Shouldn't this be const ?

Why is this ? For a non-raw stream, why would we reject an invalid
format instead of adjusting it when there's a sensor configuration ?

Is this check needed ?

Below we have
maxResolution = maxResolution_.boundedToAspectRatio(resolution)
.boundedTo(resolution);
Is there a reason why you swap the calls here ?
