[Libav-user] how to disable all concealing upon decoding audio/video stream

[qw]

Hi,
 
I use ffmpeg or ffmpeg lib to parse and decode mp4 and rmvb file, for some of which some concealment log will be shown on screen as follows:
 
[rv40 @ 0x16579e0] concealing 3440 DC, 3440 AC, 3440 MV errors in B frame
[rv40 @ 0x1804860] concealing 3440 DC, 3440 AC, 3440 MV errors in B frame
[rv40 @ 0x19b16e0] concealing 3440 DC, 3440 AC, 3440 MV errors in B frame
[rv40 @ 0x1a87e20] concealing 3440 DC, 3440 AC, 3440 MV errors in B frame
[rv40 @ 0x1b5e560] concealing 3440 DC, 3440 AC, 3440 MV errors in B frame

[h264 @ 0x1b910a0] concealing 60 DC, 60 AC, 60 MV errors in P frame
 
How to disable concealing and terminate decoding process when some bitstream error found?
 
Thanks!
 
B.R.
 
Andrew
