先决条件

确保您已经设置并激活了您的AVAudioSession。

import AVFoundation

do {
   try AVAudioSession.sharedInstance().setPreferredSampleRate(44_100)
   try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord)
   try AVAudioSession.sharedInstance().setMode(AVAudioSessionModeDefault)
   try AVAudioSession.sharedInstance().setActive(true)
   } catch {
}

RTMP使用

实时消息协议（RTMP）。

var rtmpConnection:RTMPConnection = RTMPConnection()
var rtmpStream:RTMPStream = RTMPStream(connection: rtmpConnection)
rtmpStream.attachAudio(AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeAudio)) { error in
    // print(error)
}
rtmpStream.attachCamera(DeviceUtil.device(withPosition: .back)) { error in
    // print(error)
}

var lfView:LFView = LFView(frame: view.bounds)
lfView.videoGravity = AVLayerVideoGravityResizeAspectFill
lfView.attachStream(rtmpStream)

// add ViewController#view
view.addSubview(lfView)

rtmpConnection.connect("rtmp:///appName/instanceName")
rtmpStream.publish("streamName")
// if you want to record a stream.
// rtmpStream.publish("streamName", type: .localRecord)

设置

let sampleRate:Double = 44_100

// see: #58
#if(iOS)
do {
    try AVAudioSession.sharedInstance().setPreferredSampleRate(sampleRate)
    try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord)
    try AVAudioSession.sharedInstance().setMode(AVAudioSessionModeDefault)
    try AVAudioSession.sharedInstance().setActive(true)
} catch {
}
#endif

var rtmpStream:RTMPStream = RTMPStream(connection: rtmpConnection)

rtmpStream.captureSettings = [
    "fps": 30, // FPS
    "sessionPreset": AVCaptureSessionPresetMedium, // input video width/height
    "continuousAutofocus": false, // use camera autofocus mode
    "continuousExposure": false, //  use camera exposure mode
]
rtmpStream.audioSettings = [
    "muted": false, // mute audio
    "bitrate": 32 * 1024,
    "sampleRate": sampleRate, 
]
rtmpStream.videoSettings = [
    "width": 640, // video output width
    "height": 360, // video output height
    "bitrate": 160 * 1024, // video output bitrate
    // "dataRateLimits": [160 * 1024 / 8, 1], optional kVTCompressionPropertyKey_DataRateLimits property
    "profileLevel": kVTProfileLevel_H264_Baseline_3_1, // H264 Profile require "import VideoToolbox"
    "maxKeyFrameIntervalDuration": 2, // key frame / sec
]
// "0" means the same of input
rtmpStream.recorderSettings = [
    AVMediaTypeAudio: [
        AVFormatIDKey: Int(kAudioFormatMPEG4AAC),
        AVSampleRateKey: 0,
        AVNumberOfChannelsKey: 0,
        // AVEncoderBitRateKey: 128000,
    ],
    AVMediaTypeVideo: [
        AVVideoCodecKey: AVVideoCodecH264,
        AVVideoHeightKey: 0,
        AVVideoWidthKey: 0,
        /*
        AVVideoCompressionPropertiesKey: [
            AVVideoMaxKeyFrameIntervalDurationKey: 2,
            AVVideoProfileLevelKey: AVVideoProfileLevelH264Baseline30,
            AVVideoAverageBitRateKey: 512000
        ]
        */
    ],
]

// 2nd arguemnt set false
rtmpStream.attachAudio(AVCaptureDevice.defaultDeviceWithMediaType(AVMediaTypeAudio), automaticallyConfiguresApplicationAudioSession: false)

身份验证

var rtmpConnection:RTMPConnection = RTMPConnection()
rtmpConnection.connect("rtmp://username:password@localhost/appName/instanceName")

屏幕截图

// iOS
rtmpStream.attachScreen(ScreenCaptureSession(shared: UIApplication.shared))
// macOS
rtmpStream.attachScreen(AVCaptureScreenInput(displayID: CGMainDisplayID()))

HTTP使用

HTTP实时流（HLS）。您的iPhone/Mac变成IP相机。基本片段。您可以看到http://ip.address:8080/hello/playlist.m3u8

var httpStream:HTTPStream = HTTPStream()
httpStream.attachCamera(DeviceUtil.device(withPosition: .back))
httpStream.attachAudio(AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeAudio))
httpStream.publish("hello")

var lfView:LFView = LFView(frame: view.bounds)
lfView.attachStream(httpStream)

var httpService:HLSService = HLSService(domain: "", type: "_http._tcp", name: "lf", port: 8080)
httpService.startRunning()
httpService.addHTTPStream(httpStream)

// add ViewController#view
view.addSubview(lfView)
