* Add transformation matrix API.Vittorio Giovara2014-05-19
| | | | | | | | | | | Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and frame side data (respectively) to describe a display transformation matrix for linear transformation operations on the decoded video. Add functions to easily extract a rotation angle from a matrix and conversely to setup a matrix for a given rotation angle. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavu: Add a pixel format for new VDA hwaccelAnton Khirnov2014-05-11
| | | | | The current hwaccel is broken and cannot be fixed in a compatible way. It will be deprecated and replaced with a new one.
* avutil: Add av_get_time_base_q()Derek Buitenhuis2014-04-22
| | | | | | | | This fixes usage of AV_TIME_BASE_Q in C++ applications, which cannot use compound literals directly in their code. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* crc: add ANSI CRC16 LEAlessandro Ghedini2014-04-17
| | | | | | This adds the reversed byte-order version of the ANSI CRC16. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavu: Add packed YVYU422 pixel formatVittorio Giovara2014-04-07

* replaygain: correctly parse peak valuesAlessandro Ghedini2014-04-04
| | | | | | | | | | | | | | | According to the ReplayGain spec, the peak amplitude may overflow and may result in peak amplitude values greater than 1.0 with psychoacoustically coded audio, such as MP3. Fully compliant decoders must allow peak overflows. Additionally, having peak values in the 0<->UINT32_MAX scale makes it more difficult for applications to actually use the peak values (e.g. when implementing clipping prevention) since values have to be rescaled down. This patch corrects the peak parsing by removing the rescaling of the decoded values between 0 and UINT32_MAX and the 1.0 upper limit. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* log: Support for 256color terminalsLuca Barbato2014-04-03
| | | | | | | | | And provide extended coloring capabilities for debugging. The default colors do not change in 256 more to keep supporting people using Black on White, White on Black and Solarized terminals. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* frame: add a function for removing side data from a frameAnton Khirnov2014-03-24

* frame: add a convenience function for copying AVFrame dataAnton Khirnov2014-02-24
|
* AVOptions: add flags for read/read-only optionsAnton Khirnov2014-02-19
|
* AVOptions: deprecate unused AV_OPT_FLAG_METADATAAnton Khirnov2014-02-19
| | | | | It was never used since it was added and the things it was intended for are now exported differently.
* lavu: add AV_FRAME_DATA_DOWNMIX_INFO side data type.Tim Walker2014-02-15
|
* avframe: add AV_FRAME_DATA_MATRIXENCODING side data type.Tim Walker2014-01-05
| | | | Includes a libavcodec utility function to update a frame's side data.
* lavu: Add values for various Dolby flags to the AVMatrixEncoding enum.Tim Walker2014-01-05
|
* lavu: Move preprocessor macros in a separate fileLuca Barbato2013-12-29
| | | | And remove all the circular inclusions of avutil.h while at it.
* avutil: Move library version related macros to version.hDiego Biurrun2013-12-26
| | | | This is a more sensible place for these macros.
* avutil: Remove deprecated intfloat_readwrite codeDiego Biurrun2013-12-16
| | | | It was deprecated over two years ago.
* Bump libavutil major version to account for the LLS API/ABI changes.Reinhard Tartler2013-12-14
| | | | | | | | Commit 41578f70cf8aec8e7565fba1ca7e07f3dc46c3d2 changed the LLS API, which was called from libavcodec. Thus using an old libavcodec with a new libavutil will break. All scheduled API changes are deferred to the next bump.
* avutil: Add deprecation ifdefs around obsolete intfloat codeDiego Biurrun2013-12-13
| | | | This long-deprecated code should disappear at the next version bump.
* avframe: add codec-independent stereoscopic metadataVittorio Giovara2013-12-09

* Move av_fast_{m,re}alloc from lavc to lavu.Anton Khirnov2013-11-14
|
* Deprecate obsolete XvMC hardware decoding supportDiego Biurrun2013-11-13
| | | | | | | XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it. Furthermore XvMC is not implemented within the hwaccel framework, but requires its own specific code in the MPEG-1/2 decoder, which is a maintenance burden.
* h264: wait for initial complete frame before outputing framesJohn Stebbins2013-10-31
| | | | | | | | This can be optionally disabled whith the "output_corrupt" flags option. When in "output_corrupt" mode, incomplete frames are signalled through AVFrame.flags FRAME_FLAG_INCOMPLETE_FRAME. Signed-off-by: Anton Khirnov <anton@khirnov.net>
