tkMovie

			alpha version, March, 1995 (c)
			     tkMovie-0.01A.tar.gz

tkMovie is an extention to tk which provides a movie widget to display
and manipulate mpeg video streams in tk by providing a new tk command movie.

The movie widget has the following commands ;-

play :	The play command takes an optional argument to specify how many
	frames of the mpeg to play. If specified with no options this
	command will play one frame. If the number specifed is greater
	than the number of frames available and the loop option is not
	set the mpeg will play to the end leaving the last frame on display
	otherwise wrap round will occur.
	example .mymovie play		# plays 1 frame
		.mymovie play 25	# plays 25 frames 

rewind : This will rewind the mpeg to the start and display the first frame.


framenumber : This will return the current framenumber.

The movie widget takes the following configure options ;-


-file	:	This is used to specify the mpeg file to read.
		This is NEEDED when you use the movie command (at the mo)

-dither :	This can set the dither that will be used when displaying
		the mpeg. This defaults to ordered2. The dither can be
		specified at startup or at any other time. valid dithers are
		ordered
		ordered2
		mbordered
		fs4
		fs2
		fs2fast
		hybrid
		hybrid2
		2x2
		gray
		color
		none
		mono
		threshold.
		(Note. threshold, color, none, mono. dont work properly
		 yet. also if you change the dither while running you
		 leak a bit of the memory. It is an alpha !)

-loop	:	This takes any boolean value as as its parameter to
		specify what should happen when the movie gets to the last
		frame. It defaults to false so that the movie stops leaving 
		the last available frame displayed.
		If set to true wrap round occurs.

 
-relief, -bd etc and must standard tk configure options.

tkMovie is based on the excellent mpeg_play produced at berkeley by
Lawrence Rowe , Ketan Patel and Brain Smith. It also uses a much modified
version of mpeg_lib by Greg Ward (greg@pet.mni.mcgill.ca) though not much is
left of this. These code fragments have their own copyrights included with 
the source. Sorry to Greg and berkeley crew for making such a mess of their
code.
