The protocol itself has gone through a number of major revisions (it's currently on [version 7](https://tools.ietf.org/html/draft-pantos-http-live-streaming-18)) and it's possible that not all `<video>` implementations would support all versions of the protocol. There doesn't seem a clear mechanism in [RFC-6381](https://tools.ietf.org/html/rfc6381) for expressing this aspect of media formats.
