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).

2011-04-12Change rc undershoot/overshoot semanticsJohn Koleszar
This patch changes the rc_undershoot_pct and rc_overshoot_pct controls to set the "aggressiveness" of rate adaptation, by limiting the amount of difference between the target buffer level and the actual buffer level which is applied to the target frame rate for this frame. This patch was initially provided by arosenberg at logitech.com as an attachment to issue #270. It was modified to separate these controls from the other unrelated modifications in that patch, as well as to use the pre-existing variables rather than introducing new ones.

2011-01-19Merge "Implement error tracking in the decoder"John Koleszar
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

2011-01-07CQ ModePaul Wilkins
The merge includes hooks to for CQ mode and other code changes merged from the test branch. CQ mode attempts to maintain a more stable quantizer within a clip whilst also trying to adhere to a guidline maximum bitrate. The existing target data rate parameter is used to specify the guideline maximum bitrate. A new parameter allows the user to specify a target CQ level. For normal (non kf/gf/arf) frames, the quantizer will not drop BELOW the user specified value (0-63). However, in some cases the encoder may choose to impose a target CQ that is above that specified by the user, if it estimates that consistent use of the target value is not compatible with guideline maximum bitrate.

2010-12-17Add psnr/ssim tuning optionJohn Koleszar
Add a new encoder control, VP8E_SET_TUNING, to allow the application to inform the encoder that the material will benefit from certain tuning. Expose this control as the --tune option to vpxenc. The args helper is expanded to support enumerated arguments by name or value. Two tunings are provided by this patch, PSNR (default) and SSIM. Activity masking is made dependent on setting --tune=ssim, as the current implementation hurts speed (10%) and PSNR (2.7% avg, 10% peak) too much for it to be a default yet.

2010-12-17Inform caller of decoder about updated referencesHenrik Lundin
Inform the caller of the decoder if a decoded frame updated last, golden, or altref frames, required for realtime communication proposed in document VP8 RTP payload format. Added a new vpx_codec_control called VP8D_GET_LAST_REF_UPDATES, to be called after vpx_codec_decode. The control will indicate which of the reference frames that were updated by setting the 3 LSBs in the input int (pointer). Change-Id: Iac9db60dac414356c7ffa0b0fede88cb91e11bd7

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.

2010-09-23Add getter functions for the interface data symbolsJohn Koleszar
Having these symbols be available as functions rather than data is occasionally more convenient. Implemented this way rather than a get-codec-by-id style to avoid creating a link-time dependency between the encoder and the decoder.

2010-06-05shared library support (.so)John Koleszar
This patch adds support for building shared libraries when configured with the --enable-shared switch. Building DLLs would require more invasive changes to the sample utilities than I want to make in this patch, since on Windows you can't use the address of an imported symbol in a static initializer. The best way to work around this is proably to build the codec interface mapping table with an init() function, but dll support is of questionable value anyway, since most windows users will probably use a media framework lib like webmdshow, which links this library in staticly.

2010-06-01setup experimental infrastructureJohn Koleszar
This patch creates some basic infrastructure for doing bitstream- incompatible changes to the VP8 encoder. The key parts are: - --enable-experimental configure switch, to enable support for this incompatible bitstream. This switch is required to be set to enable any "experiments" - A list for "experiments" which translate into --enable-<experiment> options and CONFIG_<experiment> macros. - The high bit of the "Version" field is used to indicate that the bitstream was produced by an experimental encoder. The decoder will fail to decode an experimental bitstream without --enable-experimental. - A new "vp8x" encoder interface is created to set the experimental bit. - The vp8x encoder interface is made the default for ivfenc in experimental mode.
