抱歉我没注意。请参阅编辑后的答案，也许您会觉得它很有用。

- (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection {
        CVPixelBufferRef pixelBuffer = (CVPixelBufferRef) CMSampleBufferGetImageBuffer(sampleBuffer);
        CIImage *image = [CIImage imageWithCVPixelBuffer:pixelBuffer];
        [_coreImageContext drawImage:image inRect:[image extent] fromRect:[image extent]];
        [_context presentRenderbuffer:GL_RENDERBUFFER ];
    }
