Data Structures | |
| struct | VPIImagePlane |
| Stores information about an image plane. More... | |
| struct | VPIImageData |

Macros | |
| #define | VPI_MAX_PLANE_COUNT (6) |
| Maximum number of data planes an image can have. | |
Image-specific flags. | |
| #define | VPI_DISABLE_BL_HOST_LOCK (1u << 31) |
| Flag to allow vpiImageLock of block-linear images to succeed. More... | |
Functions | |
| VPIStatus | vpiImageCreate (int32_t width, int32_t height, VPIImageFormat fmt, uint32_t flags, VPIImage *img) |
| Create an empty image instance with the specified flags. More... | |
| VPIStatus | vpiImageCreateHostMemWrapper (const VPIImageData *hostData, uint32_t flags, VPIImage *img) |
| Create an image object by wrapping around an existing host memory block. More... | |
| VPIStatus | vpiImageSetWrappedHostMem (VPIImage img, const VPIImageData *hostData) |
| Redefines the wrapped host memory in an existing VPIImage wrapper. More... | |
| void | vpiImageDestroy (VPIImage img) |
| Destroy an image instance. More... | |
| VPIStatus | vpiImageInvalidate (VPIImage img) |
| Informs that the image's wrapped memory was updated outside VPI. More... | |
| VPIStatus | vpiImageGetSize (VPIImage img, int32_t *width, int32_t *height) |
| Get the image size in pixels. More... | |
| VPIStatus | vpiImageGetFormat (VPIImage img, VPIImageFormat *format) |
| Get the image format. More... | |
| VPIStatus | vpiImageGetFlags (VPIImage img, uint32_t *flags) |
| Get the image flags. More... | |
| VPIStatus | vpiImageLock (VPIImage img, VPILockMode mode, VPIImageData *hostData) |
| Acquires the lock on an image object and returns a pointer to the image planes. More... | |
| VPIStatus | vpiImageUnlock (VPIImage img) |
| Releases the lock on an image object. More... | |
