2013-04-16Recursive partition syntax codingJingning Han
Enable recursive partition information coding from SB64X64 down to MB16X16. The bit-stream syntax is now supporting rectangular block sizes. It starts from SB64X64 and recursively describes the partition type of the current block. If the partition type is PARTITION_NONE, the block is coded as a single unit; if it is PARTITION_HORZ or PARTITION_VERT, the block is segmented into two independently coded rectangular units, with no further partition needed; otherwise, the block is segmented into 4 square blocks. i.e., PARTITION_SPLIT case, each can be potentially further partitioned. Forward adaptive probability modeling is used for the partition information coding, conditioned on the current block size. Change-Id: I499365fb547839d555498e3bcc0387d8a3587d87
2013-04-15Initial addition of multiple ARF framesAdrian Grange
This is work-in-progress, it implements multiple ARF encoding behind an experimental flag. It adds the ability to insert multiple ARF frames into a single ARF group. This patch implements the reordering of the coded frames, and implements a fixed-length coding pattern. It applies a fixed quantizer strategy based on where the frame is in the coding sequence. Further work to modify the rate control strategy is ongoing and will be submitted via a set of future patches. In this first step, each ARF group is recursively bisected and an ARF frame added at that position in the sequence. The recursion continues until ARF frames are within MIN_GF_INTERVAL frames. The code sits behind the "multiple-arf" experimental flag ("CONFIG_MULTIPLE_ARF"). The experimental flag "oneshotq" ("CONFIG_ONESHOTQ") also needs to be enabled for this patch to work correctly.

2013-03-07Coding con-zero count rather than EOB for coeffsDeb Mukherjee
This patch revamps the entropy coding of coefficients to code first a non-zero count per coded block and correspondingly remove the EOB token from the token set. STATUS: Main encode/decode code achieving encode/decode sync - done. Forward and backward probability updates to the nzcs - done. Rd costing updates for nzcs - done. Note: The dynamic progrmaming apporach used in trellis quantization is not exactly compatible with nzcs. A suboptimal approach has been used instead where branch costs are updated to account for changes in the nzcs. TODO: Training the default probs/counts for nzcs Change-Id: I951bc1e22f47885077a7453a09b0493daa77883d
2013-03-06Added stricter Q control flag.Paul Wilkins
Added a variant of the one shot maxQ flag for two pass that forces a fixed Q for the normal inter frames. Disabled by default. Also small adjustment to the Bits per MB estimation. Change-Id: I87efdfb2d094fe1340ca9ddae37470d7b278c8b8
2013-02-25Minor rate control refactoring and experiments.Paul Wilkins
Some minor refactoring code relating to estimates of bits per MB at a given Q and estimating the allowed Q range. Most of the changes here were included in a previous commit. This commit seeks to separate out the refactoring from more the material changes. Two #define control flags have been added for experimentation. ONE_SHOT_Q_ESTIMATE force the two pass encoder to use its initial Q range estimate for the whole clip even if this results in a miss on the target data rate. In effect this tightens the Q range seen at the expense of rate control accuracy. DISABLE_RC_LONG_TERM_MEM is a related flag that disables the long term memory in the rate control. Local adjustments are still made to try and better hit the rate target on a per frame basis but the impact of rate control misses is not propagated to the remainder of the clip. This means that for example an overshoot early on will not cause frames later in the clip to be starved of bits. Again the result of this relaxation amy be less rate control accuracy especially on short clips. The flags are disabled by default for now. Change-Id: I7482f980146d8ea033b5d50cc689f772e4bd119e

2013-02-22Experimental removal of over quant codePaul Wilkins

2013-01-23Adds an error-resilient mode with testDeb Mukherjee
Adds an error-resilient mode where frames can be continued to be decoded even when there are errors (due to network losses) on a prior frame. Specifically, backward updates are turned off and probabilities of various symbols are reset to defaults at the beginning of each frame. Further, the last frame's mvs are not used for the mv reference list, and the sorting of the initial list based on search on previous frames is turned off as well. Also adds a test where an arbitrary set of frames are skipped from decoding to simulate errors. The test verifies (1) that if the error frames are droppable - i.e. frame buffer updates have been turned off - there are no mismatch errors for the remaining frames after the error frames; and (2) if the error-frames are non droppable, there are not only no decoding errors but the mismatch PSNR between the decoder's version of the post-error frames and the encoder's version is at least 20 dB.

2013-01-18Use alt-ref frame context for keyframesJohn Koleszar
This matches the behavior prior to generalizing the frame context selection, and intuitively makes sense in that the first forward ref is immediately after the keyframe, so it's quality is improved a bit by using the keyframe's entropy context rather than the default. Change-Id: Ia82cef79382b9d8cfafdc44ba0533d4dc3e44053
2013-01-16Generalize and increase frame coding contextsJohn Koleszar
Previously there were two frame coding contexts tracked, one for normal frames and one for alt-ref frames. Generalize this by signalling the context to use in the bitstream, rather than tieing it to the alt ref refresh bit. Also increase the number of contexts available to 4, which may be useful for temporal scalability. Change-Id: I7b66daaddd55c535c20cd16713541fab182b1662
2013-01-16Start to anonymize reference framesJohn Koleszar
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.
