RTCPeerConnection.getStreamById()
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
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
.
Warning: 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;
