Nicolas George	a7ac05ce2f	src_movie: implement multiple outputs. The audio and video code paths were too different, most of the decoding has been rewritten.	13 years ago
Nicolas George	612307978d	lavfi: change "transmedia" into "multimedia".	13 years ago
Nicolas George	be33da9a1d	lavfi: add concat filter.	13 years ago
Steven Robertson	82ecae8a70	lavfi: add alphaextract and alphamerge filters These filters are designed for storing and transmitting video sequences with alpha using higher-efficiency codecs such as x264 which don't natively support an alpha channel. 'alphaextract' takes an input stream with an alpha channel and returns a video containing just the alpha component as a grayscale value; 'alphamerge' takes an RGB or YUV stream and adds an alpha channel recovered from a second grayscale stream.

Stefano Sabatini	bd58f00ec1	doc/filters: prefer "special" over "magic" for special input/output labels	13 years ago
Stefano Sabatini	b65ccce866	doc/filters: update documentation In particular, assume existence of audio and sink filters.	13 years ago
Stefano Sabatini	5a6c7a218c	doc: merge libavfilter.texi into filters.texi There is no much point into splitting documentation for filters. Also having a separate document for a library is inconsistent.	13 years ago
Nicolas George	ba856c0be5	lavfi: implement asettb filter.	13 years ago
Anton Khirnov	7a8059eb9c	doc/filters: fix typo.	13 years ago
Alex Converse	41e637e449	lavfi: Add the af_channelmap audio channel mapping filter. Inspired by MPlayer's af_channels filter and SoX's remix effect.	13 years ago
Anton Khirnov	dc07fb6f7b	lavfi: add join audio filter. It joins multiple input streams into one multi-channel output.	13 years ago
Stefano Sabatini	3ea3e32e03	lavfi: add showwaves filter	13 years ago
Paul B Mahol	9e7543361c	lavfi/color: use AVOptions Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Clément Bœsch	20a6fa77a6	doc: add two similar overlay "side-by-side" examples.	13 years ago
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.

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
Stefano Sabatini	b6131ac5d3	doc/filters: prefer @itemize environment for frei0r examples	13 years ago
Stefano Sabatini	eb732b2ade	doc/filters: update Frei0r website link Frei0r recently changed website host.	13 years ago
Anton Khirnov	d625136877	lavfi: add channelsplit audio filter.	13 years ago
Nicolas George	9ca440679d	buffersrc: accept the frame rate as argument.	13 years ago
Nicolas George	dcaa4efcee	buffersrc: accept key=value arguments. The current flat arguments syntax is not easily extensible due to sws_param possibly containing commas. This is also consistent with abuffersrc.	13 years ago
Nicolas George	e0545262a2	amerge: accept multiple inputs.	13 years ago
Clément Bœsch	72868144e5	lavfi/select: add scene detection. Based on the shotdetect algorithm (http://shotdetect.nonutc.fr/ by Johan MATHE johan.mathe tremplin-utc.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	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	d371e7b988	lavfi: add lavr-based audio resampling filter.	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	fd18ee0ff6	vf_split: support user-specifiable number of outputs.	13 years ago
Stefano Sabatini	20f47eb574	doc/filters: consistently use '"' for quoting the drawtext arguments in examples	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
Stefano Sabatini	4f19e50c23	doc/filters: document drawtext draw expression	13 years ago
Stefano Sabatini	56b39bd55d	doc/filters: document rand() drawtext expression function	13 years ago

Stefano Sabatini	730af6e617	doc/filters: fix location of "rate" and "timecode" drawtext options They are options, not expression parameters.	13 years ago
