they do not keep the frame rate constant.
I have also notices the audio Bit rate mode changes from constant to Variable with a Maximum bit rate and Minimum bit rate.
Is there some way I can keep constant rates please?

You can set cover art like this
~~~
mp4box -itags cover=1.jpg 1.m4a
~~~
However none of these remove it
~~~
mp4box -itags cover= 1.m4a
mp4box -itags cover=0 1.m4a
mp4box -itags cover=NULL 1.m4a
~~~
this works, but it removes all tags
~~~

If a subtitle with `<i>` tag comes right after subtitle with `<font>` tag, then it (and all subsequent subtitles with `<i>` tag) will be displayed in color set by the `<font>` tag (i.e. from a previous subtitle) until a "clean" subtitle (without tags) is reached.
Simple example:
`1`
`00:00:05,000 --> 00:00:10,000`
`<font color="#ffff00">Text line 1</font>`
`2`
`00:00:12,000 --> 00:00:15,000`
`<i>Text line 2</i>`
`3`
`00:00:17,000 --> 00:00:20,000`
`<i>Text line 3</i>`
`4`
`00:00:22,000 --> 00:00:24,000`
`Text line 4`
In this example, `Text line 2` and `Text line 3` will be displayed in yellow color.
If you try to export that subtitle stream with srt convertion from the resulting mp4-file (MP4Box -srt 4 file.mp4), then the tags will be screwed up in the exported file.
MP4 file was made using `MP4Box GPAC version 0.7.2-DEV-rev415-g5c3781e7-master` official nightly build on `Ubuntu 16.04 LTS 64 bit`.
The file was tested in QuickTime Player on latest macOS High Sierra (version 10.13.) and MP4Client from the same build.

Hello.
Using this commit 6db050e9ba41c06e6e04335b3129df1105721b70 one is able to successfully cross-compile mp4box under ubuntu 17.10.1 with mingw64.
At and from commit 96b6df1df2d60f4e285cf1380eed4bf6e0021439 it fails with the error at the end of this log:

Hello guys,
I have pre-encoded videos using DashCast, and I am streaming them via MP4Client on Windows OS.
I disabled the CleanCache. and now I can receive them in the Temp. folder in C partition.
My question is that "is there any way to let the name on the Temp. folder become in an orderanry way; so instead of getting files such as gpac_cache_82ECE62E83D1E98E745DB7AA3FFFE3C71210626F.mp4, i simply get them as 1.mp4, 2.mp4... etc"?
I hope i can find an answer here for this issue.
Thanks a lot

Can I rename files in Temp. folder?

Ever since I updated to recent builds (or from Master), when I run MP4Box to get full info
ex:
mp4box -diso -std some_file.mp4 > mp4box_out.xml 2>&1
I am seeing a closing tag without an opening tag in the resulting XML:
</ISOBaseMediaFileTrace>
This seems to be a new bug that is causing us headaches. Any ideas?

Hi, I'm new to MP4box and I would appreciate any valuable tips that can help solve my problem.
Recently, I'm working on creating dash streams that has GOP alignment with source, which means all dash streams must have exact same IDR and IDR PTS as source (which is not transcoded to bear regular IDR interval). I was able to make all transcodings using ffmpeg to align with source, but after running mp4box, the dash files shows IDR and PTS misalignment, which I cannot figure out why.
For example, the source file dash_v4_passthrough.mp4 (also a dash file after mp4box) has IDR indexed 1:31:54:84:110:140:164:194:224:227:257
with PTS of IDR at
0, 1.2, 2.12, 3.226667, 4.306667, 5.506667, 6.46, 7.461667, 8.475, 8.628333, 9.828333
The transcoded video after ffmpeg passthrough_hq1_sd.mp4 has exactly the same IDR index and PTS as source. But, after I run mp4box command:
MP4Box -dash 2000 -profile dashavc264:onDemand -bs-switching no -rap -frag-rap -out manifest.mpd dash-demux-video.mp4
The output dash file dash_passthroughaligned.mp4 now has IDR indexed:
1:31:54:84:110:163:193:223:226:256 (you can see there is 1 IDR less)
with PTS of IDR at
0, 1.2, 2.12, 3.22, 4.346667, 6.386667, 7.415, 8.415, 8.588333, 9.821667 (PTS of IDR also changed)
Now, does MP4box support dash fragment that keeps IDR and timestamp as input? I assum -dash 2000 will try to find the closest IDR within 2s, but I don't know why it also changes IDR index and timestamp. Ideally, I want my dash output bearing the same IDR structure of mp4 input. Any idea? Thank you!

Hey, Is there any way to control the state of tile, namely displaying or undisplaying?
For example, I split 4k video into 3x3 tiles. And now, I want to make the first tile undisplayed.
Appreciate anyone's clues, thanks.

Hi,
How can we play 360 LIVE profile in OSMO4 on Android for HEVC tiling? I tried adding #360 at the end of URL but it is not working. I also searched in preferences and options but couldn't find anything. Although adding #360 at end of URL worked on UBUNTU.
Thanks for reporting your issue. Please make sure these boxes are checked before submitting your issue - thank you!
- [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 ...).

Hey, I wonder know which parts of code are used for rendering. Because I want to embed Oculus Rift into mp4client. In other words, i wonder know which part of code is used to render after decode media. Appreciate for anyone's help!
Should I try to write a new glsl code and use this command.
`MP4Client -opt Compositor:StereoType=SideBySide -Compositor:NumViews=2 -Compositor:InterleaverShader=/path/to/oculus.glsl $url`

I currently experience an issue with the MP4Client, when streaming a regular DASH video, with the following header of the MPD file:
`<MPD xmlns="urn:mpeg:dash:schema:mpd:2011" minBufferTime="PT2.500000S" type="static" mediaPresentationDuration="PT0H17M44.07S" profiles="urn:mpeg:dash:profile:isoff-live:2011">
`
when using the _GPAC_LEGACY_BUFFER_ADAPTATION_, I encounter the issue, that the player only switches to higher bitrates. Even when the buffer is about the be empty, it sticks with the highest representation.
So I had a look to the code and identified the place, where the switching is happening. It is implemented in media_tools/dash_client.c on line 2641. There we are supposed to switch down, if the buffer is below a certain threshold. We then set the _go_up_bitrate_ variable to false and continue with the function, _dash_do_rate_adaptation_legacy_rate_ on line 2517. Then we end up at the code, that says:
```
else {
/* go_up_bitrate is GF_FALSE */
/*try to switch to highest bitrate below available download rate*/
if (arep->bandwidth > new_rep->bandwidth) {
new_rep = arep;
new_index = k;
}
```
But apparently this is not working, as it should... Can it be that there is something wrong with the bandwidth measurement? We would like to go one below the current bandwidth, so I would assume something like: `arep->bandwidth <= rep->bandwidth` or why is it not behaving as it should?
Best
Remo

My environment:
ubuntu 16.04 LTS desktop x64
Question: How to enable openhevc when compiling gpac
this is my step:
Step one:
I download gpac source code from https://github.com/gpac/gpac and extra libs from http://download.tsi.telecom-paristech.fr/gpac/gpac_extra_libs.zip.
Step two:
I install ffmpeg and use the following command line
`sudo apt-get install zlib1g-dev xulrunner-1.9.2-dev libfreetype6-dev
libjpeg62-dev libpng12-dev libopenjpeg-dev libmad0-dev libfaad-dev
libogg-dev libvorbis-dev libtheora-dev liba52-0.7.4-dev libavcodec-dev
libavformat-dev libavutil-dev libswscale-dev libxv-dev x11proto-video-dev
libgl1-mesa-dev x11proto-gl-dev linux-sound-base libxvidcore-dev
libwxbase2.8-dev libwxgtk2.8-dev wx2.8-headers libssl-dev libjack-dev
libasound2-dev libpulse-dev libsdl1.2-dev dvb-apps`
Step three:
Because my os is x64. Hence, I choose to download last version of openhevc from https://github.com/OpenHEVC/openHEVC. And then I compile it and copy libLibOpenHevcWrapper.a to extra_libs/lib/gcc.
Step four:
go to the gpac-master fold and then use `./configure`
the response is :

Hi, could i ask some help to confirm that this MPD is write correct for two adaption sets thats works in live streaming?
Cause at the moment im unable to simulate lower bandwidth: i tried with chrome/consolle/performance but without result, this is what i read from the console:
`[3945283] AbrController (video) stay on 1/1 (buffer: 24.141) `
1/1 make me think that is not work properly.

I am looking for some help with above. My usecase is described below -
I am using ffmpeg to produce live hls segments. These hls segments are generated sequentially for live and contain presentation time and other metadata inside. I want to also support MPEG DASH and I was looking for a way to convert these HLS segments to fragmented MP4. I was looking for a way to do this using MP4Box if possible.
I am planning to run MP4Box command line every time there is a new HLS segment created for a particular bitrate. This would allow me to generate corresponding MP4 fragment with necessary metadata. I am planning to build my own tool to generate manifest and hence would not need the manifest generation support. I need following from MP4Box -
1. A command to generate MP4 while preserving Live timestamps etc. I used below but, it doesn't generate live related boxes e.g. sidx is missing. Also resultant file has green bars in it.
> MP4Box -add in.ts out.mp4 -dash-ctx DASH.txt -profile live -segment-ext mp4
2. A command to split this into initialization fragment and content fragment.
In addition, I did try to do this with ffmpeg as well. It produces a valid video clip but, misses out on Live metadata.
/usr/local/bin/ffmpeg -y -i in.ts -codec copy -loglevel verbose -debug_ts -copyts -bsf:a aac_adtstoasc -movflags empty_moov+omit_tfhd_offset+frag_keyframe+default_base_moof out.mp4
Any help would be appreciated.

I am try to move the 'moov' header from the end to front with command 'MP4Box -inter 500 my.mp4' after I have created a new mp4 files with ffmpeg v2.8. I found that there are 4 bytes redundant data in 'avcC' box after the operation when I was trying to check the output files.
I thought that might be some thing wrong here although that the output could be played properly.

I encode a 360 video at N tiles by kvazaar encoder and each tile is encoded independently. And at the same time, I encode it at M bitrate levels for adaptive bitrate control. I use mp4box to generate dashed content. I want to add a new adaptive algorithm which only play tiles in field of vision based on gpac framework. My question is how to set representations in FOV downloaded.
And then after finishing adaptive algorithm and compiling, I wonder know how to use command line to enable algorithm.

Hello, I would like to ask about a strange behavior that I found reading the terminal while MP4Box processed a video for the live.
Some videos react to the -segdur in an inflexible way: the next segment always is scheduled after 16000ms in my case.
Other videos once finished when they have to start again in loop have a delay even if without apparent errors: instead of getting the next segment 16000ms after the last, I can notice a delay that always occurs at the end/start of the video and is added from time to time.
I tried to change the duration of the video to always get even seconds (aligned with the gop), but the problem persists, I would like to know which differences in the videos trigger these reactions and if it can be a problem. below my commands:
`ffmpeg -y -i in.mp4 -c:a copy -c:v libx264 -x264opts 'keyint=48:min-keyint=48:no-scenecut' -r 24 -b:v 1500k -maxrate 1500k -bufsize 1000k -vf "scale=-1:800" out.mp4
`
`MP4Box -dash-live 8000 -subdur 16000 -profile dashavc264:live -mpd-refresh 240.0 -bs-switching no -time-shift 80 -min-buffer 4000 -insert-utc -out manifest.mpd out.mp4#video out.mp4#audio
`
could i also ask for a possible correction of the commands, do they seem correct for a live stream to dash.js?
Thanks a lot,
Dan

- [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/
Hello 😃
Apologies if this is a known (recent) bug or a change by design 😕
Some years ago I wrote (actually I forked the script from someone else, then adapted it to MP4Box) the following Windows batch script:
```bat
ECHO OFF
REM MP4Box Prompt
REM Open a command prompt to run MP4Box
TITLE MP4Box Prompt
IF NOT EXIST mp4box.exe (
CLS
ECHO mp4box.exe could not be found.
GOTO:error
)
PROMPT $G
CLS
mp4box -version
SET PATH=%PATH%
ECHO.
ECHO For help run: mp4box -h
ECHO.
CMD /F:ON /Q /K
GOTO:EOF
:error
ECHO.
ECHO Press any key to exit.
PAUSE >nul
GOTO:EOF
```
I have saved that script as file `mp4box-prompt.bat`
My primary OS is Windows 7 SP1 32-bit (but I also occasionally use Windows Vista SP2 32-bit).
In May 2017, I had compiled myself the following MP4Box static build:
```
MP4Box - GPAC version 0.7.2-DEV-rev67-g975c0eb7b-ab-suite
GPAC Copyright (c) Telecom ParisTech 2000-2012
GPAC Configuration: --host=i686-w64-mingw32 --build=i686-w64-mingw32 --target=i6
86-w64-mingw32 --prefix=/local32 --disable-shared --enable-static --static-mp4bo
x
Features: GPAC_DISABLE_3D
```
When files `mp4box.exe` and `mp4box-prompt.bat` are in the same directory, running the batch file will produce the following output in a command prompt window:
```
MP4Box - GPAC version 0.7.2-DEV-rev67-g975c0eb7b-ab-suite
GPAC Copyright (c) Telecom ParisTech 2000-2012

86-w64-mingw32 --prefix=/local32 --disable-shared --enable-static --static-mp4bo
x
Features: GPAC_DISABLE_3D
For help run: mp4box -h
>
```
I recently acquired the following static build of MP4Box (presumably also built by [media-autobuild_suite](https://github.com/jb-alvarado/media-autobuild_suite)):
```
MP4Box - GPAC version 0.7.2-DEV-rev357-g7115eeb89-ab-suite
GPAC Copyright (c) Telecom ParisTech 2000-2012
GPAC Configuration: --host=i686-w64-mingw32 --build=i686-w64-mingw32 --target=i6
86-w64-mingw32 --prefix=/local32 --disable-shared --enable-static --static-mp4bo
x
Features: GPAC_DISABLE_3D
```
This build works OK if I open manually a command prompt window and CD to its location on disk (this is how I copied its `-version` info), HOWEVER, **if I run the posted batch file from the same directory, a cmd window flashes for fractions of a second (and I can tell it's not empty) and then instantly vanishes**...
Prior to posting, I repeated that test with latest win32 GPAC nightly build (**gpac-0.7.2-DEV-rev367-ga7a79f45-master-win32.exe** at this time) and _I could reproduce_; FYI, you need files `mp4box.exe`, `js.dll`, `libeay32.dll`, `ssleay32.dll` and `mp4box-prompt.bat` _in the same directory_!
Any insight will be highly appreciated (as is the app itself ! ㊗️ ) Ideally, I'd like to keep using my custom batch file with mp4box.exe - do I need to change some syntax by adding some newly added switch?
Thanks in advance...
Regards.

Hello, I'm using MP4Box inside a web server to generate livestream.
I'm having trouble with the timeline after an hour since it started
After ffmpeg specific encoding i use:
`MP4Box -dash-live 4000 -rap -frag-rap -profile dashavc264:live -subdur 4000 -bs-switching no -time-shift 20 -out manifest.mpd video.mp4#video video.mp4#audio`
All work fine on all common browsers, except a warning about the process is sometime too late, but it don't seems to create any issue to dash.js that work fine:
```

```
Do you now how can i make the streaming unstoppable?
I run my tests on a macbook 13 of 2014 so I fear it may be the fault of the hardware, could confirm?
Thanks,

Hi,
Is it possible to add some custom atom in the header of a MP4 video file?
Would the library "MP4Box" be useful for this purpose?
I need to add the terms "beam" and "loop" in the header of MP4 files before the "moov" atom.
More information can be found here :
https://stackoverflow.com/questions/44893316/whatsapp-video-as-gif-sharing-on-android-programatically
I do not want to edit the headers via too much calculations, as the answer suggests. Is there a simple way to add the atom "loop" to any MP4 files?
How does one go about using your library, and adding a custom atom to any MP4 file?
Use Case :-
WhatsApp does a smart thing. Their animated GIFs are actually MP4 files (which contain this atom "loop"), and the MP4 files which it wants to treat as videos in their UI, they do not add that "loop" atom. We wish to do something similar.
Any help would be truly appreciated!

Hi everyone, I'm learning how to work with mpeg-dash. Most of my gaps are in the encoding,
May i ask if my process and encoding is correct? I have some question about GOP
- First i use check the frame rate with "ffmpeg -i leg.mp4", in this case 23.98 fps
```
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'I Am Legend - Trailer.mp4':
Metadata:
major_brand : isom
minor_version : 1
compatible_brands: isom
creation_time : 2007-11-27T01:10:05.000000Z
title : I Am Legend - Trailer
artist : Warner Bros.
date : 2007
genre : Science-Fiction
encoder : MeGUI
Duration: 00:02:03.24, start: 0.000000, bitrate: 8145 kb/s
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x816 [SAR 1:1 DAR 40:17], 7887 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 47.95 tbc (default)

handler_name : GPAC ISO Video Handler
Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, 5.1, fltp, 258 kb/s (default)
Metadata:
creation_time : 2007-11-27T01:10:11.000000Z

```
- Second i use ffmpeg as streemroot teach with a gop of 24 like below:
`ffmpeg -y -i leg.mp4 -c:a aac -ac 6 -ab 128k -c:v libx264 -x264opts 'keyint=24:min-keyint=24:no-scenecut' -b:v 1500k -maxrate 1500k -bufsize 1000k -vf "scale=-1:720" leggop.mp4`
If i use -ac 6 i maintain 5.1 channels?
Unfortunately at the moment I'm unable to install libfdk_aac, may i ask if there is notable differences?
- Third i run MP4Box:
`sudo MP4Box -dash-live 1000 -frag 1000 -profile live -subdur 1000 -mpd-refresh 1000 -time-shift 9 -bs-switching no -segment-name output-seg -out manifest.mpd leggop.mp4#video`
May i ask if there are some timing problem between 23.98 and 24 fps GOP?
Why i can not resolve demultiplexing like: `leggop.mp4#video leggop.mp4#audio`
ERROR:
```
[DASH] Segment output-seg2.m4s (Number #2): drift between MPD timeline and tfdt exceeds 50% of segment duraion (MPD time minus TFDT 1.000000 secs) - bitstream will not be compliant, try using segment template or reencode
Error while DASH-ing file: Bad Parameter
```
Thanks a lot

Hi, i try to obtain a playlist that is constantly played in loop for pseudo live use with -dash-live option.
How can i modify it to obtain a sequence of videos, and after the last loop again on the first to the infinite until q is press?
COMMAND LINE
sudo MP4Box -dash-live 1000 -frag 1000 -profile live -subdur 1000 -mpd-refresh 1000 -time-shift 3 -bs-switching merge -segment-name output-seg -out manifest.mpd simp.mp4
May i need the same resolution between the playlist files? Or there are some requests for conformity between the files?
Thanks!

Hi there, I'm trying to get a pseudo live with mp4box and visualise it with dash.js inside apache or mamp, my os is sierra.
For my test i use a video already encoded of Simpsons http://www.h264info.com/clips.html,
cause i understand that the encode by ffmpeg is necessary only for multi bitrate purpose and for the moment i don't need it.
Osmo work fine, can read the manifest fast and well
Dash.js example works fine with theirs manifest link inside the html, but it can't works with my manifest. So i understand that Dash.js work.
COMMAND LINE:
sudo MP4Box -dash-live 1000 -frag 1000 -profile live -subdur 1000 -mpd-refresh 1000 -time-shift 16 -bs-switching no -segment-name output-seg -out manifest.mpd video_test.mp4
I use sudo cause I'm using osx but i believe that don't create any issue.
I try different browser, the dashifk conformance page.
I can't understand why on Mamp or Apache, the page can't visualise the manifest I'm generating for pseudo live use.
Where I'm wrong?
Could you help me?
Thanks!
Gianmaria

Hi there,I'm studying how to get a "pseudo live" on osx, I take this opportunity to say that the tools of gpac are rich in documentation, also suitable for those who are not a professionist like me.
COMMAND LINE:
sudo MP4Box -dash-live 1000 -frag 16000 -profile live -subdur 1000 -mpd-refresh 1000 -time-shift 3000 video_test.mp4
Give me a good result on Osmo, mi first stable result, but for the moment I'm unable to run it on dash.js.

First thing to improve, I would like to understand how to delete segments too old, in this case a video of two mb after a few minutes begins to weigh over 200 mb.
Could you help me about?
Thanks

I thought there was some chance that mp4box outputs MOVs as well, so I did a test: `mp4box -add in.mp4 -new out.mov`. To my surprise, this "worked" i.e. output file was created and no error or warning was thrown.
Unsurprisingly, output file is ISOBMFF but the lack of exception on the extension may confuse some users who try something similar. Suggest a basic check be added.
Thanks,
Gyan

I made h265 file(by x265) and imported the raw h265 to mp4box
and exported nhml file
and imported nhml file without any change
> mp4box -new -add video.h265 video.mp4
> mp4box -nhml 1:full video.mp4
> mp4box -add video_track1.nhml video_nhml.mp4
at this case, I got a strange mp4 file which takes a lot time when jumping. (like no key frame)
the original video.mp4 can jump correctly.
And next, I tried by nhnt(mp4box -nhnt 1 video.mp4 & import)
at this case, I got jumpable file.
I looked for the differences between the nhml and nhnt files.
I'm not sure, but in the nhml file, the almost all "isRAP" was "no"(except 1st one) and with nhnt file looks the some RAP bit are "yes".
with h264 files, this problem doesn't occur.
So, I think there is something wrong in exporting nhml with h265 file.
Does one know about this problem?
|
with HEVC/H265 files, mp4box -nhml may output wrong "isRAP".

720.mpd - Manifest after dashing
mp4box_enc_video_sintel_trailer-720p_dashinit.mp4 - dashed ondemand file
I also tried with `MP4Box - GPAC version 0.7.2-DEV-rev358-g433fbcc35-master` and got the same error.
With v0.6.1 - I don't get `Unknown box type` warning but the end result is same. No playback in edge. If I remember correctly the error code is different and I am happy to provide more details if you need it.
Any help is appreciated. Thanks!

I have a functional mkv container with HEVC video I'm trying to mux into a m4v container. I use ffmpeg to export the hevc stream. This stream can be viewed in media players by itself, letting me know it is still valid. I then use the following to mux the stream into a m4v container.

The m4v file generated can be opened in various media players but no video stream is shown. If I mux in an audio stream, usually this will play by itself but still without video. **I have successfully muxed HEVC into m4v containers with BT.709 color space, but it seems to fail consistently with streams in higher color spaces (e.g., BT.2020).**
Not sure if this is a bug in mp4box or deficiency of the m4v container format.

I installed my gpac package by compiling the source from the tag v0.7.0. I'm currently using Ubuntu 16.04.3.
I keep getting segmentation fault when I run MP4Client. Below is the command I run:
`MP4Client -lf ~/log_file_dec_27_2017_23_33.log -logs all@info http://www-itec.uni-klu.ac.at/ftp/datasets/DASHDataset2014/ElephantsDream/15sec/ElephantsDream_15s_onDemand_2014_05_09.mpd`
I have also attached the log file I generated. Near the bottom end of the log file, it says:
> [iso file] Incomplete file while reading for dump - aborting parsing
Is this what's causing the segmentation fault? If so, how do I fix it?

I am trying to concatenate the following two files:
- https://www.dropbox.com/s/oszkou1mpdek89w/part1.combined.mp4?dl=0
- https://www.dropbox.com/s/pgsltpvnv4bkb0s/part2.combined.mp4?dl=0
I use the command: `MP4Box -cat part1.combined.mp4 -cat part2.combined.mp4 out.mp4`. (I tried other variants, such as `-add` for the first file, `-force-cat` and `-keep-all`)
The resulting file does not have voice for the second part. Both parts are screen captures created using the same settings to `recordmydesktop`. The mp3 audio tracks were recorded separately, but I made sure to make them suitable length (namely, I used the `-info` option to see the length of the video track and then exported a selection of that length from the audio track using `audacity`). The video and the audio tracks were merged by using `MP4Box -new -add part1.video.mp4 -add part1.audio.mp3 part1.combined.mp4`.
The output of MP4Box for concatenating the two parts:
> Appending file part1.mp4
> No suitable destination track found - creating new one (type vide)
> No suitable destination track found - creating new one (type soun)
> Appending file part2.mp4
> No suitable destination track found - creating new one (type soun)
I saw this issue discussed, but have not seen a solution that would help in my case.
