OMX Decode Sample App on EZSDK

Steve Turley
Prodigy 60 points

I am attempting to run the video decode sample app in the EZSDK located here: /usr/share/ti/ti-omx/decode_a8host_debug.xv5T.  Below is the output I receive when running the application.  Afterward, the board is unresponsive and requires a power cycle.  The decode never completes.  I am able to decode the same file with FFmpeg and other tools without issue.  
root@dm816x-evm:/usr/share/ti/ti-omx# ./decode_a8host_debug.xv5T -w 1920 -h 1080
 -i /home/root/test.mpg -o /home/root/test.yuv -c mpeg2
input file: /home/root/test.mpg
width: 1920
height: 1080
output_file: /home/root/test.yuv
codec: mpeg2

    Steve,

    Most likely this is issue with the parsed frames. Component expect one frame(raw data) in one buffer. Parser in EZSDK can parse only elementary stream and does not parse PS/TS streams. Also elementary stream parser is primitive one, and may not parse all kinds of elementary stream. Could you please try parsing it offlline and provide the frames to decoder.

    Regards

    I was inputting an interlaced MPEG-2 file.  Deinterlacing offline using FFmpeg and then feeding that output into the decode sample made it work.
