Subject: short-circuit permissions checks in MediaStreamDevicesController
|
|
|
|
The //components/permissions architecture is complicated and not that
|
|
widely used in Chromium, and mostly oriented around showing permissions
|
|
UI and/or remembering per-site permissions, which we're not interested
|
|
in.
|
|
|
|
Since we do a permissions check prior to invoking the
|
|
MediaStreamDevicesController, and don't (yet) provide the ability to set
|
|
granular permissions (e.g. allow video but not audio), just
|
|
short-circuit all the permissions checks in MSDC for now to allow us to
|
|
unduplicate this code.
