Description

I am using a usb video camera with a button and I would like to take a picture when the user clicks the button. I have asked the camera manufacture about it and they said it is part of the UVC protocol. The button works out of the box using AMCap software, but I can't find much information online about it. How do I detect the button click using JavaCV?

Contributor guide

Research direction
Investigate how UVC buttons are exposed via FFmpeg or DirectShow, and look for JavaCV/FFmpeg bindings for UVC extension units.
