[FFmpeg-devel] [PATCH] This patch addresses Trac ticket #5570. The optimized functions are in file libswscale/ppc/input_vsx.c. Each optimized function name is a concatenation of the corresponding name in libswscale/input.c with suffix _vsx. From bountysource https://www.bountysource.com/issues/34315232-power8-vsx-vectorization-libswscale-input-c (reverse_forever)

Sorry for title. It is my first experience in git send-email. Can I make 
a benchmark with handwritten tests or have some standard tool in ffmeg? 
And will the benchmark on x86-64 be informative?
