Facilitates encoding tiles in parallel. BUG=webm:1309 Change-Id: I614a5a492c30b6773c30e7294cd6a6f456e02ab4
2016-09-19Code class0 using vpx_read() / vpx_write().Nathan E. Egge
The vp9_mv_class0_tree is a balanced tree with two leafs and can simply be coded as a boolean with probability class0[0]. Change-Id: If294dac825a5f945371092c74aa8e3f84cd962b6 (cherry picked from commit be8a8ab62ebdd111c6f2e9a33b15630570671eba)

2015-06-29VP9: Move ref_mvs[][] and mode_context[] from MB_MODE_INFOScott LaVarnway
to MB_MODE_INFO_EXT. This saves 36 bytes per 8x8 area for both the decoder and encoder. (encoder has two MODE_INFO buffers) Change-Id: If006abb2224acaf326df3c2be09e77e967662107

2015-04-21Revert "Remove mi_grid_* structures."Scott LaVarnway
(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
2014-11-24vp9_ethread: modify VP9_COMP structureYunqing Wang
This patch modified struct VP9_COMP. Created a struct ThreadData to include data that need to be copied for each thread. In multiple thread case, one thread processes one tile. all threads share one copy of VP9_COMP, (refer to VP9_COMP *cpi in the code) but each thread has its own copy of ThreadData, (refer to ThreadData *td in the code). Therefore, within the scope of encode_tiles(), both cpi and td need to be passed as function parameters. In single thread case, the FRAME_COUNTS pointer in ThreadData points to "counts" in VP9_COMMON. Change-Id: Ib37908b2d8e2c0f4f9c18f38017df5ce60e8b13e
2014-10-22vp9_ethread: allocate frame contexts outside VP9_COMMON structYunqing Wang
This patch allocated frame contexts outside VP9_COMMON. This allows multiple threads to share the same copy of frame contexts, and reduces the overhead. It also guarantees the correct update of these contexts during bitstream packing. This patch doesn't change encoding result. Change-Id: Ic181a2460b891d1d587278a6d02d8057b9dbd353
2014-09-19Remove mi_grid_* structures.hkuang
mi_grid_* are arrays of pointer to pointer. They save the pointers that point to the MIs in cm->mi. But they are unnecessary and complicated. The original goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer inside MODE_INFO_t, same goal could be achieved. This commit totally removes the mi_grid_* structures. But there are still many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit will do on-demand MODE_INFO_t allocation in order to save these memories.

Removing special case handling from vp9_tree_probs_from_distribution(), tree_merge_probs(), and vp9_tokens_from_tree_offset() functions. Replacing inter_mode_offset() function with macro INTER_OFFSET which is used now for vp9_inter_mode_tree definition. Change-Id: Iff75a1499d460beb949ece543389c8754deaf178
2013-11-01Removing 'new' probability calculation from convert_distribution().Dmitry Kovalev
We don't have to calculate 'new' probability in convert_distribution() because it is enough to calculate only 'new' counters which could be used to calculate probability if necessary. That's why removing a lot of unused temporary probability arrays and reducing number of get_binary_prob() calls. Change-Id: I4e14eb7203d1ace61bbddefd6b9b6326be83ba63
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

2013-09-11New 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

2013-09-06New 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).
