VPCScreen is a video producer service for the AccessGrid that captures your desktop (or part thereof) and sends it as an H261, H261AS or JPEG video stream.
It is particularly useful for when you wish to send only part of a display, or just a single window.
VPCScreen is available for Linux, MacOS, and Windows.

VPCScreen Capture should now be installed
To use VPCScreenCapture, the service must be added to your Venue Client configuration.
In Tools->Configure node services..., select the Service Manager, select AddService, select the VPCScreenProducerService, and OK. VPCScreenCapture will start. At this point you have three options:
With this option, your entire screen will be streamed when you press Start.
With this option, you will be prompted to drag out a region of the screen; when finished, that region will be streamed when you press Start.
With this option, you will be prompted to select a window; when finished, that window will be streamed when you press Start.
If you want to switch between these modes while VPCScreen is running, you must Stop and Start.
Streaming of a PowerPoint or equivalent presentation
Streaming a video/animation
Streaming a unique application
Streaming any particular item from your desktop to everyone else
All is required is the latest version of vic, which come supplied with the AGTK 3.1Beta2 (or later) release
Because video stream is injected into the multicast stream, you can record (using AGVCR or similar) presentations as part of the recording.
