This is a surprisingly complex upgrade. Some relevant changes from
[their CHANGELOG](https://github.com/mui-org/material-ui/blob/v5.0.0-beta.3/CHANGELOG.md):
* @material-ui/core/styles no longer re-exports some stuff from
@material-ui/styles
* there's no more defaultTheme, so tests need to provide one
* select's onChange has a new type; match that. I haven't actually
tried that the string form (apparently from autofill) works correctly.
* checkboxes no longer default to the secondary color; explicitly
request this in some places.
* checkbox no longer has a checked argument; use event.target.checked
instead.
* date pickers have switched to the new style system, so I had to
redo how I was overridding their spacing for desktop.
* LoadingButton now has a loading property, not pending
* createMuiTheme is no createTheme
It's a start. It can display several streams at once, which is nice.
There are lots of opportunities for improvement:
* it doesn't keep the videos approximately in sync.
* it accumulates extra buffering, drifting behind live. This is
particularly noticeable when it's paused and played again; it can
be several seconds before it jumps to after the break.
* it always uses the sub stream rather main. I'd prefer it support
"auto" (use main if the viewport is larger than the sub stream and
there's sufficient bandwidth), "main", or "sub".
* it has a kludgy heuristic where it throws away everything buffered 5
seconds before the current timestamp. It should throw away
everything before the current GOP instead, but I need to alter the
API so it can easily know when that is.
* it can't tell you when a camera connection is down. This needs an
API change also.
* it'd be nice to quickly double-click on a stream to view only it,
then double-click again to go back to the multi-pane view.
* it doesn't allow you to zoom in on part of the video. This would be
nice particularly when viewing 4k video streams on small screens.
* it has only four preconfigured layouts that subdivide a 16x9
viewport. You have to choose every camera every time. It'd be nice
to both allow more flexibility and have more memory.

This reverts commit d273a99f83.
This accidentally increased the density by making my global CSS
overrides ineffective. I'm struggling to achieve both, and I'd rather
have my desired sizing.
Looks like material-ui's `<Select variant="outlined">` needs a redundant
label property to make the layout correct.
https://next.material-ui.com/api/outlined-input/#main-content
"The label of the input. It is only used for layout. The actual
labelling is handled by InputLabel. If specified labelWidth is ignored."
* 1-hour videos are a bit faster to render server-side and don't
require so much index data to be transferred before play starts
* the timestamp tracks might be causing a lot of excess data transfer
in some cases. They're currently not interleaved by ascending
timestamp, and I wonder if they should be. Chrome might be pulling
all the bytes between the current position in the two tracks, which
can be excessive. I'll have to consider interleaving when I add
audio anyway. But for now, just make the default UI display
snappier. Chrome doesn't display the timestamp track anyway, so
don't let it slow things down.
Once I have more than one area of the UI (e.g., adding config, live
video, or a scrub bar prototype), I'll use this for a pull-down menu to
go between them, and maybe add a filter icon to do what this does. But
this works for now and most closely matches the old UI.
I tried to use a Collapse or Slide transition, but I had trouble getting
it to work on both desktop and mobile. In particular, the way I used the
flex wrap to display the selectors on the left/above doesn't seem
compatible with picking an orientation. If I pick the wrong orientation,
the list views won't fill the empty space.
* hide the end day selector away when it's not in use.
It was confusing, especially since it seemed to have
a purely black circle over the selected date when disabled.
* add a "Time" label to the time selectors. On desktop,
this isn't entirely necessary because they have clock icons
and "hh:mm:ss" annotations. But on mobile, they were entirely blank,
so it was unclear what they were for.
