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

2013-05-23Removed code not in useYaowu Xu
As intra coded blocks are always decoded using decode_sb_intra(), this commmit removed the code no longer in use. Change-Id: I09f14fa9cdc875656e8fbe245f72c8fd83b9e31e
2013-05-23Change txfm_type decisionYaowu Xu
The changing in intra coding to base on transform block, i.e. pred-> txfm->quant->dequant-itxfm->recon, made all blocks within a prediction unit behave consistently, there is no longer a need to handle blocks differently based on the position within a predicitn block. So this commit simplifies the decision of transform type to be based on prediction mode only. Change-Id: If96cb72386f2e9186126ace88afa35ef085b6c96
2013-05-23Fix a bug in intra4x4 level rd loopJingning Han

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

2013-05-21Adding API to read/write uncompressed frame header bits.Dmitry Kovalev
The API is not final yet and can be changed. Actual layout of uncompressed frame part will be finalized later. Right now moving clr_type, error_resilient_mode, refresh_frame_context, frame_parallel_decoding_mode from first compressed partition to uncompressed frame part.

2013-05-21Refinements 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
