2014-02-13Add VP9 decoder support for external frame buffersFrank Galligan
Added support for external frame buffers to libvpx's VP9 decoder. If the external frame buffer functions are set then libvpx will call the get function whenever it needs a new frame buffer to decode a frame into. And it will call the release function whenever there are no more references to that buffer. Change-Id: Id2934d005f606af6e052fb6db0d5b7c02f567522

2014-02-11Merge "Add get release decoder frame buffer functions."Frank Galligan
2014-02-10Add get release decoder frame buffer functions.Frank Galligan
This CL changes libvpx to call a function when a frame buffer is needed for decode. Libvpx will call a release callback when no other frames reference the frame buffer. This CL adds a default implementation of the frame buffer callbacks. Currently only VP9 is supported. A future CL will add support for applications to supply their own frame buffer callbacks.

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

vpxdec stays in a loop when decoding vp9. This patch is a quick fix to stop the loop when all data has been decoded. Eventually we should move the vp9_get_raw_frame() call into vp8_get_frame(). Change-Id: I3f97b6b4e1fe9ba69f746a29fc54c3304956f661

Fix warning on windows: signed/unsigned mismatch on lines 415, 454 Comparison was between size_t data_sz >= int index_sz on 415 and unsigned int data_sz >= int index_sz on 454. Both might be changed to size_t but that would be tracing and replacing all comparisons is outside the scope of this change.

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 marker masksJohn Koleszar
The superframe index marker byte carries data in the lower 5 bits. Only the upper 3 should be used as part of the mask to detect it. By masking with 0xf0, the previous code was incorrect for frames over 65k bytes. Change-Id: I6248889f5af227457f359a56b2348ef6db87a3b4
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
2013-03-04Support 16K sequence codingJingning Han
Fixed a couple of variable/function definitions, as well as header handling to support 16K sequence coding at high bit-rates. The width and height are each specified by two bytes in the header. 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
2013-01-23Adds 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.

2013-01-16Start 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.

2012-11-15Pack invisible frames without lengthsJohn Koleszar
Modify the decoder to return the ending position of the bool decoder and use that as the starting position for the next frame. The constant-space algorithm for parsing the appended frame lengths is O(n^2), which is a potential DoS concern if n is unbounded. Revisit the appended lengths for use as partition lengths when multipartition support is added. In addition, this allows decoding of raw streams outside of a container without additional framing information, though it's insufficient to be able to remux said stream into a container.
