2015-01-30Try again to merge branch 'frame-parallel' into master branch.hkuang
In frame parallel decode, libvpx decoder decodes several frames on all cpus in parallel fashion. If not being flushed, it will only return frame when all the cpus are busy. If getting flushed, it will return all the frames in the decoder. Compare with current serial decode mode in which libvpx decoder is idle between decode calls, libvpx decoder is busy between decode calls. Current frame parallel decode will only speed up the decoding for frame parallel encoded videos. For non frame parallel encoded videos, frame parallel decode is slower than serial decode due to lack of loopfilter worker thread. There are still some known issues that need to be addressed. For example: decode frame parallel videos with segmentation enabled is not right sometimes. * frame-parallel: Add error handling for frame parallel decode and unit test for that. Fix a bug in frame parallel decode and add a unit test for that. Add two test vectors to test frame parallel decode. Add key frame seeking to webmdec and webm_video_source. Implement frame parallel decode for VP9. Increase the thread test range to cover 5, 6, 7, 8 threads. Fix a bug in adding frame parallel unit test. Add VP9 frame-parallel unit test. Manually pick "Make the api behavior conform to api spec." from master branch. Move vp9_dec_build_inter_predictors_* to decoder folder. Add segmentation map array for current and last frame segmentation. Include the right header for VP9 worker thread. Move vp9_thread.* to common. ctrl_get_reference does not need user_priv. Seperate the frame buffers from VP9 encoder/decoder structure.

2015-01-16vp9_ethread: add parallel loopfilterYunqing Wang
1. Added row-based loopfilter in encoder; 2. Moved common multi-threaded loopfilter functions from decoder to common; 3. Merged multi-threaded loopfilter code, and made encoder/ decoder call same function to reduce code duplication. Encoder tests showed that 1% - 2% speedup was seen for good-quality 2-pass mode(at speed 3); 1% - 3% speedup using 2 threads and 4% - 6% speedup using 4 threads were seen for real-time mode(at speed 7).

2014-01-31vp9 decoder: row-based multi-threaded loopfilterYunqing Wang
Implemented parallel loopfiltering, which uses existing tile- decoding threads. Each thread works on one row, and when that row is loopfiltered, it moves to next unattended row. To ensure the correct filtering order, threads are synchronized and one superblock is filtered only if the superblocks it depends on are filtered already. To reduce synchronization overhead and speed up the decoder, we use nsync > 1 for high resolution. Performance tests: 1. on desktop: 8-tile 4k video using 8 threads, speedup: 70% - 80% 4-tile HD video using 4 threads, speedup: ~35% 2. on mobile device(Nexus 7): 4-tile 1080p video using 4 threads, speedup: 18% - 25% 4-tile 1080p video using 2 threads, speedup: 10% - 15% Change-Id: If54b4a11960dd706c22d5ad145ad94156031f36a

2013-09-30Removing vp9_add_constant_residual_{8x8, 16x16, 32x32} functions.Dmitry Kovalev
We don't need these functions anymore. The only one which was actually used is vp9_add_constant_residual_32x32. Addition of vp9_short_idct32x32_1_add eliminates this single usage. SSE2 optimized version of vp9_short_idct32x32_1_add will be added in the next patch set, right now it is only C implementation. Now we have all idct functions implemented in a consistent manner.

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.
