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
