很抱歉,如果这是重复的,但我找不到类似的问题。我有一个我用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音频从其他应用程序运行,因为它现在停止音频(甚至不会暂停它),然后记录视频

如果我正确思考,可以通过添加类似的内容来解决这个问题:

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

示例代码:

AVAudioSession *session = [AVAudioSession sharedInstance];
session.delegate = self;

NSError *error = nil;
[session setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];

OSStatus propertySetError = 0;

UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
propertySetError = AudioSessionSetProperty ( 
    kAudioSessionProperty_OverrideAudioRoute,                         
    sizeof (audioRouteOverride),                                      
    &audioRouteOverride                                               
); 
[session setActive:YES error:&error];

This fixed it.


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