2014-01-03Adding RefBuffer struct.Dmitry Kovalev
Adding RefBuffer to simplify reference buffer management. The struct has a pointer to image data and scale factors relative to the current frame. Change-Id: If38eb1491ff687cc11428aee339f3e052e2c5d9e
2013-12-19Using single struct to represent scale factors.Dmitry Kovalev
Moving back to scale_factors struct. We don't need anymore x_offset_q4 and y_offset_q4 because both values are calculated locally inside vp9_scale_mv function. Change-Id: I78a2122ba253c428a14558bda0e78ece738d2b5b
2013-12-19Call set_scaled_offsets() just before scale_mv() call.Dmitry Kovalev
Before mv scaling it is required to calculate x_offset_q4/y_offset_q4 by calling set_scaled_offsets(). Now offset configuration can not be missed because it happens just before scale_mv(). Change-Id: I7dd1a85b85811a6cc67c46c9b01e6ccbbb06ce3a

2013-12-04Cleaning up vp9_dec_build_inter_predictors_sb function.Dmitry Kovalev
Using get_plane_block_size() instead of manipulation with subsampling values, calculating all required values only once without redundant calls to b_width_log2(). Change-Id: I00303f2a0926f9c4cb17f34591adda60615f8919
2013-11-25Use separate inter predictors for enc/decJingning Han
The decoder will construct inter predictor using lazy border extension, while the encoder, going with multiple runs of motion search in the rate- distortion optimization loop for each block, does border extension at frame level. This commit makes separate the inter predictors for encoder and decoder, respectively. Change-Id: Ieca2fecba3a7201a6d64ef9f219e5d91e50559c3
2013-11-25Merge "Separate setup_scale_factor/extend_frame_borders"Jingning Han
2013-11-22Separate setup_scale_factor/extend_frame_bordersJingning Han
This commit takes out vp9_extend_frame_borders from vp9_setup_scale_factors. The refactoring is for the preparation of the use of lazy border extension at decoder. This makes it necessary to handle border extension separately at encoder/decoder. The use of vp9_extend_frame_borders will be removed, when lazy border extension is ready.

2013-11-11Removing function pointers from inter prediction.Dmitry Kovalev
Removing foreach_predicted_block_visitor and calling build_inter_predictors directly. Change-Id: I11bb3c872b99b47c2680b01b0dbcc01c558c4a2b
2013-10-29Fix x_offset_q4/y_offset_q4 calculationYunqing Wang
"<< SUBPEL_BITS" needs to be added in the calculation. Call set_scaled_offsets() to calculate x_offset_q4 and y_offset_q4. Change-Id: Ied130ea771510e918f51cd1dc3abe57f4c0962b5

2013-10-23Renaming INTERPOLATIONFILTERTYPE to INTERPOLATION_TYPE.Dmitry Kovalev
Change-Id: I1868fb75ed88bfa65c1c2ca24677d65f2894d713
2013-10-22Improve scale_factors structYunqing Wang
The ref's scale_factors are set at frame level, and then copied for each partition block. Since the struct members are mostly constant, this patch separated the constant and non-constant members, and reduced struct copying. This gave 0.5% ~ 1.4% decoder speed gain. Change-Id: I94043bf5a6995c8042da52e5c661818dfa6f6d4c
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

2013-10-03Adding vp9_get_filter_kernel() function.Dmitry Kovalev
Moving INTERPOLATIONFILTERTYPE enum and subpix_fn_table struct to vp9_filter.h. Adding convenient typedef for subpel kernels. Function vp9_setup_interp_filters() besides setting xd->subpix.filter_x & xd->subpix.filter_y has a side effect of also setting scale factors. This is not required inside decode_modes_b() because scale factors have been already set by set_ref() calls. That's why replacing vp9_setup_interp_filters() call with newly created vp9_get_filter_kernel() call. The behavior of vp9_setup_interp_filters() is unchanged (it is used from the encoder).

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
This reverts commit dae17734ece414091ba1184f7becd0aa6c0004f1 Encode crashes, leaks and increases integer overflow errors. Change-Id: I595aa2649bb8d0b6552ff91652837a74c103fda2
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).

2013-08-26Renaming BLOCK_SIZE_TYPE to BLOCK_SIZE in the common/decoder.Dmitry Kovalev
Adding temporary "typedef BLOCK_SIZE BLOCK_SIZE_TYPE" which will go away after encoder's patch. Change-Id: I06ec6a6f079401439843ec981d1496234fd7775c
2013-08-22Checking scale factors on access.Dmitry Kovalev
It is possible to have invalid scale factors and not access them during decoding. Error is reported if we really try to use invalid scale factors. Change-Id: Ie532d3ea7325ee0c7a6ada08269f804350c80fdf

2013-08-12Removing foreach_predicted_block_uv function.Dmitry Kovalev
Adding function build_inter_predictors_for_planes to build inter predictors for specified planes. This function allows to remove condition "#if CONFIG_ALPHA" and use MAX_MB_PLANE for general case. Renaming 'which_mv' local var to 'ref', and 'weight' argument to 'ref'. Change-Id: I1a97160c9263006929d38953f266bc68e9c56c7d

2013-08-06Using only one scale function in scale_factors struct.Dmitry Kovalev
Functions scale_mv_q4 and scale_mv_q3_to_q4 were almost identical except q3->q4 conversion in scale_mv_q3_to_q4. Now q3->q4 conversion happens directly in vp9_build_inter_predictor. Also adding useful constants: SUBPEL_BITS and SUBPEL_MASK. Change-Id: Ia0a6ad2ac07c45fdf95a5139ece6286c035e9639

2013-07-25General cleanups.Dmitry Kovalev
Removing unused constants, macros, and function declarations. Using ROUND_POWER_OF_TWO macro, vp9_zero, vp9_copy where possible. Moving #include from *.h to *.c. Merging for loops for motion vectors. Change-Id: Ic3bf841764a2bb177128bb3a6d7aa8f68229cd13
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
2013-07-15Change to extend full border only when neededYaowu Xu
This is a short term optimization till we work out a decoder implementation requiring no frame border extension. Change-Id: I02d15bfde4d926b50a4e58b393d8c4062d1be70f
