Jitsi api control on android

Hello all ,

I have successfully set up the jitsi custom server and using jitsi SDK version 2.8.2 I am able to do a conference call.

My purpose in using jitsi is for doing live streaming.
Currently whenever from android side i join the link it call another fragment which is followed by jitsi it shows controlling of camera view and audio mute or on.

I want to implemented such that i can control camera switching and volume control.
currently it shows control in jitsi activity after which i cannot not control audio and camera switch without user input.
So i want to do it programmatically with no user input

can anyone has idea how to do this ?
