Stefano Sabatini	a4cb0af945	lavfi: drop deprecated and pointless avfilter_default_end_frame() function Fix warning when compiling boxblur. While this is technically a major API break, practically there will be no one using that function since the filtering API is mostly private, so that function alone is not usable.	12 years ago
Michael Niedermayer	91141f2a13	lavfi: add qp_table_size This avoid recalculating it and in case w/h changed avoids crashes. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	c9a0f9bf3c	libavfilter: pass QP table through the filter chain Any volunteers to port the pp and spp filters from libmpcodec? Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	beeba9161a	lavfi: add a closed field to AVFilerLink. It will help forward errors and maintain consistency.	12 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.	12 years ago
Stefano Sabatini	5c0d8bc4ce	lavfi: add avfilter_get_class() and iteration callbacks Allow iteration over filter options.	12 years ago
Nicolas George	8d6eed7b56	lavfi: document the constraints on incoming frames.	12 years ago
Nicolas George	8ef740ce01	lavfi: use a new field for automatic buffer copy. The code currently use cur_buf as the target of the copy, but cur_buf can be cleared by the filter if it has given the reference away or stored it elsewhere as soon as start_frame. The code still relies on the fact that the reference is not destroyed until end_frame. All filters currently follow that condition. An av_assert1() is added to check it; it should at least cause very visible errors in valgrind.	12 years ago
Michael Niedermayer	dfd8f2ff19	avfilter: fix minor typo Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Stefano Sabatini	e564de26b3	lavfi/avfilter.h: add doxy for AVFilterLink.out_buf	12 years ago
Stefano Sabatini	b73be80d48	lavfi/avfilter.h: add doxy for AVFilterLink.cur_buf	12 years ago

Anton Khirnov	ebc8d97481	lavfi: add error handling to start_frame().	13 years ago
Robert Nagy	b70d89a033	lavfi: add avfilter_unref_bufferp() Signed-off-by: Anton Khirnov <anton@khirnov.net>	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
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	83ba22392d	lavfi: reorder AVFilterLink fields. Move private fields to the private section, remove holes.	13 years ago
Anton Khirnov	f892013ac4	lavfi: reorder AVFilterContext fields. Place related fields together, remove holes.	13 years ago
Anton Khirnov	9618080512	lavfi: reorder AVFilter fields. Place related fields together, remove holes, move private fields to the end and mark them as private.	13 years ago
Anton Khirnov	f14e685609	lavfi: reorder AVFilterBufferRef fields. Place related fields together, remove holes.	13 years ago
Anton Khirnov	cb81e29138	lavfi: reorder AVFilterBuffer fields. Place related fields together, remove holes.	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	6c1e065bd4	lavfi: remove disabled FF_API_SAMPLERATE64 cruft	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
Stefano Sabatini	720ec62012	lavfi: drop deprecated and disabled packing API It was deprecated and removed after the recent 2->3 major bump.	13 years ago
Stefano Sabatini	8a3544149f	lavfi/avfilter.h: reorganize headers disposition Group lavfi headers together, slightly improve readability.	13 years ago
Stefano Sabatini	972cad77fa	lavfi: remove unnecessary inclusion of libavcodec/avcodec.h in avfilter.h libavfilter API was designed in order to be clarly distinguished from the libavcodec API, including avcodec.h in avfilter.h is not going to help to stick to this principle. The inclusion of libavutil/audioconvert.h in many files was required because avcodec.h includes audioconvert.h. libavfilter/avcodec.h is where the lavc/lavfi interface should be entirely placed.	13 years ago
Stefano Sabatini	a31ab50712	lavfi: move some FF_API_ definitions from avfilter.h to version.h version.h seems the right place for FF_API_ definitions.	13 years ago
Anton Khirnov	f75be9856a	lavfi: allow audio filters to request a given number of samples. This makes synchronization simpler for filters with multiple inputs.	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
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
Anton Khirnov	6d58358a3a	lavfi: make avfilter_get_video_buffer() private on next bump. They are only useful inside filters and we don't allow user filters for now.	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
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	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
Stefano Sabatini	4d6a8a2bdb	lavfi: add avfilter_default_filter_name() The function is modelled after av_default_item_name(), and will print the name of the instance filter if defined, otherwise the name of the filter. This allows to show the instance name in the log, which is useful when debugging complex filter graphs.	13 years ago
Anton Khirnov	0ce4a627c9	lavfi: fix comment, audio is supported now.	13 years ago
Anton Khirnov	ce353a881f	lavfi: fix incorrect comment. poll_frame()/request_frame() are used for audio too.	13 years ago
Anton Khirnov	c04c533f62	lavfi: remove avfilter_null_* 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	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
Mina Nagy Zaki	88c3b87bd8	lavfi: deprecate default config_props() callback and refactor avfilter_config_links() Link properties have to be checked after config_props() is called to make sure everything is sane, so the default config_props() for output links was redundant. Remove now empty defaults.c Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Nicolas George	5ac9ef6493	avfilter: make AVFilterFormats compatible with libav. The list goes back to being simple integers, and avfilter_make_format64_list is fixed to work with the correct structure directly.	13 years ago
Nicolas George	9567f410aa	avfilter: move some fields in AVFilterLink. It restores ABI compatibility with libav. The fields that move were very recent or morally private.	13 years ago
