Can you ask next, thank!

    Hi
    What is the vision-sdk version used? VISION_SDK v3.06 has support for video playback and display on waylandsink .
    What you are trying is an explicit pipeline and you need to know the format of the stream(h264, mpeg4 mpeg2, vc1 etc).
    Using playbin to playback will choose the correct parser and decoder.

    You can try
    gst-launch-1.0 playbin uri=file:///home/root/testvideo.mp4 video-sink=waylandsink

    or

    gst-play-1.0 --videosink waylandsink testvideo.mp4
    will work.
    This will choose hardware based decoder instead of software decoders(avdec).

    Thanks
