* cosmetics: Fix spelling mistakesVittorio Giovara2016-05-04
| | | | Signed-off-by: Diego Biurrun <diego@biurrun.de>
* lavu: add an API function to return the Libav version stringwm42015-07-02
| | | | | | | | This returns something like "v12_dev0-1332-g333a27c". This is much more useful than the individual library versions, of which there are too many, and which are very hard to map back to releases or git commits. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* avutil: move av_get_time_base_q() after include rational.hMichael Niedermayer2014-04-22
| | | | | | | Fix compilation Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* 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>
* 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.
* doxy: Define a group for libswscale documentationLuca Barbato2013-12-13
| | | | Uniform the style and eliminate a warning on newer doxygen version..
* doxy: Document avlogLuca Barbato2013-10-05
| | | | Provide some information for every function and add a group.

* lavu: add av_usleep() functionMans Rullgard2012-06-22
| | | | | | | | | | | | | | | This function implements a delay using the first available of the following functions: - nanosleep() - usleep() - Sleep() (Windows) The conditional #includes in time.c are simplified by including unistd.h and windows.h whenever they are available rather than having these lines triggered by specific functions.

* Bump lavu minor and add an APIChanges entry for audioconvert functions.Anton Khirnov2012-06-10
|
* opt: Add av_opt_set_bin()Samuel Pitoiset2012-05-26
| | | | | | | Introduce a new function to set binary data through AVOption, avoiding having to convert the binary data to a string inbetween. Signed-off-by: Martin Storsjö <martin@martin.st>
* Add missing version bumps and APIchanges/Changelog entries.Anton Khirnov2012-05-15
|
* avutil: add av_parse_cpu_flags() functionMans Rullgard2012-04-25
| | | | | | | This moves the cpu flag parsing code from avconv to avutil so it can be accessed elsewhere. Signed-off-by: Mans Rullgard <mans@mansr.com>
* avutil: add audio fifo bufferJustin Ruggles2012-04-20
| | | | | The functions operate on the sample level rather than the byte level and work with all audio sample formats.
* avutil: use align == 0 for default alignment in audio sample buffer functionsJustin Ruggles2012-04-09

* audioconvert: make av_get_channel_layout accept composite names.Nicolas George2012-04-08

* avutil: add av_get_packed_sample_fmt() and av_get_planar_sample_fmt()Justin Ruggles2012-04-08
| | | | Based on a patch by Clément Bœsch <ubitux@gmail.com>
* avutil: Add av_get_default_channel_layout()Justin Ruggles2012-04-05
| | | | Also, use the new function in the AC-3 encoder.
* cpu: add av_set_cpu_flags_mask().Anton Khirnov2012-03-06
|
* doxygen: Remove documentation for non-existing parameters; misc small fixes.Diego Biurrun2012-02-28
|
* avutil: add AVERROR_UNKNOWNJustin Ruggles2012-02-25
| | | | | Useful to return instead of -1 when the cause of the error is unknown, typically from an external library.
* Remove libpostproc.Diego Biurrun2012-02-23
| | | | | | | | This library does not fit into Libav as a whole and its code is just a maintenance burden. Furthermore it is now available as an external project, which completely obviates any reason to keep it around. URL: http://git.videolan.org/?p=libpostproc.git
* avutil: add av_rescale_q_rnd() to allow different roundingJustin Ruggles2012-02-20
|
* pixdesc: mark pseudopaletted formats with a special flag.Anton Khirnov2012-02-08
| | | | | | This makes it possible to dintinguish them from PAL8. Fixes an invalid write in avpicture_layout().
* avutil: make intfloat api publicPaul B Mahol2012-01-30
| | | | | | | | The functions are already av_ prefixed and intfloat header is already provided. Install libavutil/intfloat.h Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* Add basic libavdevice documentation.Anton Khirnov2011-12-12

* audioconvert: add some additional channel and channel layout macrosJustin Ruggles2011-12-09
|
* audioconvert: change 7.1 "wide" layout to use side surround channelsJustin Ruggles2011-12-09
|
* Make channel layout masks unsignedMans Rullgard2011-11-25
| | | | | | | | | | It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>

* libavutil: add utility functions to simplify allocation of audio buffers.Justin Ruggles2011-11-23

* doxy: structure libavformat groupsLuca Barbato2011-11-22

* doxy: introduce an empty structure in libavcodecLuca Barbato2011-11-22
|
* doxy: provide a start page and document libavutilLuca Barbato2011-11-22
| | | | | | Introduce a basic layout, the subpages are currently left empty. Split libavutil in multiple groups as example of the structure
* avutil: Add av_timegm as a public functionMartin Storsjö2011-11-16
| | | | | | | | | | This is useful, since the normal timegm function isn't a standard function (requiring _BSD_SOURCE or _SVID_SOURCE on glibc to be visible, and not available on e.g. windows). The widely available function mktime uses the local time zone, which requires ugly workarounds to handle UTC time. Signed-off-by: Martin Storsjö <martin@martin.st>
