I found a post from about a year ago from someone looking to do something similar. They had asked about the Sony.MediaSoftware.ExternalVideoDevice namespace
That sounds like it would be useful. Is there any information any where about it? It sounds like its not really supported or documented, but would be useful.

Using the object browser, I've uncovered the class VegasCapturePanel and the class CaptureDockWnd.
I feel like this is totally doable, but I need some help getting it going.
I tried something like this, but I'm not sure how to get it to actually pop up the control and then be able to manipulate it.

CaptureDockWnd dck = new CaptureDockWnd();
VegasCapturePanel vCp = new VegasCapturePanel(vegas, dck);

I've got the interface to show up using the following:

CaptureDockWnd dck = new CaptureDockWnd(); ;
dck.DisplayName = "Test";
dck.PersistDockWindowState = true;
vegas.LoadDockView(dck);

Now I just have to figure out how to access the CapturePanel that gets built and its capsettings.captureclip property.

Making some progress. I'm able to access the docked control and do a few things, but I can't seem to get the capture to happen:

Sony.Vegas.IDockView testI = null;
if (vegas.FindDockView("NewCap", out testI))
{
dck = (CaptureDockWnd)testI;
vegasCapPanel = (VegasCapturePanel)dck.Controls[0];
vegasCapPanel.SetProjectCaptureDir(@"c:\temp");

vegasCapPanel.StartCapture(null, null);

System.Threading.Thread.Sleep(5000);

// vegasCapPanel.StopCapture(null, StopCaptureFlags);


If anyone out there from Sony could hook me up with a wee bit of help, that'd be great. I understand this isn't supported, but now I'm sure it is possible.

Got it. Here's the info in the unlikely case anyone else ever needs to do this...

I'm defining some variables in my main control so I can access them later:
private VegasCapturePanel vegasCapPanel;
private CaptureDockWnd dck;

Then in my function to do the capturing:

Sony.Vegas.IDockView testI = null;
if (vegas.FindDockView("NewCap", out testI))
{
dck = (CaptureDockWnd)testI;
vegasCapPanel = (VegasCapturePanel)dck.Controls[0];
vegasCapPanel.Controller.StartCapture(@"C:\temp\test", "Test", "Tape1", "Comment", "E", null, null);
if (vegasCapPanel.Controller.IsCapturing)
{
System.Threading.Thread.Sleep(5000);
StopCaptureFlags testFlags = new StopCaptureFlags();
vegasCapPanel.Controller.StopCapture(testFlags);
vegasCapPanel.Controller.Load();
MessageBox.Show("captured");
}
else
{
MessageBox.Show("Error Starting Capture");
}

//}
}
else
{
MessageBox.Show("Please Open a Capture Window");
}

Hi Jason,
I am not able to run your code.
I started my code with the following:

CaptureDockWnd dck=new CaptureDockWnd();

VP8 throws an exception at the line. Can you please post your entire code

Thanks

Maybe you need to add references to the dll files to your project. I referenced the following in my project:

C:\Program Files\Sony\Vegas Pro 9.0\Sony.Capture.dll
C:\Program Files\Sony\Vegas Pro 9.0\Sony.MediaSoftware.ExternalVideoDevice.dll


Does that help at all? I'm afraid I can't post my full code, because my full program is doing a lot more than just the capture part.
