过滤实时相机送纸 [英] Filter Live camera feed

问题描述

所以我一直在使用UIImagepickercontroller访问相机进行照片和视频捕捉，然后我想在这两个来源上应用过滤器，我成功地过滤了令牌照片，但我找不到其余的解决方案，我只需要访问原始图像数据：相机显示的实时图像输入，应用过滤器，然后显示过滤的图像。任何帮助或建议将不胜感激。

So i've been using UIImagepickercontroller to access the camera for photo and video capture, then i wanted to apply filters on those 2 sources, i succeeded with filtering token photos but i'am having trouble finding the solution for the rest, all i need is to access the raw image data : the live image feed that the camera is showing , apply the filter and then show the filtered ones instead. Any help or advice will be appreciated.

推荐答案

UIImagePickerController不会为您提供对相机缓冲区的低级访问。

UIImagePickerController doesn't give you low level access to the camera buffer.

你应该设置一个AVCaptureSession并使用委托来处理CMSampleBufferRef

You should setup a AVCaptureSession and use the delegate to process the CMSampleBufferRef

看看AVCam&来自Apple的SquareCam演示，他们对视频捕捉进行了很好的介绍。

Take a look at the AVCam & SquareCam demos from Apple, they give a good introduction to video capture.
