接入指南 | 两步实现视频直播

/// 在viewDidLoad里一般会这样设置- (void)viewDidLoad {    [super viewDidLoad];    /// 视频直播准备    [RCLiveVideoEngine.shared prepare];    /// 添加视频预览    UIView *previewView = [RCLiveVideoEngine.shared previewView];    previewView.frame = self.view.bounds;    [self.view addSubview:previewView];}
/// 视频流输出回调- (CMSampleBufferRef)didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer {    // 美颜    return sampleBuffer;}

/// 准备完成，点击开启- (IBAction)begin {    /// 调用服务器创建房间接口    [network createRoom:^(NSString *roomId) {        /// 开启直播，需要传入roomId，roomId为业务服务器返回        [RCLiveVideoEngine.shared begin:roomId completion:^(RCLiveVideoErrorCode code) {            if (code == RCLiveVideoSuccess) {                /// success            } else {                /// failure            }        }];    }];}

- (void)setupMixType:(RCLiveVideoMixType)type {    [RCLiveVideoEngine.shared setMixType:type completion:^(RCLiveVideoErrorCode code) {        /// TODO code    }];}
- (void)roomMixTypeDidChange:(RCLiveVideoMixType)mixType {    /// TODO setup UI}
