2013-04-29Use same intra prediction for all block sizeYaowu Xu
The commmit changed to use same intra prediction function for all block sizes. Some details on the changes: 1. All directional modes except DC/TM/V/H now have built-in filtering for all pixels with filter taps either (1, 2, 1)/4 or (1, 1)/2. 2. Above edge get automatic extended to double width (bw*2), which makes a lot of the prediciton mode computation simpler. 3. Same intra prediction function is called with different size for i4x4_pred and all other larger size. Overall, the change helped keyframe only coding for both cif size and std-hd size test sets by .5% consistently on all encodings. For normal coding with single/auto key frame, the change now also is consistently net positive for all encodings. The overall gains is about .15% on std-hd set.

2013-04-23Merge "Enable rectangular support for comp inter-intra" into experimentalJingning Han
2013-04-23Enable rectangular support for comp inter-intraJingning Han
This commit enables rectangular block prediction of compound inter-intra mode. It combines the mb/sb32/sb64 prediction functions into a unified version with configurable block width and height. This fixes the enc/dec mismatch of the codebase when comp-interintra-pred is enabled. Change-Id: I1d0db2f1f184007802df04fcd12b9dadb3189ff0

First in a series of commits moving the framebuffers pointers to per-plane data, so that they can be indexed numerically rather than by name. Change-Id: I6e0d60fd4d51e6375c384eb7321776564df21775
2013-04-18Make the use of pred buffers consistent in MB/SBJingning Han
Use in-place buffers (dst of MACROBLOCKD) for macroblock prediction. This makes the macroblock buffer handling consistent with those of superblock. Remove predictor buffer MACROBLOCKD. Change-Id: Id1bcd898961097b1e6230c10f0130753a59fc6df

2013-04-11WIP: removing predictor buffer usage from decoderScott LaVarnway
This patch will use the dest buffer instead of the predictor buffer. This will allow us in future commits to remove the extra mem copy that occurs in the dequant functions when eob == 0. We should also be able to remove extra params that are passed into the dequant functions. Change-Id: I7241bc1ab797a430418b1f3a95b5476db7455f6a

2013-02-20Avoid division in intra predictionTero Rintaluoma
- Using multiplication and shifting instead of division in intra prediction. - Maximum absolute difference is 1 for division statements in d45, d27, d63 prediction modes. However, errors can cumulate for large block sizes when using already predicted values. - Maximum number of non-matching result values in loops using division are: 4x4 0/16 8x8 0/64 16x16 10/256 32x32 13/1024 64x64 122/4096 Overall PSNR derf: 0.005 yt: -0.022 std-hd: 0.021 hd: -0.006 Change-Id: I3979a02eb6351636442c1af1e23d6c4e6ec1d01d
2013-02-05[WIP] Add column-based tiling.Ronald S. Bultje
This patch adds column-based tiling. The idea is to make each tile independently decodable (after reading the common frame header) and also independendly encodable (minus within-frame cost adjustments in the RD loop) to speed-up hardware & software en/decoders if they used multi-threading. Column-based tiling has the added advantage (over other tiling methods) that it minimizes realtime use-case latency, since all threads can start encoding data as soon as the first SB-row worth of data is available to the encoder. There is some test code that does random tile ordering in the decoder, to confirm that each tile is indeed independently decodable from other tiles in the same frame. At tile edges, all contexts assume default values (i.e. 0, 0 motion vector, no coefficients, DC intra4x4 mode), and motion vector search and ordering do not cross tiles in the same frame. t log Tile independence is not maintained between frames ATM, i.e. tile 0 of frame 1 is free to use motion vectors that point into any tile of frame 0. We support 1 (i.e. no tiling), 2 or 4 column-tiles. The loopfilter crosses tile boundaries. I discussed this briefly with Aki and he says that's OK. An in-loop loopfilter would need to do some sync between tile threads, but that shouldn't be a big issue. Resuls: with tiling disabled, we go up slightly because of improved edge use in the intra4x4 prediction. With 2 tiles, we lose about ~1% on derf, ~0.35% on HD and ~0.55% on STD/HD. With 4 tiles, we lose another ~1.5% on derf ~0.77% on HD and ~0.85% on STD/HD. Most of this loss is concentrated in the low-bitrate end of clips, and most of it is because of the loss of edges at tile boundaries and the resulting loss of intra predictors. TODO: - more tiles (perhaps allow row-based tiling also, and max. 8 tiles)? - maybe optionally (for EC purposes), motion vectors themselves should not cross tile edges, or we should emulate such borders as if they were off-frame, to limit error propagation to within one tile only. This doesn't have to be the default behaviour but could be an optional bitstream flag. Change-Id: I5951c3a0742a767b20bc9fb5af685d9892c2c96f

2012-12-18Use standard integer types for pixel values and coefficients.Ronald S. Bultje
For coefficients, use int16_t (instead of short); for pixel values in 16-bit intermediates, use uint16_t (instead of unsigned short); for all others, use uint8_t (instead of unsigned char). Change-Id: I3619cd9abf106c3742eccc2e2f5e89a62774f7da
2012-12-12Consistently use get_prob(), clip_prob() and newly added clip_pixel().Ronald S. Bultje
Add a function clip_pixel() to clip a pixel value to the [0,255] range of allowed values, and use this where-ever appropriate (e.g. prediction, reconstruction). Likewise, consistently use the recently added function clip_prob(), which calculates a binary probability in the [1,255] range. If possible, try to use get_prob() or its sister get_binary_prob() to calculate binary probabilities, for consistency. Since in some places, this means that binary probability calculations are changed (we use {255,256}*count0/(total) in a range of places, and all of these are now changed to use 256*count0+(total>>1)/total), this changes the encoding result, so this patch warrants some extensive testing.
