* NV_CTRL_GVI_REQUESTED_COMPONENT_SAMPLING - Specify the sampling

format for

* the captured stream.

* The possible values are the NV_CTRL_GVI_DETECTED_COMPONENT_SAMPLING

* constants.

* The stream number should be specified in the "display_mask"

parameter.

#define NV_CTRL_GVI_REQUESTED_STREAM_COMPONENT_SAMPLING 312 /*

RW-I */

* NV_CTRL_GVI_CHROMA_EXPAND - Enable or disable 4:2:2 -> 4:4:4 chroma

* expansion for the captured stream. This value is ignored when a

* COMPONENT_SAMPLING format is selected that does not use chroma
