WTFMove(context)

Nit: '*' on the wrong side.

Ditto

Is this for audio output only?

Nit. The space between [] and () can be removed.

Nit. An extra space.

> Source/WebCore/platform/graphics/cocoa/MediaEngineConfigurationFactoryCocoa.cpp:133
> +            if (!context || !WTF::allOf(context->outputDevices(), [] (auto& device) {

Nit. The space between [] and () can be removed.

Not necessarily; it is also used for remote video playback over AirPlay or through an external TV screen.

Won't the style checker complain about that?
