如何在后台录制视频并保持音乐播放? [英] How to record video and maintain music playing in the background?

问题描述

很抱歉，如果这是重复的，但是我找不到类似的问题.我有一个使用AVFoundation制作的自定义摄像机/录像机，我想知道如何在录制视频的同时保持其他应用程序的音频运行，因为现在它会停止音频(甚至不暂停它)，然后录制视频

Sorry if this is a duplicate, but I couldn't find a question similar to this. I have a custom camera/recorder that I made with AVFoundation and I was wondering how to keep the audio running from other apps while recording a video because right now it stops the audio (doesn't even pause it) and then records the video

如果我的想法正确，是否可以通过添加类似于以下内容的方法来解决此问题:

If I am thinking correctly, could this be solved by adding something similar to this:

 [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];

推荐答案

This fixed it.


[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord
                                 withOptions:AVAudioSessionCategoryOptionDefaultToSpeaker | AVAudioSessionCategoryOptionMixWithOthers
                                       error:nil];
