React Native doesn't define __filename nor __dirname so do it artisanally. In
addition, this helps with centralizing the configuration passed to loggers.
This refactors all handling of audio-only and last N to 2 features in preparation
for "low bandwidth mode".
The main motivation to do this is that lastN is a "global" setting so it helps
to have all processing for it in a single place.
For the most part the changes are taking the "static propTypes" declaration off
of components and declaring them as Flow types. Sometimes to support flow some
method signatures had to be added. There are some exceptions in which more had
to be done to tame the beast:
- AbstractVideoTrack: put in additional truthy checks for videoTrack.
- Video: add truthy checks for the _videoElement ref.
- shouldRenderVideoTrack function: Some component could pass null for the
videoTrack argument and Flow wanted that called out explicitly.
- DisplayName: Add a truthy check for the input ref before acting on it.
- NumbersList: Move array checks inline for Flow to comprehend array methods
could be called. Add type checks in the Object.entries loop as the value is
assumed to be a mixed type by Flow.
- AbstractToolbarButton: add additional truthy check for passed in type.
Move away from middleware and instead update video quality
when the selected video quality updates in redux. This also
lead to removing of automatically exiting audio only because
with the change it's not so readily possible to tell if the
user switched off audio only by re-selecting the already
preferred video quality. Removing this automagic removed
some additional checking done for mobile.
- "preferred" is being appended because in tile view there is a
concept of what the user prefers to be the maximum video quality
but there is also a maximum respected internall. For example,
the user may prefer HD, but in tile view the tiles may be small
so internall the preferred would be set to LD.
- "receive" is being renamed to "receiver" to be consistent with
the naming in lib-jitsi-meet.
