If you are running IPFS on your computer to self-host videos you can also use the network directly to get content on d.tube with the IPFS Companion addon. It redirects all ipfs.io links to use the network when it detects you are running it.

Doing so will also help the videos you watch to stay online, since it stores it temporarily on your computer (you can change the storage setting). Also if you right-click a video on d.tube, it gives you the actual link to the vid (and the hash), in case for some crazy reason the original was lost.
