Comment (by kieranjol):
Hi, another user just reported this issue to me. I checked with git master
and the initial sample - short.mxf - appears to decode correctly in both
ffmpeg and vlc, but jpeg2000_mxf_first_10mb is still showing half height.
I also decoded with libopenjpeg but only on ffmpeg 4.1.1 and that also
shows half height.
