2013-05-27a few clean-upsYaowu Xu
1. remove prediction mode conversion 2. unified bmode, same for key and non-key frame 3. set I4X4_PRED count for pdf to 0, as I4X4_PRED is no longer coded ever. It is determined by ref_frame and block partition Change-Id: If5b282957c24339b241acdb9f2afef85658fe47d

2013-05-27Merge "Reduce bmi buffer length from 16 to 4" into experimentalJingning Han
2013-05-27Reduce bmi buffer length from 16 to 4Jingning Han
This commit removes the use of bmi_ in the first-pass encoding by forcing encode_intra4x4block_ to use DC_PRED, followed by DCT_DCT only, as John suggested. This makes the need for bmi buffer only up to 4 entries, instead of 16. Change-Id: I3410007dfae789ee46a09ae20c39d3ce3c7954aa

2013-05-22Using 128 entry look up table for coef modelsDeb Mukherjee
Reverts to using 128 bit LUT for the coef models rather than 48 to ease hardware implementation. Also incorporates some cleanups including removing various hooks to support different lookup tables based on block_type and ref_type. Change-Id: I54100c120cca07a2ebd3a7776bc4630fa6a153f6
2013-05-22changes intra coding to be based on txfm blockYaowu Xu
This commit changed the encoding and decoding of intra blocks to be based on transform block. In each prediction block, the intra coding iterates thorough each transform block based on raster scan order. This commit also fixed a bug in D135 prediction code. TODO next: The RD mode/txfm_size selection should take this into account when computing RD values. Change-Id: I6d1be2faa4c4948a52e830b6a9a84a6b2b6850f6

2013-05-21Make the intra rd search support 8x4/4x8Jingning Han
This commit allows the rate-distortion optimization of intra coding capable of supporting 8x4 and 4x8 partition settings. It enables the entropy coding of intra modes in key frame using a unified contextual probability model conditioned on its above/left prediction modes. Coding performance: derf 0.464% Change-Id: Ieed055084e11fcb64d5d5faeb0e706d30268ba18

Right now moving clr_type, error_resilient_mode, refresh_frame_context, frame_parallel_decoding_mode from first compressed partition to uncompressed frame part.

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

2013-05-20Give 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.
