[Galene] Re: Camera test for Galene

[Juliusz Chroboczek <jch@irif.fr>]

I've played with it some more, and here's the current plan for the UI.

Below the login dialog, there's what Mac people call a "disclosure
indicator":

    ▶ Test camera and microphone

When the user clicks on the triangle, the browser produces its permissions
dialog.  If the user rejects the permission dialog, we remain in the
folded state.  If the user accepts, the indicator unfolds (▼), and the UI
for the video test is shown.  If the user clicks on the triangle again,
the camera is released, and we return to the initial state.

Do people feel that's discoverable enough for a naive user?

Related question, do people feel that the Fourier transform (spectrograph)
display is too geeky, and that I should replace it with a simple volume
indicator (0% — 100%)?

I also think I need to display a big red message that says "no audio, your
microphone might be muted", but I need to do some experimenting in order
to find out how to determine that reliably from the Fourier transform.
(I'm currently requesting the browser to compute the Fourier transform,
not the RMS, and I'd rather not be computing both.)
