2013-11-06Move SVC per-frame loop from sample app into libvpx properIvan Maltz
SVC multiple layer per frame encoding is invoked with vpx_svc_init and vpx_svc_encode. These interfaces are designed to be invoked from ffmpeg. Additional improvements: - make dummy frame handling a bit more explicit - fixed bug with single layer encodes - track individual frame sizes and psnrs instead of averages - parameterized quantizer, 16th scalefactors, more logging, - enabled single layer encodes to generate baseline - include new mode for 3 layer I frame with 5 total layers Change-Id: I46cfa600d102e208c6af8acd6132e0cc25cda8d4

2013-09-22Improves constant qual, constrained qual turned onDeb Mukherjee
Adds modeled functions to decide the qp for altref frames in constant q mode similar to other functions in use in bitrate mode. Also turns on the constrained quality mode (end-usage=2) option which was turned off before. Basic testing shows the mode works in principle, to cap bitrate to the target-bitrate specified, while allowing lower bitrate depending on the cq-level specified. The mode will need to be improved over time. Results for constant quality vs bitrate control mode: derfraw300/fullderfraw: +3.0% at constant quality over bitrate control. fullstdhdraw: +4.341% stdhdraw250: +5.361% Change-Id: If5027c9ec66c8e88d33e47062c6cb84a07b1cda9

2013-09-06Support a constant quality mode in VP9Deb Mukherjee
Adds a new end-usage option for constant quality encoding in vpx. This first version implemented for VP9, encodes all regular inter frames using the quality specified in the --cq-level= option, while encoding all key frames and golden/altref frames at a quality better than that. The current performance on derfraw300 is +0.910% up from bitrate control, but achieved without multiple recode loops per frame. The decision for qp for each altref/golden/key frame will be improved in subsequent patches based on better use of stats from the first pass. Further, the qp for regular inter frames may also be varied around the provided cq-level. Change-Id: I6c4a2a68563679d60e0616ebcb11698578615fb3

2013-08-21Make "good" quality 2-pass vpxenc encoding defaultDeb Mukherjee
Currently, the best quality mode in VP9 is not very well developed, and unnecessarily makes the encode too slow. Hence the command line default is changed to "good" quality. Also, the number of passes default is changed to 2 passes as well, since 1-pass encoding is not very efficient in VP9. Besides, a number of VP9 defaults are set to the currently recommended settings. With these changes, vpxenc run with --codec=vp9 --kf-max-dist=9999 --cpu-used=0 should work about the same as our borg results. Note when the --cpu-used=0 option is dropped there will be a slight difference in the output, because of a difference in the cpu-used value for the first pass. Specifically, the default when unspecified is to use cpu_used=1 for the first pass and cpu_used=0 for the second pass. But when specified, both passes will use the cpu-used value specified. Note that this also changes the default for VP8 as being "good" but other options stay unchanged. Change-Id: Ib23c1a05ae2f36ee076c0e34403efbda518c5066

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.

2013-03-13Fix pulsing issue with scalingJohn Koleszar
Updates the YV12_BUFFER_CONFIG structure to be crop-aware. The exiting width/height parameters are left unchanged, storing the width and height algined to a 16 byte boundary. The cropped dimensions are added as new fields. This fixes a nasty visual pulse when switching between scaled and unscaled frame dimensions due to a mismatch between the scaling ratio and the 16-byte aligned sizes.

2013-03-13Add VP9_GET_REFERENCE controlJohn Koleszar
This is like VP8_COPY_REFERENCE, but returns a pointer to the reference frame rather than a copy of it. This is useful when the application doesn't know what the size of the reference is, as is the case when scaling is in effect. Change-Id: I63667109f65510364d0e397ebe56217140772085
2013-03-12fix superframe index with lagged encodingJohn Koleszar
If a superframe (ARF) is generated while flushing the lagged frames at the end of the clip, the buffer pointer wasn't being properly updated to account for the size of the index, causing the next frame to overwrite the index on the previous frame.

2013-03-05Add 'superframe' indexJohn Koleszar
A 'superframe' is a group of frames that share the same PTS, but have a defined decoding order. This commit adds the ability to append an index to such a group of frames, allowing for random access to the constituent frames. This could be useful for frame-level parallelism or partial decoding in a multilayer scenario. Decoding the stream serially without such an index should work as a fallback, and VP9/TestSuperframeIndexIsOptional verifies that. Change-Id: Idff83b7560e1a7077d8fb067bfbc45b567e78b1c

Use an extra byte to explicitly indicate the scaling factors in both directions, each ranging from 0 to 15. Tested coding up to 16400x16400 dimension.

2013-02-05[WIP] Add column-based tiling.Ronald S. Bultje
This patch adds column-based tiling. The idea is to make each tile independently decodable (after reading the common frame header) and also independendly encodable (minus within-frame cost adjustments in the RD loop) to speed-up hardware & software en/decoders if they used multi-threading. Column-based tiling has the added advantage (over other tiling methods) that it minimizes realtime use-case latency, since all threads can start encoding data as soon as the first SB-row worth of data is available to the encoder. There is some test code that does random tile ordering in the decoder, to confirm that each tile is indeed independently decodable from other tiles in the same frame. At tile edges, all contexts assume default values (i.e. 0, 0 motion vector, no coefficients, DC intra4x4 mode), and motion vector search and ordering do not cross tiles in the same frame. t log Tile independence is not maintained between frames ATM, i.e. tile 0 of frame 1 is free to use motion vectors that point into any tile of frame 0. We support 1 (i.e. no tiling), 2 or 4 column-tiles. The loopfilter crosses tile boundaries. I discussed this briefly with Aki and he says that's OK. An in-loop loopfilter would need to do some sync between tile threads, but that shouldn't be a big issue. Resuls: with tiling disabled, we go up slightly because of improved edge use in the intra4x4 prediction. With 2 tiles, we lose about ~1% on derf, ~0.35% on HD and ~0.55% on STD/HD. With 4 tiles, we lose another ~1.5% on derf ~0.77% on HD and ~0.85% on STD/HD. Most of this loss is concentrated in the low-bitrate end of clips, and most of it is because of the loss of edges at tile boundaries and the resulting loss of intra predictors. TODO: - more tiles (perhaps allow row-based tiling also, and max. 8 tiles)? - maybe optionally (for EC purposes), motion vectors themselves should not cross tile edges, or we should emulate such borders as if they were off-frame, to limit error propagation to within one tile only. This doesn't have to be the default behaviour but could be an optional bitstream flag. Change-Id: I5951c3a0742a767b20bc9fb5af685d9892c2c96f
2013-01-25Adding a frame parallel decoding modeDeb Mukherjee

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.
