Anton Khirnov	4a1ac8c43f	lavfi: move buffer management function to a separate file.	13 years ago
Anton Khirnov	4c64fed37c	lavfi: move formats-related functions from default.c to formats.c It's more convenient to have them all in one file.	13 years ago
Anton Khirnov	c5432d3ca4	lavfi: move video-related functions to a separate file. This is easier to follow than having them randomly scattered in avfilter.c and defaults.c.	13 years ago
Anton Khirnov	9f26421b0b	lavfi: add asyncts filter.	13 years ago
Anton Khirnov	fb604ae850	lavfi: add aformat filter Based on a patch by Mina Nagy Zaki <mnzaki@gmail.com>	13 years ago
Anton Khirnov	a2cd9be212	lavfi: add an audio buffer sink.	13 years ago
Anton Khirnov	4c66c40718	lavfi: add an audio buffer source.	13 years ago
Anton Khirnov	720c6b78d1	buffersrc: add av_buffersrc_write_frame(). It's the same as av_vsrc_buffer_add_frame(), except it doesn't take pts or pixel_aspect parameters. Those are read from AVFrame. Deprecate av_vsrc_buffer_add_frame().	13 years ago

Anton Khirnov	012f04a277	lavfi: autoinsert resample filter when necessary.	13 years ago
Anton Khirnov	d371e7b988	lavfi: add lavr-based audio resampling filter.	13 years ago
Anton Khirnov	0b45334a58	lavfi: move audio-related functions to a separate file. This is easier to follow than having them randomly scattered in avfilter.c and defaults.c.	13 years ago
Anton Khirnov	472fb3bbfa	lavfi: remove some audio-related function from public API. Those functions are only useful inside filters. It is better to not support user filters until the API is more stable. This breaks audio filtering API and ABI in theory, but since it's unusable right now this shouldn't be a problem.	13 years ago
Anton Khirnov	f20ab492ac	lavfi: change AVFilterLink.sample_rate from int64_t to int on next bump There is no real reason for it to be 64bit, it's just a plain int in the rest of Libav.	13 years ago
Anton Khirnov	a6bdfc2a92	lavfi: change AVFilterBufferRefAudioProps.sample_rate from uint32_t to int There's no reason for it to be explicitly 32 bits. It's declared as a plain int in all other places in Libav. This breaks audio filtering API and ABI in theory, but since it's unusable right now this shouldn't be a problem.	13 years ago
Stefano Sabatini	7ef0adcc2e	lavfi: simplify signature for avfilter_get_audio_buffer() and friends The additional parameters are just complicating the function interface. Assume that a requested samples buffer will always have the format specified in the requested link. This breaks audio filtering API and ABI in theory, but since it's unusable right now this shouldn't be a problem. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	6735534f19	lavfi: use avfilter_get_audio_buffer_ref_from_arrays() in avfilter_default_get_audio_buffer	13 years ago
Stefano Sabatini	e727bca392	lavfi: cleanup avfilter_get_audio_buffer() and pals. Remove AVFilterBufferRefAudioProps.size, and use nb_samples in its place everywhere. This is required as the size in the audio buffer may be aligned, so it may not contain a well defined number of samples. Also remove the useless planar parameter, which can be deduced from the sample format. This is technically an API and ABI break, but since the audio part of lavfi is not usable now, this should not be a problem in practice. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	1b8c9271bd	lavfi: add avfilter_get_audio_buffer_ref_from_arrays(). Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Anton Khirnov	9453c9e1de	lavfi: add extended_data to AVFilterBuffer. This is similar to what has previously been done in AVFrame to allow dealing with more than 8 channels.	13 years ago
Anton Khirnov	ac71230902	lavfi: add video buffer sink, and use it in avtools Also add the public interface libavfilter/buffersink.h. Based on a commit by Stefano Sabatini.	13 years ago
Anton Khirnov	ab165047a6	lavfi: add a function for copying properties from AVFilterBufferRef->AVFrame Based on a commit by Stefano Sabatini <stefano.sabatini-lala@poste.it>	13 years ago
Anton Khirnov	8134fafe9b	lavfi: uninline avfilter_copy_buffer_ref_props(). A nontrivial public function such as this should most certainly NOT be inline.	13 years ago
Diego Biurrun	dbe6ba55a3	build: cosmetics: Add missing end-of-line backslashes to item lists.	13 years ago
Diego Biurrun	9eb83a56aa	build: cosmetics: Split HEADERS/OBJS/PROGS lists into one entry per line.	13 years ago
Robert Nagy	a07578f3f2	vf_yadif: fix missing error handling for avfilter_poll_frame()	13 years ago
Anton Khirnov	0bbd874743	lavfi: support audio in avfilter_copy_frame_props().	13 years ago
Mina Nagy Zaki	11b6a82412	lavfi: avfilter_merge_formats: handle case where inputs are same This fixes a double-free crash if lists are the same due to the two merge_ref() calls at the end of the (useless) merging that happens. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Anton Khirnov	d4ac703c7f	lavfi/formats: use sizeof(var) instead of sizeof(type).	13 years ago
Stefano Sabatini	f10530b78a	lavfi: remove avfilter_default_config_input_link() declaration The function is not implemented (and possibly useless).	13 years ago
Anton Khirnov	25b3babe11	lavfi: always enable the scale filter and depend on sws. The scale filter is used for internal colorspace conversions, so it must always be present.	13 years ago
Anton Khirnov	fd18ee0ff6	vf_split: support user-specifiable number of outputs.	13 years ago
Nicolas George	5cb4f1a127	vsrc_buffer: return EAGAIN if no frame is available. This is not an erroneous condition, do not print a warning. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Anton Khirnov	aff01de641	graphparser: set next to NULL on an entry extracted from inputs list Prevents it from referring to the rest of the list.	13 years ago
Anton Khirnov	7af99a01c4	graphparser: fix the order in which unlabeled input links are returned.	13 years ago
Anton Khirnov	7bf9e3391f	vsrc_buffer: fix check from `7ae7c41`. The user submitted variable in this function is frame, not buf.	13 years ago
Stefano Sabatini	91d3cbe0fd	avfiltergraph: make the AVFilterInOut alloc/free API public This is required for letting applications to create and destroy AVFilterInOut structs in a convenient way. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Anton Khirnov	12e7e1d03e	graphparser: allow specifying sws flags in the graph description.	13 years ago
Anton Khirnov	4e781c25b7	graphparser: fix the order of connecting unlabeled links. Right now, e.g. scale,[in]overlay would connect scale to the first overlay input and [in] to the second, which goes against the documentation and is unintuitive. The bug happens because of the ordering mess in curr_inputs variable: 1) the unlabeled links from the previous filter are added to it in correct order 2) input labels are parsed and inserted to the beginning one by one (i.e. in reverse order) 3) curr_inputs is matched against filter inputs in reverse order Fix the problem by always using proper ordering without trying to be clever.	13 years ago
Anton Khirnov	d7bcc71dad	graphparser: add avfilter_graph_parse2(). Unlike avfilter_graph_parse(), it returns unlinked inputs and outputs to the caller, which allows parsing of graphs where inputs/outputs are not known in advance.	13 years ago
Anton Khirnov	7ae7c41413	vsrc_buffer: allow using a NULL buffer to signal EOF.	13 years ago
Anton Khirnov	e36b25d1df	vf_overlay: implement poll_frame() Signal that it can output a frame when there are frames on the main input and EOF on the overlay input, but a frame is buffered -- e.g. single picture overlay.	13 years ago
Anton Khirnov	90f65dc6cf	vf_scale: support named constants for sws flags.	13 years ago
