Ronald S. Bultje	70d418c7e6	Revert "PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD." This reverts commit `1df908f33f`. The expected performance improvements are essentially non-existent.	9 years ago
Dan Parrot	1df908f33f	PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD. 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.

Derek Buitenhuis	21f9468402	avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago

Ganesh Ajjanagadde	b4cb597900	libswscale/swscale: fix -Wunused-function hyscale, hcscale are only used in old filter code, hence place header guard to silence -Wunused-function.

Ganesh Ajjanagadde	80d23d9d32	swscale/swscale: silence unused function warning gamma_convert is only used with the old code. Thus, it is placed under a header guard. This patch silences a -Wunused-function observed on GCC 5.2. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
