I have gone through all of the YouTube embed issue threads and have found a lot of suggestions on making it work, but I still get the Video Upload failed. This has happened with several videos, and is not affected by the poster disabling embedding. the URL is correctly formatted. NO white space. This has happened on two fresh installs on the same shared web host through GoDaddy (I know, my client wn't leave them). GoDaddy says all of the appropriate ports are open, but they will not allow FFMPEG. Is FFMPEG required for YouTube embedding?
