Vittorio Giovara	5655732c77	avfilter: add needs_writable field to the internal AVFilterPad structure	11 years ago
Nicolas George	6e2473edfd	lavfi: parsing helper for unknown channel layouts. Make ff_parse_channel_layout() accept unknown layouts too.	11 years ago
Michael Niedermayer	d5ec8ba7f2	Do not leave positive values undefined when negative are defined as error Define positive return values as non errors and leave further meaning undefined This allows future extensions to use these values Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	0767bfd199	lavfi: allow user-provided execute() callbacks	11 years ago
Paul B Mahol	211a185cba	avfilter/avfilter: check allocation failure in ff_insert_pad() Signed-off-by: Paul B Mahol <onemda@gmail.com>	11 years ago
Michael Niedermayer	247fa6c27c	avfilter: remove ff_copy_int*_list The functions are unused Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Diego Biurrun	7950e519bb	Disable deprecation warnings for cases where a replacement is available	11 years ago
Diego Biurrun	45dd1ae1b3	avfilter: Add some missing FF_API_AVFILTERBUFFER ifdefs	11 years ago
Anton Khirnov	129bb23843	lavfi: add a slice threading infrastructure Mostly based on libavcodec's	12 years ago
Anton Khirnov	1565cbc65c	lavfi: make avfilter_free() remove the filter from its graph.	12 years ago
Anton Khirnov	bc1a985ba0	lavfi: replace avfilter_open() with avfilter_graph_alloc_filter(). Since we do not support "standalone" filters not attached to an AVFilterGraph, we should not have a public function to create such filters. In addition that function is horribly named, the action it does cannot be possibly described as "opening" a filter.	12 years ago
Nicolas George	79d8cfacf0	lavfi: loop on request_frame if necessary. Some filters need several input frames before producing output. For these filter, it becomes simpler to return 0 in request_frame() and let the framework call it again until output has been produced.	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
Michael Niedermayer	2468827c06	internal.h: remove start/end_frame from AVFilterPad Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	c0c0b19644	lavfi: remove some draw_slice related code that has become unneeded Reviewed-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	8227a0b7df	libavfilter: update doxy for filter_frame Based on patch by Anton Khirnov Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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	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
Clément Bœsch	54a48d2f04	lavfi: fix references to avfilter_* functions that don't exist anymore.	12 years ago
Nicolas George	9de731e9d0	lavfi/sink_buffer: implement libav compatibility API. Implement av_buffersink_read() and av_buffersink_read_samples() for ffmpeg's version of buffersink. With this change, avconv linked against ffmpeg's libraries passes the same number of tests whether it uses ffbuffersink or buffersink_old.	12 years ago
Anton Khirnov	d4f89906e3	lavfi: add error handling to end_frame().	12 years ago
Anton Khirnov	e9b992d035	lavfi: add error handling to draw_slice().	12 years ago
Anton Khirnov	ebc8d97481	lavfi: add error handling to start_frame().	12 years ago
Nicolas George	cb6a20fa56	lavfi: add FF_*LINK_IDX convenience macros.	13 years ago
Nicolas George	97f86680eb	lavfi: make copy_buffer_ref common.	13 years ago
Anton Khirnov	cd99146253	lavfi: add error handling to filter_samples().	13 years ago
Stefano Sabatini	c17808cebd	lavfi: define macro AVFILTER_DEFINE_CLASS The macro can be used to define consistently the internal class of a filter, save some typing and factorize.	13 years ago
Anton Khirnov	58b049f2fa	lavfi: support automatically inserting the fifo filter when needed. This breaks libavfilter ABI.	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
Anton Khirnov	9d0bfc5052	lavfi: make AVFilterPad opaque after two major bumps. It will allow adding new fields to it without ABI breaks.	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
Michael Niedermayer	7b0d362567	libavfilter: make ff_null_start_frame_keep_ref() a non static inline function. Its only used through the start_frame pointer and thus cannot be inlined easily. It also appears to break compilation with some unidentified compiler on darwin. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	1488c4dc0b	lavfi: move tracing utilities definition from video.c to avfilter.c These utilities are meant to be defined in avfilter.c, since they are generic and thus contain both audio and video code.	13 years ago
Anton Khirnov	803391f719	lavfi: remove request/poll and drawing functions from public API on next bump They are only useful inside filters and we don't allow user filters for now.	13 years ago
Anton Khirnov	fa417fcd27	lavfi: make avfilter_insert_pad and pals private on next bump. They are only useful inside filters and we don't allow user filters for now.	13 years ago
Anton Khirnov	8eb9bf0933	avfiltergraph: make some functions static. They are not used outside of avfiltergraph.c	13 years ago
Michael Niedermayer	3448404a70	libavfilter: add ff_parse_time_base() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
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
Stefano Sabatini	6b55aab01a	lavfi: create buffer reference in filters which need to access the ref later Also add internal function ff_null_start_frame_keep_ref(). Fix crash when a following filter (e.g. settb) will unref the reference passed by start_frame(), and then the reference is accessed in end_frame() through inlink->cur_buf.	13 years ago
Nicolas George	2ce7972779	avfiltergraph: add avfilter_graph_request_oldest(). Keep a heap of all sink links ordered by timestamps.	13 years ago
Michael Niedermayer	f068ce570f	avfilter: pool draining and self destruction support. This should fix a memleak. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	386aee6864	sink_buffer: copy list of provided formats in the context A list of formats may have been dynamically created by the calling code, and thus should not be referenced by the sink buffer context. Avoid possible invalid data reference.	13 years ago
Stefano Sabatini	8fe0c527f3	lavfi: add LUT (LookUp Table) generic filters Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	e64de2ad1a	lavfi: document AVFilterCommand fields	13 years ago
Stefano Sabatini	4381bddc9f	lavfi: consistently use int for sample_rate in AVFilterLink and AVFilterBufferRefAudioProps Also consistent with AVCodecContext.sample_rate. Simplify/avoid pointless type checks and conversions. Breaks audio API/ABI.	13 years ago
Michael Niedermayer	3d8176d2f5	avfilter: Add avfilter_graph_que_command() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	e26782a9b4	lavfi: add ff_parse_pixel_format() internal function, and use it Reduce code duplication.	13 years ago
Mina Nagy Zaki	3f07d40ea2	lavfi: add internal functions for parsing format arguments Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it>	13 years ago
