2014-08-12lsws: duplicate ff_log2_tabJames Almer
libswscale uses the table but wasn't duplicating it like the rest of the libs. This should fix compilation failures on msvc/icl after lavu stopped exporting internal functions and tables. Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

2014-08-04swscale: support AV_PIX_FMT_YA16 as inputVittorio Giovara
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.

2014-06-02Remove all Blackfin architecture optimizationsDiego Biurrun
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.
