2012-08-20Merge "Superblock coding." into experimentalRonald S. Bultje
2012-08-20Superblock coding.Ronald S. Bultje
This commit adds a pick_sb_mode() function which selects the best 32x32 superblock coding mode. Then it selects the best per-MB modes, compares the two and encodes that in the bitstream. The bitstream coding is rather simplistic right now. At the SB level, we code a bit to indicate whether this block uses SB-coding (32x32 prediction) or MB-coding (anything else), and then we follow with the actual modes. This could and should be modified in the future, but is omitted from this commit because it will likely involve reorganizing much more code rather than just adding SB coding, so it's better to let that be judged on its own merits. Gains on derf: about even, YT/HD: +0.75%, STD/HD: +1.5%. Change-Id: Iae313a7cbd8f75b3c66d04a68b991cb096eaaba6

This doesn't affect the result, since there are no MVs coded using this entropy. It does, however, silence valgrind warnings about uninitialized variables. Change-Id: I6e21ba92df6ce5381bf58b8c349ef4373294a0b6

2012-08-14Changed to use reference mv as nearest mvYaowu Xu
The reference motion vector selected by surrounding pixels that has the best matching score is used as nearest motion vector. The change has shown consistent gain on all test sets, compression gains range from .2% to .6%. The variation is largely dependent on various other experiments on or off.

2012-08-07A bit of temporary relief on encoder slownessYaowu Xu
The commit replaces run-time initialization of cosine constants with static constant values, which provides ~30% relief on slow speed. The real solution, however will be to implement integer versions of those functions that current use float/double. Change-Id: Ie3ff1793509653d78dd1aeaf88cc6737da1bc55f

2012-08-03Replacing the 8x8 DCT with 8x8 ADST/DCT for I8x8Jingning Han
Fixed the code review comments. Under the htrans8x8 experiment the 8X8 DCT in the I8X8 mode is replaced with a combination of 8X8 ADST and DCT. Overall coding gains with the htrans8x8 experiment are: derf: 0.486 std-hd: 1.040 hd: 1.063 yt: 0.506 Note that part of the gain comes from bigger transforms (8x8 instead of 4x4) and part comes from replacing the DCT wth the ADST.

Apply 2D-DCT transform of dimension 8x8 to encode prediction residuals of I8X8 mode. Brought back block type 3 probability context model for 8x8 tokens, which is used for the coefficients of Y blocks in I8x8 modes. The coefficient costs estimate of I8X8 mode in rate-distortion is also changed appropriately.

2012-07-31Merging and bug-fix in enhanced_interp experimentDeb Mukherjee
Merged the enhanced_interp experiment. Found and fixed a bug in the include files framework, whereby certain encoder files were still using the old INTERP_EXTEND value of 3 instead of 4. The thresholds for mv range mcomp.c need a small adjustment to prevent crashes. The results are more or less unchanged. Change-Id: Iac5008390f1efc97ce1102fbb5f8989c847fb579
2012-07-30Adds support for switchable interpolation filters.Deb Mukherjee
Allows for swtiching/setting interpolation filters at the MB level. A frame level flag indicates whether to use a specifc filter for the entire frame or to signal the interpolation filter for each MB. When switchable filters are used, the encoder chooses between 8-tap and 8-tap sharp filters. The code currently has options to explore other variations as well, which will be cleaned up subsequently. One issue with the framework is that encoding is slow. I tried to do some tricks to speed things up but it is still slow. Decoding speed should not be affected since the number of filter taps remain unchanged. With the current version, we are up 0.5% on derf on average but some videos city/mobile improve by close to 4 and 2% respectively. If we did a full-search by turning the SEARCH_BEST_FILTER flag on, the results are somewhat better. The framework can be combined with filtered prediction, and I seek feedback regarding that. Rebased. Change-Id: I8f632cb2c111e76284140a2bd480945d6d42b77a
