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/):
