Hello. Thank you for using my library and sending me a question.
I don't know reason why, but it seems that your camera Logitech brio is not support 'Preview Pin'.
As far as I know, even if camera do not support 'Preview Pin',
DirectShow's component Capture Graph Builder will make 'Preview Pin' automatically
by inserting Smart Tee filter.
This is described in comment line 292 and below. or see also link below.

So, I believed all camera supports 'Preview Pin'.
I do not have any idea to fix this problem at present,
so, as a plan B, is it possible to adopt '2. use Timer and GetBitmap()' approach to show preview?
// 2. use Timer and GetBitmap().
var timer = new System.Windows.Threading.DispatcherTimer();
timer.Interval = TimeSpan.FromMilliseconds(1000.0 / 30);
timer.Tick += (s, ev) => Preview = camera.GetBitmap();
timer.Start();

If you can use GraphEdit, I have some items I would like you to try.
GraphEdit is tool for test DirectShow created by Microsoft.
As to GraphEdit, show page below.
By using GraphEdit, I want you to check Logitech brio has a Preview Pin or not.

Thanks for quick response!
If i try with the second, timer option, i get this:
I have managed to setup GrapEdit and i inserted my device in it as shown in screenshot below. What do you want me to try?

By using timer, you got black image, right?
Something is wrong...
Does another app can use Logitech BRIO? for instance, windows camera app can use the camera?
thank you for sending screen shot.
there are 2 Capture Pin. does the camera has 2 dual cameras like in camera and out camera? I have never tested dual camera. It can be the reason.
