Michael Niedermayer 026f243d71 avcodec/utils: Optimize ff_color_frame() using memcpy() 4650975 -> 4493240 dezicycles This optimizes lines 2 and later. Line 1 still uses av_memcpy_backptr() This change originally fixed ossfuzz 10790 but this is now fixed by other optimizations already Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> (cherry picked from commit `95e5396919`) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>		2019-12-31 19:51:55 +01:00
