murillo128 has just created a new issue for https://github.com/w3c/mediacapture-image:

== Add support for powerline frequency on gUM MediaTrackSupportedConstraints ==
AFAIK there is no way to control the power line frequency of the video capture device to reduce the light flickering.

The idea would be to add a new `powerLineFrequency` constraint that can take the following values:

- Auto: The power-line frequency is determined automatically by the system.
- Disabled : Power-line frequency control is disabled.
- 50Hz: The power-line frequency is 50 Hz.
- 60Hz: The power-line frequency is 60 Hz.
