问题
Hello There, I am trying to screen broadcast with latest webrtc libraries but I keep getting following error:
iOS 13.0 & above: Live broadcast has stopped due to Attempted to start invalid broadcast session.
less than iOS13 but greater than iOS 12.0: Live broadcast has stopped due to:(null)
I would really appreciate if anyone can answer my question. Thanks
var peerConnectionFactory: RTCPeerConnectionFactory?
var localVideoSource: RTCVideoSource?
var videoCapturer: RTCVideoCapturer?
func setupVideoCapturer(){
// localVideoSource and videoCapturer will use
localVideoSource = self.peerConnectionFactory!.videoSource()
videoCapturer = RTCVideoCapturer()
localVideoSource.capturer(videoCapturer, didCapture: videoFrame!)
let videoTrack : RTCVideoTrack = self.peerConnectionFactory!.videoTrack(with: localVideoSource, trackId: "100”)
let mediaStream: RTCMediaStream = (self.peerConnectionFactory?.mediaStream(withStreamId: “1"))!
mediaStream.addVideoTrack(videoTrack)
self.newPeerConnection!.add(mediaStream)
}
override func processSampleBuffer(_ sampleBuffer: CMSampleBuffer, with sampleBufferType: RPSampleBufferType) {
switch sampleBufferType {
case RPSampleBufferType.video:
// create the CVPixelBuffer
let pixelBuffer:CVPixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer)!;
// create the RTCVideoFrame
var videoFrame:RTCVideoFrame?;
let timestamp = NSDate().timeIntervalSince1970 * 1000
videoFrame = RTCVideoFrame(pixelBuffer: pixelBuffer, rotation: RTCVideoRotation._0, timeStampNs: Int64(timestamp))
// connect the video frames to the WebRTC
localVideoSource.capturer(videoCapturer, didCapture: videoFrame!)
break
}
}
