* lavfi: make formats API private on next bump.Anton Khirnov2012-06-05
| | | | | It is only useful inside filters and we don't allow user filters for now.
* lavfi: deprecate default config_props() callback and refactor ↵Mina Nagy Zaki2012-05-22
| | | | | | | | | | | | avfilter_config_links() Link properties have to be checked after config_props() is called to make sure everything is sane, so the default config_props() for output links was redundant. Remove now empty defaults.c Signed-off-by: Anton Khirnov <anton@khirnov.net>
* avfilter: Move ff_get_ref_perms_string() to where it is used.Diego Biurrun2012-05-15
| | | | This fixes a compilation failure with -DDEBUG.
* lavfi: move buffer management function to a separate file.Anton Khirnov2012-05-15
|
* lavfi: move video-related functions to a separate file.Anton Khirnov2012-05-15
| | | | | This is easier to follow than having them randomly scattered in avfilter.c and defaults.c.
* lavfi: add channel layout/sample rate negotiation.Anton Khirnov2012-05-14

* lavfi: move audio-related functions to a separate file.Anton Khirnov2012-05-09
| | | | | This is easier to follow than having them randomly scattered in avfilter.c and defaults.c.
* lavfi: remove some audio-related function from public API.Anton Khirnov2012-05-09
| | | | | | | | Those functions are only useful inside filters. It is better to not support user filters until the API is more stable. This breaks audio filtering API and ABI in theory, but since it's unusable right now this shouldn't be a problem.
* lavfi: simplify signature for avfilter_get_audio_buffer() and friendsStefano Sabatini2012-05-09
| | | | | | | | | | | | The additional parameters are just complicating the function interface. Assume that a requested samples buffer will *always* have the format specified in the requested link. This breaks audio filtering API and ABI in theory, but since it's unusable right now this shouldn't be a problem. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavfi: cleanup avfilter_get_audio_buffer() and pals.Stefano Sabatini2012-05-09
| | | | | | | | | | | | | | | Remove AVFilterBufferRefAudioProps.size, and use nb_samples in its place everywhere. This is required as the size in the audio buffer may be aligned, so it may not contain a well defined number of samples. Also remove the useless planar parameter, which can be deduced from the sample format. This is technically an API and ABI break, but since the audio part of lavfi is not usable now, this should not be a problem in practice. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavfi: add avfilter_get_audio_buffer_ref_from_arrays().Stefano Sabatini2012-05-09
| | | | Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavfi: add extended_data to AVFilterBuffer.Anton Khirnov2012-05-09
| | | | | This is similar to what has previously been done in AVFrame to allow dealing with more than 8 channels.
* lavfi: add a function for copying properties from AVFilterBufferRef->AVFrameAnton Khirnov2012-05-09
| | | | Based on a commit by Stefano Sabatini <stefano.sabatini-lala@poste.it>
* lavfi: uninline avfilter_copy_buffer_ref_props().Anton Khirnov2012-05-07
| | | | | A nontrivial public function such as this should most certainly NOT be inline.
* lavfi: support audio in avfilter_copy_frame_props().Anton Khirnov2012-05-07
|
* lavfi: add avfilter_copy_frame_props()Stefano Sabatini2011-12-25
| | | | | avfilter_copy_frame_props() avoids code duplication and increases robustness.
* 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>
* avfilter: Don't copy garbage from the stack when setting up video pictures.Alex Converse2011-11-03

* avfilter: Surround function only used in debug mode by appropriate #ifdef.Diego Biurrun2011-05-29
| | | | | This fixes the warning: libavfilter/avfilter.c:219: warning: ‘ff_get_ref_perms_string’ defined but not used
* lavfi: print key-frame and picture type information in ff_dlog_ref()Stefano Sabatini2011-05-16

* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

* Make avfilter_config_links() use the timebase of the first input linkStefano Sabatini2010-10-12
| | | | | | | | | | | of a filter for setting the output timebase, if there is such a link, rather than always use AV_TIME_BASE_Q.
