2013-08-09Renaming BLOCK_SIZE_TYPES constant to BLOCK_SIZES.Dmitry Kovalev
There will be another change set to rename BLOCK_SIZE_TYPE enum to BLOCK_SIZE. Change-Id: I8d1dfc873d6186fa5e554262f5169e929978085e
2013-08-09Moving loopfilter struct to VP9_COMMON.Dmitry Kovalev
Loop filter configuration doesn't belong to macroblock, so moving it from MACROBLOCKD to VP9_COMMON. Also moving the declaration of loopfilter struct from vp9_blockd.h to vp9_loopfilter.h. Change-Id: I4b3e34be9623b47cda35f9b1f9951f8c5b1d5d28
2013-08-09Bug fix: call set_offsets before rd_auto_partition_rangeScott LaVarnway
The set_offsets call is necessary inorder to set the mode_info_context ptr correctly. Change-Id: I644910cc5bacc50ee9cd78458843274ad8ee636d
2013-08-08Moved fast motion search level decision to functionAdrian Grange
Moving this block of code into a function makes the code easier to read and change. Change-Id: If4ede570cce1eab1982b188c4d3e4fd3d4db236e
2013-08-08Simplify & fix potential bug in rd_pick_partitionAdrian Grange
Different partitionings were not being evaluated against best_rd and there were unnecessary calls to RDCOST. This could have resulted in a non-optimal partioning being selected. I simplified the variables used to track the rate, distortion and RD values throughout the function. Change-Id: Ifa7085ee80d824e86791432a5bc6d8fea5a3e313
2013-08-07Use low precision 32x32fdct for encodemb in speed1Jingning Han
The low precision 32x32 fdct has all the intermediate steps within 16-bit depth, hence allowing faster SSE2 implementation, at the expense of larger round-trip error. It was used in the rate-distortion optimization search loop only. Using the low precision version, in replace of the high precision one, affects the compression performance by about 0.7% (derf, stdhd) at speed 0. For speed 1, it makes derf set down by only 0.017%.

2013-08-06Inlining vp9_get_pred_probs_switchable_interp function.Dmitry Kovalev
There was no benefit having this function. For example, inside read_switchable_filter_type switchable filter context was calculated twice. Change-Id: I79cd5bf95cbc0f6d8bf91a2e32289e01b18dcff1

2013-08-05Add variance based mode/skippingDeb Mukherjee
Adds a speed feature to skip all intra modes other than DC_PRED if the source variance is small. This feature is made part of speed 1 and up. Results on derf300: psnr -0.07%, speedup about 1-2% Also uses the source variance to fine-tune the early termination criteria when FLAG_EARLY_TERMINATE is on. This feature is made part of speed 2 and up. Results on derf300: psnr -0.52%, speedup about 5-7% Change-Id: I59e38aa836557cfa5405ae706fc64815cbfe4232

2013-08-05Changing the order switchable filter enum constants.Dmitry Kovalev
This changeset allows to remove vp9_switchable_interp and vp9_switchable_interp_map arrays and make code much clear. Actually we still have to use these mapping but only inside read_interp_filter_type and write_interp_filter_type functions. Change-Id: I4026c6f8c4acefba6c81421b7bacbaa52cc45f50

2013-07-26Auto min and max partition size experiment.Paul Wilkins
Speed feature experiment to set an upper and lower partition size limit based on what has been seen in spatial neighbors. This seems to gives quite reasonable speed gains in local (10-15%) and when used with speed 0 the losses are small (0.25% derf, 0.35% stdhd). However, for now I am only enabling it on speed 1 as there may be clashes with the existing temporal partition selection in speed 2. Using a tighter min / max around the range derived from the neighbors increases speed further but at the cost of a bigger quality loss. However, I think this spatial method could be combined with data from either the last frame or a variance method (or both) to refine the range of minimum and maximum partition size. I.e. consider the min and max from spatial and temporal neighbors and the variance recommendation. Change-Id: I1b96bf8b84368d6aad0c7aa600fe141b4f07435f
2013-07-25Merge "Add encoding option --static-thresh"Yunqing Wang
2013-07-25Add encoding option --static-threshYunqing Wang
This option exists in VP8, and it was rewritten in VP9 to support skipping on different partition levels. After prediction is done, we can check if the residuals in the partition block will be all quantized to 0. If this is true, the skip flag is set, and only prediction data are needed in reconstruction. Based on DCT's energy conservation property, the skipping check can be estimated in spatial domain. The prediction error is calculated and compared to a threshold. The threshold is determined by the dequant values, and also adjusted by partition sizes. To be precise, the DC and AC parts for Y, U, and V planes are checked to decide skipping or not. Test showed that 1. derf set: when static-thresh = 1, psnr loss is 0.666%; when static-thresh = 500, psnr loss is 1.162%; 2. stdhd set: when static-thresh = 1, psnr loss is 1.249%; when static-thresh = 500, psnr loss is 1.668%; For different clips, encoding speedup range is between several percentage and 20+% when static-thresh <= 500. For example, clip bitrate static-thresh psnr time akiyo(cif) 500 0 48.923 5.635s(50f) akiyo 500 500 48.863 4.402s(50f) parkjoy(1080p) 4000 0 30.380 77.54s(30f) parkjoy 4000 500 30.384 69.59s(30f) sunflower(1080p) 4000 0 44.461 85.2s(30f) sunflower 4000 500 44.418 78.1s(30f) Higher static-thresh values give larger speedup with larger quality loss.
