[FFmpeg-devel] yuv420_bgr24_mmxext conversion taking significant time

I have a workload which spends a significant amount of time (~10%) in
the yuv420_bgr24_mmxext function in FFMEPG.
I looked at the assembly and profile and see MMX (64 bit) registers are
used. I wonder whether we can have a SSE2 version which has a register bit
width of 128.
I am very interested in implementing such support if it is possible.
