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 and value must be set to 0.
frame_rate	Group frame rate.
nr_en	Whether to enable NR. The options are as follows: HI_FALSE: disabled. HI_TRUE: enabled.
