    Decoding errors in AMF-DEM H.264 output

    alexh264

      Hi,

       

      I get corrupted H.264 stream from AMF-DEM example.

       

      FFMPEG error messages:

      [h264 @ 0000000006877a80] mb_type 3722 in I slice too large at 118 36

      [h264 @ 0000000006877a80] error while decoding MB 118 36

      [h264 @ 0000000006877a80] concealing 3722 DC, 3722 AC, 3722 MV errors in I frame

       

      I am attaching video file and complete ffmpeg output.

       

      The video is not playable in VLC either.

       

      Is there a player that can decode the produced stream ?

       

      Here is the output of H.264/AVC reference decoder (http://iphome.hhi.de/suehring/tml/):

      ldecod.exe

      Setting Default Parameters...

      Parsing Configfile decoder.cfg
