2011-09-16add 8x8 intra prediction modesYaowu Xu
Patch 1 to Patch 3 is an initial implementation of 8x8 intra prediction modes, here are with the following assumptions: a. 8x8 has 4 prediction modes DC, H, V and TM b. UV 4x4 block use the same mode as corresponding 8x8 area c. i8x8 modes are enabled for key frame only for now Patch 4: d. removed debug code from previous patches Patch 5: e. added stats code to collect entropy stats and further cleaned up Patch 6: f. changed mode stats code to collect finer stats of modes Patch 7: g. normalized i8x8 modes distribution to total at 256 (8bits). Patch 8: h. fixed a bug in decoder and removed debug printf output. Patch 9: i. more cleanups to address paul's comment Patch 10: j. messy rebase/merges to bring the commit up to date. Tests on HD clips encoded with all key frame showing consistent gain on all clips and all metrics:~0.5%(psnr) and 0.6%(ssim): http://www.corp.google.com/~yaowu/no_crawl/i8x8hd_allkey_fixedq.html To build and test, configure with: --enable-experimental --enable-i8x8 Change-Id: I9813fe07ae48cab5fdb5d904bca022514ad01e7f
2011-09-13Segment Features:Paul Wilkins
Some basic plumbing added for a range of segment level features. MB_LVL_* changed to SEG_LVL_* to better reflect meaning. Change-Id: Iac96da36990aa0e40afc0d86e990df337fd0c50b

2011-07-21fix more merge issuesYaowu Xu
With this fix, the experimental branch now builds and encodes correctly with the following two configure options respectively: --enable-experimental --enable-t8x8 --enable-experimental Change-Id: I3147c33c503fe713a85fd371e4f1a974805778bf

2011-07-19Moved vp8_encode_bool into boolhuff.hScott LaVarnway
allowing the compiler to inline this function. For real-time encodes, this gave a boost of 1% to 2.5%, depending on the speed setting. Change-Id: I3929d176cca086b4261267b848419d5bcff21c02

2011-06-28Use MAX_ENTROPY_TOKENS and ENTROPY_NODES more consistentlyJohn Koleszar
There were many instances in the code of vp8_coef_tokens and vp8_coef_tokens-1, which was a preprocessor macro despite the naming convention. Replace these with MAX_ENTROPY_TOKENS and ENTROPY_NODES, respectively. Change-Id: I72c4f6c7634c94e1fa066cd511471e5592c748da
2011-06-28Adding support for independent partitionsStefan Holmer
Adding support in the encoder for generating independent residual partitions by forcing equal probabilities over the prev coef entropy contexts. Change-Id: I402f5c353255f3ca20eae2620af739f6a498cd21

2010-12-14shrink TOKENEXTRA and vp8_extra_bit_structJohann
Per John's previous change, shrink TOKENEXTRA from 20 to 8 bytes original: b7b1e6fb reverted: 41f4458a Also drop unused field from vp8_extra_bit_struct Update ARM ASM to deal with this change. In particular, Extra is signed and needs to be sign-extended when loaded. Change-Id: Ibd0ddc058432bc7bb09222d6ce4ef77e93a30b41

2010-12-09vp8 fast quantizer sse2 optimizations for eob.Fritz Koenig
Changed the end of block computation to use pmaxw. Removed additional pushing and popping of registers that was not needed. Change-Id: I08cb9b424513cd8a2c7ad8cea53b4e2adc66ef98
2010-11-18extends the range of tokensYaowu Xu
Extending the value range of tokens allows further experiments on extending quantizer range. Encoder and decoder were verified to produce matching reconstructed buffers by tests with forced quantized value of 1. Change-Id: I12faf92832867870b6f71ddeafbf643f1040086d
