2014-10-30Rework pred pixel buffer system in non-RD coding modeJingning Han
This commit makes the inter prediction buffer system to support hybrid partition search. It reduces the runtime of speed -5 by about 3%. No compression performance change. vidyo1 720p 1000 kbps 11831 ms -> 11497 ms nik 720p 1000 kbps 10919 ms -> 10645 ms Change-Id: I5b2da747c6395c253cd074d3907f5402e1840c36
2014-10-27Use zero motion vector in choose_partitioningJingning Han

2014-10-20Hybrid partition search for rtc coding modeJingning Han
This commit re-designs the recursive partition search scheme in rtc speed -5. It first checks if the current block is under cyclic refresh mode. If so, apply recursive partition search. Otherwise, perform sub-sampled pixel based partition selection. When the pre-selection finds the partition size should be 32x32 or above, use the partition size directly. Otherwise, apply partition search at nearby levels around the preset partition size. It is enabled in speed -5. The compression performance of rtc speed -5 is improved by 9.4%. Speed wise, the run-time goes slower from 1% to 10%. nik_720p, 1000 kbps 33220 b/f, 38.977 dB, 10109 ms -> 33200 b/f, 39.119 dB, 10210 ms vidyo1_720p, 1000 kbps 16536 b/f, 40.495 dB, 10119 ms -> 16536 b/f, 40.827 dB, 11287 ms Change-Id: I65adba352e3adc03bae50854ddaea1b421653c6c

2014-10-17Remove the dependency in token storing locationsYunqing Wang
Currently, the tokens for a tile are stored immediately after its preceding tile, which causes a dependency. This is unnecessary since we always allocate enough memory for tokens. Removing the dependency allows token writing done in parallel. This patch doesn't change encoding result. Change-Id: I7365a6e5e2c2833eb14377c37e1503c9d0f26543

2014-10-15Use rate/distortion thresholds to control non-RD partition searchJingning Han
Compare the estimated rate and distortion to the thresholds scaled according to the operating block size and determine if further split partition search will be run.

The encoding speed is 10% - 15% faster. vidyo1 720p 16545 b/f, 40.492 dB, 11475 ms -> 16535 b/f, 40.486 dB, 10100 ms nik720p 16624 b/f, 36.310 dB, 10071 ms -> 16617 b/f, 36.313 dB, 8346 ms Change-Id: Ic9197ab5761279ae55d2fb7813b2af0e0db497b8

2014-10-15Replace copy_partitioning use case with choose_partitioningJingning Han
This commit replaces the use of copy_partitioning with choose_partitioning based on the sse of subsamped pixels, which provides significantly better coding performance and runs at similar speed, as compared to copy_partitioning. It improves rtc speed 5 coding performance by 3%. Change-Id: I52d3682a12dce0147f5e52383a594fc242ca3228

2014-10-07experimental : partition using 1/8 x 1/8 imageJim Bankoski
The concept: There's too much noise in source pixels for variance and at low bitrate the reconstructed looks nothing like the source so we have problems getting good partitionings with either. This skirts the issue by using a box blur scaled down version for variance calculations. To compare against source_var_ moved keyframe to be rd based like source_var.

This commit enables the encoder to skip split partition search if the bigger block size has all non-zero quantized coefficients in low frequency area and the total rate cost is below a certain threshold. It logarithmatically scales the rate threshold according to the current block size.

This patch re-enabled the feature in Pengchong's patch (commit 12861260732a4fd5f6b667ce9d5105dc9b606eda). Originally, it was turned on while use_lastframe_partitioning > 0(not used anymore). Now it was added as a feature, and turned on while speed >= 2. As described in the original patch, this feature helps speed up the slideshows in YouTube.
