Linux/AM5728: Multiple pipelines issue

Marka Reddy
Expert 1260 points
Part Number: AM5728


Tool/software: Linux

We are using am5728evm with linux sdk for capturing two streams of video data.One channel video is fed to vin3a form external dvi decoder. The another channel video is from usb webcam.Both the video streams are working fine individually whereas when combined we are facing issues.please see the debugs of gstreamer below.

root@am57xx-evm:~# gst-launch-1.0    v4l2src device=/dev/video1  !

    Hello,

    v4l2src1:streaming task paused, reason not-negotiated (-4)
    This error most of the cases means that format or framerate or resolution is wrong or not set.
    v4l2src1 is the second v4l2src element. Could you try to set format in the caps filter after the second v4l2src element.

    I would recommend you to replace videoconvert with vpe. Videoconvert element is a software element and you will observe high CPU. When the CPU load is higher frame drop could be observed. In the pipeline you have two of them.

    In additional, you could check this user guide for capture pipeline + vpe:

    Thank u for your inputs.
    can we replace videoconvert with VPE in both the streams? is multi-instances of VPE supported ?

    Hello,

    I see that the "first" capture provides YUY2 which is supported format on vpe's input/output.
    What is the format that "second" capture provides? I do not see it in the caps filter.

    Hello,

    What is the PSDK version that you are using?
    Are you using default bootargs?

    Hello,

    It seems like you are using PSDK 3.02 version.
    The latest PSDK version is 4.02.
    Please check the patch in the e2e link that I shared in my previous post.
    I also would recommend you to increase cma in bootargs.

    If you run the pipelines this way:


    gst-launch-1.0 -e --gst-debug=1 v4l2src device=/dev/video1 io-mode=4 ! 'video/x-raw,width=1024,height=768,framerate=30/1,format=YUY2' ! queue ! vpe num-input-buffers=8 ! queue ! ducatih264enc ! h264parse ! queue ! mp4mux ! filesink location=/home/root/1.mp4 &
    gst-launch-1.0 v4l2src device=/dev/video2 io-mode=4 ! 'video/x-raw,width=640,height=480,framerate=30/1,format=YUY2' ! queue ! vpe num-input-buffers=8 ! queue ! ducatih264enc ! h264parse ! queue ! mp4mux ! filesink location=/home/root/2.mp4 -e --gst-debug=1

    Is this working ?
