NAME

       oggCut - extracts parts of an ogg file (.ogv, .ogg and .oga)

SYNOPSIS

       oggCut [options] inputfile outputfile

DESCRIPTION

       oggCut creates a new ogg file named outputfile as a subpart of the original file named inputfile

       oggCut is able to cut video (theora) only files, audio (vorbis) only files or files with both video and audio streams.

       The start and end time for the cut area must be given in milliseconds with the options -s and -e.

       As  a video stream consists of I-frames (which are full pictures) and P-frames (which are delta pictures to the leading I-frame) the oggCut
       algorithm searches for the first I-frame. If a video file would start with a p-frame, the player is not able to interpret this picture,	as
       the leading I-frame (on where it is based) is not available.  oggCut starts the I-frame search at the start time given by the -s option. So
       expect a shorter video time than the calculated seconds for the new file.

       oggCut does not do any reencoding, therefore the output quality is completely the same as from the input file.

       For those involved into the ogg container format: The file is cut on packet basis, not on page basis.

       There is another tool called oggCut out in the internet with a different synopis. This one has not been written by the author of this  tool
       you are actually using.

OPTIONS

       -s     Cut start position in ms. If the input file is a video file, the cut area starts with the next keyframe found. Default: 0

	      Example: -s 5000

       -l     Length of the cut area in ms. If -e is also given, the length is ignored.

	      Example: -l 10000

       -e     Cut end position in ms. If -l is also used, the end position is prefered. If the end position is set to -1, the end of the stream is
	      assumed.

	      Default: -1

	      Example: -e 20000

EXAMPLE

       oggCut -s 1000 -e 21000 myVideo.ogv myOutput.ogv

       Creates a new video called myOutput.ogv from the video myVideo.ogv starting after 1 second ending after 21 seconds

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
