Video is m line 1. It appears sdpMLine index is 0 in every ice candidate generated, so I guess they are not being computed correctly. Chrome and Safari seem to tolerate this error, but Firefox throws an exception saying it is invalid for this reason. Steps to Reproduce: 1. Go to https://output.jsbin.com/cupuvaw 2. Allow devices access 3. Open console Expected Results: sdpMLineIndex of ice candidates should match the m line indexes of the sdp, generally 0 for audio, 1 for video. Actual Results: sdpMLineIndex is 0 for all ice candidates, both video and audio, which is not consistent with the sdp.
