Usage of Jitsi Video Call and Camera

[ErsinDemirbas]

In my android application, I use Jitsi meet video call in the first activity and natario cameraview in the second. The aim is to switch to the other activity with a button and read the user's ID card while the video call is taking place. But jitsi doesn't share camera resource with cameraview object, so I see black screen on natario cameraview side. I wish Jitsi side had a black screen because I'm doing ID reading in activity 2 and the camera is a must. So is there a way to get the camera from jitsi? Maybe with camera sessions.?
