This matches the behavior prior to generalizing the frame context selection, and intuitively makes sense in that the first forward ref is immediately after the keyframe, so it's quality is improved a bit by using the keyframe's entropy context rather than the default.

The loop filtering used for MB edge or internal edge of a MB using 8x8 tranform was reading 5 pixel each side and writting 3 pixel each side. With suggestion from Aki and Scott on hardware&software performance, this commit changed to read 4 pixel each side and write 3 pixel each side. Change-Id: I584393906c4f5f948a581d6590959522572743bb

This commit restores the quality lost when the buffer-to-buffer copy logic was removed. Note that this is specific to the current use of golden frames and will need rework when RTC functionality is added. Change-Id: I7324a75acd96eafd9e0f9b8633d782e390d5dc21

Previously there were two frame coding contexts tracked, one for normal frames and one for alt-ref frames. Generalize this by signalling the context to use in the bitstream, rather than tieing it to the alt ref refresh bit. Also increase the number of contexts available to 4, which may be useful for temporal scalability. Change-Id: I7b66daaddd55c535c20cd16713541fab182b1662

Remove lst_fb_idx, gld_fb_idx, alt_fb_idx, refresh_last_frame, refresh_golden_frame, refresh_alt_ref_frame from common. Gold/Alt are encode side conventions. From the decoder's perspective, we want to be dealing with numbered references. Updates to active_ref 2 signal mode context switches, vestigial from refresh_alt_ref_frame. This needs some clean up to make sense with increased numbers of reference frames, as well as reimplementing the swapping of alt/golden which was previously done using the buffer-to-buffer copy mechanism removed in an earlier commit.

This is the first in a series of commits to add additional reference frames to the codec. Each frame will be able to update any of the available references, but copying between references is not supported. Change-Id: I5945b5ce6cc3582c495102b4e7eed4f08c44d5a1

In commit 9a1d73d0, loop filtering was added for UV 4x4 boundaries when TX_8X8 is used by a MB. This commit further refined the decision to be based on the actual transform used for the UV planes. When UV planes use 4x4 transform, i.e. when prediction mode used is either I8X8_PRED or SPLITMV, UV planes are filtered on 4x4 boundaries, and no filtering is applied on 4x4 block boundaries when UV planes use 8X8 transform.

This prevents ill-defined behaviour, such as setting x->skip for a mode that is excluded because of frame-level flags (e.g. filter selection, compound prediction selection), then not breaking out of the RD loop because the mode is not allowed, but keeping the flag on. Whatever mode is iterated through next in the RD loop will then carry this flag, and all sort of bad stuff happens, such as x->skip being set on intra pred modes.

Fixes some scaling issues. Adds an option to only compute the dct on the low-low subband for 32x32 and 64x64 blocks using only a single 16x16 dct after 1 and 2 wavelet decomposition levels respectively. Also adds an option to use a 8x8 dct as building block. Currenlty with the 2/6 filter and with a single 16x16 dct on the low low band, the reuslts compared to full 32x32 dct is as follows: derf: -0.15% yt: -0.29% std-hd: -0.18% hd: -0.6% These are my current recommended settings, since the 2/6 filter is very simple. Results with 8x8 dct are about 0.3% worse. Change-Id: I00100cdc96e32deced591985785ef0d06f325e44
