I was hoping someone in TANDBERG land can help me with this...
I have a couple of questions about compositing video sources.

From the c90 value space, I can see VideoSourceType has several
sources types…

<VideoSourceType item="1" type="Literal">
<Value item="1">graphic</Value>
<Value item="2">localInput</Value>
<Value item="3">localMain</Value>
<Value item="4">localPresentation</Value>
<Value item="5">mostSpeaking</Value>
<Value item="6">otherMain</Value>
<Value item="7">ownMain</Value>
<Value item="8">presentation</Value>
<Value item="9">remoteMain</Value>
<Value item="10">remotePresentation</Value>
<Value item="11">videoFile</Value>
</VideoSourceType>

Why is “presentation” separate from “localPresentation” and “remotePresentation”?
How do “graphic “ and “videoFile” work? Is this a reference to a file on the codec?
The layout add frame command is below…

     <Add item="1" command="True">
        <LayoutId item="1" required="True" valueSpaceRef="/Valuespace/LayoutId[@item='1']"/>
        <FrameId item="1" required="False" valueSpaceRef="/Valuespace/FrameId[@item='1']"/>
        <PositionX item="1" required="True" valueSpaceRef="/Valuespace/WindowOffsetXRange[@item='1']"/>
        <PositionY item="1" required="True" valueSpaceRef="/Valuespace/WindowOffsetYRange[@item='1']"/>
        <Width item="1" required="True" valueSpaceRef="/Valuespace/WindowSizeXRange[@item='1']"/>
        <Height item="1" required="True" valueSpaceRef="/Valuespace/WindowSizeYRange[@item='1']"/>
        <Layer item="1" required="True" valueSpaceRef="/Valuespace/WindowLayer[@item='1']"/>
        <Border item="1" required="False" valueSpaceRef="/Valuespace/OnOff[@item='1']"/>
        <VideoSourceType item="1" required="True" valueSpaceRef="/Valuespace/VideoSourceType[@item='1']"/>
        <VideoSourceId item="1" required="False" valueSpaceRef="/Valuespace/VideoSourceId[@item='1']"/>
      </Add>

It does not seem to allow me to specify a system file path.

Thanks in advance,
Anthony

Hi Anthony and sorry for the late answer,

Why is “presentation” separate from “localPresentation” and “remotePresentation”?

presentation is the currently active presentation (local or remote)
localPresentation is the locally configured presentation source
remotePresentation is the presentation of a remote participant (callId required)

The graphic and videoFile VideoSourceTypes are currently not possible to use.

Regards,
Viggo

Are you planning on using the graphic and videoFile VideoSourceTypes in the future? I would like to display a 'watermark' of our University logo on the lower right hand side of the screen. Is there currently a way to do this?

Thanks.
