Comment (by gjdfgh):
This also happens when seeking in the raw mpeg stream of commercial DVDs
(or at least one DVD). After printing this error, the decoder returns an
error. This is pretty bad for me, because I think this causes a slight
desync.
Looking at the code, I guess it simply fails with AAC_AC3_PARSE_ERROR_SYNC
internally. This error also happens when seeking with libdvdread or
libdvdnav (in which case seeking with libavformat is not involved at all).
This means it fails with the same error in both cases. I'm not sure what
to make out of it.
I uploaded a sample named "dvdsample" using
http://upload.ffmpeg.org/upload/, but I'm not really sure where the upload
form put it. (Maybe failed?)
