      Initial version of alpha channel support · 679e4abd
      John Koleszar authored
      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.

      Subsampling aware allocs and bitstream · da58436f
      John Koleszar authored
      Make framebuffer allocations according to the chroma subsamping
      factors in use. A bit is placed in the raw part of the frame header for
      each of the two subsampling factors. This will be moved in a future
      commit to make them part of the TBD feature set bits, probably only set
      on keyframes, etc.

      Add VP9_GET_REFERENCE control · b3c350a1
      John Koleszar authored
      This is like VP8_COPY_REFERENCE, but returns a pointer to the reference
      frame rather than a copy of it. This is useful when the application
      doesn't know what the size of the reference is, as is the case when
      scaling is in effect.
