Jitsi SDK Customisation

Hi,

I have some questions regarding Jitsi video conferencing SDK (iOS).

  1. I want to show only my video (only one participant) in the group video call, can we customize the video view like this in Jitsi Video SDK?
  2. Can we Mute/Unmute audio.
  3. Can Hide/Show Video.
  4. I want to record the individual participant video from the group call.
    is it possible in Jitsi Video SDK?

Thanks in advance.
