Facility Control

Hi all, 

I am building a dashboard and looking for a way to display time remaining on a clip playing off of expressions clips server on an expression dashboard. Any help will be greatly appreciated.

Thank You!

Hi Kemal,

Thanks for your query.

Here is what I found for you!.

I have attached an example DashBoard Custom Panel, that can display Clip ID  and Time remaining once you connect to VDCP client successfully.

Basic Set-ups that need to be there before you run this panel

1. Start Xpression media control gateway(clip server to feed) in order to run clips 
2.  Configure and VDCP port number and start it
3.  Make sure Clip Store has been set up 
4. Start clip server chanel on xpression
5. Open clip browser to view clips
6.  Now open up the example panel on the DashBoard
7.  Enter the Host number. If you are running it locally then you can add as localhost
8.  Enter the port number
9.  Enter the valid clip name that currently exists in the clip browser
10.  Hit button cue and play
11.  It should display the time remaining which will matches time remaining for clip running on XPression .

Example Panel Code (You can paste this into note pad and name it as .grid and then open it through DashBoard)

Note: I have also highlighted the code snippet in Bold that you may interested.

Panel Code:
