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

2013-09-17Modified resize unit test to output test vectorAdrian Grange
Modified the resize unit test so that it optionally writes the encoded bitstream to file. The macro WRITE_COMPRESSED_STREAM should be set to 1 to enable output of the test bitstream; it is set to 0 by default. Change-Id: I7d436b1942f935da97db6d84574a98d379f57fb1

Added the resize_test unit test to the VP9 set. Set g_in_frames = 0 to avoid a problem when the total number of frames being encoded is smaller than g_in_frames. In this case the test will not have access to the encoded frames and will not be able to compare them for testing for encoder/decoder mismatch. Change-Id: I0d2ff8ef058de7002c5faa894ed6ea794d5f900b

2013-06-24Fix loopfilter of leftmost 4x4 edges in SBJohn Koleszar
For cases where there's no transform set in bit 0 (the left edge of the SB) but bit 0 of mask_4x4_int is set (the edge 4 pixels from the left edge needs filtering), it was incorrectly being skipped before. This situation only happens on the leftmost edge of the image, as the edge at column 0 is intentionally skipped since there aren't pixels to the left to read.

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

* changes: Restore SSSE3 subpixel filters in new convolve framework Convert subpixel filters to use convolve framework Add 8-tap generic convolver
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
2013-02-05Add 8-tap generic convolverJohn Koleszar
This commit introduces a new convolution function which will be used to replace the existing subpixel interpolation functions. It is much the same as the existing functions, but allows for changing the filter kernel on a per-pixel basis, and doesn't bake in knowledge of the filter to be applied or the size of the resulting block into the function name. Replacing the existing subpel filters will come in a later commit. Change-Id: Ic9a5615f2f456cb77f96741856fc650d6d78bb91

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.

2012-12-0732x32 transform for superblocks.Ronald S. Bultje
This adds Debargha's DCT/DWT hybrid and a regular 32x32 DCT, and adds code all over the place to wrap that in the bitstream/encoder/decoder/RD. Some implementation notes (these probably need careful review): - token range is extended by 1 bit, since the value range out of this transform is [-16384,16383]. - the coefficients coming out of the FDCT are manually scaled back by 1 bit, or else they won't fit in int16_t (they are 17 bits). Because of this, the RD error scoring does not right-shift the MSE score by two (unlike for 4x4/8x8/16x16). - to compensate for this loss in precision, the quantizer is halved also. This is currently a little hacky. - FDCT and IDCT is double-only right now. Needs a fixed-point impl. - There are no default probabilities for the 32x32 transform yet; I'm simply using the 16x16 luma ones. A future commit will add newly generated probabilities for all transforms. - No ADST version. I don't think we'll add one for this level; if an ADST is desired, transform-size selection can scale back to 16x16 or lower, and use an ADST at that level. Additional notes specific to Debargha's DWT/DCT hybrid: - coefficient scale is different for the top/left 16x16 (DCT-over-DWT) block than for the rest (DWT pixel differences) of the block. Therefore, RD error scoring isn't easily scalable between coefficient and pixel domain. Thus, unfortunately, we need to compute the RD distortion in the pixel domain until we figure out how to scale these appropriately. Change-Id: I00386f20f35d7fabb19aba94c8162f8aee64ef2b
