2012-11-24Fix crash in pick_inter_mode_sb().Ronald S. Bultje
It didn't handle rd_thresh == INT_MAX, which means the reference is unavailable. Change-Id: Ie6fa8b2577437411db81a8c24e8dcdfd856a0e8d
2012-11-23Restructure vp9_decode_mb_tokens_8x8() a bit.Ronald S. Bultje
Don't declare variables if they only ever have a single value and are used only as argument to another function call; instead, just hardcode the value in the function call directly. Split out UV and Y coefficient loops for clarity. Use xd->block[].qcoeff instead of xd->qcoeff + magic to remove use of magic offset variables. Change-Id: I5b17eda1bb666c69c2b7ea957d5525cd78192e33
2012-11-23Restructure vp9_decode_mb_tokens_16x16() a bit.Ronald S. Bultje
Don't declare variables if they only ever have a single value and are used only as argument to another function call; instead, just hardcode the value in the function call directly. Also remove unneeded brackets around a code block, and remove the magic offsets 64 and 256 for chroma values in the coefficient memory block. Change-Id: I14fc14120a81ea1d6fb862674e8bf8cf6ba3d114

2012-11-20make: fix dependency generation for flat build treeJohn Koleszar
Update the fmt_deps function to use a new sed expression to convert the object file name generated by the compiler into the path-transformed name of the .o and .d files. Prior to this patch, changing a header file would not trigger an incremental build. Change-Id: I07f498a1d134577b89a72e3f1143c737b31a0636

2012-11-16Remove special-case inline detokenization in b_pred reconstruction.Ronald S. Bultje
Just like for all other block modes, b_pred tokens can be read together before starting macroblock reconstruction. This removes special cases for b_pred in decode_macroblock() and allows to make decode_coefs_4x4() static in detokenize.c. While at it, remove the redundant handling and checking of plane_type and block_index (i) in decode_coefs_4x4(). Since the function is static, and is called only from decode_mb_tokens_4x4(), we don't need to worry that the arguments ever go out of sync. Change-Id: I2d415da0b51b89d0490a6b9e24cc86363c2090f7

2012-11-16Further experimentation with the mode contextPaul Wilkins
Experiments with a larger set of contexts and some clean up to replace magic numbers regarding the number of contexts. The starting values and rate of backwards adaption are still suspect and based on a small set of tests. Added forwards adjustment of probabilities. The net result of adding the new context and forward update is small compared to the old context from the legacy find_near function. (down a little on derf but up by a similar amount for HD) HOWEVER.... with the new context and forward update the impact of disabling the reverse update (which may be necessary in some use cases to facilitate parallel decoding) is hugely reduced. For the old context without forward update, the impact of turning off reverse update (Experiment was with SB off) was Derf - 0.9, Yt -1.89, ythd -2.75 and sthd -8.35. The impact was mainly at low data rates. With the new context and forward update enabled the impact for all the test sets was no more than 0.5-1% (again most at the low end).

2012-11-16changed mv candidate search for superblocksYaowu Xu
added additional motion vectors at close neighborhood of a superblock to the list of candiate motion vectors, and removed a couple that are further away. The change helped std-hd set about .8% (all metrics) and smaller gain for derf set. Change-Id: Iaa69b98614db43420ed3fd4738d0ca5587b90045
2012-11-16Compound inter-intra experimentDeb Mukherjee
A patch on compound inter-intra prediction. In compound inter-intra prediction, a new predictor for 16x16 inter coded MBs are obtained by combining a single inter predictor with a 16x16 intra predictor, in a manner that the weight varies with distance from the top/left boundary. The current search strategy is to combine the best inter mode with the best intra mode obtained independently. Results so far: derf +0.31% yt +0.32% std-hd +0.35% hd +0.42% It is conceivable that the results would improve somewhat with a more thorough search strategy where all intra modes are searched given the best mv, or even a joint search for the best mv and the best intra mode.

2012-11-15Pack invisible frames without lengthsJohn Koleszar
Modify the decoder to return the ending position of the bool decoder and use that as the starting position for the next frame. The constant-space algorithm for parsing the appended frame lengths is O(n^2), which is a potential DoS concern if n is unbounded. Revisit the appended lengths for use as partition lengths when multipartition support is added. In addition, this allows decoding of raw streams outside of a container without additional framing information, though it's insufficient to be able to remux said stream into a container.

2012-11-15make: flatten object file directoriesJohn Koleszar
Rather than building an object file directory heirarchy matching the source tree's layout, rename the object files so that the object file name contains the path in the source file tree. The intent here is to allow two files in different parts of the source tree to have the same name and still not collide when put into an ar archive.

2012-11-15detokenize: use SEG_LVL_EOB feature consistentlyJohn Koleszar
Update decode_coefs() to break when c >= eob, since it's possible that c starts the loop from 1 and eob is 0. The loop won't terminate in that case. Add new get_eob() function to consistently clamp the eob based on the segment level EOB and the block size. It's possible to code a segment level EOB that's greater than the block size, and that leads to an out of bounds access. Change-Id: I859563b30414615cf1b30dcc2aef8a1de358c42d
