2015-03-03dc quantizer fix for 32x32 transformsDeb Mukherjee
The rounding factor needs to be scaled down by a factor of 2. Also, the quantized and dequantized coefficients are memset to 0 when dc quantizer is used. Change-Id: Ifa68bab02addbf1b83d249c5b4cbd5cda796b1cf

2014-12-04Use the RTC optimizations when in high bitdepth mode.Peter de Rivaz
Change 72193 made the encoder behave differently when configured with and without high bitdepth. This change means the same algorithm is used for both. Change-Id: I707a44a94afca773a9e0c2f7ebeeea83030257c5
2014-11-21Rework forward txfm/quantization skip system in RTC coding modeJingning Han
This commit allows more aggressive decision to skip forward transform and quantization for luma component in RTC coding mode. The chroma components remains going through the normal coding routine, since they are not included in the non-RD mode search process. It reduces the runtime cost by 2% - 10%. In speed -6, vidyo1 1000 kbps 16576 b/f, 40.281 dB, 8402 ms -> 16576 b/f, 40.323 dB, 7764 ms nik720p 1000 kbps 33337 b/f, 38.622 dB, 7473 ms -> 33299 b/f, 38.660 dB, 7314 ms dark720p 1000 kbps 33330 b/f, 39.785 dB, 13505 ms -> 33325 b/f, 39.714 dB, 13105 ms The compression performance of speed -6 is improved by 0.44% in PSNR and 1.31% in SSIM.

2014-11-18Combine fdct8x8 and quantization processJingning Han
This commit reworks the forward transform and quantization process for 8x8 block coding. It combines the two operations in a single function to save a store/load stage of the original transform coefficients. Overall the speed -6 is slightly faster (around 1% range). The compression performance of speed -6 is improved by 3.4%. Change-Id: Id6628daef123f3e4649248735ec2ad7423629387

The functions b_width_log2 and b_height_log2 only do direct table fetch. This commit unifies such use cases by using the table directly and removes these functions. Change-Id: I3103fc6ba959c1182886a2799d21b8b77c8a7b6b

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.

2014-09-11Adds high bitdepth transform functions and testsDeb Mukherjee
Adds various high bitdepth transform functions and tests. Much of the changes are related to using typedefs tran_low_t and tran_high_t for the final transform cofficients and intermediate stages of the transform computation respectively rather than fixed types int16_t/int. When vp9_highbitdepth configure flag is off, these map tp int16_t/int32_t, but when the flag is on, they map to int32_t/int64_t to make space for needed extra precision.

2014-07-08Re-design quantization process for 32x32 transform blockJingning Han
This commit enables a new quantization process for 32x32 2D-DCT transform coefficient blocks. It improves the compression performance of speed 5 by 1.4%. The overall compression gains of speed 5 due to the new quantization scheme is 4.7%. It also includes the SSSE3 implementation of the 32x32 quantization process.

2014-07-01Re-design quantization processJingning Han
This commit re-designs the quantization process for transform coefficient blocks of size 4x4 to 16x16. It improves compression performance for speed 7 by 3.85%. The SSSE3 version for the new quantization process is included. The average runtime of the 8x8 block quantization is reduced from 285 cycles -> 255 cycles, i.e., over 10% faster.

2014-06-18BITSTREAM: Handle transform size and motion vectors more logically for non-420.Alex Converse
This breaks the profile 1 bitstream. Don't force non420 uv transform size to 1/4 y size. In the 4:2:0 case the chroma corresponding to a luma block is 1/4 its size. In the 4:4:4 case chroma and luma planes are the same size. Disallowing larger transforms can result in a loss of compression efficiency and is inconsistent. For sub-8x8 blocks only average corresponding motion vectors. 4:2:0 and profile 0 behavior remains unchanged. Change-Id: I560ae07183012c6734dd1860ea54ed6f62f3cae8
2014-06-12Fast computation path for forward transform and quantizationJingning Han
This commit enables a fast path computational flow for forward transformation. It checks the sse and variance of prediction residuals and decides if the quantized coefficients are all zero, dc only, or more. It then selects the corresponding coding path in the forward transformation and quantization stage. It is currently enabled in rtc coding mode. Will do it for rd coding mode next. In speed -6, the runtime for pedestrian_area 1080p at 1000 kbps goes down from 14234 ms to 13704 ms, i.e., about 4% speed-up. Overall coding performance for rtc set is changed by -0.18%.
