Functions | |
| VPIStatus | vpiImageCreate (uint32_t width, uint32_t height, VPIImageType type, uint32_t flags, VPIImage *img) |
| Create an empty image instance with the specified flags. More... | |
| VPIStatus | vpiImageWrapHostMem (const VPIImageData *hostData, uint32_t flags, VPIImage *img) |
| Create an image object by wrapping around an existing host-memory block. More... | |
| VPIStatus | vpiImageWrapCudaDeviceMem (const VPIImageData *cudaData, uint32_t flags, VPIImage *img) |
| Create an image object by wrapping around an existing device-memory (CUDA) block. More... | |
| VPIStatus | vpiImageWrapNvBuffer (int dmabuf_fd, uint32_t flags, VPIImage *pimg) |
| Create an image object by wrapping an existing NvBuffer given its dmabuf_fd handle. More... | |
| void | vpiImageDestroy (VPIImage img) |
| Destroy an image instance as well as all resources it owns. More... | |
| VPIStatus | vpiImageInvalidate (VPIImage img) |
This method is useful for unmanaged images only (created with vpiImageWrap*). More... | |
| VPIStatus | vpiImageGetSize (VPIImage img, uint32_t *width, uint32_t *height) |
| Get the image size in pixels. More... | |
| VPIStatus | vpiImageGetType (VPIImage img, VPIImageType *type) |
| Get the image type. 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 Depending on the internal image representation, as well as the actual location in memory, this function might have a significant performance overhead (format conversion, layout conversion, device-to-host memory copy). More... | |
| VPIStatus | vpiImageUnlock (VPIImage img) |
| Releases the lock on an image object. More... | |
