Comment (by wolfgangw):
Wrt lowres, Nicolas just let me know that he is merely removing the JPEG
2000-specific portions as lowres lives in avcodec.h. Thanks for the heads-
up, Nicolas.
Still, while using -lowres in something like
{{{
$ ffmpeg -lowres 3 -i j2c_10db24e2-0c6f-4ca2-9af7-a90a3685a0d6_.mxf
out.mkv
}}}
works as expected it is not working for my build of ffplay:

If something jumps out at you as to why my ffplay build seems borked I'd
appreciate a hint. I'll try and figure this out.
