MediaTrackConstraints: echoCancellation property
The MediaTrackConstraints dictionary's
echoCancellation property is a
ConstrainBoolean describing the requested or mandatory constraints placed
upon the value of the echoCancellation constrainable property.
If needed, you can determine whether or not this constraint is supported by checking
the value of MediaTrackSupportedConstraints.echoCancellation as returned
by a call to MediaDevices.getSupportedConstraints(). However, typically
this is unnecessary since browsers will ignore any constraints they're unfamiliar with.
Because RTP doesn't include this information, tracks associated with a
WebRTC RTCPeerConnection
will never include this property.
Value
If this value is a simple true or false, the user agent will
attempt to obtain media with echo cancellation enabled or disabled as specified, if
possible, but will not fail if this can't be done. If, instead, the value is given as an
object with an exact field, that field's Boolean value indicates a required
setting for the echo cancellation feature; if it can't be met, then the request will
result in an error.
Examples
See the Constraint exerciser example.
