input|camera - Unable to select Capture Card

[SquarePixels]

Seems the application can only select USB Cameras / Cature cards. Any way to support capture cards connected via PCI-E or even OBS / Xsplit Virtual Cameras?

I use an Elgato Game Capture HD60 PRO PCI-E card for captures without problems, so USB is not a requirement.

But you're right about it not picking up webcams...

The capture stuff is handled by escapi (here on github at https://github.com/jarikomppa/escapi ). After taking a quick look I see it's using:

	hr = attributes->SetGUID(
		MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE,
		MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE_VIDCAP_GUID
		);
	if (FAILED(hr)) return 0;

	ChooseDeviceParam param = { 0 };
	hr = MFEnumDeviceSources(attributes, &param.mDevices, &param.mCount);

Which looks right according to snippets I've seen. Set a breakpoint and yeah, it's only seeing the capture card and not the other devices. I tested with the latest version of Escapi (from its github) and same results. Not sure.

Edit: I opened an issue over at escapi:

Sorry, I should have been more specific in my issue. UGT seems to only detect the camera built into my Valve Index (Which I guess is the only physical "Webcam" I have connected to my PC.

I also have an Avermedia Live Gamer 4K which was the device I wanted to use but I am unable to select it with input_camera_device_id as it appears only the eTronvideo is selectable.

I think the issue is the same, only full device drivers are recognized with Escapi (which is Media Foundation based), will have to get verification on this though.
