Hi all,

I need an example of usage of the DeviceType = rvdtUserData, so for instance,

• compose a PIP from two network cameras,
• or a side-by-side from two cameras,
• or add a text overlay on the original image from a single camera.

Any help will be very appreciate.

Thanks in advance

The example of this mode is in ClientServer\VideoChats\Lecture\Lecturer. It is used to display slides.

As for drawing additional information on video frames, you can also use TRVCamera.OnGetImage (but be careful, this event is called in a thread context).
For drawing addition information on displaying, you can use TRVCamView.OnPaint (see the demos Cameras\Filter, MotionDetect and MotionDetect_Old)

Thanks for the information. This sounds great.

I'm going to develop a small prototype based on the example programs you suggested.

Regards,
