Yes, the frames at the libmpeg2 output are in yuv format.
(note the pgm output is already pretty raw too - it just adds a small

routine for that in libvo, its called yuv2rgb

There is not specific macos maintainer. This list is the right place

Do you have any specific problems or features you'd like to see
implemented ?
