* NV_CTRL_GVO_SYNC_SOURCE - if NV_CTRL_GVO_SYNC_MODE is set to either

* GENLOCK or FRAMELOCK, this controls which sync source is used as

* the incoming sync signal (either Composite or SDI). If

* NV_CTRL_GVO_SYNC_MODE is FREE_RUNNING, this attribute has no

* effect.

* NV_CTRL_GVIO_REQUESTED_VIDEO_FORMAT - specifies the desired output

video

* format for GVO devices or the desired input video format for GVI

devices.

* Note that for GVO, the valid video formats may vary depending on

* the NV_CTRL_GVO_SYNC_MODE and the incoming sync video format. See

* the definition of NV_CTRL_GVO_SYNC_MODE.

* Note that when querying the ValidValues for this data type, the

* values are reported as bits within a bitmask

* (ATTRIBUTE_TYPE_INT_BITS); unfortunately, there are more valid

* value bits than will fit in a single 32-bit value. To solve this,

* query the ValidValues for NV_CTRL_GVIO_OUTPUT_VIDEO_FORMAT to check

* which of the first 31 VIDEO_FORMATS are valid, then query the

* ValidValues for NV_CTRL_GVIO_OUTPUT_VIDEO_FORMAT2 to check which of

* the VIDEO_FORMATS with value 32 and higher are valid.
