John Koleszar 679e4abdd5 Initial version of alpha channel support ... This is a mostly-working implementation of an extra channel in the bitstream. Configure with --enable-alpha to test. Notable TODOs: - Add extra channel to all mismatch tests, PSNR, SSIM, etc - Configurable subsampling - Variable number of planes (currently always uses all 4) - Loop filtering - Per-plane lossless quantizer - ARNR support This implementation just uses the same contents as the Y channel for the A channel, due to lack of content and general pain in playing back 4 channel content. A later patch will use the actual alpha channel passed in from outside the codec. Change-Id: Ibf81f023b1c570bd84b3064e9b4b8ae52e087592		2013-05-16 22:21:09 -07:00
