GTK failure is legit and due to difference of -expected.txt files, I'll fix that. Putting as r? while waiting for iOS results.

It would be nice to improve this eventually so we apply a union of the constraints, so we always capture at the highest requested constraint values and decimate/downsample as necessary. Maybe add a FIXME?

I would be cleaner to have the compile flag in a method (`canCaptureFromMultipleCameras`?).

RealtimeVideoCaptureSource does this for width, height and frameRate.
This should ensure there is no functionality regression.

Instead of introducing this boolean, I'll add a dedicated method instead.
