2013-12-03Moving eob array to the encoder.Dmitry Kovalev
In the decoder we don't need to save eobs, we can pass eob as an argument. That's why removing eob arrays from VP9Decompressor and TileWorkerData, and moving eob pointer from macroblockd_plane to macroblock_plane. Change-Id: I8eb919acc837acfb3abdd8319af63d1bbca8217a

2013-12-02Using local variable for token_cache.Dmitry Kovalev
The difference with the old code is that originally the whole token_cache was initialized with zeros at the beginning of decode_coefs() function. Now we set several zero values explicitly with "token_cache[scan[c]] = 0". Change-Id: I88cc5031f01d13012d1a4491739c36cb44f9401e
2013-12-02Cleaning up decode_coefs() function.Dmitry Kovalev

2013-11-13Simplifies band-getting with a static arrayDeb Mukherjee
Simplifies the code by implementing band mapping with static arrays. A lot of the code complexity introduced in a previous patch disappears. Change-Id: Ia3fac36e594fb5ad2d55ae141c58bba4c55c2d28

2013-11-12Removes conditional statements from band gettingDeb Mukherjee
Implements scan order to band map with arrays in both the encoder and decoder to remove conditional statements. Encoding seems to be about 1% faster at speed 0, tested on football. Decoding seems to be about 0.5-1% faster on a set of 25 videos. Change-Id: Idb233ca0b9e0efd790e30880642e8717e1c5c8dd
2013-11-07Merge "Miscelleneous changes in detokenize for speed"Deb Mukherjee
2013-11-06Using pd->dqcoeff instead of pd->qcoeff in the decoder.Dmitry Kovalev
It is more logical to use dqcoeff buffer to put there *dequantized* transform coefficients (inside inverse_transform_block and decode_coefs functions). Dequantization happens inside WRITE_COEF_CONTINUE macro. qcoeff buffer should be only used in the encoder for *quantized* transform coefficients. Change-Id: Ifd54bef272bbf5311ced6669c4f1079f998af5d7

2013-11-05token_cache changes in decoderDeb Mukherjee
Removes stack-alocation of token_cache in decode_coefs function Seems to achieve about 1% decode speed improvement as tested on 25 480p videos. Change-Id: I8e7eb3361fa09d9654dfad0677a6d606701fdc6e
2013-10-31Reducing the number of foreach_transformed_block() calls.Dmitry Kovalev
The change doesn't affect the bitstream. It changes the order or function calls and affects how we reconstruct intra- and inter-blocks. Speed up is about 1...1.5%. For intra-blocks: Before: for each transform block read tokens for each transform block do prediction for each transform block do inverse transform Now: for each transform block read tokens do prediction do inverse transform For inter-blocks: Before: for each transform block read tokens for each transform block do inverse transform Now: for each transform block read tokens do inverse transform Change-Id: I12a79bf1aa5a18c351b8010369bd3ff1deae1570
2013-10-21vp9 dec/com: only update frame counts when necessary (2)James Zern

* changes: Use a separate MODE_INFO stream for each tile column Get rid of "this_mi", use "mi_8x8[0]" everywhere instead Make the static_segmentation feature work again
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
2013-10-16Adding get_band_translate() function.Dmitry Kovalev

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).
