Part Number: TMS320DM8168

Tool/software: Linux

Hi,

I wanted to play an interlaced video on a 1080P display using gstreamer. The video plays fine however the video is splited on the display. The pipeline used as below with the logs:

Kindly let me know if I am missing anything.

Thanks,

    Hello,

    You see it split because you are playing video with interlaced content and using omx_scaler. In this case you should use omx_mdeiscaler or omx_hdeiscaler instead of omx_scaler.

    Here is some examples:
    gst-launch -v filesrc location=x.h264 ! 'video/x-h264' ! queue ! h264parse ! omx_h264dec ! omx_mdeiscaler name=d d.src_00 ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! 'video/x-raw-yuv,width=(int)1920,height=(int)1080' ! gstperf ! omx_videosink d.src_01 ! fakesink silent=true sync=true


    gst-launch -v filesrc location=jstr.ts typefind=true ! mpegtsdemux ! queue ! mpegvideoparse ! omx_mpeg2dec ! omx_mdeiscaler name=d d.src_00 ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! gstperf ! omx_videosink d.src_01 ! fakesink silent=true sync=true

    Hope this helps.

    Do you have the overlay package ?

    Hello,

    You also could try:
    gst-launch -v filesrc location=xx.ts ! mpegtsdemux name=demux demux. ! queue ! mpegvideoparse ! omx_mpeg2dec ! omx_mdeiscaler framerate-divisor=2 gen-timestamps=false name=d d.src_00 ! omx_ctrl display-mode=OMX_DC_MODE_1080P_30 ! omx_videosink display-mode=OMX_DC_MODE_1080P_30 render-delay=500000000000
