GraphViewer 1.0, 1/2006
by Jacob Klint (jklint@juno.com)

DESCRIPTION

GraphViewer is a command-line utility with one simple purpose: it runs a GraphEdit 
filter graph (*.grf).



USAGE

from the command line (cmd.exe):
graphviewer.exe "c:\video\test graph.grf"

Alternatively, you can drag-and-drop the filter graph file (*.grf) onto the 
graphviewer.exe executable.

GraphViewer exits when the graph finishes playing. To stop the graph prematurely, 
kill the "GraphViewer.exe" process in the task manager. 



NOTES

The graph runs just like it does in GraphEdit when you hit "run", so while GraphViewer 
provides no GUI of its own, a video window will open if the filter graph includes 
video playback. However, audio playback or video transcoding without visual feedback 
will run invisibly. 

If you need the GraphEdit executable, it is available here:
http://www.videohelp.com/tools?tool=GraphEdit

This is not necessary for running graphs, but it is useful for creating them.
