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	7950e519bb	Disable deprecation warnings for cases where a replacement is available	12 years ago
Anton Khirnov	129bb23843	lavfi: add a slice threading infrastructure Mostly based on libavcodec's	12 years ago
Anton Khirnov	b01f6041f4	lavfi: rename AVFilterFormats.format_count to nb_formats This is more consistent with naming in the rest of Libav.	12 years ago
Anton Khirnov	096696ef0d	avfiltergraph: simplify inserting conversion filters. There is now no need to explicitly pass 0:0 as width/height to scale, those are the defaults.	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	6d0546bbaf	avfiltergraph: set deprecated filter_count.	12 years ago
Anton Khirnov	6e3c13a559	avfiltergraph: check for sws opts being non-NULL before using them. Avoid snprintfing a NULL pointer. CC: libav-stable@libav.org	12 years ago
Anton Khirnov	dd74e3ef33	avfiltergraph: use sizeof(var) instead of sizeof(type)	12 years ago
Anton Khirnov	42c7c61ab2	avfiltergraph: replace AVFilterGraph.filter_count with nb_filters This is more consistent with the naming in the rest of Libav.	12 years ago
Reimar Döffinger	efa7f42020	Use the avstring.h locale-independent character type functions Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Justin Ruggles	9f1223562e	lavfi: connect libavresample options to af_resample via AVFilterGraph	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
Anton Khirnov	e3496e5dbe	avfiltergraph: silence an uninitialized variable warning The warning is: libavfilter/avfiltergraph.c: In function ‘avfilter_graph_config’: libavfilter/avfiltergraph.c:528:9: warning: ‘best_idx’ may be used uninitialized in this function [-Wuninitialized] libavfilter/avfiltergraph.c:479:13: note: ‘best_idx’ was declared here Initialize it to an invalid value and add an assert that it's properly set later.	12 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Justin Ruggles	743f07062a	lavfi: better channel layout negotiation Allow substitution of channel pairs in the input for nearby channel pairs in the output in order to get a closer match. Also weigh LFE channel mismatch differently to favor matching the same layout without LFE over one less channel with LFE.	13 years ago
Anton Khirnov	61d158c321	avfiltergraph: shut up uninitialized variable warning. The warning silenced was: libavfilter/avfiltergraph.c: In function ‘avfilter_graph_config’: libavfilter/avfiltergraph.c:500:13: warning: ‘best_idx’ may be used uninitialized in this function [-Wuninitialized]	13 years ago
Anton Khirnov	8d900aa4d0	lavfi: remove disabled FF_API_GRAPH_AVCLASS cruft	13 years ago
Anton Khirnov	58b049f2fa	lavfi: support automatically inserting the fifo filter when needed. This breaks libavfilter ABI.	13 years ago
Anton Khirnov	24b2f4ed21	avfiltergraph: remove a redundant call to avfilter_get_by_name().	13 years ago
Anton Khirnov	2f296e39a1	lavfi: allow building without swscale.	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	b74a1da49d	lavfi: make formats API private on next bump. It is 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
Anton Khirnov	43c7a01e98	lavfi: remove avfilter_default_* from public API on next bump. Those functions are only useful inside filters. It is better to not support user filters until the API is more stable.	13 years ago
Anton Khirnov	ccefa89f39	avfiltergraph: smarter sample format selection.	13 years ago
Anton Khirnov	fd127ede62	avfiltergraph: reindent	13 years ago
Anton Khirnov	ff1f51a8aa	lavfi: add channel layout/sample rate negotiation.	13 years ago
Anton Khirnov	012f04a277	lavfi: autoinsert resample filter when necessary.	13 years ago
Anton Khirnov	63736fe48c	avfiltergraph: try to reduce format conversions in filters. Current code, with a filterchain such as (input - yuv411) -> (scale - any) -> (sink - any) will result in yuv420 being chosen for the second link, which is clearly not right. This commit attempts to improve in the following way: repeat until convergence: loop over all filters find input link with exactly one format force this format on all output links of the same type (if possible)	13 years ago
Anton Khirnov	996f9f0c32	avfiltergraph: add an AVClass to AVFilterGraph on next major bump. It will be used for logging, possibly also AVOptions.	13 years ago
Stefano Sabatini	57fa314090	lavfi: fix signature for avfilter_graph_parse() and avfilter_graph_config() Require "void " rather than "AVClass " for the log context type. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	59cef18c24	avfiltergraph: use meaningful error codes Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Stefano Sabatini	4359288c56	Make avfilter_graph_free() free the graph. Make avfilter_graph_free() free not only the internal structures, but also the allocated graph, and set the graph pointer to NULL for increased safety. Simplify usage. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Stefano Sabatini	caeb0c3027	Make avfilter_graph_free() do nothing if graph is NULL. Originally committed as revision 26323 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	b59dd1ea4f	Fix style nits in avfiltergraph.c. Originally committed as revision 26116 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	037be76e15	Add avfilter_graph_create_filter(). Originally committed as revision 25862 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	3fa77bde1b	In libavfilter, use consistently "Copyright (c)" in the license headers. Originally committed as revision 25838 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	4fcbb2af33	Prefix with "ff_" the functions: ff_avfilter_graph_check_validity() ff_avfilter_graph_config_links() ff_avfilter_graph_config_formats() and move their declaration to internal.h. These functions are never used in application code, so it is better to consider them internal functions, this can be changed later if necessary. Simplify API. Originally committed as revision 25737 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	24de0edbd5	Rename avfilter_destroy() as avfilter_free(). The new name is shorter and more consistent with the FFmpeg API, and sounds less evil. Originally committed as revision 25707 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	97dd1e4a87	Rename avfilter_graph_destroy() to avfilter_graph_free(). The new name is shorter and more consistent with the rest of the API. This change breaks libavfilter API/ABI. Originally committed as revision 25674 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	e15aeea656	Implement avfilter_graph_alloc(). Originally committed as revision 25673 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	2a24df9357	Add avfilter_graph_config(). Originally committed as revision 25502 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
