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

2012-06-11Fix pedantic compiler warningsJohn Koleszar
Allows building the library with the gcc -pedantic option, for improved portabilty. In particular, this commit removes usage of C99/C++ style single-line comments and dynamic struct initializers. This is a continuation of the work done in commit 97b766a46, which removed most of these warnings for decode only builds. Change-Id: Id453d9c1d9f44cc0381b10c3869fabb0184d5966

2012-04-25Have vpxenc use a default kf_max_rate of 5 seconds.Ralph Giles
Rather than using the static default maximum keyframe spacing provided by vpx_codec_enc_config_default() set the default value to 5 times the frame rate. Five seconds is too long for live streaming applications, but is a compromise between seek efficiency and giving the encoder freedom to choose keyframe locations. The five second value is from James Zern's suggestion in http://article.gmane.org/gmane.comp.multimedia.webm.user/2945 Change-Id: Ib7274dc248589c433c06e68ca07232e97f7ce17f

2012-04-11Superblock encoding orderAdrian Grange
This is the first patch to add superblock (32x32) coding order capabilities. It does not yet do any mode selection at the SB level, that will follow in a further patch. This patch encodes rows of SBs rather than MBs, each SB contains 2x2 MBs. Two intra prediction modes have been disabled since they require reconstructed data for the above-right MB which may not have been encoded yet (e.g. for the bottom right MB in each SB). Results on the one test clip I have tried (720p GIPS clip) suggest that it is somewhere around 0.2dB worse than the baseline version, so there may be bugs. It has been tested with no experiments enabled and with the following 3 experiments enabled: --enable-enhanced_interp --enable-high_precision_mv --enable-sixteenth_subpel_uv in each case the decode buffer matches the recon buffer (using "cmp" to compare the dumped/decoded frames). Note: Testing these experiments individually created errors. Some problems were found with other experiments but it is unclear what state these experiments are in: --enable-comp_intra_pred --enable-newentropy --enable-uvintra This code has not been extensively tested yet, so there is every likelihood that further bugs remain. I also intend to do some code cleanup & refactoring in tandem with the next patch that adds the 32x32 modes. Change-Id: I1eba7f740a70b3510df58db53464535ef881b4d9

2012-03-14Added encode/decode recon buffer match test to vpxencYaowu Xu
The commit added a new command line option --test-decode to vpxenc. The option enables encoder to decode compressed frames and test recon buffers from the decode against those from encode for mismatch. There are a few limitations on this option currently, one of them being the match test is not done on a number of lagged frames at the end of an encoding.

2012-03-07Changed MAX_PSNR to be consistent with internal statsYaowu Xu

2012-02-29vpxenc: fix time and fps calculation in 2-pass encodingYunqing Wang
When we do 2-pass encoding, elapsed time is accumulated through whole 2-pass process, which gives incorrect time and fps results for second pass. This change fixed that by resetting the time accumulator for second pass. Change-Id: Ie6cbf0d0e66e6874e7071305e253c6267529cf20
2012-02-29Packing bitstream on-the-fly with delayed context updatesAttila Nagy
Produce the token partitions on-the-fly, while processing each MB. Context is updated at the beginning of each frame based on the previoud frame's counters. Optimally encoder outputs partitions in separate buffers. For frame based output, partitions are concatenated internally. Limitations: - enabled just in combination with realtime-only mode - number of encoding threads has to be equal or less than the number of token partitions. For this reason, by default the encoder will do 8 token partitions. - vpxenc supports partition output (-P) just in combination with IVF output format (--ivf) Performance: - Realtime encoder can be up to 13% faster (ARM) depending on the number of threads and bitrate settings. Constant gain over the 5-16 speed range. - Token buffer reduced from one frame to 8 MBs Quality: - quality is affected by the delayed context updates. This again dependents on input material, speed and bitrate settings. For VC style input the loss seen is up to 0.2dB. If error-resilient=2 mode is used than the effect of this change is negligible. Example: ./configure --enable-realtime-only --enable-onthefly-bitpacking ./vpxenc --rt --end-usage=1 --fps=30000/1000 -w 640 -h 480 --target-bitrate=1000 --token-parts=3 --static-thresh=2000 --ivf -P -t 4 -o strm.ivf tanya_640x480.yuv Change-Id: I127295cb85b835fc287e1c0201a67e378d025d76
2012-02-16vpxenc: initial implementation of multistream supportJohn Koleszar
Add the ability to specify multiple output streams on the command line. Streams are delimited by --, and most parameters inherit from previous streams. In this implementation, resizing streams is still not supported. It does not make use of the new multistream support in the encoder either. Two pass support runs all streams independently, though it's theoretically possible that we could combine firstpass runs in the future. The logic required for this is too tricky to do as part of this initial implementation. This is mostly an effort to get the parameter passing and independent streams working from the application's perspective, and a later commit will add the rescaling and multiresolution support.
