Parameters

[in]	stream	A stream handle where the operation will be queued into.
[in]	backend	Backend that will execute the algorithm. Valid values: VPI_BACKEND_CPU VPI_BACKEND_CUDA VPI_BACKEND_VIC
[in]	input	Input image to be flipped. CPU and CUDA accept all pitch-linear image formats, with at most 4 planes. Valid Image formats for VIC backend: VPI_IMAGE_FORMAT_Y8 VPI_IMAGE_FORMAT_Y8_ER VPI_IMAGE_FORMAT_RGBA8 VPI_IMAGE_FORMAT_BGRA8 VPI_IMAGE_FORMAT_NV12 VPI_IMAGE_FORMAT_NV12_ER VPI_IMAGE_FORMAT_NV24 VPI_IMAGE_FORMAT_NV24_ER VPI_IMAGE_FORMAT_UYVY VPI_IMAGE_FORMAT_UYVY_ER VPI_IMAGE_FORMAT_YUYV VPI_IMAGE_FORMAT_YUYV_ER VPI_IMAGE_FORMAT_Y8_BL VPI_IMAGE_FORMAT_Y8_ER_BL VPI_IMAGE_FORMAT_NV12_BL VPI_IMAGE_FORMAT_NV12_ER_BL VPI_IMAGE_FORMAT_NV24_BL VPI_IMAGE_FORMAT_NV24_ER_BL VPI_IMAGE_FORMAT_UYVY_BL VPI_IMAGE_FORMAT_UYVY_ER_BL VPI_IMAGE_FORMAT_YUYV_BL VPI_IMAGE_FORMAT_YUYV_ER_BL VPI_IMAGE_FORMAT_Y8_BL16 VPI_IMAGE_FORMAT_Y8_ER_BL16 VPI_IMAGE_FORMAT_NV12_BL16 VPI_IMAGE_FORMAT_NV12_ER_BL16 VPI_IMAGE_FORMAT_NV24_BL16 VPI_IMAGE_FORMAT_NV24_ER_BL16 VPI_IMAGE_FORMAT_UYVY_BL16 VPI_IMAGE_FORMAT_UYVY_ER_BL16 VPI_IMAGE_FORMAT_YUYV_BL16 VPI_IMAGE_FORMAT_YUYV_ER_BL16 Images whose format has either 4:2:0 or 4:2:2 chroma subsampling must have even dimensions.
[out]	output	Output image where the result will be written to. It must have the same format and dimensions as input.
[in]	flipMode	Direction the image needs to be flipped in. Accepted inputs: VPI_FLIP_HORIZ VPI_FLIP_VERT VPI_FLIP_BOTH

VPI_ERROR_INVALID_ARGUMENT	flipMode is not valid.
VPI_ERROR_INVALID_ARGUMENT	backend is invalid or unknown.
VPI_ERROR_INVALID_IMAGE_FORMAT	input and output formats aren't supported
VPI_ERROR_NOT_IMPLEMENTED	Image Flip algorithm is not supported by given backend.
VPI_ERROR_INVALID_OPERATION	Backend hardware not available.
VPI_ERROR_INVALID_OPERATION	The needed backends aren't enabled in stream, input or output.
