2014-01-16Inter-frame non-RD mode decisionJingning Han
This commit setups a test framework for real-time coding. It enables a light motion search for non-RD mode decision purpose. Change-Id: I8bec656331539e963c2b685a70e43e0ae32a6e9d
2014-01-06Remove avoid_frame_with_high_error from RD loopJingning Han
The feature undergoes prior assumption that the recursive partition size search from 4x4 to 64x64, hence utilizing information from small blocks to determine early termination in large block rate-distortion optimization search. The current codebase is now going from top down. The previous function might go with not properly initialized values, hence removed. Tested on pedestrian_area_1080p at 4000 kbps running under speed 2. No visible difference in runtime observed. Change-Id: I553df415c6191413762db7ae34e8790c71d8118e

2013-12-27Adaptive motion control on ref and search rangeJingning Han
This commit takes a preliminary attempt to refine the motion search control. It detects the SAD associated with mv predictor per reference frame, and based on which to determine whether the encoder wants to reduce the motion search range (if the predicted mv provides fairly small SAD), or to skip the current reference frame (if there exists another ref frame that gives much smaller SAD cost). This feature is turned on in the settings of speed 1 and above.

2013-12-12Enable adaptive pred filter type for sub8x8Jingning Han
This commit enables an adaptive prediction filter type selection for sub8x8 block sizes. In speed 1, it re-uses the filter type of collocated 8x8 block if it is tested in the rate-distortion optimization loop, for the sub8x8 blocks. Otherwise, it runs the normal test over all the three filter types. In speed 2, it re-uses the 8x8 block's prediction filter type, if available. Otherwise, force it to be EIGHTTAP.

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

2013-11-13Dual buffer encoding for intra modesJingning Han
Overall change (using dual buffer scheme for superblocks of both inter and intra modes) reduces speed 2 runtime: bluesky_1080p at 6000kbps: 263553ms -> 257441ms riverbed_1080p at 8000kbps: 233230ms -> 225308ms. Change-Id: Idf8d70f768a4b0d97b2a8506372c57b7b4022119

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
2013-11-11Enable dual buffer rd search and encoding schemeJingning Han
This commit enables the dual buffer rate-distortion optimization and encoding scheme. It stacks the original transform coefficients, quantized levels, and reconstructed coefficients, in the rate- distortion optimization search process, hence eliminates the need to re-run residual generation, forward transform, and quantization in the encoding stage.

2013-10-18Make memory alloc in pick_mode_context bsize awareJingning Han
This commit makes the buffer allocation of zcoeff_blk array in pick_mode_context block size aware. It calculates the number of 4x4 blocks in the partition and assigns the memory space accordingly. This process (and the uninitialization) is done once for each encoding pass. It allows memory copy of smaller buffer when possible. For football at 600kbps, the runtimes improve by about 1%: speed 1, 45961ms -> 45472ms speed 2, 23863ms -> 23598ms Change-Id: Id2ca24906fa89f46fa5fe742ec4b8efc2a61f877

2013-10-16Implement variance-based adaptive quantizationGuillaume Martres
This should be similar to what x264 does with --aq-mode 1. It works well with clips like parkjoy and touhou (http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv). At low bitrates, the segmentation signaling overhead may negate the benefits of this feature. (PGW) Default changed to feature OFF to allow provisional merge.

2013-10-15Re-design all-zero-coeff block index buffer useJingning Han
Use the zcoeff_blk buffer of PICK_MODE_CONTEXT to store the indexes of all-zero-coeff block of the current best mode. Remove the temporary buffer best_zcoeff_blk defined in the rate-distortion optimization loop. This improves the speed performance by about 0.5% in all speed settings.

2013-10-14Move token_cache from cost_coeffs to MACROBLOCKJingning Han
This commit moves token_cache buffer into macroblock struct, instead of defining as a local variable in cost_coeffs. This avoids repeatedly re-allocating memory space in the rate-distortion optimization loop. The runtime at speed 0 reduces: bus 2000kbps, 161692ms to 159951ms football 600kbps, 229505ms to 225821ms Change-Id: If7da6b0b6d8c5138a16271a33c4548fba33d8840
2013-10-10Re-design rate-distortion cost tracking buffersJingning Han
This commit re-designs the per transformed block rate-distortion costs tracking buffers. It removes redundant buffer usage, makes the needed context memory allocation per VP9_COMP instance and reuses the same buffer sets inside the rate-distortion optimization search loop, thereby avoiding repeatedly requiring memory space. It reduces speed 0 runtime: bus at 2000 kbps from 166763ms to 158967ms, football at 600 kbps from 246614ms to 234257ms. Both about 5% speed-up. Local tests suggest about 2% to 5% speed-up for speed 1 and 2 settings. This does not change compression performance. Change-Id: I363514c5276b5cf9a38c7251088ffc6ab7f9a4c3
2013-10-09Deprecate the use of PARTITION_INFO from encoderJingning Han
Use b_mode_info to store the inter prediction mode of sub8x8 block, in replacement of the use of partition_info. Remove redundant buffer update for partition_info. For bus_cif at 2000 kbps, this seem to make speed 0 about 1% faster. Change-Id: Id1b3be45e75a24fb4b42335ac480c23e440978f6

This commit enables forcing all coefficients zero per transformed block, when its rate-distortion cost is lower than regular coeff quantization.

2013-09-13Adaptive motion search controlJingning Han
This commit enables adaptive constraint on motion search range for smaller partitions, given the motion vectors of collocated larger partition as a candidate initial search point. It makes speed 0 runtime of bus at CIF and 2000 kbps goes from 167s down to 162s (3% speed-up), at 0.01dB performance gains. In the settings of speed 1, this makes the runtime goes from 33687 ms to 32142 ms (4.5% speed-up), at 0.03dB performance gains. Compression performance wise, it gains at speed 1: derf 0.118% yt 0.237% hd 0.203% stdhd 0.438% Change-Id: Ic8b34c67810d9504a9579bef2825d3fa54b69454

2013-08-07Use low precision 32x32fdct for encodemb in speed1Jingning Han
The low precision 32x32 fdct has all the intermediate steps within 16-bit depth, hence allowing faster SSE2 implementation, at the expense of larger round-trip error. It was used in the rate-distortion optimization search loop only. Using the low precision version, in replace of the high precision one, affects the compression performance by about 0.7% (derf, stdhd) at speed 0. For speed 1, it makes derf set down by only 0.017%.
