我可以使用 AVFoundation 在 iPhone 3G 上录制视频吗？

Question

Is it possible to record video on iphone 3g with ios 4.1 using AVFoundation? I m able to record audio and can pick still image using AVFoundation but not able to record video.

Answer 1

If you see the AVFoundation reference documentation its stated that

You should typically use the highest-level abstraction available that allows you to perform the tasks you want. For example:

• If you simply want to play movies, you can use the Media Player
  Framework (MPMoviePlayerController or MPMoviePlayerViewController), or for
  web-based media you could use a
  UIWebView object.
• To record video when you need only minimal control over format, use the
  UIKit framework
  (UIImagePickerController).

Answer 2

As long as a device has a camera, you should be able to record using AVFoundation, check out the AVCam demo code from WWDC 2010 to see how you can do that.
