max_height	Maximum height of the input image. It is a static attribute. It cannot be changed after being set when a group is created.
pixel_format	Pixel format of the input image. For details, see hi_pixel_format. It is a static attribute. It cannot be changed after being set when a group is created. When the VPSS group ID is within the range of [0, 256), the following formats are supported: HI_PIXEL_FORMAT_YVU_SEMIPLANAR_420 and HI_PIXEL_FORMAT_YUV_SEMIPLANAR_420. When the VPSS group ID is within the range of [256, 264), the following formats are supported: HI_PIXEL_FORMAT_YVU_SEMIPLANAR_422, HI_PIXEL_FORMAT_YUV_SEMIPLANAR_422, HI_PIXEL_FORMAT_YVU_SEMIPLANAR_420, HI_PIXEL_FORMAT_YUV_SEMIPLANAR_420, and HI_PIXEL_FORMAT_YUV_400.
dynamic_range	Reserved. The value must be set to 0. For details, see hi_dynamic_range.
frame_rate	Group frame rate. For details, see hi_frame_rate_ctrl.
nr_en	Whether to enable NR. Value range: HI_FALSE: Disables this function. HI_TRUE: Enables this function.
nr_attr	NR attribute. For details, see hi_vpss_nr_attr.
reserved	Reserved. To ensure compatibility in later versions, use the memset structure for resetting and initialization. Do not explicitly access the reserved field in the code.
