2021-04-20Further normalization of Vizier parameters.Paul Wilkins
Further changes to normalize the Vizier command line parameters. The intent is that the default behavior for any given parameter is signaled by the value 1.0 (expressed on the command line as a rational). The final values used in the two pass code are obtained by multiplying the passed in factors by a default values if use_vizier_rc_params is 1. Where use_vizier_rc_params is 0 the values are explicitly set to the defaults. This patch also changes the default value of each parameter to 1.0 even if not set explicitly. This should ensure safe /default behavior if the user sets use_vizier_rc_params to 1 but does not set all the the individual parameters. Change-Id: Ied08b3c22df18f42f446a4cc9363473cad097f69
2021-04-14Pass vizier rd parameter valuesCheng Chen
Add command line options for three rd parameters. They are controlled by --use_vizier_rc_params, together with other rc parameters. If not set from command line, current default values will be used. Change-Id: Ie1b9a98a50326551cc1d5940c4b637cb01a61aa0
2021-04-13Set vizier rc parametersCheng Chen
If pass --use-vizier-rc-params=1, the rc parameters are overwittern by pass in values. It --use-vizier-rc-params=0, the rc parameters remain the default values. Change-Id: I7a3e806e0918f49e8970997379a6e99af6bb7cac
2021-04-06Change zm_factor for Vizier.Paul Wilkins
Changes the exposed zm_factor parameter. This patch alters the meaning of the zm_factor parameter that will be exposed for the Vizier project. The previous power factor was hard to interpret in terms of its meaning and effect and has been replaced by a linear factor. Given that the initial Vizier results suggested a lower zero motion effect for all formats, the default impact has been reduced. The patch as it stands gives a modest improvement for PSNR but is slightly down on some sets for SSIM (overall psnr, ssim % bdrate change: -ve is better) lowres -0.111, 0.001 ugc360p -0.282, -0.068 midres2 -0.183, 0.059 hdres2 -0.042, 0.172 Change-Id: Id6566433ceed8470d5fad1f30282daed56de385d

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

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.

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
