Turns the screenshare component into a generic component, so that it can be
used both for screenshare and camera as content fetures.
Also changes specific locales and icons for the camera as content feature.
Enables the presenter to share a camera in the presentation area.
The shared camera automatically uses a pre-defined, fixed and hidden camera.
Profile defined in the settings.yml file.
It is currently using the screenshare's backend.
Audio state callback and remote media setup both depend on FS's state
(comes through Meteor) and the ICE state (local, peer connection). The
caveat: FS's state can come delayed on reconnection scenarios because
Meteor's websocket generally takes significantly longer to re-connect than
the peer connection, which means the ICE state gets completed way before FS
is flagged as ready.
The practical issue: while outbound audio (client -> FS) will work, inbound
audio (FS -> client) won't _just because it wasn't played_ (even though
data is coming through).
This commit decouples the remote media setup step from the state
through:
- Setup remote media when ICE state is completed
- Run the state callback only after FS is flagged as ready. This
should maintain the UI states consistent across client-server.
Keep in mind the assumption that if FS is ready, ICE is completed by
consequence.
The voice user ejection callback tethered to Meteor's socket
disconnection seems broken (since its introduction). The VU selector
uses an invalid field (requesterUserId) - so no VU is ever returned.
Since I'm unaware of the original goal behind this code and there's
already ejections in place in other components (akka-apps, for
instance), this is basically a revert of #9888.
There's a scenario where remote streams won't be attached again if the
sharer experienced a Meteor/client disconnection.
The disconnection empties some necessary user data temporarily, which
causes the corresponding video-list-item to be unmounted while the peer
persists for a little longer.
If the sharer re-connects fast enough, video-list-item will re-mount but
will 1) miss the current stream state (ie stuck in loading) 2) fail to
re-attach the streams since the peer was already flagged as attached.
Ensure remote camera streams are always attached and shown by:
- always propagating the current stream state on attachment
- refactoring the attachment pre-requisites away from a static boolean
to a required data + diff check (based on target and current
attached streams)
Firefox does not support selecting an audio output device in its default
configuration. This works around this flaw by just displaying default
output instead of no device found.
