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.

2015-01-26Adjust active maxq for GF groups.Paul Wilkins
Currently disabled by default: enabled using #define GROUP_ADAPTIVE_MAXQ In this patch the active max Q is adjusted for each GF group based on the vbr bit allocation and raw first pass group error. This will tend to give a lower q for easy sections and a higher value for very hard sections. As such it is expected to improve quality in some of the easier sections where quality issues have been reported. This change tends to hurt overall psnr but help average psnr. SSIM also shows a small gain. Average results for derf, yt, std-hd and yt-hd test sets were as follows (%change for average psnr, overal psnr and ssim):- derf +0.291, - 0.252, -0.021 yt +6.466, -1.436, +0.552 std-hd +0.490, +0.014, +0.380 yt-hd +5.565, - 1.573, +0.099 Change-Id: Icc015499cebbf2a45054a05e8e31f3dfb43f944a

2015-01-22Modify variance partition selection for low resolutions.Marco
For low spatial resolutions: bias partittion selection to smaller block sizes, and base the variance computation on 4x4 down-sampling. Also move the threshold computations into the choose_partitioning, so they are computed once for each sb block. On low-res clips (RTC_derf) PSNR/SSIMetrics increase by about 4-5%. No change for resolutions above CIF. Change-Id: I93f8ff742c8044786977bb6e31dcf8efda6dd1b0

2015-01-21Bug when last group before forced key frame is short.Paul Wilkins
Just before a forced key frame we often get a foreshortened arf/gf group. In such a case, we do not want to update rc->last_boosted_qindex, which is used to define the Q range for the forced key frame itself. This gives a small average metrics gain for the YT and YT-HD sets (eg. YT SSIM +0.141%). Change-Id: Ie06698bc4f249e87183b8f8fb27ff8f3fde216d9

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).
