Merge CONFIGURE_SEGMENTATION experiment. 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.

Start to anonymize reference frames Remove lst_fb_idx, gld_fb_idx, alt_fb_idx, refresh_last_frame, refresh_golden_frame, refresh_alt_ref_frame from common. Gold/Alt are encode side conventions. From the decoder's perspective, we want to be dealing with numbered references. Updates to active_ref 2 signal mode context switches, vestigial from refresh_alt_ref_frame. This needs some clean up to make sense with increased numbers of reference frames, as well as reimplementing the swapping of alt/golden which was previously done using the buffer-to-buffer copy mechanism removed in an earlier commit.

Improved subset block search Improved the subset block search and fill. (about 3% improvement for 32 bit) Modified/merged the code in order to create vp8_read_mb_modes_mv which can decode the modes/mvs on a macroblock level. This will allow the decode loop (in the future) to decode modes/mvs on a frame, row, or mb level. Change-Id: If637d994b508792f846d39b5d44a7bf9aa5cddf3 2010-09-09 14:42:48 -04:00

Adding error-concealment to the decoder. 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). Change-Id: I5c8917b031078d79dbafd90f6006680e84a23412 2011-05-02 15:30:51 +02:00
Spatial resamping of ZEROMV predictors This patch allows coding frames using references of different resolution, in ZEROMV mode. For compound prediction, either reference may be scaled. To test, I use the resize_test and enable WRITE_RECON_BUFFER in vp9_onyxd_if.c. It's also useful to apply this patch to test/i420_video_source.h: --- a/test/i420_video_source.h +++ b/test/i420_video_source.h @@ -93,6 +93,7 @@ class I420VideoSource : public VideoSource { virtual void FillFrame() { // Read a frame from input_file. + if (frame_ != 3) if (fread(img_->img_data, raw_sz_, 1, input_file_) == 0) { limit_ = frame_; } This forces the frame that the resolution changes on to be coded with no motion, only scaling, and improves the quality of the result.
