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
Clément Bœsch	3f80546d75	lavfi/drawbox: fix width displayed in place of x.	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

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
Reimar Döffinger	6458a08700	vf_scale: ensure the palette is set for output. Since those are pseudo-palette formats, swscale does not write into data[1], swscale must initialize the palette properly itself. This lead to frames that actually decoded as all-gray before. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	24eac3cff5	Mark GRAY8 format as pseudo-paletted. This fixes that the GIF encoder crashes with it because it has no palette. And the arguments for the pseudopalette apply to gray8 as much as to RGB8 etc. In addition the changes required in lavfi should be needed anyway when adding support for RGB8 etc. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	bbaf941e29	scale: fix slice rendering with conversion between pal/non-pal. We can't use whether the input format is paletted to decide that the output format has a palette in data[1], too, that makes no sense. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	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	95587d29d7	vsrc_buffer: allow buffering arbitrary number of frames.	13 years ago
Anton Khirnov	416fd90ead	vf_scale: avoid a pointless memcpy in no-op conversion. I.e. just pass the buffer along when src parameters == dst parameters.	13 years ago
Anton Khirnov	63736fe48c	avfiltergraph: try to reduce format conversions in filters. Current code, with a filterchain such as (input - yuv411) -> (scale - any) -> (sink - any) will result in yuv420 being chosen for the second link, which is clearly not right. This commit attempts to improve in the following way: repeat until convergence: loop over all filters find input link with exactly one format force this format on all output links of the same type (if possible)	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
