[FFmpeg-devel] Which additional files need to be modified when adding PPC-specific version of libswscale/input.c

[Dan Parrot]

I am working on a patch to improve ffmpeg performance on PPC by using
vector SIMD facilities for those processor versions that have the
capability. 

There are 50 functions in libswscale/input.c that I am modifying. Adding
#ifdefs in all the functions probably isn't the way to go.

Is there a preferred method to implement such a change?

Thanks.
Dan Parrot.
