Yu Xiaolei	fbe9ae482d	avfilter: make avfilter_graph_get_filter use const string name Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Vittorio Giovara	d44bd7fb27	avfilter: add documentation for needs_writable	11 years ago
Vittorio Giovara	5c439b41d0	avfilter: have avfilter_get_by_name return const for next bump Signed-off-by: Anton Khirnov <anton@khirnov.net>	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
Anton Khirnov	77cc958f60	lavfi: add const to the AVFilter parameter of avfilter_graph_create_filter() This function should never modify the filter.	12 years ago
Diego Biurrun	bf4b0ed1d5	Add missing deprecation attributes	12 years ago
wm4	122536e01a	avfilter: fix preprocessor condition Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Stefano Sabatini	838bd73139	lavfi: create Libav-API compatibility layer for avfilter_graph_parse() at the next bump Add function avfilter_graph_parse_ptr() and favor it in place of avfilter_graph_parse(), which will be restored with the old/Libav signature at the next bump. If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the Libav-compatible signature for avfilter_graph_parse(). At the next major bump the current implementation of avfilter_graph_parse() should be dropped in favor of the Libav/old implementation. Should address trac ticket #2672.	12 years ago
Anton Khirnov	8b7dffc2d6	lavfi doxy: improve/extend AVFilter doxy.	12 years ago
Anton Khirnov	129bb23843	lavfi: add a slice threading infrastructure Mostly based on libavcodec's	12 years ago
Anton Khirnov	bc8c1cdc7b	lavfi doxy: add a page for lavfi.	12 years ago
Clément Bœsch	1776177b7f	lavfi: replace passthrough_filter_frame with a flag. With the introduction of AVFilterContext->is_disabled, we can simplify the custom passthrough mode in filters. This commit is technically a small compat break, but the timeline was introduced very recently. Doxy by Stefano Sabatini.	12 years ago
Stefano Sabatini	e1332ff324	lavfi/avfilter.h: fix typo	12 years ago
Michael Niedermayer	df9f9caba5	avfilter: Make enabled/disabled state available as a field of the AVFilterContext Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Clément Bœsch	fdd93eabfb	lavfi: add timeline support. Flag added in a few simple filters. A bunch of other filters can likely use the feature as well.	12 years ago
Clément Bœsch	b8a5c76131	lavfi: add frame counter into AVFilterLink and use it in filters.	12 years ago
Clément Bœsch	dcea58502c	lavfi: drop now unused shorthand field from AVFilter.	12 years ago
Michael Niedermayer	fd6228e657	lavfi: remove now unused args parameter from AVFilter.init and init_opaque This is mostly automated global search and replace The deprecated aconvert filter is disabled, if it still has users it should be updated Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	d69a4177b9	lavfi: remove now unused args parameter from AVFilter.init Conflicts: libavfilter/avfilter.c libavfilter/vf_drawtext.c libavfilter/vf_lut.c libavfilter/vf_select.c libavfilter/vf_setpts.c libavfilter/vsrc_color.c libavfilter/vsrc_movie.c Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	fa2a34cd40	lavfi: change the filter registering system to match the other libraries Removes an arbitrary hardcoded limit on the number of filters.	12 years ago
Anton Khirnov	7e8fe4be5f	lavfi: add a function for counting elements in AVFilterPad arrays. The caller needs to know what valid indices can be passed to avfilter_pad_get_name/type.	12 years ago
Anton Khirnov	7cdd737ba8	lavfi: mark filters with dynamic number of inputs or outputs with special flags This will be useful in avtools in the following commits. Any other caller might also want to know this information.	12 years ago
Anton Khirnov	1ba95a9cca	lavfi: add avfilter_init_dict() for initializing a filter with a dict.	12 years ago
Anton Khirnov	48a5adab62	lavfi: add avfilter_init_str() to replace avfilter_init_filter(). Drop the unused opaque parameter from its signature.	12 years ago
Anton Khirnov	1565cbc65c	lavfi: make avfilter_free() remove the filter from its graph.	12 years ago
Anton Khirnov	111367263a	lavfi: add AVFilterContext.graph. It will be useful in the following commits.	12 years ago
Anton Khirnov	c2c9801bc9	lavfi: deprecate avfilter_graph_add_filter(). Since this function adds a standalone filter to a filter graph and we do not support creating such filters, there is no reason for this function to exist.	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
Anton Khirnov	38f0c0781a	lavfi: merge avfiltergraph.h into avfilter.h We do not support using filters without AVFilterGraph in practice anyway, so there is no point in pretending we do.	12 years ago
Anton Khirnov	4a37d4b3f8	lavfi: add const to the pads parameter of avfilter_pad_get_name/type	12 years ago
Anton Khirnov	91d2efa7d6	lavfi: add const to AVFilterContext.filter. lavfi should never modify the filter through that pointer.	12 years ago
Anton Khirnov	8114c10160	lavfi: add avfilter_get_class(). Useful for examining options, the same as the corresponding functions for the other libs.	12 years ago
Anton Khirnov	c43a7ecad9	lavfi: remove now unused args parameter from AVFilter.init	12 years ago
Anton Khirnov	4fa1f52e33	af_resample: switch to an AVOptions-based system.	12 years ago
Anton Khirnov	b439c992c2	lavfi: switch to an AVOptions-based system.	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
Nicolas George	befbcc374d	lavfi: add common code to handle options parsing.	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
Clément Bœsch	aaf59766b9	lavfi/avfilter: remove now unused {src,cur,out}_buf. This was supposed to be removed in `565e4993`, but it was delayed due to the port of the remaining filters. These buffer ref pointers are not used anymore, thus dropped.	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
Stefano Sabatini	8f44170d30	lavfi/avfilter.h: clarify doxy for AVFilterLink.out_buf	12 years ago
Clément Bœsch	18d9398143	doxy: add ref for lavfi, lpp and lsws.	12 years ago
Anton Khirnov	9178235ffb	avfilter: mark start_frame/end_frame/draw_slice as deprecated 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	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
Stefano Sabatini	7945665200	lavfi: store and propagate number of channels information in audio buffer properties The channels field is required since the channel layout is not always available.	12 years ago
