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

2014-02-06Layer based rate control for CBR mode.Marco Paniconi
This patch adds a buffer-based rate control for temporal layers, under CBR mode.

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

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.

frames" into experimental
2012-11-09Packing Altref along with succeeding frame and length encoding framesVignesh Venkatasubramanian
The altref frame is packed along with the next P frame. So that outside of the codec there are now only two types of frames P and I. Also, now it is one frame in and one frame out with respect to the codec. Apart from that, all the frames are length encoded with the length of each frame appended to the frame itself. There are two categories of frames and each of them will look as follows: - Packed frames (an altref along with the succeeding p frame) - altref_frame_data | altref_lenngth | frame_data | length - Unpacked frames (all frames other than the above) - frame_data | length Change-Id: If1eabf5c473f7d46b3f2d026bd30c803588c5330

2012-03-15WebM Experimental Codec Branch SnapshotYaowu Xu
This is a code snapshot of experimental work currently ongoing for a next-generation codec. The codebase has been cut down considerably from the libvpx baseline. For example, we are currently only supporting VBR 2-pass rate control and have removed most of the code relating to coding speed, threading, error resilience, partitions and various other features. This is in part to make the codebase easier to work on and experiment with, but also because we want to have an open discussion about how the bitstream will be structured and partitioned and not have that conversation constrained by past work. Our basic working pattern has been to initially encapsulate experiments using configure options linked to #IF CONFIG_XXX statements in the code. Once experiments have matured and we are reasonably happy that they give benefit and can be merged without breaking other experiments, we remove the conditional compile statements and merge them in. Current changes include: * Temporal coding experiment for segments (though still only 4 max, it will likely be increased). * Segment feature experiment - to allow various bits of information to be coded at the segment level. Features tested so far include mode and reference frame information, limiting end of block offset and transform size, alongside Q and loop filter parameters, but this set is very fluid. * Support for 8x8 transform - 8x8 dct with 2nd order 2x2 haar is used in MBs using 16x16 prediction modes within inter frames. * Compound prediction (combination of signals from existing predictors to create a new predictor). * 8 tap interpolation filters and 1/8th pel motion vectors. * Loop filter modifications. * Various entropy modifications and changes to how entropy contexts and updates are handled. * Extended quantizer range matched to transform precision improvements. There are also ongoing further experiments that we hope to merge in the near future: For example, coding of motion and other aspects of the prediction signal to better support larger image formats, use of larger block sizes (e.g. 32x32 and up) and lossless non-transform based coding options (especially for key frames). It is our hope that we will be able to make regular updates and we will warmly welcome community contributions. Please be warned that, at this stage, the codebase is currently slower than VP8 stable branch as most new code has not been optimized, and even the 'C' has been deliberately written to be simple and obvious, not fast. The following graphs have the initial test results, numbers in the tables measure the compression improvement in terms of percentage.

2011-06-28Proposing an extension to the encoder and decoder interfaces.Stefan Holmer

2011-05-19Adding error-concealment to the decoder.Stefan Holmer
The error-concealer is plugged in after any motion vectors have been decoded. It tries to estimate any missing motion vectors from the motion vectors of the previous frame. Intra blocks with missing residual are replaced with inter blocks with estimated motion vectors. This feature was developed in a separate sandbox (sandbox/holmer/error-concealment).

2011-01-19Implement error tracking in the decoderHenrik Lundin
A new vpx_codec_control called VP8D_GET_FRAME_CORRUPTED. The output from the function is non-zero if the last decoded frame contains corruption due to packet losses. The decoder is also modified to accept encoded frames of zero length. A zero length frame indicates to the decoder that one or more frames have been completely lost. This will mark the last decoded reference buffer as corrupted. The data pointer can be NULL if the length is zero. Change-Id: Ic5902c785a281c6e05329deea958554b7a6c75ce
2010-10-27Eliminate more warnings.Timothy B. Terriberry
This eliminates a large set of warnings exposed by the Mozilla build system (Use of C++ comments in ISO C90 source, commas at the end of enum lists, a couple incomplete initializers, and signed/unsigned comparisons). It also eliminates many (but not all) of the warnings expose by newer GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite without checking the return values). There are a few spurious warnings left on my system: ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used uninitialized in this function gcc seems to be unable to figure out that the value shortcut doesn't change between the two if blocks that test it here. ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned expression >= 0 is always true ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned expression >= 0 is always true This is true, so far as it goes, but it's comparing against an enum, and the C standard does not mandate that enums be unsigned, so the checks can't be removed.
