启用UIImagePickerController视频压缩

Question

Is there a way to enable video compression on video files recorded with UIImagePickerController?

When videos are selected from cameraroll with UIImagePickerController they are automatically compressed.

Are there any other way of compress a video? I've got access to the file with a NSURL.

Answer 1

I'm not aware of a way to change the compression as it's being recorded.

You can set the videoQuality property of the UIImagePickerController to get a copy at a different bitrate.

For example "High" is: UIImagePickerControllerQualityTypeHigh = 0
