2017-11-13New content type to improve grain retention.paulwilkins
For new VP9 only content type adjust the rate distortion and ARF filter based on the relative spatial variance of the source and reconstruction. In regards to the RD loop the method favors modes where the reconstruction variance is similar to the source variance. However it is currently only applied to regions where the source variance is quite low. For very low variance blocks it applies a further bias against intra coding and large prediction block sizes (the later in particular limit the usefulness of the loop filter). The final part of this change is to lower the strength of the ARF filter for blocks where the source has very low spatial variance, to encourage some low amplitude texture or noise to pass through the filter. This change improves the retention of film grain and fine noise / texture in spatially flat regions, but as expected causes a significant drop in PSNR on many clips. This is to be expected because similar but misaligned noise or texture will give a lower PSNR than a flat noise free reconstruction. However, it is worth noting that most clips show a strong gain in FAST SSIM. The features are enabled on the vpxenc command line by setting --tune-content=film. VPX_ENCODER_ABI_VERSION bumped for this change and cvbr. Change-Id: I26a4e4edfa3dc5cacead82fa701fe7a9118ccd0a
2017-11-08CVBR command line option.paulwilkins
Added command line control of Corpus VBR. The new corpus vbr mode is a variant of standard VBR (end-usage=0) where the complexity distribution mid point is passed in rather than calculated for a specific clip or chunk. The new variant is enabled by setting a new command line parameter --corpus-complexity to a zero value. Omitting this parameter or setting it to 0 will cause the codec to use standard vbr mode. The correct value for a given corpus needs to be derived experimentally using a training set such that the average rate for the corpus is close to the target value. For example our using our low res test set with upper and lower vbr limits of 50%-150% and a corpus complexity value of 650 gives a similar average data rate across the set to using standard vbr. However, with the corpus mode easier clips will be allocated fewer bits and harder clips more bits rather than having the same rate target for all.

2017-09-14VP9 level targeting: add a new AUTO modeHui Su
In the new AUTO mode, restrict the minimum alt-ref interval and max column tiles adaptively based on picture size, while not applying any rate control constraints. This mode aims to produce encodings that fit into levels corresponding to the source picture size, with minimum compression quality lost. However, the bitstream is not guaranteed to be level compatible, e.g., the average bitrate may exceed level limit. BUG=b/64451920 Change-Id: I02080b169cbbef4ab2e08c0df4697ce894aad83c

2017-02-27vp9: Rename new_mt to row_mtVignesh Venkatasubramanian
new_mt is a very generic name that will get obsolete soon enough. Since this is exposed as a codec control, renaming it to row_mt to signify row level paralellism. Also renaming the ETHREAD_BIT_MATCH codec control to ROW_MT_BIT_EXACT. Change-Id: Ic7872d78bb3b12fb4cf92ba028ec8e08eb3a9558

2016-07-18vp9: Allow usage of lookahead for real-time, 1 pass vbr.Marco
Allow usage of lookahead for VBR in real-time mode, for 1 pass vbr. Current usage is for fast checking of future scene cuts/changes, and adjusting rate control (gf interval and active_worst/target size). Added unittests (datarate) for 1 pass vbr mode, with non-zero lag. Added an experimental option to limit QP based on lookahead. Overall positive gain in metrics on ytlive set: avgPNSR/SSIM up on average ~1-3%; several clips up by 5, 7%. Change-Id: I960d57dfc89de121c4824b9a9bf88d2814e74b56

2016-03-22Prevent encoder crash caused by row tile dependenciesYunqing Wang
In multi-thread case, the encoder may crash if using encoder option tile-rows > 0. To prevent that, force tile-rows=0 in this situation. This is a workaround for WebM issue 1095: https://bugs.chromium.org/p/webm/issues/detail?id=1095 The further fix can be done by adding synchronizations after a tile row is encoded. But this will hurt multi-threaded encoder performance. So, it is recommended to use tile-rows=0 while encoding with threads > 1. Change-Id: I656cbcc200f8d0410d09530e7981ad8f32fe7bc9
2016-02-25vp9: set kf_max_dist to a reasonable default (128)James Zern

CONFIG_VP9_HIGHBITDEPTH is currently used by both vp9 and vp10, but in many place outside vp9/vp10, the macro was used in conjunction of CONFIG_VP9. This created a dependency on vp9 for vp10 to build. This commit removes the dependency by use CONFIG_VP9_HIGHBITDEPTH only in these places. Change-Id: I8cc007fc9cf132394c6498ce6759e606b64a6ad0

2015-07-06Expose params min-gf-interval/max-gf-intervalDebargha Mukherjee
Adds two new vp9 parameters --min-gf-interval and --max-gf-interval to enable testing based on frequency of alt-ref frames. Also adds a unit-test to test enforcement of min-gf-interval. For both these parameters the default value is 0, which indicates they are picked by the encoder, based on resolution and framerate considerations. If they are greater than zero, the specified parameter is honored. (Additional note by paulwilkins) Note that there is a slight oddity in that key frames are also GFs and considered part of GF only group. However they are treated as not being part of an arf group because for arf groups the previous GF is assumed to be the terminal or overlay frame for the previous group.
