2013-11-18Constrain encoder motion search rangeJingning Han
Explicitly constrain the upper limit of motion search range (in the unit of full pixel) to be [-1023, +1023]. It is intended to control the effective motion search range for 4K sequences. Change-Id: I645539c70885eec0f155781f439d97d333336e88

2013-11-13Dual buffer encoding for intra modesJingning Han
Overall change (using dual buffer scheme for superblocks of both inter and intra modes) reduces speed 2 runtime: bluesky_1080p at 6000kbps: 263553ms -> 257441ms riverbed_1080p at 8000kbps: 233230ms -> 225308ms. Change-Id: Idf8d70f768a4b0d97b2a8506372c57b7b4022119

Allocate memory space of dual buffer sets that store the coeff, qcoeff, dqcoeff, and eobs. Connect the pointers of macroblock_plane and macroblockd_plane to the actual buffer in use accordingly. Change-Id: I2f0b5f482ca879fae39095013eaf8901db20a5a4

2013-10-28vp9: add TileInfoJames Zern
replaces use of cur_tile_mi_(row|col)_(start|end) by VP9_COMMON, making it less stateful and more reusable for parallel tile decoding Change-Id: I1df09382b4567a0e5f4434825d47c79afe2399be

Also avoid using floating-point operations when adaptive quantization is disabled. Change-Id: I54936d7afb661df049cdb3ecd246d04ac2a9d8d3
2013-10-16Use a separate MODE_INFO stream for each tile columnGuillaume Martres
This should make parallel tiles decoding easier to implement. Change-Id: I6226456dd11f275fa991e4a7a930549da6675915
2013-10-16Get rid of "this_mi", use "mi_8x8[0]" everywhere insteadGuillaume Martres
The only case where they were intentionally pointing to different structures was in mbgraph, and this didn't have the expected behavior because both of these pointers are used interchangeably through the code Change-Id: I979251782f90885fe962305bcc845bc05907f80c
2013-10-16Implement variance-based adaptive quantizationGuillaume Martres
This should be similar to what x264 does with --aq-mode 1. It works well with clips like parkjoy and touhou (http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv). At low bitrates, the segmentation signaling overhead may negate the benefits of this feature. (PGW) Default changed to feature OFF to allow provisional merge.

2013-10-09Deprecate the use of PARTITION_INFO from encoderJingning Han
Use b_mode_info to store the inter prediction mode of sub8x8 block, in replacement of the use of partition_info. Remove redundant buffer update for partition_info. For bus_cif at 2000 kbps, this seem to make speed 0 about 1% faster. Change-Id: Id1b3be45e75a24fb4b42335ac480c23e440978f6

2013-09-24Limit mv search range for first pass and mbgraphYaowu Xu
Both first pass and mbgraph search use block size 16x16 for motion estimation. This commit put a limit of motion vector range. The effective range allows the entire 16x16 with required subpel interpolation input to be completely outside image border, but not any further away from image border.

2013-09-22Improves constant qual, constrained qual turned onDeb Mukherjee
Adds modeled functions to decide the qp for altref frames in constant q mode similar to other functions in use in bitrate mode. Also turns on the constrained quality mode (end-usage=2) option which was turned off before. Basic testing shows the mode works in principle, to cap bitrate to the target-bitrate specified, while allowing lower bitrate depending on the cq-level specified. The mode will need to be improved over time. Results for constant quality vs bitrate control mode: derfraw300/fullderfraw: +3.0% at constant quality over bitrate control. fullstdhdraw: +4.341% stdhdraw250: +5.361% Change-Id: If5027c9ec66c8e88d33e47062c6cb84a07b1cda9

2013-09-11New mode_info_context storage -- undo revertScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of pointers to MODE_INFO structs. The MODE_INFO structs are now stored as a stream (decoder only), eliminating unnecessary copies and is a little more cache friendly. Change-Id: I031d376284c6eb98a38ad5595b797f048a6cfc0d
2013-09-10Modify encode breakout for static framesYunqing Wang
Thank Paul for the suggestions. While turning on static-thresh for static-image videos, a big jump on bitrate was seen. In this patch, we detected static frames in the video using first-pass stats. For different cases, disable encode breakout or reduce encode breakout threshold to limit the skipping. More modification need be done to break incorrect partition picking pattern for static frames while skipping happens. Change-Id: Ia25f47041af0f04e229c70a0185e12b0ffa6047f

2013-09-06Support a constant quality mode in VP9Deb Mukherjee
Adds a new end-usage option for constant quality encoding in vpx. This first version implemented for VP9, encodes all regular inter frames using the quality specified in the --cq-level= option, while encoding all key frames and golden/altref frames at a quality better than that. The current performance on derfraw300 is +0.910% up from bitrate control, but achieved without multiple recode loops per frame. The decision for qp for each altref/golden/key frame will be improved in subsequent patches based on better use of stats from the first pass. Further, the qp for regular inter frames may also be varied around the provided cq-level. Change-Id: I6c4a2a68563679d60e0616ebcb11698578615fb3
2013-09-06New mode_info_context storageScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of a pointer to a MODE_INFO struct and a "in the image" flag. The MODE_INFO structs are now stored as a stream, eliminating unnecessary copies and is a little more cache friendly. For the test clips used, the decoder performance improved by ~4.3% (1080p) and ~9.7% (720p). Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p) and 5.9% (720p).

2013-07-18Merge scale_factors and scale_factors_uv.Ronald S. Bultje
This prevents a duplicate memcpy of a 128-byte struct every time set_scale_factors() is called (which is a lot), thus leading to a decrease from 3.7 MB to 1.85 MB of struct copying per 64x64 block RD/partition loop. Overall, this decreases encoding time of the first 50 frames of bus @ 1500kbps (speed 0) from 1min5.9 to 1min4.9, i.e. about a 1.5% overall speedup. We can likely get more gains by removing the copy of the other struct (and replacing it with an indexing) as well. Change-Id: I3dceb7e79f71e6fe911b11cc994cf89a869dde7a

2013-07-12Some minor cleanups for efficiencyDeb Mukherjee
Implements some of the helper functions more efficiently with lookups rathers than branches. Modeling function is consolidated to reduce some computations. Also merged the two enums BLOCK_SIZE_TYPES and BlockSize into one because there is no need to keep them separate (even though the semantics are a little different). No bitstream or output change. About 0.5% speedup Change-Id: I7d71a66e8031ddb340744dc493f22976052b8f9f
