Linux/AM5728: GStreamer C/C++ Example Code

Marc48067
Expert 2000 points
Part Number: AM5728
Other Parts Discussed in Thread: TMDSEVM572X

Tool/software: Linux

Hello,

I am using the AM572x Evaboard and installed the linux SDK. 

We want to grab the video via VIP (AM57xx EVM Camera Board) and generate a H.264 network stream, display video via HDMI and LCD and record on filesystem. If possible all in parallel. We don't need GUI interfaces, so no need for QT.

Do you have an example for the gstreamer command line tools for the above tasks?

In folder ti-processor-sdk-linux-am57xx-evm-03.01.00.06/example-applications I couldn't find demo C/C++ code which shows how to use gstreamer in own applications. Where can I find this?

Thanks in advance

Marc

    Hi Marc,

    you can find example videopipes for AM572x here:

    developer.ridgerun.com/.../index.php

    If you want to use them in C/C++ code you can check for some directions here:

    stackoverflow.com/.../gstreamer-convert-command-line-gst-launch-to-c-code

    Check TI wiki page:

    http://processors.wiki.ti.com/index.php/Processor_Training:_Multimedia

     If my understanding is correct you want to split the pipeline on "3 branches" : one for capture->display, one for capture encode save in file and one for capture encode stream via network.

    If yes, you could try to use a gstreamer's tee element.  The tee element split data to multiple pads. I would recommend to try with 2xtee elements one connected before the encoder to split the data to display and one tee element after the muxer to split the data to save in file and network streaming.

    There is no such demo in PSDK.

    You could check these links :

    https://gstreamer.freedesktop.org/documentation/application-development/basics/helloworld.html

    gstreamer.freedesktop.org/.../manual.pdf

    Hope this helps.

    Thanks for the information

    I have 2 additional questions:

    1. What is the maximum input resolution for the TMDSEVM572x Camera Module which can be used in gstreamer?
    2. Is there a tool where I can measure the system performance (CPU load,...) while running gstreamer via command line?

    Thanks

    Hello,

    I was able to record and display camera video on HDMI via gstreamer. But until now I couldn't encode the video (H.264 or MPEG4) and generate a network stream.

    Hello,

    Please check the wiki page in my previous post.

    Here is example pipeline for capture and encode and display and save in file (mp4) in parallel.
    gst-launch-1.0 -e v4l2src device=/dev/video1 num-buffers=1000 io-mode=4 ! 'video/x-raw, \
    format=(string)YUY2, width=(int)1280, height=(int)720, framerate=(fraction)30/1' ! vpe num-input-buffers=8 ! tee name=t ! \
    queue ! ducatimpeg4enc bitrate=4000 ! queue ! mpeg4videoparse ! qtmux ! filesink location=x.mp4 t. ! queue ! kmssink
    Here is also examples for network streaming:

    gst-launch-1.0 -v v4l2src device="/dev/video1" ! 'video/x-raw,format=(string)YUY2,width=1280,height=720,framerate=(fraction)30/1' ! videoconvert ! ducatih264enc ! h264parse ! queue ! mpegtsmux ! udpsink host=192.168.0.xxx port=xxxx

    gst-launch-1.0 -v v4l2src device="/dev/video1" ! 'video/x-raw,format=(string)YUY2,width=1280,height=720,framerate=(fraction)30/1' ! vpe ! ducatih264enc ! h264parse ! queue ! mpegtsmux ! udpsink host=192.168.0.xxx port=xxxx

    gst-launch-1.0 -v -e videotestsrc ! queue ! 'video/x-raw,width=1280,height=720,framerate=30/1' ! queue ! ducatih264enc ! queue ! h264parse ! queue ! rtph264pay ! queue ! udpsink host=192.168.0.xxx port=xxxx sync=false

    Regarding the CPU load you could try 'top -d 1' command.

    Thanks for the information Margarita!

    I built up a pipeline which does HDMI output, encode and save to file and stream via network.

    gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 ! 'video/x-raw,format=(string)YUY2,width=800,height=600,framerate=(fraction)30/1' ! vpe ! 'video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080' ! tee name=t ! queue ! ducatimpeg4enc ! mpeg4videoparse ! mpegtsmux ! tee name=q ! queue ! filesink location=/home/root/video.mp4 q. ! queue ! udpsink host=192.168.3.147 port=5555 sync=false t. ! queue ! kmssink scale=false -v -e

    The pipeline runs and from time to time there are critical errors. And in the end, the pipeline aborts.

    Before the pipeline aborts, HDMI output, network streaming and recording work fine.

    What could be the reason for that memory error?

    Thank for your help!

    Hello,

    The pipeline seems fine.

    You received this error when the pipeline is running or sometimes when you execute it you see this error?

    Hello,

    the pipeline can be started and runs correctly. While it is running this error occurs from time to time, but the pipeline still runs. And lastly there are many errors at once and the pipeline aborts.

    Filesystem and kernel are on sd card. Video file is also stored on sd card.

    What does this error mean? It seems to be critical.

    Hello,

    I have not seen such an error.
    You could check gstfdmemory.c for it.
    Could you set udpsink's  and kmssink's sync property to true also?

    Hello Margarita,

    setting sync of kmssink and udpsink to true doesn't fix the problem. Below you can see a detailed output. The error at the end is little bit different then one shown above. It seems to be a v4l2 problem?!

    If you have an AM572x Evaboard with camera module, you can just execute the gst-launch line shown below. Perhaps you can reproduce the problem.

    gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 ! 'video/x-raw,format=(string)YUY2,width=800,height=600,framerate=(fraction)30/1' ! vpe !

    Hello,

    I am sorry I can not set your use case.
    Do you observe this behavior without the "streaming branch"(only save in file and display)?

    Hello,

    when I remove the streaming branch (only save in file and display), the error also occurs. When I remove the save to file branch (only streaming and display) it seems to work fine.

    Hello,

    Could you check is this working?
    gst-launch-1.0 -e v4l2src device=/dev/video1  io-mode=4 ! 'video/x-raw, \
    format=(string)YUY2, width=(int)1280, height=(int)720, framerate=(fraction)30/1' ! vpe num-input-buffers=8 ! tee name=t ! \
    queue ! ducatimpeg4enc bitrate=4000 ! queue ! mpeg4videoparse ! qtmux ! filesink location=x.mp4 t. ! queue ! kmssink

    Hello,
    I checked the following:

    gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 ! 'video/x-raw,format=(string)YUY2,width=800,height=600,framerate=(fraction)30/1' ! vpe num-input-buffers=8 ! 'video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080' ! tee name=t ! queue ! ducatimpeg4enc ! mpeg4videoparse ! tee name=q ! queue ! qtmux ! filesink location=/home/root/video.mp4 q. ! queue ! mpegtsmux ! udpsink host=192.168.3.147 port=5555 sync=false t. ! queue ! kmssink scale=false -v -e

    It works fine. It was running for 1 hour without problems. It is important to use 2 different muxers for streaming and save to file. It is also important to use several input buffers for the vpe. Otherwise it doesn't work.

    Thanks for your support
