Michael Niedermayer	00948ff876	avfilter/audio: use av_mallocz_array() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	c9c7bc4493	lavfi: switch ff_default_get_audio_buffer() to av_frame_get_buffer() This simplifies the code and avoids using libavcodec-specific avcodec_fill_audio_frame().	12 years ago
Michael Niedermayer	f963c77856	avfilter: avoid direct access to "frame"->channels This avoids ABI issues Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	7e350379f8	lavfi: switch to AVFrame. Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it and use AVFrame instead.	12 years ago
Nicolas George	b6afb2dde1	lavfi: support unknown channel layouts.	12 years ago
Nicolas George	82541d8330	lavfi: merge all filtering code into ff_filter_frame.	12 years ago
Nicolas George	2eb2e1798e	lavfi: add avfilter_get_audio_buffer_ref_from_arrays_channels. It is the same as avfilter_get_audio_buffer_ref_from_arrays except it has a "channels" and the channel layout can be 0.	12 years ago
Nicolas George	34de47aa35	lavfi: add an accessor for ref->audio->channels.	12 years ago
Nicolas George	238edd2fe3	lavfi: add a channels field to AVFilterLink. Also: fix af_pan and af_aresample, that forgot to update audio->channels.	12 years ago
Michael Niedermayer	3ed483cdfa	libavfilter: Support using filter_frame for video With this we can mix filters using filter_frame OR start/draw_slice/end Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	a0b8eec719	default_filter_frame: fix argument name Based on code by Anton Khirnov Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	cd7febd33f	lavfi: replace filter_samples by filter_frame Based on patch by Anton Khirnov Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	565e4993c6	lavfi: merge start_frame/draw_slice/end_frame Any alleged performance benefits gained from the split are purely mythological and do not justify added code complexity.	12 years ago
Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago
Nicolas George	8ad54a44eb	lavfi: check that buffer and link properties match.	12 years ago
Nicolas George	c262ddb8c5	lavfi: set sample_rate in the default allocator.	12 years ago
Nicolas George	beeba9161a	lavfi: add a closed field to AVFilerLink. It will help forward errors and maintain consistency.	13 years ago
Nicolas George	e54e30c889	lavfi: grant all permissions on mallocated audio buffers. The permissions not requested by the filter that created the buffer may be useful for a later filter and avoid a copy.	13 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Nicolas George	271ddb116c	lavfi: use min_perms and rej_perms for out pads. There are several reasons for doing that: 1. It documents the code for the reader and helps find inconsistencies and bugs. 2. For rej_perms, it guarantees the change will be done even if the output reference can be created by several code paths. 3. It can be used to predict cases where a copy will, or will not happen and optimize buffer allocation (for example not request a rare direct-rendering buffer from a device sink if it will be copied anyway). Note that a filter is still allowed to manage the permissions on its own without using these fields.	13 years ago
Reinhard Tartler	800750417f	lavfi: properly signal out-of-memory error in ff_filter_samples Found with a clang-scan report on http://fate.libav.org/csa/	13 years ago
Anton Khirnov	cd99146253	lavfi: add error handling to filter_samples().	13 years ago
Nicolas George	0689d5e17a	lavfi: implement samples framing on links. Links can be set up to group samples into buffers of specified minimum and maximum size.	13 years ago
Anton Khirnov	fa06623930	lavfi/audio: eliminate ff_default_filter_samples(). It currently does the following: 1) get a zeroed audio buffer 2) copy some properties (but not the data) of the input buffer to it 3) pass this buffer to the output filter This looks useless and is indeed not used by any filters, therefore delete it. Make ff_null_filter_samples() (just pass the buffer to the next filter) the new default.	13 years ago
Stefano Sabatini	c0b3c0ffb7	lavfi/audio: remove unused variable in ff_filter_samples() Fix warning: libavfilter/audio.c: In function ‘ff_filter_samples’: libavfilter/audio.c:193:13: warning: unused variable ‘size’ [-Wunused-variable]	13 years ago
Anton Khirnov	e026c9b390	lavfi/audio: don't set cur_buf in ff_filter_samples(). It's redundant, since the input buffer is passed as a parameter to the filter_samples() callback, and can lead to stale pointers remaining on the link.	13 years ago
Anton Khirnov	9cdf74f904	lavfi/audio: use av_samples_copy() instead of custom code. Fixes a possible invalid write, found by Nicolas George.	13 years ago
Anton Khirnov	9baeff9506	lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputs This is more consistent with naming in the rest of Libav.	13 years ago
Stefano Sabatini	134815a030	lavfi: change name of tracing functions and of the macro which enables them The enabling symbol is renamed FF_AVFILTER_TRACE. Avoid conflicts with the DEBUG macro, which may be defined for different purposes.	13 years ago
Nicolas George	9915a33fc2	lavfi/audio: fix size of copied samples. Fixes sporadic segfaults with some filters.	13 years ago
Anton Khirnov	7b3b24a8ee	lavfi: initialize pts to AV_NOPTS_VALUE when creating new buffer refs.	13 years ago
Stefano Sabatini	4d4098da00	lavfi: drop planar/packed negotiation support The planar/packed switch and the packing_formats list is no longer required, since the planar/packed information is now stored in the sample format enum. This is technically a major API break, possibly it should be not too painful as we marked the audio filtering API as unstable.	13 years ago
Michael Niedermayer	47aae2bc2e	lavfi: switch to _alt functions Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	0b45334a58	lavfi: move audio-related functions to a separate file. This is easier to follow than having them randomly scattered in avfilter.c and defaults.c.	13 years ago
