I am struggling to find a way to upload/publish video from the new Google Drive to (Google's) YouTube. I am trying to avoid downloading the file to my local disk and uploading it again—it's already on Google's servers!
There used to be a workaround where you send the video as an attachment to the "mobile upload" email address but the new Drive interface does not offer the option to send a video as attachment any more (at least I did not find it).
How can I do this?
