NAME

       SWF::VideoStream - SWF Video class

SYNOPSIS

               use SWF::VideoStream;
               $videostream = new SWF::VideoStream("test.flv");

DESCRIPTION

       SWF::VideoStream is a helper class useful for playing videos via SWF applications, either
       via embedded video data, or controlled by ActionScript.

METHODS

       $videostream = new SWF::VideoStream($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.

       $videostream->setDimension(width, height)
           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.

       $videostream->setFrameMode($mode)
           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.
                   #
                   $video=new SWF::VideoStream('MyTestVideo.flv');
                   die if (-1 == $v->getNumFrames());      # abort if something went wrong
                   #
                   $video->setFrameMode(SWF::Constants::SWFVIDEOSTREAM_MODE_MANUAL);
                   $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)
                   {
                    $video->nextFrame();
                    $movie->nextFrame();
                   }
                   $movie->save("MyTestVideo.swf",9);
                   # 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 following:

                   0 for seeking from beginning
                   1 for seeking from current position
                   2 for seeking from end of file
