Re: Bug 23934 - Proposal: Always launch permission prompt to avoid leakage

I think my views are quite similar to Martin's.

I think that perhaps we could leave a lot of this up to implementations 
(e.g. what kind of info is displayed if no device that meets the 
mandatory constraints is available). For the case were suitable devices 
are found, the current draft says "Prompt the user in a user agent 
specific manner for permission...". We can use similar phrasing for 
cases when no devices that meet mandatory constraints are found.

This question is not related to the "Always launch permission prompt" 
proposal per se, it is related to mandatory constraints used with gUM.

It is something we need to agree on; and the first level we need to 
agree on is whether this must be specified or can be left to the UA to 
decide.

Perhaps we do not need to spec this, perhaps something like "Inform the 
user in a user agent specific manner that the page asked for access to 
cameras/microphones but that no devices that met the requirements were 
found." is enough.

Of course not. The first level of constraints with gUM is "audio" or 
"video", and you can't use one in place of the other.
