I am choosing videos using UIImagePickerController, then uploading the video to a web server

  • 0

I am choosing videos using UIImagePickerController, then uploading the video to a web server using ASIHTTPRequest. However, videos that were shot with the iPhone held upside-down in landscape or portrait are inverted on the web server. When those uploaded videos are viewed on an iPhone, they are also scaled thy 75% or so vertically so that they appear squished.

Is there a way to determine the video orientation (including whether it was shot upside-down) of a video chosen using UIImagePickerController?

Also, is there a way to change the orientation of the video before uploading?

I’d also like to not allow uploads of video shot in portrait orientation.

Thanks

    Found the answer in anther post. AVAsset gives you two properties, [avAsset naturalSize] and [avAsset preferredTransform], that allow you to determine the video orientation.
