Regarding this and x264 encoding: I had some full range 4:2:2 material
I was trying to encode with x264 a while back and found that if I
forced the "yuvj420p" pix format, FFmpeg would pass full range values
to x264. This was using x264 in pipe mode, but I don't see why it
wouldn't work with libx264. I would get very different results when
changing yuv420p to yuvj420p.
