Hi Carl,

Sorry for the missing performance info, I tested it with raw YUV format video, the command is:
./ffmpeg -pix_fmt yuv420p -s 1920*1080 -i input.yuv -vcodec rawvideo -s 1920*1080 -pix_fmt rgb24 -f null /dev/null
The outputs are as follows on my local machine:
output fmt RGB24:
	mmx: 337fps   ssse3: 634fps
 output fmt RGB32:
	mmx: 375fps   ssse3: 653fps
output fmt RGB555:
	mmx: 427fps   ssse3: 917fps
And I will add these infos in the PATCH V2.

Tank you
Tin Fu
