onStreamStatus is a method called by the R5Stream on its assigned R5StreamDelegate object. This function allows a developer to gain status information events to monitor the stream.
Begin by publishing to stream1 from a second device. stream1 is the default stream1 name that is used by this example.
While streaming, upon receipt of a flag indication that the current net connection has insufficient bandwidth to properly display the stream, the stream view will appear to darken. If it instead receives a flag saying there is enough bandwidth, the screen will return to normal. To see the effects, the stream should be published in high quality, and the example should be run from a poor network.
onR5StreamStatus is a method of the R5StreamDelegate interface. Any object that impliments this interface can be assigned to the R5Stream.delegate property of an active stream. In this example, SubscriberBandwidthTest is a child ofBaseTest which impliments R5StreamDelegate allowing us to use the object as the delegate for its own stream.
self.subscribeStream!.delegate = selfSubscriberBandwidthTest.swift #29
In order to add functionality, the onR5StreamStatus function from Base Test needs to be overridden. This overridden function can then parse the message sent to it to determine what action, if any, needs to be taken.
override func onR5StreamStatus(stream: R5Stream!, withStatus statusCode: Int32, withMessage msg: String!) {
super.onR5StreamStatus( stream, withStatus: statusCode, withMessage: msg)
if(statusCode == Int32(r5_status_netstatus.rawValue)){
if(msg == "NetStream.Play.SufficientBW"){
//If the message sent to this function indicates Sufficient Bandwidth, make the black overlay comeletely transparent
overlay!.layer.opacity = 0.0
}else if(msg == "NetStream.Play.InSufficientBW"){
//If the message sent to this function indicates Sufficient Bandwidth, make the black overlay half visible, visually dimming the screen.
overlay!.layer.opacity = 0.5
}
}
}
