Why the muted video tag cannot be unmuted?
Dear All
I am building a Web application using WebRTC technology.
The problem is that I cannot unmute the muted media which has the muted attribute.
This is my video tag that receive the remote media stream:
<video id="remoteView" width="320" height="240" autoplay controls muted></video>
The following coding for add local media stream to the remote RTCPeerConnection object.
setupStream=((stream)=>{
if (pc){
var senders=pc.getSenders();
if (senders.length<1) {
stream.getTracks().forEach((track)=>{
logger("0 add "+track.kind+" track");
pc.addTrack(track,stream);
});
} else {
senders.forEach((sender)=>{
if (sender.track)
sender.track.stop();
});
stream.getTracks().forEach((track)=>{
var sender = pc.getSenders().find(function(s) {
if (s.track)
return s.track.kind == track.kind;
else
return null;
});
if (sender==null) {
logger("1 add "+track.kind+" track");
pc.addTrack(track,stream);
} else {
logger("0 replace "+track.kind+" track");
sender.replaceTrack(track);
}
});
}
}
The following code handle ontrack event:
remoteVideo=document.getElementById("remoteView");
if (remoteVideo.srcObject==null){
remoteView.srcObject=event.streams[0];
} else {
remoteVideo.srcObject.addTrack(event.track);
}
The problem is that when I add 1 audio track to remote RTCPeerConnection object first, and then add 1 video track to remote RTCPeerConnection object, the remote side default control panel unmute button working properly.
However, if I add 1 video track to remote RTCPeerConnection object first, and then add 1 audio track to remote RTCPeerConnection object, the remote side default control panel unmute button does not work. I need to right-click the media player and then select "unmute" to play remote audio.
I am using FireFox version 77.0.1 Chinese edition. I am using windows 10 OS.
Would you tell me what is going on?
