2016-04-04vp8-denoiser: Avoid doing the mcomp if we don't denoise.Marco
Avoid doing the mcomp in denoiser if we don't denoise the block (because of motion/SSE/skin threshold, etc). This can reduce encoding time (with denoiser enabled) by ~1.5-2%. Change-Id: Ia699b68dfd37b89cdf3a82b8aa40e8c8f98a3d4f
2016-04-01vp8 denoiser: Some adjustments to usage of skin and motion.Marco
Switch to use new skin model. And fix condition for denoising skin block. Previous condition did not denoise skin blocks if the selected mode was non-zero motion in current frame. Modify condition to also force no denoising if that mode was not selected as zero motion now and for at least "x" past frames in a row (x = 2). Change-Id: I00753e3fe45b9a308a7ef43c58f11868e3bfc6b0

2016-03-22Merge "Simplify the loopfilter synchronization logic in VP8 encoder"Yaowu Xu
2016-03-22Simplify the loopfilter synchronization logic in VP8 encoderYunqing Wang
This patch was to fix a reported Hangouts deadlock/freezing issue in VP8 encoder(issue 27232610). The original encoder loopfilter synchronization happened in the following frame, which was prone to causing problems in some complex use cases. This patch simplified the synchronization logic. More testing needs to be done. Change-Id: I38fd3f35d11f98fae1e44546aa5e4c6d6e19c4be

2016-01-28vp9/10: fix encoder crash on flushJames Zern
the lookahead buffer allocation is deferred to receipt of the first frame to allow profile changes. if the encoder was flushed before supplying any frames the encoder would crash trying to dereference the NULL buffer. vp8 is unaffected. fixes mozilla bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1237848 Change-Id: Icee4b64de760476eee0d33b568f0a1010335ff13

2016-01-08Amend and improve VP8 multithreading implementationYunqing Wang
There are flaws in current implementation of VP8 multithreading encoder and decoder as reported in the following issue: https://code.google.com/p/chromium/issues/detail?id=158922 Although the data race warnings are harmless, and wouldn't cause real problems while encoding and decoding videos, it is better to fix the warnings so that VP8 code could pass the TSan test. To synchronize the thread-shared data access and maintain the speed (i.e. decoding speed), use multiple mutexes based on mb_rows to reduce the number of synchronizations needed, make the reads and writes of the shared data protected, and reduce the number of mb_col writes by nsync times. The decoder speed tests showed < 3% speed loss while using 2 ~ 4 threads. Change-Id: Ie296defffcd86a693188b668270d811964227882
