我正在使用webrtc进行视频聊天。这样,我想在其他参与者加入会议时使用主发言人。为此,我编写了这段代码,但是语音音量很低(意味着声音来自耳机)
func audioSetting() {
RTCAudioSession.sharedInstance().isAudioEnabled = true
let session = AVAudioSession.sharedInstance()
do {
try session.setCategory(AVAudioSession.Category.playAndRecord, mode: .videoChat, options: [])
if self.speakerOn {
try session.overrideOutputAudioPort(.none)
}
else {
try session.overrideOutputAudioPort(.speaker)
}
try session.setActive(true)
self.speakerOn = !self.speakerOn
}
catch let error {
print("Couldn't set audio to speaker: \(error)")
}
}
答案 0 :(得分:0)
我正在使用socket.IO开发webRTC,
func setSpeakerStates(enabled: Bool)
{
let session = AVAudioSession.sharedInstance()
var _: Error?
try? session.setCategory(AVAudioSession.Category.playAndRecord)
try? session.setMode(AVAudioSession.Mode.voiceChat)
if enabled {
try? session.overrideOutputAudioPort(AVAudioSession.PortOverride.speaker)
} else {
try? session.overrideOutputAudioPort(AVAudioSession.PortOverride.none)
}
try? session.setActive(true)
}
在添加音频流和视频流之后,请在 viewdidload 的末尾尝试此方法。
