Check the Browser compatibility table carefully before using this in production.
Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The RTCPeerConnection.getStreamById()
method returns the
MediaStream
with the given id that is associated with local or remote end of the connection. If no
stream matches, it returns null
.
This property has been replaced with the
RTCPeerConnection.getLocalStreams
and
RTCPeerConnection.getRemoteStreams
properties. If you have code that
uses stream
, you will need to update, since browsers have begun to remove
support for stream
.
Syntax
var mediaStream = pc.getStream(id);
Parameters
- id
- Is a
DOMString
corresponding to the stream to return.
Example
var stream = pc.getStreamById(myTrackId);
if (stream) {
console.log("Found stream: " + stream.id);
}
Polyfill
Running the following code before any other code will create
RTCPeerConnection.prototype.getStreamById()
if it's not natively available.
// from: https://bugs.chromium.org/p/chromium/issues/detail?id=698163&desc=5#c10
RTCPeerConnection.prototype.getStreamById = function(id) {
try {
var localStreams = this.getLocalStreams();
var remoteStreams = this.getRemoteStreams();
var i;
for (i = 0; i < localStreams.length; i++) {
if (localStreams[i].id == id)
return localStreams[i];
}
for (i = 0; i < remoteStreams.length; i++) {
if (remoteStreams[i].id == id)
return remoteStreams[i];
}
} catch(e) {}
return null;
}
