Pavel Koshevoy	a1aac8d004	lavfi: add atempo filter Add atempo audio filter for adjusting audio tempo without affecting pitch. This filter implements WSOLA algorithm with fast cross correlation calculation in frequency domain. Signed-off-by: Pavel Koshevoy <pavel@homestead.aragog.com> Signed-off-by: Stefano Sabatini <stefasab@gmail.com>	13 years ago
Stefano Sabatini	2b1fc5621d	lavfi: add asetnsamples audio filter This filter changes the number of samples on single output operation. Based on a patch by Andrey Utkin <andrey.krieger.utkin@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	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	d625136877	lavfi: add channelsplit audio filter.	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	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
Justin Ruggles	c7448c182a	lavfi: add audio mix filter	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
Justin Ruggles	afeb3590fc	lavfi: add an audio split filter Based on current version of the asplit filter in FFmpeg written by Stefano Sabatini and others.	13 years ago
Stefano Sabatini	150227e8ed	lavfi/asplit: move asplit code to vf_split.c, and make it support N outputs The move allows to share the init code already used by split.	13 years ago
Anton Khirnov	54c5dd89e3	lavfi: Add fps filter. Partially based on a patch by Robert Nagy <ronag89@gmail.com>	13 years ago
Stefano Sabatini	e1a8df70a2	lavfi/aevalsrc: add option channel_layout Allow to explicitly specify the channel layout to select.	13 years ago
Stefano Sabatini	4d4098da00	lavfi: drop planar/packed negotiation support The planar/packed switch and the packing_formats list is no longer required, since the planar/packed information is now stored in the sample format enum. This is technically a major API break, possibly it should be not too painful as we marked the audio filtering API as unstable.	13 years ago
Anton Khirnov	d89eca507c	Add missing version bumps and APIchanges/Changelog entries.	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
Nicolas George	440af105f2	lavfi: add avfilter_graph_set_auto_convert().	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	8134fafe9b	lavfi: uninline avfilter_copy_buffer_ref_props(). A nontrivial public function such as this should most certainly NOT be inline.	13 years ago
Stefano Sabatini	126ba1626e	lavfi/drawtext: give a new alias "timecode_rate" to the the r/rate option The option is related to the timecode, the new name clearly specifies the context. Also it allows to list the option close to the other timecode options.	13 years ago
Paul B Mahol	2cda0429aa	lavfi: remove screenshot libmpcodecs wrapper The filter is useless. Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	5f161c2357	lavfi/tinterlace: support symbolic names for the parameter Also deprecate the use of numerical values.	13 years ago
Stuart Morris	820c023142	lavfi/tinterlace: add tinterlace mode 6 This new mode is useful for generating frames for interlaced video displays. Typically interlaced video displays have no form of field synchronisation. This new mode guarantees correct field order without any requirement for field synchronisation. Signed-off-by: Stefano Sabatini <stefasab@gmail.com>	13 years ago
Nicolas George	e11110dee4	buffersink: add AV_BUFFERSINK_FLAG_NO_REQUEST.	13 years ago
Tim Nicholson	c97201dd29	lavfi/setfield: add "progressive" option Add "prog" parameter value, and deprecate numeric values. Signed-off-by: Stefano Sabatini <stefasab@gmail.com>	13 years ago
Stefano Sabatini	9750254885	lavfi/mp: remove libmpcodecs mirror filter The native libavfilter hflip filter does the same thing.	13 years ago
Robert Nagy	65fa7bc1f8	lavfi: add avfilter_unref_bufferp() Signed-off-by: Stefano Sabatini <stefasab@gmail.com>	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
Stefano Sabatini	5eeecde859	lavfi/mp: remove 2xsai wrapped filter It was ported to a native libavfilter filter.	13 years ago
Stefano Sabatini	b7a7830dd4	lavfi: port 2xsai filter from libmpcodecs Partially based on the port by Niel van der Westhuizen <nielkie@gmail.com>, done for GCI 2010. Same output as the original filter and as fast. See thread: Subject: [FFmpeg-devel] [PATCH] Port MPlayer 2xSaI filter to libavfilter Date: Thu, 25 Nov 2010 01:31:24 +1000	13 years ago
Stefano Sabatini	162e400464	lavfi: install asrc_abuffer.h header The header is part of the public API, in particular is used by doc/examples/filtering_audio.c.	13 years ago
Stefano Sabatini	6cb01c9dba	lavfi/mp: remove remove_logo wrapper removelogo has been ported to libavfilter, and the wrapper was not working.	13 years ago
Stefano Sabatini	2f83681c79	lavfi: port libmpcodecs remove-logo filter The code is based on the remove-logo filter in MPlayer/libmpcodecs, by Robert Edele, relicensed to LGPL with consent of the author. Address trac issue #249.	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	3225bc37a3	lavfi: add bbox filter Also add bbox.h and bbox.c files, based on the remove-logo filter by Robert Edele. These files are useful for sharing code with the pending removelogo port.	13 years ago
Stefano Sabatini	aefd1cb725	lavfi: remove swapuv libmpcodecs wrapper The filter has been ported to a native libavfilter filter.	13 years ago
Stefano Sabatini	fa35d880aa	lavfi: port MP swapuv filter	13 years ago

Clément Bœsch	c79eddaff1	lavfi/aconvert: use libswresample. This commit also drops the planar parameter; you now need to use the 'p' suffix in order to request a planar sample format.	13 years ago
Michael Niedermayer	c4bdb2bf93	libavfilter/version.h: fix project name The code in the file is written by vitor in `be19d752` (2008) thus cannot have originated in libav which did not exist at that time Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	0c3577bfd9	lavfi: add avfilter_graph_dump.	13 years ago
