Could you elaborate a bit on what you mean?

This patch mostly follows the pattern of the existing 'gmpd' track, however
it seems without adding logic to mov.c::mov_parse_stsd_data() the track is
not correctly identified. I just tested -c copy on a file with gpmd track
and it is lost during the copy (but tmcd track is not).
