qc2movie -- Quartz Composer export tool
qc2movie inCompositionPath|repositoryCompositionIdentifier outMoviePath width height duration [--parameterKey1 value1 ...]
qc2movie is a tool that exports a Quartz Composer composition into a QuickTime movie by adding a track containing this composition. It is the
command line equivalent of exporting a composition for the Quartz Composer application to a QuickTime movie.
specifies which composition you want to export. Ar inCompositionPath is the path to the composition. Ar reposito-
ryCompositionIdentifier is the identifier of a composition which lies in the Quartz Composer Repository.
outMoviePath specifies movie file path to which the composition will be exported to
width defines the width of the export movie
height defines the height of the export movie
duration defines the length of the export movie
[--parameterKey1 value1 ...]
passes composition specific parameters through the command line tool to the composition
EXAMPLES -To create a 10 second QuickTime movie containing a Quartz Composer track of the Particle System composition:
qc2movie "/Developer/Examples/Quartz Composer Compositions/Particle Systems/Particle System.qtz" ~/example.mov 640 480 10
-To merge two video tracks (30s each) together using an image transition protocol abiding composition (Swing for example) in the Quartz
Composer Repository (using its identifier: /swing):
qc2movie /swing ~/merged-example.mov 640 480 60 --inputMoviePath1 ~/firstVideo.mov --inputMoviePath2 ~/secondVideo.mov --duration 2
-To apply an image filter protocol abiding composition to the video track of a movie:
qc2movie /colorpencil ~/effect-example.mov 640 480 30 --input ~/Video.mov

SWF::VideoStream - SWF Video class
$videostream = new SWF::VideoStream("test.flv");
SWF::VideoStream is a helper class useful for playing videos via SWF applications, either via embedded video data, or controlled by
$videostream = new SWF::VideoStream($filename)
Creates a SWF::VideoStream object. If the file can't be opened the constructor will return an empty object. The filename is not limited
to 'flv' extension.
$frames = $videostream->getNumFrames()
This method returns the number of video-frames of an object of SWF::VideoStream, this works only for embedded streams. In case of error
you will get result of -1.
This method sets width and height for streamed videos, this works only on streamed videos (progressive download or rtmp).
$bool = $videostream->hasAudio()
A test whether the embedded FLV stream also has audio data.
If the mode == SWFVIDEOSTREAM_MODE_AUTO (default) on every SWF movie frame a video frame is added. In SWFVIDEOSTREAM_MODE_MANUAL mode,
the user needs to call the nextFrame() method to change the video's frame. This works only with embedded video streams. Does return
the previous mode or -1 if an invalid mode was passed.
$result = $videostream->nextFrame()
Switch to next video frame. Works only with embedded video streams. Returns -1 if an error happend. Here follows some demo code how to
use SWF::VideoStream objects (without ActionScript):
use SWF qw(:ALL); # to be lazy
$movie = new SWF::Movie();
$movie->setRate( 25 );
# $movie->setRate( 5 ); # e.g. 5 for slow motion
# here movie set background etc. etc.
die if (-1 == $v->getNumFrames()); # abort if something went wrong
$video->seek(1000, 0); # for example only
$displayitem = $movie->add($video);
# 250 for a 10 seconds movie part (at rate of 25 per minute)
for(my $n = 0; $n < 250; ++$n)
# that's all, folks
$result = $videostream->seek($frame, $whence)
This functions allows seeking $frame in video stream, returning the old video frame position. As value of $whence use one of the
0 for seeking from beginning
1 for seeking from current position
2 for seeking from end of file
