* Revert "PPC64: Add versions of functions in libswscale/input.c optimized for ↵Ronald S. Bultje2016-07-11
| | | | | | | POWER8 VSX SIMD." This reverts commit 1df908f33f658979b32599489ca6f1a39821013c. The expected performance improvements are essentially non-existent.
* PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 ↵Dan Parrot2016-06-30
| | | | | | | | | | 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. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| * avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8Vittorio Giovara2014-08-04
| | | | | | | | | | | | | | The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.
