    Hello,
    /dev/video3 is the composite output.
    You shall down scale it to width=720 height=480.
    Add caps to the pipeline.

    Best Regards,
    Margarita

    Hello,

    Which EZSDK version you are using ? I see that the PSP version is old. The PSP version in EZSDK 5.05.02 is linux-2.6.37-psp04.04.00.01 it is checked with linux-2.6.37-psp04.04.00.02 as well.

    Best Regards,

    Hello,

    I used videotestsrc element. Could you try with it?
    I would recommend you again to move to the latest PSP version.

    Hi Margarita,
    I have changed projector i.e. pal out display unit and used the command
    gst-launch filesrc location=sample.mp4 ! qtdemux ! h264pa
    rse ! omx_h264dec ! omx_scaler ! 'video/x-raw-yuv, width=(int)720, height=(int)4
    80' !v4l2sink device=/dev/video3 userpointer=false min-queued-bufs=2

    but the video is getting played fast and stop for some time and start playing for some time and it stops abruptely without playing the entire video.

    when I am adding the "framerate=(fraction)30/1" it is not playing any thing.
    i.e.
    gst-launch filesrc location=sample.mp4 ! qtdemux ! h264pa
    rse ! omx_h264dec ! omx_scaler ! 'video/x-raw-yuv, width=(int)720, height=(int)4
    80,framerate=(fraction)25/1' !v4l2sink device=/dev/video3 userpointer=false min-queued-bufs=2

    Is this issue related to command?


    Thanks,
    Sudheer.

    Hello,

    Please set the sync property to the v4l2sink element.

    .... ! v4l2sink sync=true

    There is no point to set min-queued-bufs=2 since the default value is 2.


    Let me know the result.

    Hi Margarita,

                      This time I have changed the test video  i.e. Lip_Sync_Test_Markers.mp4 and resolution is 640X480.
     It was playing the video continuously but

    1 minute video it was playing 2 minutes,

    upper 70% of the video is displayed at the bottom and lower (30%) it is showing at the top and

    top video is distorted, bottom part of the video is better.

    gst command used is :

    gst-launch filesrc location=Lip_Sync_Test_Markers.mp4 ! qtdemux ! h264pa
    rse ! omx_h264dec ! omx_scaler ! 'video/x-raw-yuv, width=(int)720, height=(int)4
    80' !v4l2sink sync=true device=/dev/video3 userpointer=false min-queued-bufs=2

    Please help to resolve the issue.

    If possible can you attach the test video and the gst command used to play the video on pal out. I suspect the command or test video file I am using is having some issue.

    I have attached the test video which I have used. I have used the projector as the display unit.

    Thanks,

    Sudheer.
