Hello,

I try to get a snapshot of the preview to see what's cued. Using the snapshot methode in the SDK I only receive the program output. Can you give me a clue?


Thanks!

On the Cluster Class you have a Snapshot method that takes the Pipe IID as a parameter. This should help you.

Unfortunately not realy. If I'm using 0 for PipeIID, I get the program output - that's fine. But if I'm using 1 for preview, I only get the black screen (with Ventuz watermarking in PLE) even if I see a cued scene in Director. So what I'm doing wrong?

Thank,
Meldur

Hi Meldur,

currently you seem to render the program pipe only. This is because you have only defined one pipe in your Audio Video Configuration on the output machine.

In order to take a snapshot, the scene needs to be rendered - for this you need to create a second pipe in the AV Configuration on your remoted machine. Best use an off-screen pipe for this.

If your first pipe is a DVI output, though, this is not possible unfortunately. You need to have an SDI or NDI output to be able to create a second output pipe.

A better practice than letting the output machine render a preview might be to let your remoting machine (i.e. the local machine) render the preview. Here you can define two off-screen pipes in the AV configuration and then take snapshots on both of them. For this you can create a second Cluster object that is connected to the localhost. Btw. this is exactly what the Ventuz Director does - on the Director Machine in the background a Ventuz Runtime is running with two off-screen pipes each rendering the program or preview - the Director grabs the rendertargets of the GPU and renders them on the UI.

Hope this gives you enough hints for a viable solution.
