Can you remove MIMETypeRegistry::isSupportedMediaSourceMIMEType now?

We will have to modify this again for MediaStream so this one bool won't last long. Why not just pass the MediaEngineSupportParameters struct?

Sure can.

Good plan.  I'll do that!

It broke the EFL build:

Could you fix it please?

Does the EFL builder not support empty initializer lists for structs?

[Csaba Osztrogonác]

I don't know ... cc-ing the EFL bot maintainers, they can answer it.
(Otherwise EWS bots are to signal this kind of build failures.)

[Csaba Osztrogonác]

I checked, it isn't a gcc bug:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55805

[Jer Noble]

Okay, I'll convert this from a POD struct to one with a default constructor.
