Comment (by cehoyos):

 Replying to [comment:7 Aegwyn11]:
 > If I specify that I want -pix_fmt yuv422p10le on the output, it appears
 that the scaler is still invoked, but just converts from yuv422p10le to
 yuv422p10le,

 Did you test this? I am not 100% sure.

 > So is a better workaround to both specify -c:v libopenjpeg on the input
 side and to specify the correct -pix_fmt on the output side?

 Imo, simply use {{{--disable-decoder=jpeg2000}}}
