Maybe it would be useful to double check the file with
a different tool/decoder, just to make sure that the track
is reasonably decodable at all? If the file is too damaged
so that proper decoding isn't really possible, I'd honestly
not waste any time to work around the damage. But if
other tools/decoders can decode this sample just fine, then
so should the libav decoder.
