2015-02-04Account for chroma component costs in RTC mode decisionJingning Han
This commit allows the encoder to account for additional chroma plane costs in the mode decision process, if the current block potentially contains significant color change. It improves the visual quality at very low bit-rates. The compression performance of dark720p is improved by 12.39% in speed 6. For jimred at 150 kbps, the PSNR of V component (red) increased by 0.2 dB, at the expense of about 5% increase in encoding time. Note that for sequences where the chroma components are fairly consistent, the encoding time increase is negligible. On average the rtc set compression performance is improved by 1.172% in PSNR and 1.920% in SSIM. Change-Id: Ia55b24ef23a25304f7ec9958fbf07fd6e658505c
2015-02-04vp9_dthread: remove frame_parallel_decoding_mode requirementYunqing Wang
This patch continues the work to remove frame_parallel_decoding_mode requirement in VP9 multi-threaded tile decoder. In order to do that, the frame counts associated to each thread need to be accumulated together after the frame is decoded. Change-Id: Idba1a756cedfed3c154aef52ed82c8da3bbf9e0c

2015-02-03Remove unnecessary pointer checkJohann
The original implementation had the following comment: // Ignore mv costing if mvsadcost is NULL However the current implementation does not allow for this. If x exists then nmvsadcost must not be null. This removes the only warning from -Wpointer-bool-conversion https://code.google.com/p/webm/issues/detail?id=894 Change-Id: I1a2cee340d7972d41e1bbbe1ec8dfbe917667085

2015-02-03vp9_dthread: pass frame counts to decoder functionsYunqing Wang
The current multi-threaded tile decoder requires that the videoes are encoded with frame_parallel_decoding_mode = 1. This requirement is not necessary, and is better to be removed. This patch includes the first part of the work. Change-Id: Ic7695fb3cfe13f9022582c9f0edd2aa6e2e36d28

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.
