Similarly, video bitrate on start can be set (x-google-start-bitrate attribute) and maximum bitrate can be limited (x-google-max-bitrate attribute)Note that this . Note that if minimum bitrate only is set, then resulting bitrate cannot be above 2500 kbps, probably maximum bitrate value is fixed on this level by default in Chrome browser. When higher bitrate values are required, for example, to publish high reso;ution streams, both minimum and maximum values must be explicitly set:

a=fmtp:$1 $2;x-google-max-bitrate=7000;x-google-min-bitrate=3000

In this case browser will try to keep bitrate in limits from 3000 to 7000 kbps when publishing a stream.

This feature is available in Chrome browser only.

Setting up codecs

When publishing the stream, there is a possibility to eliminate from WebRTC SDP codecs that should not be used to publish the given stream, for example:

    publishStream = session.createStream({
        ...
        stripCodecs: ["h264", "flv", "mpv"]
    }).on(STREAM_STATUS.PUBLISHING, function (publishStream) {
        ...
    });
    publishStream.publish();
