* 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
|
* mpeg12dec: Extract CC user data into frame side dataJohn Stebbins2013-11-26
| | | | Signed-off-by: Anton Khirnov <anton@khirnov.net>
* 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| | | | | | | XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it.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>
* lavu: Add interleaved 4:2:2 8/10-bit formatsKieran Kunhya2013-09-21
| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mem: Introduce av_reallocpLuca Barbato2013-09-16

* vdpau: deprecate old codec-specific pixel formatsRémi Denis-Courmont2013-08-05
| | | | Signed-off-by: Anton Khirnov <anton@khirnov.net>
* mem: Add av_realloc_array and av_reallocp_arrayMartin Storsjö2013-06-04
| | | | | | These help avoiding overflows and simplify error handling. Signed-off-by: Martin Storsjö <martin@martin.st>
* Move get_logical_cpus() from lavc/pthread to lavu/cpu.Anton Khirnov2013-05-24
| | | | | It will be useful in lavfi, and could conceivably be useful to the user applications as well.
* pixdesc: rename PIX_FMT_* flags to AV_PIX_FMT_FLAG_*Anton Khirnov2013-05-15
|
* pixdesc: add function to return pixel format with swapped endiannesJanne Grunau2013-05-06
|
* pixdesc/pixfmt: Add XYZ colorspace for XYZ 12-bit valuesNicolas Bertrand2013-04-04
| | | | Signed-off-by: Diego Biurrun <diego@biurrun.de>
* pixdesc: add a function for counting planes in a pixel format.Anton Khirnov2013-03-19
|
* lavc: move AVFrame.hwaccel_picture_private to Picture.Anton Khirnov2013-03-08
| | | | | This field is private and should not be present in a public struct. It is only used in DXVA with mpegvideo-based decoders currently.
* avstring: Add locale independent versions of some ctype.h functionsReimar Döffinger2013-03-07
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* lls: move to the private namespaceLuca Barbato2013-02-28
| | | | The functions are private.
* dict: add av_dict_parse_string()Justin Ruggles2013-01-25
| | | | | | Can be used to set multiple key/value pairs from a string. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lavu: Add av_strnstr()Vladimir Pantelic2013-01-25
| | | | | | | This is a length limited version of strstr() Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lavu: Add an API for calculating HMAC (RFC 2104)Martin Storsjö2013-01-15
| | | | | | | This supports HMAC-MD5 and HMAC-SHA1 for now, other hashes are simple to add. Signed-off-by: Martin Storsjö <martin@martin.st>
* Add version bump and APIchanges entry for Add AV_PIX_FMT_VDPAU.Diego Biurrun2013-01-12
| | | | Also fix a lavu version typo in APIchanges.
* avstring: add av_basename and av_dirnameLuca Barbato2012-12-29
| | | | Thread safe version of the common basename and dirname.
* cpu.h: define AV_CPU_FLAG_MMX2 for libavutil major 52Janne Grunau2012-11-16
|
* lavu: rename audioconvert.* to channel_layout.* and deprecate audioconvert.hJustin Ruggles2012-11-11
|
* lavu: add av_ctz() for trailing zero bit countJustin Ruggles2012-11-05
|
* lavu: remove disabled FF_API_AV_FIFO_PEEK cruftAnton Khirnov2012-10-23
|
* lavu: remove disabled avoptions cruftAnton Khirnov2012-10-23
|
* lavu: remove disabled FF_API_GET_BITS_PER_SAMPLE_FMT cruftAnton Khirnov2012-10-23
|
* lavu: bump major to 52Anton Khirnov2012-10-23
| | | | | | In addition to the recent tables mess, the AVOption defaults behavior changed, so an old lavc used with a new lavu will get completely messed up defaults.
* lavu: postpone recent deprecations until the next major bumpAnton Khirnov2012-10-23
|
* avutil: Add AVERROR_EXPERIMENTALNathan Caldwell2012-10-21
| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* Move av_reverse table to libavcodecDiego Biurrun2012-10-12
| | | | It is only used in that library.
* pixdesc: add functions for accessing pixel format descriptors.Anton Khirnov2012-10-12
| | | | | | | | Make av_pix_fmt_descriptors table static on next major bump. Making the table public is dangerous, since the caller has no way to know how large it actually is. It also prevents adding new fields to AVPixFmtDescriptor without a major bump.
* avutil: Add functions for allocating opaque contexts for algorithmsMartin Storsjö2012-10-11
| | | | | | | | | | | | The current API where the plain size is exposed is not of much use - in most cases it is allocated dynamically anyway. If allocated e.g. on the stack via an uint8_t array, there's no guarantee that the struct's members are aligned properly (unless the array is overallocated and the opaque pointer within it manually aligned to some unspecified alignment).

* pixfmt: add AV_ prefixes to PIX_FMT_*Anton Khirnov2012-10-08
|
* samplefmt: make av_samples_alloc() initialize the data to silence.Anton Khirnov2012-10-04
| | | | Right now the buffer is zeroed, which does not represent silence for U8(P).
* lavu/audioconvert: add a second low frequency channel.Tim Walker2012-09-12
| | | | | | Can be used by DTS-HD, TrueHD and E-AC-3, among others. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
* avopt: Reorder the default_val struct, making i64 the first fieldMartin Storsjö2012-09-04
| | | | | | Also mention this change in APIchanges. Signed-off-by: Martin Storsjö <martin@martin.st>
* Don't include common.h from avutil.hMartin Storsjö2012-08-15
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* dict: add av_dict_count()Mans Rullgard2012-08-10
| | | | | | | | This adds a function to retrieve the number of entries in a dictionary and updates the places directly accessing what should be an opaque struct to use this new function instead. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: build: replace mmx2 by mmxextDiego Biurrun2012-08-03
| | | | | | | Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.
* mem: introduce av_malloc_array and av_mallocz_arrayLuca Barbato2012-07-14
| | | | | Both function ease allocating large arrays implementing the overflow check inside it.
* Clarify Doxygen comment for FF_API_* #defines.Diego Biurrun2012-07-04
