我想用AVSampleBufferDisplayLayer显示一些CMSampleBuffer，但它在显示第一个示例后卡住。我从AVCaptureVideoDataOutputSampleBuffer委托(delegate)中获取样本缓冲区:-(void)captureOutput:(AVCaptureOutput*)captureOutputdidOutputSampleBuffer:(CMSampleBufferRef)sampleBufferfromConnection:(AVCaptureConnection*)connection{CFRetain(sampleBuffer)

我想分享我这几天积累的知识。没有太多关于它的信息。我还在为声音嘶嘶作响。欢迎提出意见和提示。;-) 最佳答案 这是我的代码片段。声明一下@property(nonatomic,retain)AVSampleBufferDisplayLayer*videoLayer;首先设置视频层self.videoLayer=[[AVSampleBufferDisplayLayeralloc]init];self.videoLayer.bounds=self.bounds;self.videoLayer.position=CGPointMake(C
