| | | | Signed-off-by: Stefano Sabatini <stefasab@gmail.com>
* doc/filters: drop duplicated description of resampler options in aresample docsStefano Sabatini2012-12-30
| | | | | Avoid duplication, and point to the complete description of options. Also provide a more complete specification of the supported syntax.
* doc/filters: remove outdated commentsStefano Sabatini2012-12-24
| | | | | Audio API should not be considered unstable any longer, and mentioning VHOOK is confusing, as it was removed 4 years ago.

* lavfi: add pp filter.Clément Bœsch2012-12-23
| | | | | | | | | | | Ported from MPlayer. Original author is A'rpi, with various contributions from Michael Niedermayer. The original documentation was mostly written by Diego Biurrun. See the MPlayer history for full credits. The filter is under GPL like the original filter, even if it differs quite a lot. There is not much point in making it LGPL since pp is under GPL.

* doc/filters: reword introduction sentence of aformat.Clément Bœsch2012-12-22
|
* doc/filters: simplify escaping in aformat.Clément Bœsch2012-12-22
| | | | | Escaping the '=' is not necessary, and quoting the arguments allow to remove the comma escaping as well.
* doc/filters: add overlay daisy-chaining exampleStefano Sabatini2012-12-22
|
* doc/filters: rework and itemize examples for the overlay filterStefano Sabatini2012-12-22

* doc/filters: rename reference to movie filter from "src_movie" to "movie"Stefano Sabatini2012-12-22
| | | | Should be less confusing.
* doc: remove mention of fifo filter in the introduction.Clément Bœsch2012-12-19
| | | | It's confusing and not necessary, especially in the introduction.
* doc/filters: reformat and rework gradfun.Clément Bœsch2012-12-19
| | | | Note that examples are changed.
* lavfi/gradfun: support named options.Clément Bœsch2012-12-19
| | | | This breaks usage for out-of-range values.
* lavfi/gradfun: reduce up limit for threshold.Clément Bœsch2012-12-19
| | | | | | | | | | This will prevent an overflow in the SSSE3 and MMX filter_line code: delta is expressed as an u16 being shifted by 2 to the left. If it overflows, having a strength not above 64 will make sure that m is set to 0 (making the m*m*delta >> 14 expression void). A value above 64 should not make any sense unless gradfun is used as a blur filter.
* avfilter: add apad filterMichael Niedermayer2012-12-18
| | | | | | | | This filter pads an audio stream with silence It can together with -shortest be used to extend audio streams to the same length as video. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
