如何从CVImageBuffer对象获取原始数据 [英] How can I obtain raw data from a CVImageBuffer object

问题描述

我尝试使用可可从网络摄像头抓取图像。我可以使用QTKit和didOutputVideoFrame代理调用获得RGBA格式的图像，并将CVImageBuffer转换为CIImage，然后转换为NSBitmapImageRep。

I'm trying to use cocoa to grab images from a webcam. I'm able to get the image in RGBA format using the QTKit and the didOutputVideoFrame delegate call, and converting the CVImageBuffer to a CIImage and then to a NSBitmapImageRep.

我的相机在YUV本地抓取，我想要的是直接从CVImageBuffer获取YUV数据，并在显示之前处理YUV帧。

I know my camera grabs natively in YUV, what I want is to get the YUV data directly from the CVImageBuffer, and proccess the YUV frame before displaying it.

我的问题是：如何从CVImageBuffer获取YUV数据？

My question is: How can I get the YUV data from the CVImageBuffer?
