is any of this really being merged back to 23?  
do you really need to care about versioning as long as nobody's using
internally, and it's in the private/ dir?

[Tom Finegan, 2012/10/08 23:23:27]

I don't think so. Changed to M24.
Brettw asked that I increase the version number for the last interface change. I
don't really know what the policy is on versioning of these interfaces.

[Ami GONE FROM CHROMIUM, 2012/10/09 07:21:12]

Policy is "do what brettw says" ;)

Doesn't versioning require marking the method as being new in 0.3 or something?

[Tom Finegan, 2012/10/08 23:23:27]

Agreed, but media is the only client using this interface (via PluginInstance).
I don't think it's necessary to add versioning information here until after
we've completed the whole interface (i.e. this CL + the audio version of the
same). 

[Ami GONE FROM CHROMIUM, 2012/10/09 07:21:12]

I don't understand your statement, but I'll let you hash it out w/ brettw.

This name is a little bit strange. How about DecoderInitialized() or
OnDecoderInitialized()?

[Tom Finegan, 2012/10/08 23:23:27]

Done.
