2017-02-21vp9: Incorporate source sum_diff into non-rd partition thresholds.Marco
Increase the variance partition thresholds for superblocks that have low sum-diff (from source analysis prior to encoding frame). Use it for now only for speed >= 7 or for denoising on. Small change on metrics for rtc set: less than ~0.1 avgPNSR decrease on RTC set, for both speed 7 and 8. Change-Id: I38325046ebd5f371f51d6e91233d68ff73561af1
2017-02-15Row based multi-threading of encoding stageRanjit Kumar Tulabandu
(Yunqing Wang) This patch implements the row-based multi-threading within tiles in the encoding pass, and substantially speeds up the multi-threaded encoder in VP9. Speed tests at speed 1 on STDHD(using 4 tiles) set show that the average speedups of the encoding pass(second pass in the 2-pass encoding) is 7% while using 2 threads, 16% while using 4 threads, 85% while using 8 threads, and 116% while using 16 threads.

2015-05-27Refactor set_vbp_thresholds.Marco
Break out the setting of the block variance split thresholds, since they are locally modified, e.g., based on local/segment qp. No change in performance. Change-Id: I0a3238e6dab05140657539fc4bd27ac5ff7a554e

This patch fixed 2 reported Tsan errors while running VP9 real-time encoder. Change-Id: Ib0278fe802852862c3ce87c4a500e544d7089f67
2015-04-02Set vbp thresholds for aq3 boosted blocksYunqing Wang
The vbp thresholds are set seperately for boosted/non-boosted superblocks according to their segment_id. This way we don't have to force the boosted blocks to split to 32x32. Speed 6 RTC set borg test result showed some quality gains. Overall PSNR: +0.199%; Avg PSNR: +0.245%; SSIM: +0.802%. No speed change was observed. Change-Id: I37c6643a3e2da59c4b7dc10ebe05abc8abf4026a
2015-02-10Move computation up to frame levelYaowu Xu
This is to avoid redo the same calculation repeatly, and also allow easier adjustments for further experiments. This commit shall have no effect on quality/compression. Change-Id: I4460acf5c808ff5518da18d21e002c5da58af857
2014-12-04vp9_ethread: the tile-based multi-threaded encoderYunqing Wang
Currently, VP9 supports column-tile encoding, which allows a frame to be encoded in multiple column tiles independently. The number of column tiles are set by encoder option "--tile-columns". This provides a way to encode a frame in parallel. Based on previous set of patches, this patch implemented the tile- based multi-threaded encoder. Each thread processes one or more tiles. Usage: For HD clips: --tile-columns=2 --threads=1/2/3/4 While using 4 threads, tests showed that the encoder achieved 2.3X - 2.5X speedup at good-quality speed 3, and 2X speedup at realtime speed 5.

2014-06-30Decide the partitioning threshold from the variance histogramYunqing Wang
Before encoding a frame, calculate and store each 16x16 block's variance of source difference between last and current frame. Find partitioning threshold T for the frame from its variance histogram, and then use T to make partition decisions. Comparing with fixed 16x16 partitioning, rtc set test showed an overall psnr gain of 3.242%, and ssim gain of 3.751%. The best psnr gain is 8.653%. The overall encoding speed didn't change much. It got faster for some clips(for example, 12% speedup for vidyo1), and a little slower for others. Also, a minor modification was made in datarate unit test.

2014-04-08Use source frame difference to make partition decisionYunqing Wang
Calculate the difference variance between last source frame and current source frame. The variance is calculated at 16x16 block level. The variances are compared to several thresholds to decide final partition sizes. An adaptive strategy is implemented to decide using SOURCE_VAR_BASED_PARTITION or FIXED_PARTITION based on motions in the video. The switching test is done once every search_type_check_frequency frames. The selection of source_var_thresh needs to be investigated further later. RTC set Borg test showed 0.424% overall psnr gain, and 0.357% ssim gain. For clips with large enough static area, the encoding speedup is around 2% to 15%.
