The ffmpeg-users list is aimed at command-line users, you might try on the 
libav-user mailing list, it covers the libraries themselves

If you're calling the decoder directly, the various routines involved will 
all return a status. You may need to look into the behavior of the decoders 
in how they deal with corrupt data and whether they silently reconstruct a 
bad frame.

If you don't already have the ffmpeg source code, it would be a good idea to 
download that and look at the routines directly.
