2016-07-11Revert "PPC64: Add versions of functions in libswscale/input.c optimized for ↵Ronald S. Bultje
POWER8 VSX SIMD." This reverts commit 1df908f33f658979b32599489ca6f1a39821013c. The expected performance improvements are essentially non-existent.
2016-06-30PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 ↵Dan Parrot
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>

Based on a long debug session with Kostya.
2014-08-04avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8Vittorio Giovara
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.

Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.
