16 Support 2-pass (high quality) video compression scheme (Patent pending by
17 ASPEED). Provide visually lossless video compression quality or to reduce
32 Enable/Disable ASPEED's High quality mode. This is a private control
33 that can be used to enable high quality for aspeed proprietary mode.
47 Define the quality of ASPEED's High quality mode. This is a private control
48 that can be used to decide compression quality if High quality mode enabled
49 . Higher the value, better the quality and bigger the size.
