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	556aab8f11	lavfi: use designated initializers in avfilter_class	12 years ago

Michael Niedermayer	212b89f8b4	avfilter: remove unused variable Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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

Stefano Sabatini	e47114d545	lavfi: increment max number of registered filters from 128 to 256 The total number of implemented filters is already over 128.	12 years ago
Xi Wang	eb553096e5	lavfi: fix null checking in avfilter_config_links() Move the first use of `link' after the null pointer check. Signed-off-by: Xi Wang <xi.wang@gmail.com> Reviewed-by: Stefano Sabatini <stefasab@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	ff6b34009d	lavfi: fix use-after-free in ff_filter_frame. Unlike the original ff_start_frame code, the incoming reference may be freed before that point. Fix CID966654.	12 years ago
Nicolas George	82541d8330	lavfi: merge all filtering code into ff_filter_frame.	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
Nicolas George	0146c1f0f1	lavfi: remove init and check of rate and layout. The sample rate and channel layout are negotiated and set by the filter graph system.	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	f6dd145533	avfilter: check that filter_frame and slice variants are not both used 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
Anton Khirnov	59ee9f78b0	lavfi: do not use av_pix_fmt_descriptors directly.	13 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	13 years ago
Mans Rullgard	1fce361d70	lavfi: replace empty input/output lists with null pointers Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Stefano Sabatini	34bf06a35c	lavfi: when configuring a link, set channel layout from previous link if unspecified In avfilter_config_links(), if the current channel layout is not specified, set the same value of the previous link in the filterchain. Consistent with the logic used to set the other link parameters.	13 years ago
Nicolas George	c2271fa7f9	lavfi: free partial audio buffers when destroying links. Fix a memleak that the recent change of architecture made more likely to happen.	13 years ago
Nicolas George	beeba9161a	lavfi: add a closed field to AVFilerLink. It will help forward errors and maintain consistency.	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
Stefano Sabatini	5c0d8bc4ce	lavfi: add avfilter_get_class() and iteration callbacks Allow iteration over filter options.	13 years ago
Diego Biurrun	49c45a2624	avfilter: Fix printf format string conversion specifier libavfilter/avfilter.c:224:9: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 5 has type ‘int’ [-Wformat]	13 years ago
Nicolas George	d06bfda07e	lavfi: rescale link->current_pts. The doxy says, and the heap implementations assumes, it is in AV_TIME_BASE units.	13 years ago
Stefano Sabatini	21d5609826	lavfi: add init_opaque callback This will be used by filters which require an opaque field to be passed in input. Should be required only for filters which imply a programmatic use. This is possibly a temporary solution, to be removed when we'll have a clearer and better agreememnt of how/if to pass binary data for initializing a filter. See thread: Subject: [FFmpeg-devel][PATCH] lavfi: add init2 callback Date: Fri, 6 Jul 2012 01:22:17 +0200	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	1a49a169eb	lavfi: make filters less verbose.	13 years ago
Anton Khirnov	1961e46c15	lavfi: remove disabled FF_API_FILTERS_PUBLIC cruft	13 years ago
Anton Khirnov	5e88b96f37	lavfi: remove disabled FF_API_DEFAULT_CONFIG_OUTPUT_LINK cruft	13 years ago
Anton Khirnov	205e90249a	lavfi: use proper FF_API guards for different deprecated functions	13 years ago
Anton Khirnov	a5e8c41c28	lavfi: remove 'opaque' parameter from AVFilter.init() It is not used in any filters currently and is inherently evil. If passing binary data to filters is required in the future, it should be done with some AVOptions-based system.	13 years ago
Nicolas George	bd9939f495	lavfi: display pad type with mismatch error message.	13 years ago
Michael Niedermayer	0412e5187e	lavfi/avfilter: use av_assert Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Paul B Mahol	54101214d8	lavfi: use designated initializers for AVClass While here: - add missing .version and .category, - make .class_name consistent across filters, - align declarations. Signed-off-by: Paul B Mahol <onemda@gmail.com>	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	84b9fbe055	lavfi: add avfilter_pad_get_type() and avfilter_pad_get_name(). This will allow making AVFilterPad opaque for the calling apps, since those are the only two fields that can be useful to the users.	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
Alex Converse	65a80ee1ec	avfilter: Log an error if avfilter fails to configure a link.	13 years ago
Stefano Sabatini	ee1748ab53	lavfi: fix signature for default_filter_name() Return a const char *, fix warnings: libavfilter/avfilter.c: In function ‘default_filter_name’: libavfilter/avfilter.c:414:5: warning: return discards ‘const’ qualifier from pointer target type [enabled by default] libavfilter/avfilter.c: At top level: libavfilter/avfilter.c:419:5: warning: initialization from incompatible pointer type [enabled by default] libavfilter/avfilter.c:419:5: warning: (near initialization for ‘avfilter_class.item_name’) [enabled by default]	13 years ago
Nicolas George	7b42036b3b	lavfi: add a frame_rate field to AVFilterLink.	13 years ago
Stefano Sabatini	ad347bf459	lavfi: remove avfilter_default_item_name() from public API The function was introduced in `4d6a8a2bdb` and is not used anymore outside avfilter.c. This avoids to pollute the public API with an apparently unnecessary function. The function was introduced a few days ago, so removing it from the public API should do no much harm.	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
