2013-05-21Refinements on modelcoef expt to reduce storageDeb Mukherjee
Uses more aggrerssive interpolation to reduce storage for the model tables by almost more than half. Only 48 lists of probs are stored (as opposed to 128 before), corresponding to ONE_NODE probabilities of: 1, 3, 7, 11, ..., 115, 119, 127, 135, ..., 247, 255. Besides, only 1 table is used as opposed to 2 before. So the overall memory needed for the tables is just 48 * 8 = 384 bytes. The table currently used is based on a new Pareto distribution with heavier tail than a generalized Gaussian - which improves results on derf by about 0.1% over a single table Generaized Gaussian. Results overall on derfraw300 is -0.14%. Change-Id: I19bd03559cbf5894a9f8594b8023dcc3e546f6bd

2013-05-20Updating the model coef experimentDeb Mukherjee
Cleans up the experiment. Actually uses reduced counts for backward updates, and reduced number of probabilities in the context. No change in bitstream when the experiment is on. Between expt on and off: derfraw300 is down only -0.062% (which is better than when expts were run previously). Change-Id: I55285a049a0c22810bdb42914212ab5a4f8521b5
2013-05-20WIP: 4x4 idct/recon mergeScott LaVarnway
This patch eliminates the intermediate diff buffer usage by combining the short idct and the add residual into one function. The encoder can use the same code as well. Change-Id: I296604bf73579c45105de0dd1adbcc91bcc53c22

2013-05-20Give VP9 a different sync code from VP8Jingning Han
The new code is 0x49, 0x83, 0x42 There is nothing particularly special about this code bitstream wise. Its derivation is the word "sync" coded using 4x6bit alphabetic indices. Change-Id: Ie2430a854af32ddc5a5c25a6c1c90cf6497ba647
2013-05-19Enable bit-stream support to 8x4 and 4x8 partitionJingning Han
The recursive partition type search is enabled down to 4x4, 4x8 and 8x4, followed by the corresponding rate-distortion optimization for the per-partition encoding mode decisions. The bit-stream writing/reading synchronized in supporting the rectangular partition of 8x8 block. This provides above 1% coding performance gains on derf. To do next: 1. re-design the rate-distortion loop for inter prediction below 8x8. 2. re-design the rate-distortion loop for intra prediction below 4x4. 3. make the loop-filter aware of rectangular partition of 8x8 block. 4. clean the unused probability models. 5. update default probability values.

2013-05-17Replace default counts with default probs.Paul Wilkins
Replace vp9_kf_default_bmode_counts structure with direct default probabilities. The probability structure is smaller and it removes the need to specify in the bitstream how to convert the counts to probabilities. Note that I have concerns still about the size and value of the large intra mode context. This may cause problems for HW but it also means we rely heavily on reverse update as forwards update of a structure this size is problematic. I intend to review this more generally in the next few days to see if we can come up with a competitive solution that does not rely on such a large context.

2013-05-16Refactor encode_sb_ for 4x8/8x4 partitionJingning Han
Deprecate set_block_index. Replace it with get_sb_index_ for consistency with partition search and bit-stream writing/reading. Use b_width/height_log2 instead of mi_width/height_log2, to support 4x4 resolution partition types. Change-Id: Ic1e71981e163c669f7ea6b3c12b831c284c4a494

2013-05-16Use b_width_log2_ in partition type parseJingning Han
Replace mi_width/height_log2 with b_width/height_log2 in partition type parsing at bit-stream writing stage. This allows parsing resolution at 4x4 block level and makes the 4x4/4x8/8x4 partition coding consistent with other superblock types. Change-Id: I7db3617ea042e0db2dc898999b0c323bff91a22f

2013-05-16New inter mode context.Paul Wilkins
This patch creates a new inter mode contest that avoids a dependence on the reconstructed motion vectors from neighboring blocks. This was a change requested by a hardware vendor to improve decode performance. As part of this change I have also made some modifications to stats output code (under a flag) to allow accumulation of inter mode context flags over multiple clips Some further changes will be required to accommodate the deprecation of the split mv mode over the next few days. Performance as stands is around -0.25% on derf and std-hd but up on the YT and YT-HD sets. With further tuning or some adjustment to the context criteria it should be possible to make this change broadly neutral. Change-Id: Ia15cb4470969b9e87332a59c546ae0bd40676f6c
