The supplied encoding must be one of the encodings listed for the adaptor, otherwise an Encoding error results.
If the adaptor does not support the exact hue, saturation, brightness, and contrast levels supplied, the closest levels supported are assumed. Use XvGetPortAttribute(3X) to query the resulting levels.
When an XvSetPortAttribute(3X) request is processed, a PortControlNotify(3X) event is generated for all clients that have requested for port changes using XvSelectPortNotify(3X).
