Mh, I think you should clarify you target:
- if the target is making money than you are tied to very popular platforms, because it's only there the largest public (unfortunately);
- if the target is a selected audience you already know and they equally know you a feed publishing just new video URLs and files just dropped in a webserver suffice, you users only need to click the link to see, no web-crapplications nor WebVM (improperly named and known as browsers for legacy reasons) needed;
- if the target is personal nothing beat a storage media in your pocket...
