Not surprised you get fluctuations; in other experiments with JS
timing I've observed 10-15 ms delay variation just from the simple
"wait a bit" function. On my computer, the measurement is between 24.7
and 25.2 fps; if I turn off the light above my head, I get between 12
and 13.
If the drivers can't tell what the camera is currently sending,
something sensible has to happen; if the app were to open the camera
at the asked-for frame rate, and then observe the frame rate and
behave accordingly (as described above), I would call that sensible -
if opening a variable-rate camera in a dark room with frameRate: {
min: 30 }, this will cause an instant overconstrained event - but
that's what you asked for, so you should get it.
