2015-04-24Add validation of UV partition sizeYaowu Xu
For color sampling format other than 420, valid partion size in Y may not work for UV plane. This commit adds validation of UV partition size before select the partition choice. This fixes a crash for real time encoding of 422 input. Change-Id: I1fe3282accfd58625e8b5e6a4c8d2c84199751b6

(see I3a05cf1610679fed26e0b2eadd315a9ae91afdd6) For the test clip used, the decoder performance improved by ~2%. This is also an intermediate step towards adding back the mode_info streams. Change-Id: Idddc4a3f46e4180fbebddc156c4bbf177d5c2e0d

2015-04-21Modified test for auto key frame detection.paulwilkins
The existing test was triggering a lot of false positives on some types of animated material with very plain backgrounds. These were triggering code designed to catch key frames in letter box format clips. This patch tightens up the criteria and imposes a minimum requirement on the % blocks coded intra in the first pass and the ratio between the % coded intra and the modified inter % after discounting neutral (flat) blocks that are coded equally well either way. On a particular problem animation clip this change eliminated a large number of false positives including some cases where the old code selected kf several times in a row. Marginal false negatives are less damaging typically to compression and in the problem clip there are now a couple of cases where "visual" scene cuts are ignored because of well correlated content across the scene cut. Replaced some magic numbers related to this with #defines and added explanatory comments. Change-Id: Ia3d304ac60eb7e4323e3817eaf83b4752cd63ecf

2015-04-16Limit arf interval for low fpf clips.paulwilkins
This patch limits the maximum arf interval length to approximately half a second. In some low fps animations in particular the existing code was selecting an overly long interval which was hurting visual quality. For a sample problem test clip (360P animation , 15fps, ~200Kbit/s) this change also improved metrics by >0.5 db. There may be some clips where this hurts metrics a little, but the worst case impact visually is likely to be less than having an interval that is much too long. On more normal material at 24 fps or higher, the impact is likely to be nil/minimal. Change-Id: Id8b57413931a670c861213ea91d7cc596375a297

2015-04-13Force_split on 16x16 blocks in variance partition.Marco
Force split on 16x16 block (to 8x8) based on the minmax over the 8x8 sub-blocks. Also increase variance threshold for 32x32, and add exit condiiton in choose_partition (with very safe threshold) based on sad used to select reference frame. Some visual improvement near moving boundaries. Average gain in psnr/ssim: ~0.6%, some clips go up ~1 or 2%. Encoding time increase (due to more 8x8 blocks) from ~1-4%, depending on clip.

2015-04-04Enable Hadamard transform based cost estimate for all block sizesJingning Han
This commit turns on the Hadamard transform based rate distortion estimate for all block sizes in RTC coding mode. It conditionally skips the rate distortion estimation if all zero block flag is set on. No significant encoding speed change is observed. The compression performance of speed -6 is improved by 1.7% over using it only for block sizes of 32x32 and below. Change-Id: I768145e6f05c737b05b5b5f1ee674e929532cafb

2015-04-03Account for eob cost in the RTC mode decision processJingning Han
This commit accounts for the transform block end of coefficient flag cost in the RTC mode decision process. This allows a more precise rate estimate. It also turns on the model to block sizes up to 32x32. The test sequences shows about 3% - 5% speed penalty for speed -6. The average compression performance improvement for speed -6 is 1.58% in PSNR. The compression gains for hard clips like jimredvga, mmmoving, and tacomascmv at low bit-rate range are 1.8%, 2.1%, and 3.2%, respectively. Change-Id: Ic2ae211888e25a93979eac56b274c6e5ebcc21fb
