Comment (by wader):

 This made me also noticed that ffmpeg currently does not verify the
 samples md5.

 Do you know if anyone has worked on adding that? think i might be
 interested in trying to add it. Had a quick look how the flac demuxer and
 decoder interact. I guess the md5 digest instance should be kept in
 FLACDecContext? but then should decoded samples be passed back to the
 demuxer or should the demuxer provide a md5 instance to the decoder? also
 verification would only work if no seeks were done.

 Maybe should ask in -devel list?
