Re: Dropping MediaController in HTML5.1?

If you look at the head of that Intent to Unship mail, it's pretty clear
about the rationale:

Put MediaController behind an experimental runtime flag until the
implementation correctly integrates with the media engine.
...
MediaController was implemented in http://trac.webkit.org/changeset/100159
and is currently supported in WebKit and Chromium browsers. ...
Unfortunately, the implementation does not integrate with the media engine,
which means that the slaved media elements are not actually kept in sync.
Without this integration the API is little more than a "C++ polyfill." Had
the feature not already been shipped, I think it would be a bad idea to
ship it in its current state, since without a full implementation it's hard
to judge what the true complexity of the feature is.
...
MediaController is very rarely used and not supported in Firefox or IE, so
the risk seems very low. [I don't know if this is still true.  -cwilso]
...
Alternative implementation suggestion for web developers
In short, do whatever you do to support Firefox and IE. Simply seeking two
media elements (while paused) and playing them at the same time should give
roughly the same result as when using Blink's current MediaController
implementation.


So, in short - we don't have a good implementation, and we think we should
have a good implementation before shipping.
