2011-07-08New loop filter interfaceAttila Nagy
Separate simple filter with reduced no. of parameters. MB filter level picking based on precalculated table. Level table updated for each frame. Inside and edge limits precalculated and updated just when sharpness changes. HEV threshhold is constant. ARM targets use scalars and others vectors. Change works only with --target=generic-gnu All other targets have to be updated! Change-Id: I6b73aca6b525075b20129a371699b2561bd4d51c

2011-06-30Bug fix in motion vector limit calculationYunqing Wang
Motion vector limits are calculated using right shifts, which could give wrong results for negative numbers. James Berry's test on one clip showed encoder produced some artifacts. This change fixed that. Change-Id: I035fc02280b10455b7f6eb388f7c2e33b796b018

2011-06-29Merge "Change to arf boost calculation."Paul Wilkins
2011-06-29Change to arf boost calculation.Paul Wilkins
In this commit I have added an experimental function that tests prediction quality either side of a central position to calculate a suggested boost number for an ARF frame. The function is passed an offset from the current position and a number of frames to search forwards and backwards. It returns a forward, backward and compound boost number. The new code can be deactivated using #define NEW_BOOST 0 In its current default state the code searches forwards and backwards from the proposed position of the next alt ref. The the old code used a boost number calculated by scanning forward from the previous GF up to the proposed alt ref frame position. I have also added some code to try and prevent placement of a gf/arf where there is a brief flash. Change-Id: I98af789a5181148659f10dd5dd2ff2d4250cd51c

2011-06-28New ways of passing encoded data between encoder and decoder.Stefan Holmer
With this commit frames can be received partition-by-partition from the encoder and passed partition-by-partition to the decoder. At the encoder-side this makes it easier to split encoded frames at partition boundaries, useful when packetizing frames. When VPX_CODEC_USE_OUTPUT_PARTITION is enabled, several VPX_CODEC_CX_FRAME_PKT packets will be returned from vpx_codec_get_cx_data(), containing one partition each. The partition_id (starting at 0) specifies the decoding order of the partitions. All partitions but the last has the VPX_FRAME_IS_FRAGMENT flag set. At the decoder this opens up the possibility of decoding partition N even though partition N-1 was lost (given that independent partitioning has been enabled in the encoder) if more info about the missing parts of the stream is available through external signaling. Each partition is passed to the decoder through the vpx_codec_decode() function, with the data pointer pointing to the start of the partition, and with data_sz equal to the size of the partition. Missing partitions can be signaled to the decoder by setting data != NULL and data_sz = 0. When all partitions have been given to the decoder "end of data" should be signaled by calling vpx_codec_decode() with data = NULL and data_sz = 0. The first partition is the first partition according to the VP8 bitstream + the uncompressed data chunk + DCT address offsets if multiple residual partitions are used.

2011-06-23Copy macroblock data to a buffer before encoding itYunqing Wang
I got this idea from Pascal (Thanks). Before encoding a macroblock, copy it to a 16x16 buffer, and then read source data from there instead. This will help keep the source data in cache, and help with the performance. Change-Id: Id05f4cb601299150511d59dcba0ae62c49b5b757

2011-06-23Revert "Reduce overshoot in 1 pass rate control"John Koleszar
This reverts commit 212f6183739d448ad5fa2ccf1b4edd30829b2806. Further testing shows that the overshoot accumulation/damping is too aggressive on some clips. Allowing the accumulated overshoot to decay and limiting to damping to golden frames shows some promise. But some clips show significant overshoot in the buffer window, so I think this still needs work. Change-Id: Ic02a9ca34f55229f9cc04786f4fab54cdc1a3ef5

2011-06-20adjusting the calculation of errorperbitYaowu Xu
RDMULT/RDDIV defines a bit worth of distortion in term of sum squared difference. This has also been used as errorperbit in subpixel motion search, where the distortions computed as variance of the difference. The variance of differences is different from sum squared differences by amount of DC squared. Typically, for inter predicted MBs, this difference averages around 10% between the two distortion, so this patch introduces a 110% constant in deriving errorperbit from RDMULT/RDDIV. Test on CIF set shows small but positive gain on overall PSNR (.03%) and SSIM (.07%), overall impact on average PSNR is 0. Change-Id: I95425f922d037b4d96083064a10c7cdd4948ee62

2011-06-17Remove unnecessary bounds checking in motion searchYunqing Wang
The starting points are always within the limits, and bounds checking on these points is not needed. For speed < 5, the encoded result changes a little because different treatment is taken while starting point equals the bounds. Change-Id: I09a402d310f51e305a3519f1601b1d17b05c6152
