Martin Vignali	3af1c4ea7d	swscale : treat float input data as uint 16bpc Currently float are converted to 16b uint in input part using src depth (32 bits) in hScale16To19 and hScale16to15, make an invalid shift for the data So shift the value when using float input like 16 bpc uint.	6 years ago

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.	8 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	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
