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

2011-09-13Change to segment_feature_data[][] structure.Paul Wilkins
This data structure is now [Segment ID][Features] rather than [Features][Segment_ID] I propose as a separate modification to make the experimental bit stream reflect this such that all the features for a segment are coded together. Change-Id: I581e4e3ca2033bdbdef3d9300977a8202f55b4fb

2011-08-24Removed bmi copy to/from BLOCKDScott LaVarnway
for SPLITMV and B_PRED modes. Modified code to use the bmi found in mode_info_context instead of BLOCKD. On the decode side, the uvmvs are calculated only when required, instead of every macroblock. This is WIP. (bmi should eventually be removed from BLOCKD) Small performance gains noticed for RT encodes and decodes.(VGA) Change-Id: I2ed7f0fd5ca733655df684aa82da575c77a973e7

2011-08-23Fix data accesses for simple loopfiltersJohann
The data that the simple horizontal loopfilter reads is aligned, treat it accordingly. For the vertical, we only use the bottom 4 bytes, so don't read in 16 (and incur the penalty for unaligned access). This shows a small improvement on older processors which have a significant penalty for unaligned reads. postproc_mmx.c is unused Change-Id: I87b29bbc0c3b19ee1ca1de3c4f47332a53087b3d
2011-08-23Use local labels for jumps/loops in x86 assembly.Fritz Koenig

2011-08-19Merge "Copy less when active map is in use"John Koleszar
2011-08-19Copy less when active map is in useAlpha Lam
When active map is specified and the current frame is not a key frame, golden frame nor a altref frame then copy only those active regions. This significantly reduces encoding time by as much as 19% on the test system where realtime encoding is used. This is particularly useful when the frame size is large (e.g. 2560x1600) and there's only a few action macroblocks. Change-Id: If394a813ec2df5a0201745d1348dbde4278f7ad4

2011-08-12Disable error concealment until first key frame is decodedStefan Holmer
When error concealment is enabled the first key frame must be successfully received before error concealment is activated. Error concealment will be activated when the delta following delta frame is received. Also fixed a couple of bugs related to error tracking in multi-threading. And avoiding decoding corrupt residual when we have multiple non-resilient partitions. Change-Id: I45c4bb296e2f05f57624aef500a874faf431a60d
