Comment (by wolfgangw):
Hm, it not only seems to accept X'Y'Z' but apparently it assumes X'Y'Z.
Which will make DCinema people happy (me happy :) and everyone else using
JPEG 2000 rather unhappy. The latter will get a color transform they did
not and would not ask for.
It is not at all safe to assume X'Y'Z' in JPEG 2000 in general. There
needs to be a switch.
Also with git HEAD -lowres n nags about highest possible value 0 and
Nicolas just posted a patch to suppress the option entirely in
libavcodec/jpeg2000dec.c. What's the reasoning behind this?
