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
2013-10-21Moving allow_high_precision_mv from MACROBLOCKD to VP9_COMMON.Dmitry Kovalev
This value is a global frame-level flag, not a macroblock-level. Change-Id: Ie8c5790a931150741c2167c00c3e3dd2cf26744d
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
2013-10-03Change b_mode_info definition from union to structJingning Han
This commit defines b_mode_info as a struct type. This will allow us to further remove the use of PARTITION_INFO in the encoding process. Change-Id: I975b0f7d557b5e0f66545a61b472def76b671cce

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
2013-09-09Revert "New mode_info_context storage"James Zern

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).

* changes: Restore SSSE3 subpixel filters in new convolve framework Convert subpixel filters to use convolve framework Add 8-tap generic convolver
2013-02-05Convert subpixel filters to use convolve frameworkJohn Koleszar
Update the code to call the new convolution functions to do subpixel prediction rather than the existing functions. Remove the old C and assembly code, since it is unused. This causes a 50% performance reduction on the decoder, but that will be resolved when the asm for the new functions is available. There is no consensus for whether 6-tap or 2-tap predictors will be supported in the final codec, so these filters are implemented in terms of the 8-tap code, so that quality testing of these modes can continue. Implementing the lower complexity algorithms is a simple exercise, should it be necessary. This code produces slightly better results in the EIGHTTAP_SMOOTH case, since the filter is now applied in only one direction when the subpel motion is only in one direction. Like the previous code, the filtering is skipped entirely on full-pel MVs. This combination seems to give the best quality gains, but this may be indicative of a bug in the encoder's filter selection, since the encoder could achieve the result of skipping the filtering on full-pel by selecting one of the other filters. This should be revisited. Quality gains on derf positive on almost all clips. The only clip that seemed to be hurt at all datarates was football (-0.115% PSNR average, -0.587% min). Overall averages 0.375% PSNR, 0.347% SSIM. Change-Id: I7d469716091b1d89b4b08adde5863999319d69ff
2013-02-05Change definition of NearestMV.Paul Wilkins

2013-01-23Adds an error-resilient mode with testDeb Mukherjee
Adds an error-resilient mode where frames can be continued to be decoded even when there are errors (due to network losses) on a prior frame. Specifically, backward updates are turned off and probabilities of various symbols are reset to defaults at the beginning of each frame. Further, the last frame's mvs are not used for the mv reference list, and the sorting of the initial list based on search on previous frames is turned off as well. Also adds a test where an arbitrary set of frames are skipped from decoding to simulate errors. The test verifies (1) that if the error frames are droppable - i.e. frame buffer updates have been turned off - there are no mismatch errors for the remaining frames after the error frames; and (2) if the error-frames are non droppable, there are not only no decoding errors but the mismatch PSNR between the decoder's version of the post-error frames and the encoder's version is at least 20 dB.

2012-12-05Change to MV reference search.Paul Wilkins
This patch reduces the cpu cost of the MV ref search by only allowing insert for candidates that would be in the current top 4. This could alter the outcome and slightly favors near candidates which are tested first but also limits the worst case loop count to 4 and means in many cases it will drop out and not happen.
