Are the following kludges for A_QUICKTIME and V_QUICKTIME ways to
accommodate old broken Matroska files that FFmpeg wrote in the past? I'm
asking because in normal cases, the fourcc in A_QUICKTIME and
V_QUICKTIME always starts at offset 4, without exception.
A_QUICKTIME:
if (ff_codec_get_id(ff_codec_movaudio_tags,
AV_RL32(track->codec_priv.data))) {
fourcc = AV_RL32(track->codec_priv.data);
codec_id = ff_codec_get_id(ff_codec_movaudio_tags, fourcc);
}
V_QUICKTIME:
if (ff_codec_get_id(ff_codec_movvideo_tags,
AV_RL32(track->codec_priv.data))) {
fourcc = AV_RL32(track->codec_priv.data);
codec_id = ff_codec_get_id(ff_codec_movvideo_tags, fourcc);
}
