[kepler-dev] Displaying a video from hard disk.

Hi Anjani,
    Attached is a very simple workflow with an example. This example is 
called commandLine.xml and it has a SDF directoror plus a single actor, 
a 'CommandLineExec' actor. It is OS-specific in that it was set up for 
Windows. If you double click on the CommandLineExec actor you will see 
that the command is "/AAAA/edit0001.avi". (Note that the avi file is not 
attached due to its size.) If you execute this workflow, it should use 
the Windows Media Player to display the avi on the command line! (see 
comment below).
    Note that anything that runs from the command line on your platform 
should be executable with the CommandLineExec actor. You may have to 
include the application name (e.g Quicktime or Windows Media Player) 
followed by the file to display. Check the documentation for the ports 
and parameters.
    Of course this approach is OS specific. Details would be different 
for Windows, Macs, and Linux boxes.

PS - I just noticed that running the sample on my Windows machine only 
works IF I have previously displayed the avi file by double clicking on 
it in the Windows Explorer (which launches the Windows Media Player) You 
may have to play around with the command line expression.
