[FFmpeg-devel] [PATCH] swscale: have --enable-runtime-cpudetect actually detect cpu capabilities at runtime

[Darren Horrocks]

Hi,

used av_get_cpu_flags to get all cpu capabilities, then checked for
mmx2 mmx and 3dnow.

if the cpu supports any of these, it gets added to the flags for use later.

Regards,
Darren Horrocks
