2014-12-04vp9_ethread: the tile-based multi-threaded encoderYunqing Wang
Currently, VP9 supports column-tile encoding, which allows a frame to be encoded in multiple column tiles independently. The number of column tiles are set by encoder option "--tile-columns". This provides a way to encode a frame in parallel. Based on previous set of patches, this patch implemented the tile- based multi-threaded encoder. Each thread processes one or more tiles. Usage: For HD clips: --tile-columns=2 --threads=1/2/3/4 While using 4 threads, tests showed that the encoder achieved 2.3X - 2.5X speedup at good-quality speed 3, and 2X speedup at realtime speed 5.

2014-11-24Merge "Refactored idct routines and headers"Debargha Mukherjee
2014-11-24Refactored idct routines and headersPeter de Rivaz
This change is made in preparation for a subsequent patch which adds acceleration for the highbitdepth transform functions. The highbitdepth transform functions attempt to use 16/32bit sse instructions where possible, but fallback to using the C implementations if potential overflow is detected. For this reason the dct routines are made global so they can be called from the acceleration functions in the subsequent patch.

2014-10-07experimental : partition using 1/8 x 1/8 imageJim Bankoski
The concept: There's too much noise in source pixels for variance and at low bitrate the reconstructed looks nothing like the source so we have problems getting good partitionings with either. This skirts the issue by using a box blur scaled down version for variance calculations. To compare against source_var_ moved keyframe to be rd based like source_var.

2014-10-06Add SSE2 code and unit test for VP9 denoiser.JackyChen
This SSE2 is based on VP8 denoiser's SSE2 code. In VP8, there are only 16x16 blocks in denoiser, while in VP9, there are 13 different block sizes. By adding this SSE2 code, the improvement of encoder speed is around 20%(using C code vs using SSE2 code), vary for different clips. The unit test for VP9 denoiser is to confirm that the SSE2 code is bit-exact with the C code. The unit test covers all block size. Change-Id: Ic8d8ac26db4ea40a5f146b5678a065af07eaaa3d

vp9_block_error_sse2 can only handle 16 bytes at a time but the function requires to handle a sequence of 32 bytes at a time so each 16 bytes is handled in a different register. With AVX2 optimization the 32 bytes can be handled in one register instead of two in the SSE2 The vp9_block_error was optimized by 85%.

2014-04-17add a context tree structure to encoderJim Bankoski
This patch sets up a quad_tree structure (pc_tree) for holding all of pick_mode_context data we use at any square block size during encoding or picking modes. That includes contexts for 2 horizontal and 2 vertical splits, one none, and pointers to 4 sub pc_tree nodes corresponding to split. It also includes a pointer to the current chosen partitioning. This replaces code that held an index for every level in the pick modes array including: sb_index, mb_index, b_index, ab_index. These were used as stateful indexes that pointed to the current pick mode contexts you had at each level stored in the following arrays array ab4x4_context[][][], sb8x4_context[][][], sb4x8_context[][][], sb8x8_context[][][], sb8x16_context[][][], sb16x8_context[][][], mb_context[][], sb32x16[][], sb16x32[], sb32_context[], sb32x64_context[], sb64x32_context[], sb64_context and the partitioning that had been stored in the following: b_partitioning, mb_partitioning, sb_partitioning, and sb64_partitioning. Prior to this patch before doing an encode you had to set the appropriate index for your block size ( switch statement), update it ( up to 3 lookups for the index array value) and then make your call into a recursive function at which point you'd have to call get_context which then had to do a switch statement based on the blocksize, and then up to 3 lookups based upon the block size to find the context to use. With the new code the context for the block size is passed around directly avoiding the extraneous switch statements and multi dimensional array look ups that were listed above. At any level in the search all of the contexts are local to the pc_tree you are working on (in?). In addition in most places code that used to call sub functions and then check if the block size was 4x4 and index was > 0 and return now don't preferring instead to call the right none function on the inside.
