Below is a description of the currently available multimedia filters.
@section asendcmd, sendcmd
Send commands to filters in the filtergraph.
These filters read commands to be sent to other filters in the
filtergraph.
@code{asendcmd} must be inserted between two audio filters,
@code{sendcmd} must be inserted between two video filters, but apart
from that they act the same way.
The specification of commands can be provided in the filter arguments
with the @var{commands} option, or in a file specified by the
@var{filename} option.
These filters accept the following options:
@table @option
@item commands, c
Set the commands to be read and sent to the other filters.
@item filename, f
Set the filename of the commands to be read and sent to the other
filters.
@end table
@subsection Commands syntax
A commands description consists of a sequence of interval
specifications, comprising a list of commands to be executed when a
particular event related to that interval occurs. The occurring event
is typically the current frame time entering or leaving a given time
interval.
An interval is specified by the following syntax:
@example
@var{START}[-@var{END}] @var{COMMANDS};
@end example
The time interval is specified by the @var{START} and @var{END} times.
@var{END} is optional and defaults to the maximum time.
The current frame time is considered within the specified interval if
it is included in the interval [@var{START}, @var{END}), that is when
the time is greater or equal to @var{START} and is lesser than
@var{END}.
@var{COMMANDS} consists of a sequence of one or more command
specifications, separated by ",", relating to that interval. The
syntax of a command specification is given by:
@example
[@var{FLAGS}] @var{TARGET} @var{COMMAND} @var{ARG}
@end example
@var{FLAGS} is optional and specifies the type of events relating to
the time interval which enable sending the specified command, and must
be a non-null sequence of identifier flags separated by "+" or "|" and
enclosed between "[" and "]".
The following flags are recognized:
@table @option
@item enter
The command is sent when the current frame timestamp enters the
specified interval. In other words, the command is sent when the
previous frame timestamp was not in the given interval, and the
current is.
@item leave
The command is sent when the current frame timestamp leaves the
specified interval. In other words, the command is sent when the
previous frame timestamp was in the given interval, and the
current is not.
@end table
If @var{FLAGS} is not specified, a default value of @code{[enter]} is
assumed.
@var{TARGET} specifies the target of the command, usually the name of
the filter class or a specific filter instance name.
@var{COMMAND} specifies the name of the command for the target filter.
@var{ARG} is optional and specifies the optional list of argument for
the given @var{COMMAND}.
Between one interval specification and another, whitespaces, or
sequences of characters starting with @code{#} until the end of line,
are ignored and can be used to annotate comments.
A simplified BNF description of the commands specification syntax
follows:
@example
@var{COMMAND_FLAG} ::= "enter" | "leave"
@var{COMMAND_FLAGS} ::= @var{COMMAND_FLAG} [(+|"|")@var{COMMAND_FLAG}]
@var{COMMAND} ::= ["[" @var{COMMAND_FLAGS} "]"] @var{TARGET} @var{COMMAND} [@var{ARG}]
@var{COMMANDS} ::= @var{COMMAND} [,@var{COMMANDS}]
@var{INTERVAL} ::= @var{START}[-@var{END}] @var{COMMANDS}
@var{INTERVALS} ::= @var{INTERVAL}[;@var{INTERVALS}]
@end example
@subsection Examples
@itemize
@item
Specify audio tempo change at second 4:
@example
asendcmd=c='4.0 atempo tempo 1.5',atempo
@end example
@item
Specify a list of drawtext and hue commands in a file.
@example
# show text in the interval 5-10
5.0-10.0 [enter] drawtext reinit 'fontfile=FreeSerif.ttf:text=hello world',
[leave] drawtext reinit 'fontfile=FreeSerif.ttf:text=';
# desaturate the image in the interval 15-20
15.0-20.0 [enter] hue reinit s=0,
[enter] drawtext reinit 'fontfile=FreeSerif.ttf:text=nocolor',
[leave] hue reinit s=1,
[leave] drawtext reinit 'fontfile=FreeSerif.ttf:text=color';
# apply an exponential saturation fade-out effect, starting from time 25
25 [enter] hue s=exp(t-25)
@end example
A filtergraph allowing to read and process the above command list
stored in a file @file{test.cmd}, can be specified with:
@example
sendcmd=f=test.cmd,drawtext=fontfile=FreeSerif.ttf:text='',hue
@end example
@end itemize
@section asetpts, setpts
Change the PTS (presentation timestamp) of the input frames.
