2012-08-03enable interleaved decoding of mode and mvYaowu Xu
Previouly, the decoding of mode and motion vector are done a per frame basis followed by residue decoding and reconstuction. The commit added the option to allow decoder to interleave the decoding of mode and mvs with the residue decoding on a per MB basis. Change-Id: Ia5316f4a7af9ba7f155c92b5a6fc97201b653571

2011-12-06Dual 16x16 inter prediction.Ronald S. Bultje
This patch introduces the concept of dual inter16x16 prediction. A 16x16 inter-predicted macroblock can use 2 references instead of 1, where both references use the same mvmode (new, near/est, zero). In the case of newmv, this means that two MVs are coded instead of one. The frame can be encoded in 3 ways: all MBs single-prediction, all MBs dual prediction, or per-MB single/dual prediction selection ("hybrid"), in which case a single bit is coded per-MB to indicate whether the MB uses single or dual inter prediction. In the future, we can (maybe?) get further gains by mixing this with Adrian's 32x32 work, per-segment dual prediction settings, or adding support for dual splitmv/8x8mv inter prediction. Gain (on derf-set, CQ mode) is ~2.8% (SSIM) or ~3.6% (glb PSNR). Most gain is at medium/high bitrates, but there's minor gains at low bitrates also. Output was confirmed to match between encoder and decoder. Note for optimization people: this patch introduces a 2nd version of 16x16/8x8 sixtap/bilin functions, which does an avg instead of a store. They may want to look and make sure this is implemented to their satisfaction so we can optimize it best in the future. Change-ID: I59dc84b07cbb3ccf073ac0f756d03d294cb19281
2011-11-15Merge CONFIGURE_SEGMENTATION experiment.Paul Wilkins
Removal of CONFIGURE_SEGMENTATION ifdefs. Removal of legacy support code fo the old coding mechanism. Use local reference "xd" for MACROBLOCKD structure in encode_frame_to_data_rate() Moved call to choose_segmap_coding_method() out of encode loop as the cost of segmentation is not properly accounted in the loop anyway. If this is desirable in the future it can be moved back. The use of this function to do all the analysis and set the probabilities also removes the need to track segment useage in threading code.

2011-08-12Disable error concealment until first key frame is decodedStefan Holmer
When error concealment is enabled the first key frame must be successfully received before error concealment is activated. Error concealment will be activated when the delta following delta frame is received. Also fixed a couple of bugs related to error tracking in multi-threading. And avoiding decoding corrupt residual when we have multiple non-resilient partitions. Change-Id: I45c4bb296e2f05f57624aef500a874faf431a60d

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.

2011-05-19Adding error-concealment to the decoder.Stefan Holmer
The error-concealer is plugged in after any motion vectors have been decoded. It tries to estimate any missing motion vectors from the motion vectors of the previous frame. Intra blocks with missing residual are replaced with inter blocks with estimated motion vectors. This feature was developed in a separate sandbox (sandbox/holmer/error-concealment).

2010-11-11Use of temporal context for encoding delta updates.Suman Sunkara
- Used three probability approach for temporal context as follows: P0 - probability of no change if both above and left not changed P1 - probability of no change if one of above and left has changed P2 - probability of no change if both above and left have changed In addition, a 1 bit/frame has been used to decide whether to use temporal context or to encode directly. The cost of using both the schemes is calculated ahead and the temporal_update flag is set if the cost of using temporal context is lower than encoding the segment ids directly. This approach has given around 20% reduction in cost of bits needed to encode segmentation ids. Change-Id: I44a5509599eded215ae5be9554314280d3d35405
2010-10-27Eliminate more warnings.Timothy B. Terriberry
This eliminates a large set of warnings exposed by the Mozilla build system (Use of C++ comments in ISO C90 source, commas at the end of enum lists, a couple incomplete initializers, and signed/unsigned comparisons). It also eliminates many (but not all) of the warnings expose by newer GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite without checking the return values). There are a few spurious warnings left on my system: ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used uninitialized in this function gcc seems to be unable to figure out that the value shortcut doesn't change between the two if blocks that test it here. ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned expression >= 0 is always true ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned expression >= 0 is always true This is true, so far as it goes, but it's comparing against an enum, and the C standard does not mandate that enums be unsigned, so the checks can't be removed.
