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.

2014-03-25swscale: add two spatially stable dithering methodsØyvind Kolås
Both of these dithering methods are from http://pippin.gimp.org/a_dither/ for GIF they can be considered better than bayer (provides more gray-levels), and spatial stability - often more than twice as good compression and less visual flicker than error diffusion methods (the methods also avoids error-shadow artifacts of diffusion dithers). These methods are similar to blue/green noise type dither masks; but are simple enough to generate their mask on the fly. They are still research work in progress; though more expensive to generate masks (which can be used in a LUT) like 'void and cluster' and similar methods will yield superior results

2013-10-30Optimize pure C unscaled yuv2rgb.Reimar Döffinger
Aligning the tables reduces the amount of code generated on e.g. ARM as the offset constant then has few enough set bits so it can be encoded inside a single instruction instead of 2. Ideally all should be declared aligned, but the DECLARE_ALIGNED macros does not work with pointer tables, thus also reordered the tables. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
