Comment (by Cigaes):

 Regarding your original problem, maybe look at the pixel format, I believe
 the default format negotiation has changed at some point before 1.2: you
 probably were encoding for yuv420p and now for yuv444p, which has better
 quality but is slower; {{{-pix_fmt yuv420p}}} should fix it.

 I do not know what will be faster: on one hand, yuv420p has the colorspace
 conversion, on the other hand rgb is not subsamples, benchmark is needed.
 Also, please remember that H.264 RGB is not standard.

 And of course, you should submit your patch to ffmpeg-devel as cehoyos
 suggested.
