Comment (by denial):
If I understand correctly, what happens is that the MOV demuxer forgets to
set the headers_read flag for the fragment that has already been parsed by
mov_read_header. When av_seek_frame is called, mov_switch_root decides to
parse the headers again, resulting in mov_read_trun appending the values
for the first fragment a second time to the ctts array.
