Anton Khirnov 77cc958f60 lavfi: add const to the AVFilter parameter of avfilter_graph_create_filter()

Anton Khirnov 129bb23843 lavfi: add a slice threading infrastructure 
Mostly based on libavcodec's
 2013-05-24 09:28:18 +02:00
Anton Khirnov bc8c1cdc7b lavfi doxy: add a page for lavfi. 2013-05-17 20:26:11 +02:00
Anton Khirnov fa2a34cd40 lavfi: change the filter registering system to match the other libraries 
Removes an arbitrary hardcoded limit on the number of filters.
 2013-04-11 20:44:03 +02:00
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.
 2013-04-11 20:43:47 +02:00
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.
 2013-04-11 20:42:41 +02:00
Anton Khirnov 1ba95a9cca lavfi: add avfilter_init_dict() for initializing a filter with a dict. 2013-04-11 20:40:20 +02:00
Anton Khirnov 48a5adab62 lavfi: add avfilter_init_str() to replace avfilter_init_filter(). 
Drop the unused opaque parameter from its signature.
 2013-04-11 20:39:13 +02:00
Anton Khirnov 1565cbc65c lavfi: make avfilter_free() remove the filter from its graph. 2013-04-11 20:38:48 +02:00
Anton Khirnov 111367263a lavfi: add AVFilterContext.graph. 
It will be useful in the following commits.
 2013-04-11 20:38:23 +02:00
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.
 2013-04-11 20:36:42 +02:00
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.
 2013-04-11 20:34:14 +02:00
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.
 2013-04-11 20:33:33 +02:00
Anton Khirnov 4a37d4b3f8 lavfi: add const to the pads parameter of avfilter_pad_get_name/type 2013-04-11 20:33:23 +02:00
Anton Khirnov 91d2efa7d6 lavfi: add const to AVFilterContext.filter. 
lavfi should never modify the filter through that pointer.
 2013-04-11 20:32:39 +02:00
Anton Khirnov 8114c10160 lavfi: add avfilter_get_class(). 
Useful for examining options, the same as the corresponding functions
for the other libs.
 2013-04-09 19:13:19 +02:00
Anton Khirnov c43a7ecad9 lavfi: remove now unused args parameter from AVFilter.init 2013-04-09 19:12:38 +02:00
Anton Khirnov 4fa1f52e33 af_resample: switch to an AVOptions-based system. 2013-04-09 18:45:50 +02:00
Anton Khirnov b439c992c2 lavfi: switch to an AVOptions-based system. 2013-04-09 18:45:37 +02:00
Anton Khirnov 7e350379f8 lavfi: switch to AVFrame. 
Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.
 2013-03-08 07:37:18 +01:00
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.
 2012-11-28 08:50:19 +01:00
Justin Ruggles a903f8f087 Include libavutil/channel_layout.h instead of libavutil/audioconvert.h 
Also reorder some other #include when applicable.

Anton Khirnov 1961e46c15 lavfi: remove disabled FF_API_FILTERS_PUBLIC cruft 2012-06-26 13:20:19 +02:00
Anton Khirnov 5e88b96f37 lavfi: remove disabled FF_API_DEFAULT_CONFIG_OUTPUT_LINK cruft 2012-06-26 13:18:44 +02:00
Anton Khirnov 6c1e065bd4 lavfi: remove disabled FF_API_SAMPLERATE64 cruft 2012-06-26 13:15:14 +02:00
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.
 2012-06-26 13:13:48 +02:00
Anton Khirnov f75be9856a lavfi: allow audio filters to request a given number of samples. 
This makes synchronization simpler for filters with multiple inputs.
 2012-06-22 21:23:42 +02:00
Anton Khirnov 58b049f2fa lavfi: support automatically inserting the fifo filter when needed. 
This breaks libavfilter ABI.
 2012-06-22 21:06:01 +02:00
Anton Khirnov 9baeff9506 lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputs 
This is more consistent with naming in the rest of Libav.
 2012-06-13 11:13:22 +02:00
Anton Khirnov 9d0bfc5052 lavfi: make AVFilterPad opaque after two major bumps. 
It will allow adding new fields to it without ABI breaks.
 2012-06-13 11:11:33 +02:00
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.
 2012-06-13 11:10:17 +02:00
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.
 2012-06-13 11:09:15 +02:00
Anton Khirnov 803391f719 lavfi: remove request/poll and drawing functions from public API on next bump

now.
 2012-06-05 09:38:16 +02:00
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.
