- DONE: implement receiving hangup
- DONE: implement cloning the localMedia so it works in safari?
- DONE: implement 3 retries per peer
- implement muting tracks with m.call.sdp_stream_metadata_changed
- implement renegotiation
- making logging better
- DONE: implement muting tracks with m.call.sdp_stream_metadata_changed
- DONE: implement renegotiation
- DONE: finish session id support
- call peers are essentially identified by (userid, deviceid, sessionid). If see a new session id, we first disconnect from the current member so we're ready to connect with a clean slate again (in a member event, also in to_device? no harm I suppose, given olm encryption ensures you can't spoof the deviceid).
- making logging better
- figure out why sometimes leave button does not work
- get correct members and avatars in call
- improve UI while in a call
- allow toggling audio
- support active speaker, sort speakers by last active
- close muted media stream after a while
- support highlight mode where we show active speaker and thumbnails for other participants
- better grid mode:
- we report the call view size to the view model with ResizeObserver, we calculate the A/R
- we calculate the grid based on view A/R, taking into account minimal stream size
- show name on stream view
- when you start a call, or join one, first you go to a SelectCallMedia screen where you can pick whether you want to use camera, audio or both:
- if you are joining a call, we'll default to the call intent
- if you are creating a call, we'll default to video
- when creating a call, adjust the navigation path to room/room_id/call
- when selecting a call, adjust the navigation path to room/room_id/call/call_id
- implement to_device messages arriving before m.call(.member) state event
- DONE for m.call.member, not for m.call and not for to_device other than m.call.invite arriving before invite
- reeable crypto & implement fetching olm keys before sending encrypted signalling message
- local echo for join/leave buttons?
- make UI pretsy
- figure out video layout
- figure out nav structure
- batch outgoing to_device messages in one request to homeserver for operations that will send out an event to all participants (e.g. mute)
- implement call ringing and rejecting a ringing call
- support screen sharing
- add button to enable, disable
- support showing stream view with large screen share video element and small camera video element (if present)
- don't load all members when loading calls to know whether they are ringing and joined by ourself
- only load our own member once, then have a way to load additional members on a call.
- see if we remove partyId entirely, it is only used for detecting remote echo which is not an issue for group calls? see https://github.com/matrix-org/matrix-spec-proposals/blob/dbkr/msc2746/proposals/2746-reliable-voip.md#add-party_id-to-all-voip-events
- remove PeerCall.waitForState ?
- invite glare is completely untested, does it work?
- how to remove call from m.call.member when just closing client?
- when closing client and still in call, tell service worker to send event on our behalf?
```js
// dispose when leaving call
this.track(platform.registerExitHandler(unloadActions => {
// batch requests will resolve immediately,
// so we can reuse the same send code that does awaits without awaiting?
const batch = new RequestBatch();
const hsApi = this.hsApi.withBatch(batch);
// _leaveCallMemberContent will need to become sync,
// so we'll need to keep track of own member event rather than rely on storage
hsApi.sendStateEvent("m.call.member", this._leaveCallMemberContent());
// does this internally: serviceWorkerHandler.trySend("sendRequestBatch", batch.toJSON());
unloadActions.sendRequestBatch(batch);
