Minimal video bandwidth usage

AbhiV · January 18, 2023, 11:26am

Hi

Is there any config which I can set to use minimal bandwidth and still able to see video in jitsi.?
What happening right now is that when a user is using mobile data in jitsi web view, video is some time visible and some time not. Since the mobile data bandwidth is usually low so this issue comes all the time for mobile users.
What I need is, if the bandwidth is low than video quality can decrease but it should be visible all the time.

Try switching codecs to VP9 (assuming the mobile clients that are connecting can decode it).
