NV_CTRL_GVO_OUTPUT_VIDEO_FORMAT
/*
* NV_CTRL_GVO_OUTPUT_VIDEO_FORMAT - specifies the output video
* format. Note that the valid video formats will 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_GVO_OUTPUT_VIDEO_FORMAT to check
* which of the first 31 VIDEO_FORMATS are valid, then query the
* ValidValues for NV_CTRL_GVO_OUTPUT_VIDEO_FORMAT2 to check which of
* the VIDEO_FORMATS with value 32 and higher are valid.
