Indexable Video Distribution Platform

Hola community!
Hope this is appropriate to post this question here. Being that we can export as SCORM/Web/Video from SL, was wondering if something like this exists. 

A video distribution platform. Able to house existing embedded Youtube and Wistia videos, along with MP4s.
- Tag ability
- Closed Captions
- Searchable/indexable
- Localization

I know this is screaming YouTube but need to be able to have it branded. Appreciate your time/expertise!
