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.
