| Allocates an image object. More... | |
| void | NvMediaImageDestroy (const NvMediaImage *image) |

| Gets the global capture timestamp of the image. More... | |
| NvMediaStatus | NvMediaImageLock (const NvMediaImage *image, NvMediaImageLockAccess lockAccessType, NvMediaImageSurfaceMap *surfaceMap) |
| Locks an image and returns the associated mapped pointers to the image surface data. More... | |
| void | NvMediaImageUnlock (const NvMediaImage *image) |
| Unlocks an image. More... | |
| NvMediaStatus | NvMediaImagePutBits (NvMediaImage *image, const NvMediaRect *dstRect, void **srcPntrs, const uint32_t *srcPitches) |
