[FFmpeg-devel] [PATCH] swscale: round on planar2x C code
Sun Sep 12 05:15:55 CEST 2010
The C and MMX2/3dnow code differ in planar2x due to pavgb's rounding.
Attached patch makes the output similar.
I couldn't measure any speed difference. gcc ends up using "leal
3(xxx)" instead of "leal (xxx)" which doesn't seem to have a speed
Otherwise we could put the MMX2/3dnow code under some if(flags &bitexact).
