| Ticket Name: Gstreamer not working in GLSDK 7.03 | |
| Query Text: | |
| Other Parts Discussed in Thread: TDA2 Hi, Can anybody please guide me in making gstreamer work on GLSDK 7.03? I am new to this and I feel some difficulties. I use this command "gst-launch-1.0 filesrc location=sample.mpg ! mpegtsdemux name=dmux dmux. ! queue ! h264parse ! ducatih264dec ! kmssink connector=12 dmux. ! queue ! faad ! alsasink" where sample.mpg is the input file. But I get this error "WARNING: erroneous pipeline: no element "mpegtsdemux" ". 1. How should I check if any sample video is working fine with my J6 EVM Board (GLSDK 7.03)? Kindly help me out in this issue. 2. Please let me know, what kind of Video formats are supported in GLSDK v7.03. 3. Supported Playback Application in GLSDK Data Sheet mentions that the Gstreamer version is 1.2. But I see that "gst" files in the installed files (GLSDK 7.03) are with version name (v1.0). Please clarify the version of the GStreamer for GLSDK 7.03. Does it require any downloading of Libraries ?? Thanks in Advance, Shylesh S. | |

| Hi Shylesh, Can you try with playbin first? gst-launch-1.0 playbin uri=file:///usr/share/sample.mpg video-sink=kmssink With explicit pipeline, try with qtdemux instead of mpeggstdemux | |
| Hello Ramprasad, Thanks a lot for your reply. When I tried with the playbin, with the following command, "gst-launch-1.0 playbin uri=file:///usr/share/sample.mpg video-sink=kmssink" I get only the Audio working. But my video isn't playing. I get this message in my terminal: Setting pipeline to PAUSED ... | |

| New clock: GstAudioSinkClock When I tried with the explicit pipeline, using the following command "gst-launch-1.0 location=sample.mpg typefind=true ! qtdemux name=demux demux.video_00 ! queue ! mpegvideoparse ! decodebin ! kmssink demux.audio_00 ! queue ! faad ! alsasink" I get the following error. ERROR: pipeline could not be constructed: Unrecoverable syntax error while parsing pipeline location=/opt/work/sample.mpg And also, please let me know whether I have to download any library files and cross compile them, so that my Application code works. Thanks in advance, Shylesh S | |
| Hello, You could check this user guide: processors.wiki.ti.com/.../DRA7xx_GLSDK_Software_Developers_Guide Could you attach the full log by adding --gst-debug=3. Could you try in location=sample.mpg property to add the full path to the file? Could you try to play the video file without the audio part? Let us know the result. BR Margarita | |
| Hello Margarita, Thanks for the support. I am new to GStreamer. So, Please guide me over this issue. Could you please tell me any video file source which will work with GLSDK 7.03 (GStreamer v1.2). Because, I keep testing with my same sample.mpg file. I have added the responses of the questions you asked in your last reply. 1. When I add “--gst-debug=3”, I get the below ERROR. 0:00:00.044078274 1760 0xb3380 WARN default ./grammar.y:902:priv_gst_parse_yyerror: Error during parsing: syntax error, unexpected ASSIGNMENT, expecting LINK 0:00:00.044245170 1760 0xb3380 ERROR GST_PIPELINE ./grammar.y:942:priv_gst_parse_launch: Unrecoverable syntax error while parsing pipeline location=sample.mpg typefind=true ! qtdemux name=demux demux.video_00 ! queue ! mpegvid | |

| Hello, Could you try : gst-launch videotestsrc ! 'video/x-raw-yuv,width=1280,height=720' ! kmssink The difference with the previous pipeline is in the caps video/x-raw-yuv . Please change the resolution according you display. Are you trying to play it on HDMI? BR Margarita | |
| Hi Margarita, You've mentioned "yuv" but the old pipeline had "YUY2"? Which one to use? And, yes I use HDMI to play this. The same HDMI display works in GLSDK 6.04 booted SD Card. The working of it is already checked. But I find no video being played with this GLSDK 7.03 (GStreamer v1.2). Response of this pipeline is, (gst-launch-1.0:1748): GStreamer-WARNING **: 0.10-style raw video caps are being created.

| Hi Margarita, I did go through the threads that you sent. Today I did search for video sinks through gst-inspect-1.0 | grep "video sink". I happened to see one (fbdevsink). Then, I tried this pipeline. And saw that Audio worked perfectly. Video also played. But, with lots of glitches and very slow. gst-launch-1.0 playbin uri=file:///opt/work/sample.mpg video-sink= fbdevsink audio-sink=alsasink I do not know the reason why this Glitches occur. Kindly help me. I then tried to use this sink with the following pipeline. gst-launch-1.0 filesrc location=sample.mpg ! mpegpsdemux name=dmux dmux. ! queue ! mpeg4videoparse ! ducatimpeg4dec ! fbdevsink dmux. ! queue ! faad ! alsasink But, I get errors saying that the decoder, parser, and sink in various combinations don't link eachother. Please guide me through this. Thanks a lot, Shylesh S. | |

| I get continuous prints like this when I use that pipeline. Kindly help!

Thanks & Regards, Shylesh S | |
| Hello, fbdevsink is using framebuffer (linux framebuffer). Could you grep for 'sink' or try to connect autovideosink in the pipeline? Autovideosink is a video sink that automatically detects an appropriate video sink to use. BR Margarita | |
| Hello Margarita, These are the video sinks that are available. fbdevsink, waylandsink, autovideosink, kmssink, intervideosink, v4l2sink, autovideosink. I actually tried all of them. Even, autovideosink doesn't work out. I just see my pipeline getting struck with the PREROLLING State. It's not getting Prerolled. Kindly help me out. Regards, Shylesh. | |
| Hello, Could you try to run Viddec3test demo. The demo currently runs on the kms display. Here you could check for more information: processors.wiki.ti.com/.../DRA7xx_GLSDK_Software_Developers_Guide If this demo is working could you try with kmssink but add property kmssink connector=xx. BR Margarita | |
| Hi Margarita, I had already checked the viddec3test demo. It didn't workout. "viddec3test -s 4:1360*768 sample.mpg --fps 30" These were the log when I run the about line: root@dra7xx-evm:/opt/work# viddec3test -s 4:1360*768 sample.mpg --fps 30 0x1c070: Opening Display..

Thanks! Shylesh S. | |
| Hello, What about viddec3test -s 12:1360*768 sample.mpg --fps 30 is it working? Are you using the default GLSDK or you made some changes? Are you using EVM or it is custom board? Did you try these pipelines: gst-launch -v filesrc location=input.mpg ! mpegtsdemux ! queue ! h264parse ! ducatih264dec ! kmssink connector=12 filesrc location=input.mpg ! mpegtsdemux name=dmux dmux. ! queue ! h264parse ! ducatih264dec ! kmssink connector=12 dmux. ! queue ! faad ! alsasink BR Margarita | |
| Hello Margarita, None of these pipelines are working. When I use 4 instead of 12 in "viddec3test -s 12:1360*768 sample.mpg --fps 30", I get no errors. But my video is not getting played. Yes, I do use the default GLSDK only, and I didn't make any changes. I use EVM board only. mpegtsdemux plugin is not available in GLSDK 7.03. Only mpegpsdemux, tsdemux are available. But, the video is not working in any of the pipelines. BR Shylesh S | |
| Hello, Could you try with elementary stream, h264 for example(not in container like ts)? In this case you will not need a demuxer. BR Margarita | |
| You want me to change my source file to a .h264 format? Can I convert my video (.mpg) to .h264 online and use it? BR Shylesh S | |
| Hello, You could try h264 elementary streamer or mpeg too. You could use ffmpeg on PC like : ffmpeg -i input.h264 -vcodec copy out.mp4 This example h264->mp4 BR Margarita | |
| Hello, I have tried with h264 file also, by using " ffmpeg -i input.h264 -vcodec copy out.mp4" The output file is recognized as h264 video file. But it doesn't play.

| I experienced that same problems with GLSDK 7 on a TDA2 board. The solution was to specify the connector ID of the active video port as an attribute to the kmssink filter, as follows: > gst-launch-1.0 -v filesrc location=$HOME/tftp/atest2.mp4 ! qtdemux ! h264parse ! ducatih264dec ! vpe ! kmssink connector=16 I could not find any mention of needing to specify the connector in the examples provided in the TI documentation. It would be very helpful if the docs were update to include it. HTH, Eric G | |
| Hi Eric, Thank you very much for your help. My video is perfectly working now. I had misinterpreted about the connector ID. I had previously checked the Connector ID, but I didn't use 16. Anyways, It's fine now!! Thanks a lot. And, Margarita... You've been helping me since last month. Thanks a lot. Thanks a lot. Best Regards, Shylesh S | |
