Exit early from function when supertx is used, rather than putting the bulk of the function body in a single conditional. Change-Id: I41f388a45bd46e4a6ee1c51f26782ed9bddff4e5

When using VARIANCE_AQ, we can change the segment assignment after initialising the quantiser in set_offsets, so re-initialise it when we do so. Change-Id: I1f168553aaf0ade419f0d4bf05820cd591b87659

Explicitly signal when the segment map is being refreshed when using VARIANE_AQ. This simplifies decisions about when the segment id needs to be set from the previous segment map vs based on the current variance. Change-Id: Ieb12c950e9cfbc3f53f4d184880071dea805563c

This commit combines uniform quantizer with trellis based coefficient level optimization. It improves the codebase compression performance: lowres 0.8% midres 1.0% hdres 1.6% Note that the current trellis optimization unit is using C code. This will make the cost of the overall quantization process slower. A number of optimizations will come up next. Change-Id: Id441dd238e4844409d0f08f82604be777f3f5282

This experiment implements non-uniform quantization where the width of the bins increases gradually to more closely match a laplacian distribution of the coeficcients. Performance Gain: derflr: 0.15% hevcmr: 0.675% Change-Id: I25234244e3bcd94b87c1f77cf682190b61c8ef94

Bring commits 575e81f7 and 3d6b8a66 to VP10. These changes predate the creation of the active map cyclic refresh test. BUG=https://bugs.chromium.org/p/webm/issues/detail?id=1224 Change-Id: I3559b6933ffa5649926a4b214e45ed0fae523a25

The assumption doesn't hold true in the current codebase. Remove this speed feature to simplify the codebase. Change-Id: I9b69f484c9b7cd612b825047cc5b2fce63ee0af7

The inter prediction residual can undergo different transform types during the rate-distortion optimization search. The assumption used in this speed feature no longer holds true. This commit removes the related code to clean up the codebase and clear out unit test failure in higher speed setting. Change-Id: I7f7cd4df2345ed3e607c9fae75b38cd2dbde0cac
