[英]Rotate Video after picked from UIImagePickerController to upload to server
So I've seen these answers and many others: 因此,我已经看到了这些答案以及许多其他答案:
How to detect (iPhone SDK) if a video file was recorded in portrait orientation, or landscape. 如何检测(iPhone SDK)视频文件是以纵向还是横向录制的。
How do I rotate a video from UIImagePickerController before uploading to a webserver 在上传到Web服务器之前,如何旋转UIImagePickerController中的视频
I understand how to get the orientation of the video from the UIImagePickerController but How do I actually rotate the video url that the Image Picker returns so when I upload it its not rotated 90 degrees? 我了解如何从UIImagePickerController获取视频的方向,但是如何实际旋转图像选择器返回的视频网址,以便在上载时未旋转90度的视频网址?
EDIT: 编辑:
I'm using this method to get the orientation of the video. 我正在使用这种方法来获取视频的方向。 After I get the videos orientation how do I actually rotate it to that returned orientation?
确定视频方向后,如何将其实际旋转到返回的方向?
