有没有办法在通过 peerConnection() 将本地视频流“localStream”发送到另一个对等点之前对其进行编辑?
navigator.getUserMedia({video: true, audio: true}, function(localMediaStream) {
var video = document.querySelector('video');
//How do I say edit a few pixes in the localMediaSttream before
//using peerConnection() to send it to another peer?
}, onFailSoHard);
