Happy to see j2k encoding support for a few pixel formats. I'd love to see
support for yuv422p and yuv422p10le. When I take yuv422p content as an
input, the j2k encoder auto-selects rgb24 even if I state yuv422p encoding
explicitly. Here's an output.
ffmpeg -y -t 1 -i OUT2.mov -vcodec j2k -pix_fmt yuv422p -an -strict
experimental testj2k.mov
