Motion() chokes on rotated video files #289

Closed alexarje closed 1 year ago

I just discovered that motion() doesn't like video files that have been rotated in metadata (description here). Would be good to check for this somehow.

This was due to the fact that when rotating a video with ffmpeg by only modifying the metadata in the file, the height and the width used for the motion() function were not updated. I have updated the get_widthheight() function so that it first checks if the video has been rotated by 90 degrees, and if yes it inverts the values corresponding to width and height.
