How to enable h264 in webrtc?

These are my mediaConstraints

var mediaConstraints = {
    video: {
        mandatory: {
           maxWidth: 640,
           maxHeight: 480
        }
    },
    audio: true
};

Answer 1

It would seem that H264 is not supported by default. You will need to add the codec string manually to SDP before setting it as local and submitting the offer. They seem to be working very hard to figure this out. You can see this with the work that jesup does in his meetings on April 22 and April 29
