2014-02-06Layer based rate control for CBR mode.Marco Paniconi
This patch adds a buffer-based rate control for temporal layers, under CBR mode. Added vpx_temporal_scalable_patters.c encoder for testing temporal layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns). Updated datarate unittest with tests for temporal layer rate-targeting. Change-Id: I8900a854288b9354d9c697cfeb0243a9fd6790b1

2013-12-27Removing vpx_codec_vp9x_cx and internal experimental flag.Dmitry Kovalev
vpx_codec_vp9x_cx is not used internally. Experimental flag from vp9_extracfg is also not really used. YUV 4:4:4 just works after these changes (you have to specify --profile=1 for the encoder). Change-Id: Ib1c8461d0d19d159827e005efe868f891eea0140

2013-12-04Modified spatial scalable encoder & unit testsAdrian Grange
Modifications to the spatial scalable encoder to match changes made to the scaling code in the decoder. In particular, the use of a dummy first frame was removed now that the decoder is able to handle a smaller first frame. SvcTest.FirstFrameHasLayers unit test re-enabled. Change-Id: Ic2e91fbe4eadf95895569947670d36d68abaf458
2013-11-22Fix decoder to handle display size correctlyAdrian Grange
The decoder ignored the display width & height specified in the frame header. This patch adds a control, VP9D_GET_DISPLAY_SIZE, to allow the application to obtain the display width and height from the frame header. vpxdec has been modified to scale the output frame to this size. Should the request for the display size fail vpxdec will use the native width and height of the raw decoded frame instead. Change-Id: I25db04407426dac730263720c75a7dd6400af68a

2013-11-06Merge "Move SVC per-frame loop from sample app into libvpx proper"Ivan Maltz
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

2013-09-06Support 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

2013-06-17Fixing compilation error on Mac OS.Dmitry Kovalev
The error happened because of vp8_decrypt_cb typedef redefinition in both treereader.h and vp8dx.h. Removing typedef from vp8dx.h in favor of raw function pointer declaration. Change-Id: I0266eb341ce433d40caf0abf8748694d505ee786
2013-06-17Change the encryption feature to use a callback for decryption.Jeff Petkau
This allows code calling the library can choose an arbitrary encryption algorithm. Decoder control parameter VP8_SET_DECRYPT_KEY is renamed to VP8D_SET_DECRYPTOR, and now takes an small config struct instead of just a byte array. Change-Id: I0462b3388d8d45057e4f79a6b6777fe713dc546e
2013-05-06Y4M input support for 4:2:2, 4:4:4, 4:4:4:4John Koleszar
Adds a new experiment CONFIG_NON420 that allows other chroma subsamplings to be passed to the codec. This commit allows the data to be passed from a y4m input file through vpxenc to the codec, where they're currently rejected. Later commits will finish support for this inside the codec. Change-Id: Ib3aac604d8cad9e24cef395fa1067f16ba7e8e43
2013-04-24Extension of segmentation to 8 segments.Paul Wilkins
Also some further simplification following removal of top node code. There is an issue in regards to the shared file vp8cx.h in regard to the roi_map as this interface assumes that there are only 4 segments. I have left the value here as 4 for now meaning that the roi_map interface is broken for VP9. Note that this change would have been easier if I hadn't had to search for hard wire instances of the number 4 and <= 3. Change-Id: Ia8b6deea4be4dbd20deb1656e689dd43a5f190e8

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

2013-02-13Add support for tile rows.Ronald S. Bultje
These allow sending partial bitstream packets over the network before encoding a complete frame is completed, thus lowering end-to-end latency. The tile-rows are not independent. Change-Id: I99986595cbcbff9153e2a14f49b4aa7dee4768e2
2013-02-12Add tile column size limits (256 pixels min, 4096 pixels max).Ronald S. Bultje
This is after discussion with the hardware team. Update the unit test to take these sizes into account. Split out some duplicate code into a separate file so it can be shared. Change-Id: I8311d11b0191d8bb37e8eb4ac962beb217e1bff5
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
