Describe the bug

I'm trying to stream the video to a v4l2 loopback device. Everything seems to work fine except when using the options --no-display --turn-screen-off at the same. There is no windowed display as expected, however the phone screen does not get turned off.

On using the options one at a time everything works as expected.

I've tried it with another device (PANASONIC ELUGA Turbo (Android 5.1)). Still the same issue persists.
