|
||||
|
||||
will convert the input video to the format "yuv420p".
|
||||
|
||||
@section frei0r
|
||||
|
||||
Apply a frei0r effect to the input video.
|
||||
|
||||
To enable compilation of this filter you need to install the frei0r
|
||||
header and configure FFmpeg with --enable-frei0r.
|
||||
|
||||
The filter supports the syntax:
|
||||
@example
|
||||
@var{filter_name}:@var{param1}:@var{param2}:...:@var{paramN}
|
||||
@end example
|
||||
|
||||
@var{filter_name} is the name to the frei0r effect to load. If the
|
||||
environment variable @env{FREI0R_PATH} is defined, the frei0r effect
|
||||
is searched in each one of the directories specified by the colon
|
||||
separated list in @env{FREIOR_PATH}, otherwise in the standard frei0r
|
||||
paths, which are in this order: @file{HOME/.frei0r-1/lib/},
|
||||
@file{/usr/local/lib/frei0r-1/}, @file{/usr/lib/frei0r-1/}.
|
||||
|
||||
@var{param1}, @var{param2}, ... , @var{paramN} specify the parameters
|
||||
for the frei0r effect.
|
||||
|
||||
A frei0r effect parameter can be a boolean (whose values are specified
|
||||
with "y" and "n"), a double, a color (specified by the syntax
|
||||
@var{R}/@var{G}/@var{B}, @var{R}, @var{G}, and @var{B} being float
|
||||
numbers from 0.0 to 1.0) or by an @code{av_parse_color()} color
|
||||
description), a position (specified by the syntax @var{X}/@var{Y},
|
||||
@var{X} and @var{Y} being float numbers) and a string.
|
||||
|
||||
The number and kind of parameters depend on the loaded effect. If an
|
||||
effect parameter is not specified the default value is set.
|
||||
|
||||
Some examples follow:
|
||||
@example
|
||||
# apply the distort0r effect, set the first two double parameters
|
||||
frei0r=distort0r:0.5:0.01
|
||||
|
||||
# apply the colordistance effect, takes a color as first parameter
|
||||
frei0r=colordistance:0.2/0.3/0.4
|
||||
frei0r=colordistance:violet
|
||||
frei0r=colordistance:0x112233
|
||||
|
||||
# apply the perspective effect, specify the top left and top right
|
||||
# image positions
|
||||
frei0r=perspective:0.2/0.2:0.8/0.2
|
||||
@end example
