I use PrimCast as my videohost, it take a little time to get approved and the video manager is run by Kaltura Community Edition server.

Now I have covered this in a different post, but in order for the .json, .rss, or xml to ingest you will need a static website. You can get a free one from github Easy step, login or create an account. Create a Repository if you have not already done so, and then click the gear at the top and at the bottom enable Github Pages and choose a theme and hit save.. All you need is a .md file and this will be the page people see when visiting.
How simple is up to you, the page is generated by a format called Jekyl themes which I am still learning about. Last, I implore make life easy and just download the Json Feed Manager or MRSS feed Manager. Trust me when i say, he really did all the work to make managing and creating a feed a miracle.
