How to configure the default audio (eg. PCMA OPUS) and video (VP8 or H264) codec for webrtc video calls and the sending frequency (5s or 10s or 60s) of IDR key frames in video streams

InnovateAsterisk commented 2 years ago

Codec details and selection should be done on the Asterisk side allow=!all,opus,VP8 also for ptime: allow=!all,opus:20,VP8

You can also apply the Media Track Constraints here: https://developer.mozilla.org/en-US/docs/Web/API/MediaTrackConstraints

At the time of capturing the device - there are no settable options at the moment, except sampleRate is applied to video channels. It's set as exact.
