Thing is, I expect that DecodeBegin might actually expect the unmodified
extradata, i.e. without the endianness conversion we do when reading it
into the struct.
But for that I guess it would be necessary to test on big-endian, unless
someone already has.
And I'd appreciate it if you wouldn't CC me, I get enough mail without
getting everything twice, once in my folder for FFmpeg list mail and once
in my personal mail folder...
