Stefano Sabatini	8fb03b4d70	lavfi: port tinterlace filter from MPlayer Port MPlayer tinterlace filter from MPlayer, with some ideas taken from the FFmbc/libavfilter port, with the following main differences: * added support for full-scale YUVJ formats * added support for YUVA420P * request_frame() on the filter is forced to return a frame * some code factorization (related to the copy_picture_fields() function) * fixed black padding values for mode 3	13 years ago
Stefano Sabatini	549b53e8cb	lavfi: remove redundant definition of avfilter_copy_frame_props() in avfilter.h Rationale: avfilter_copy_frame_props() was already defined in libavfilter/avcodec.h, and keeping the lavc/lavfi API glue localized in a specific file should ease maintainance and help the ones which use libavfilter without depending on libavcodec.	13 years ago

Mans Rullgard	cc276c85d1	Make channel layout masks unsigned It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Clément Bœsch	1fbf7165d5	lavfi: reimplement MPlayer's af_pan filter for libavfilter. Original code by Clément Bœsch. Parameters parsing and misc enhancements by Nicolas George.	13 years ago

Stefano Sabatini	1f4652068e	lavfi: rewrite nullsrc using the code in vsrc_testsrc.c Factorize code, extend the functionality of the filter, and make it return empty buffers. This is useful for filters which ignore the input frames content. This is also changing the syntax of the nullsrc source, and dropping the framerate expression evaluation, which does not look particularly useful.	13 years ago

Stefano Sabatini	171868e25a	lavfi: add negate filter This filter is a simple wrapper around the LUT filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	8fe0c527f3	lavfi: add LUT (LookUp Table) generic filters Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	f63ec3eee9	lavfi: fix FF_API_* definition macros Fix ABI break occurred after their use. Bug reported and patch provided by chinsou, fix trac issue #516, +80cola for me.	13 years ago
Stefano Sabatini	46b29397a6	vf_scale: add a "sar" variable Also create a "dar" alias for the "a" variable, for avoiding possible confusion between dar/sar. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	57fa314090	lavfi: fix signature for avfilter_graph_parse() and avfilter_graph_config() Require "void " rather than "AVClass " for the log context type. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Stefano Sabatini	482ce0ce4e	vf_drawtext: make x and y options parametric Address trac issue #378.	13 years ago
Stefano Sabatini	163854bca0	vf_drawtext: drop text wrapping feature Or in other word, do not go to the next line when the text cannot be rendered within the frame. The rationale is that wrapping is hard to manage, as it depends on the position of the text, thus making hard/impossible to compute the size occupied by the rendered text, and makes the filter behavior unpredictible with moving text (implemented in a pending patch). Also the current wrapping code is very limited (for example it splits words in the middle), and correctly handling wrapping requires much more complexity (alignment, gravity, word parsing etc.), while drawtext is meant to be only a thin wrapper around libfreetype, so such advanced features don't belong here.	13 years ago
Stefano Sabatini	b87d4c2b9f	vf_drawtext: do not set limitations on fontsize It may be needed to use values greater than 72, and in general greater than an arbitrary big value. Let the user choose what's too big for her.	13 years ago
Clément Bœsch	46c9ddf83c	lavfi: fix avfilter_get_audio_buffer() doxy to match reality.	13 years ago
Stefano Sabatini	e72aa524d8	asrc_anullsrc: implement a request_frame callback for returning frames This is mainly useful for filters (like the sox synth), which overwrite the content of the passed data.	13 years ago
Stefano Sabatini	44ab77db9e	asrc_anullsrc: extend syntax to make it accept a non positional list of arguments The new syntax is more extensible and more user-friendly. This breaks the previous syntax, should not be an issue as possibly no-one is already using anullsrc.	13 years ago
Stefano Sabatini	d763fb7d47	lavfi: add select filter Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
