Hi all,

I am trying to find how to detect exactly the distortions in a video file.
I use this command line for analyzing a short video with some distortions:
*> ffmpeg -loglevel verbose -i
$HOME/Téléchargements/Video-file/Foreman/f_ge_0.02_0.9_1.mp4 -vf showinfo
-f null - &> LOG.txt*

When i analyze the logfile, i could read, some errors like:
*[h264 @ 0x93a25c0] error while decoding MB 13 15, bytestream (-11)
[h264 @ 0x93a25c0] concealing 88 DC, 88 AC, 88 MV errors

*What does it mean ? I want to undestand these numbers displayed.
Thank you.

O. Stiti
