Connection fails On Android #558

Open ohohooops opened 6 years ago

ohohooops commented 6 years ago

I have already installed RTCMultiConnection from : https://github.com/muaz-khan/RTCMultiConnection

It works on PC IOS and some Android systems but while Android connects with laptop for joining video chat, laptop's user can't see video.

The laptop log message shows : remote peer sdp ... a = recvonly.

is there anything Android setting I can do to changing from 'recvonly' to 'sendrecv', Thank so much.

Remote peer's sdp:

Due my tests the problem is related to android versions. New Android versions prevent accessing to mic or camera, but old versions (4.4 for example) are fine. Hope this helps
