2013-11-06Merge "Move SVC per-frame loop from sample app into libvpx proper"Ivan Maltz
2013-11-06Move SVC per-frame loop from sample app into libvpx properIvan Maltz
SVC multiple layer per frame encoding is invoked with vpx_svc_init and vpx_svc_encode. These interfaces are designed to be invoked from ffmpeg. Additional improvements: - make dummy frame handling a bit more explicit - fixed bug with single layer encodes - track individual frame sizes and psnrs instead of averages - parameterized quantizer, 16th scalefactors, more logging, - enabled single layer encodes to generate baseline - include new mode for 3 layer I frame with 5 total layers Change-Id: I46cfa600d102e208c6af8acd6132e0cc25cda8d4

2013-09-06Support a constant quality mode in VP9Deb Mukherjee
Adds a new end-usage option for constant quality encoding in vpx. This first version implemented for VP9, encodes all regular inter frames using the quality specified in the --cq-level= option, while encoding all key frames and golden/altref frames at a quality better than that. The current performance on derfraw300 is +0.910% up from bitrate control, but achieved without multiple recode loops per frame. The decision for qp for each altref/golden/key frame will be improved in subsequent patches based on better use of stats from the first pass. Further, the qp for regular inter frames may also be varied around the provided cq-level. Change-Id: I6c4a2a68563679d60e0616ebcb11698578615fb3

2013-06-17Change the encryption feature to use a callback for decryption.Jeff Petkau

Adds a new experiment CONFIG_NON420 that allows other chroma subsamplings to be passed to the codec. This commit allows the data to be passed from a y4m input file through vpxenc to the codec, where they're currently rejected. Later commits will finish support for this inside the codec.

2013-04-24Extension of segmentation to 8 segments.Paul Wilkins
Also some further simplification following removal of top node code. There is an issue in regards to the shared file vp8cx.h in regard to the roi_map as this interface assumes that there are only 4 segments. I have left the value here as 4 for now meaning that the roi_map interface is broken for VP9. Note that this change would have been easier if I hadn't had to search for hard wire instances of the number 4 and <= 3. Change-Id: Ia8b6deea4be4dbd20deb1656e689dd43a5f190e8

2013-02-13Add support for tile rows.Ronald S. Bultje
These allow sending partial bitstream packets over the network before encoding a complete frame is completed, thus lowering end-to-end latency. The tile-rows are not independent. Change-Id: I99986595cbcbff9153e2a14f49b4aa7dee4768e2
2013-02-12Add tile column size limits (256 pixels min, 4096 pixels max).Ronald S. Bultje

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

2012-11-15Pack invisible frames without lengthsJohn Koleszar
Modify the decoder to return the ending position of the bool decoder and use that as the starting position for the next frame. The constant-space algorithm for parsing the appended frame lengths is O(n^2), which is a potential DoS concern if n is unbounded. Revisit the appended lengths for use as partition lengths when multipartition support is added. In addition, this allows decoding of raw streams outside of a container without additional framing information, though it's insufficient to be able to remux said stream into a container.

2012-11-09Packing Altref along with succeeding frame and length encoding framesVignesh Venkatasubramanian
The altref frame is packed along with the next P frame. So that outside of the codec there are now only two types of frames P and I. Also, now it is one frame in and one frame out with respect to the codec. Apart from that, all the frames are length encoded with the length of each frame appended to the frame itself. There are two categories of frames and each of them will look as follows: - Packed frames (an altref along with the succeeding p frame) - altref_frame_data | altref_lenngth | frame_data | length - Unpacked frames (all frames other than the above) - frame_data | length Change-Id: If1eabf5c473f7d46b3f2d026bd30c803588c5330
2012-11-07Rough merge of master into experimentalJohn Koleszar
Creates a merge between the master and experimental branches. Fixes a number of conflicts in the build system to allow *either* VP8 or VP9 to be built. Specifically either: $ configure --disable-vp9 $ configure --disable-vp8 --disable-unit-tests VP9 still exports its symbols and files as VP8, so that will be resolved in the next commit. Unit tests are broken in VP9, but this isn't a new issue. They are fixed upstream on origin/experimental as of this writing, but rebasing this merge proved difficult, so will tackle that in a second merge commit.

2012-06-28Add lossless compression mode.Hui Su
This commit adds lossless compression capability to the experimental branch. The lossless experiment can be enabled using --enable-lossless in configure. When the experiment is enabled, the encoder will use lossless compression mode by command line option --lossless, and the decoder automatically recognizes a losslessly encoded clip and decodes accordingly. To achieve the lossless coding, this commit has changed the following: 1. To encode at lossless mode, encoder forces the use of unit quantizer, i.e, Q 0, where effective quantization is 1. Encoder also disables the usage of 8x8 transform and allows only 4x4 transform; 2. At Q 0, the first order 4x4 DCT/IDCT have been switched over to a pair of forward and inverse Walsh-Hadamard Transform (http://goo.gl/EIsfy), with proper scaling applied to match the range of the original 4x4 DCT/IDCT pair; 3. At Q 0, the second order remains to use the previous walsh-hadamard transform pair. However, to maintain the reversibility in second order transform at Q 0, scaling down is applied to first order DC coefficients prior to forward transform, and scaling up is applied to the second order output prior to quantization. Symmetric upscaling and downscaling are added around inverse second order transform; 4. At lossless mode, encoder also disables a number of minor features to ensure no loss is introduced, these features includes: a. Trellis quantization optimization b. Loop filtering c. Aggressive zero-binning, rounding and zero-bin boosting d. Mode based zero-bin boosting Lossless coding test was performed on all clips within the derf set, to verify that the commit has achieved lossless compression for all clips. The average compression ratio is around 2.57 to 1. (http://goo.gl/dEShs) Change-Id: Ia3aba7dd09df40dd590f93b9aba134defbc64e34
