You need to check with V4L utilities or ffmpeg, which formats /
resolutions your v4l2 device provides. I would guess that docker gives
you only an abstraction (it's a kind of virtualization, right?).
Perhaps you only get USB 1.1, and that doesn't allow for your device's
larger resolutions (despite "-r 1"). Hmm, just guessing.
