EOF after decoding error

[Clément Bœsch]

The following sample ​http://samples.ffmpeg.org/Matroska/decode-error-stop.mkv makes ff* tools stop after approximately 1100 frames (or 45 seconds). The sample is 55 seconds long.

Steps to reproduce:

ffmpeg -i decode-error-stop.mkv -f null -
[...]
frame= 1097 fps=430 q=0.0 Lsize=       0kB time=00:00:45.75 bitrate=   0.0kbits/s    

or:

ffplay decode-error-stop.mkv

OTOH, MPlayer (with lavf demuxer and lavc decoder) is able to deal with it: just a few glitchy frames for 2-3 seconds, then playback is fine.

[Carl Eugen Hoyos]

Also reproducible with -an (and without -vn), MPlayer plays >50 seconds.

$ ffmpeg -i decode-error-stop.mkv -vn -f null -
