AVCaptureSession，AVCaptureAudioData输出和背景音乐 [英] AVCaptureSession, AVCaptureAudioDataOutput and background Music

问题描述

我使用AVCaptureVideoDataOutput和AVCaptureAudioDataOutput用AVFoundation录制音频/视频.但是，当我将AVCaptureAudioDataOutput添加到AVCaptureSession时，AVFoundation停止背景音乐(以iPod app为例).

I record audio/video with AVFoundation using AVCaptureVideoDataOutput and AVCaptureAudioDataOutput. But when I add my AVCaptureAudioDataOutput to my AVCaptureSession, AVFoundation stop background music (in my case from iPod app).

所以我正在寻找一种解决方案，以便在录制过程中播放音乐?

So I'm looking for a solution to let my music playing during my record ?

谢谢

阿拉

ps:我的目标是iOS8，使用的是Swift 2.0

推荐答案

    do {
      try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord, withOptions: [AVAudioSessionCategoryOptions.MixWithOthers, AVAudioSessionCategoryOptions.DefaultToSpeaker])
      try AVAudioSession.sharedInstance().setActive(true)

    } catch {
      print("error")
    }

    captureSession = AVCaptureSession()
