This is an attempt to address the feedback in https://github.com/vector-im/element-call/pull/1099#discussion_r1226863404 that the video grid and video tile components have become too tightly coupled. After this change, the only requirements that the video grid makes of its child components are:
- They accept ref, style, and item props
- They attach the ref and styles to a react-spring animated element
Note: I removed the video grid Storybook file, because I'm not aware of anyone using Storybook for development of Element Call beyond Robert, and it would take some effort to fix to work with these changes.
So that we can load SFU with the virtual participants and get them
displayed in the grid layout. Before that only participants who are part
of the Matrix were displayed (i.e. participants who have published
m.call.member event to declare their participation).
The new grid layout has been broken ever since upgrading react-spring, because it was apparently relying on a buggy behavior of react-spring that started transitions automatically even in imperative mode. react-spring 9.5.1 fixed that behavior, which means we now need to manually start the animations.
In GroupCallView we do 'await enter()' when responding to a widget API join request, but it turns out enter wasn't actually returning a promise until now. The consequence of this was that in Element Web, when you click the join button you get shown a blank screen for a moment. This fixes that half-second moment of the UI being broken, allowing Element Web to show the intermediate 'joining' state.
This version is not supposed to properly work, this is a work in
progress.
Main changes:
* Completely removed the PTT logic (for simplicity, it could be
introduced later).
* Abstracted away the work with the media devices.
* Defined confined interfaces of the affected components so that they
only get the data that they need without importing Matris JS SDK or
LiveKit SDK, so that we can exchange their "backend" at any time.
* Started using JS/TS SDK from LiveKit as well as their React SDK to
define the state of the local media devices and local streams.
