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.

2015-01-23Replace divide with look-upYaowu Xu
This commit replaces an integer divide with a table-lookup. It is to improve decoding speed, and at the same time, to reduce possible complications with a bug in AMD Family 12h processors: "665 Integer Divide Instruction May Cause Unpredictable Behavior" Change-Id: I678b707a538798a923850bac467e66e847e6def7
2014-12-16Remove reset mode_info array per frameJingning Han
The mode_info array was unnecessarily reset to zero every frame when error resilient mode turned on, given that the mode info values per block will be assigned during mode search stage. This commit removes this reset operation. It reduces the runtime cost on memset operation to 1/3. The overall speed -6 runtime is reduced by 2%. Change-Id: I32ecb73338d8995cc0c5147de09357364f13d45b
2014-12-11Prevent decoder from using uninitialized entropy context.Alexander Voronov
If decoding starts with intra-only frame, there is a possibility of using uninitialized entropy context, what leads to undefined behavior. Change-Id: Icbb64b5b1bd1e5de2a4bfa2884e56bc0a20840af
2014-11-05Totally remove prev_mi in VP9 decoder.hkuang

2014-10-22vp9_ethread: allocate frame contexts outside VP9_COMMON structYunqing Wang
This patch allocated frame contexts outside VP9_COMMON. This allows multiple threads to share the same copy of frame contexts, and reduces the overhead. It also guarantees the correct update of these contexts during bitstream packing. This patch doesn't change encoding result. Change-Id: Ic181a2460b891d1d587278a6d02d8057b9dbd353

2014-02-13Removed the reset of mode_info from previous frameYaowu Xu
Prior to this commit, both encoder and decoder reset mode/mv info from previous frame in error resilient mode to ensure bitstreams are able to decode when there is loss of frame in decoder side. However, this is not necessary. This commit changed to remove the reset, so encoder can continue to use mode/mv/partition information from previously encoded frame without affecting decodeablilty under loss of frame.

2013-11-04Splitting partition_probs array into two arrays.Dmitry Kovalev
We only update partition_probs for inter frames but they are constant for key frames. It is not necessary to have constants inside frame context and copy them every time. This change reduces FRAME_CONTEXT size by at least 48 bytes. Change-Id: If70a53be51043f37fe7d113853217937710932a7
2013-11-01Removing 'new' probability calculation from convert_distribution().Dmitry Kovalev
We don't have to calculate 'new' probability in convert_distribution() because it is enough to calculate only 'new' counters which could be used to calculate probability if necessary. That's why removing a lot of unused temporary probability arrays and reducing number of get_binary_prob() calls. Change-Id: I4e14eb7203d1ace61bbddefd6b9b6326be83ba63

2013-09-11New mode_info_context storage -- undo revertScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of pointers to MODE_INFO structs. The MODE_INFO structs are now stored as a stream (decoder only), eliminating unnecessary copies and is a little more cache friendly. Change-Id: I031d376284c6eb98a38ad5595b797f048a6cfc0d

2013-09-06New mode_info_context storageScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of a pointer to a MODE_INFO struct and a "in the image" flag. The MODE_INFO structs are now stored as a stream, eliminating unnecessary copies and is a little more cache friendly. For the test clips used, the decoder performance improved by ~4.3% (1080p) and ~9.7% (720p). Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p) and 5.9% (720p).
