| ) |
Return embedded data stored in a captured image.
Embedded data can be added to the following image types. This type must obtained by /ref NvMediaSurfaceFormatGetType with: NVM_SURF_FMT_SET_ATTR_YUV(attr, YUYV, 422, PACKED, UINT, 8, PL) NVM_SURF_FMT_SET_ATTR_RGBA (attr, RGBA, UINT, 8, [PL|BL]) NVM_SURF_FMT_SET_ATTR_RAW (attr, [RGGB/BGGR/GRBG/GBRG], INT, [8/10/12/16/20], PL) NVM_SURF_FMT_SET_ATTR_RAW (attr, [RCCB/BCCR/CRBC/CBRC], INT, 12, PL) NVM_SURF_FMT_SET_ATTR_RAW (attr, [RCCC/CCCR/CRCC/CCRC], INT, 12, PL)
| [in] | image | Image to get the embedded data from. |
| [in] | imageIndex | Index of the sub-image in case of multi-image handle. For single image this parameter is ignored. Index count starts from 0. |
| [in] | embeddedBufTop | The buffer where the top embedded data is stored. |
| [in] | embeddedBufTopSize | Pointer to top buffer size. The actual size of copied data will be returned in this parameter. |
| [in] | embeddedBufBottom | The buffer where the bottom embedded data is stored. |
| [in] | embeddedBufBottomSize | Pointer to bottom buffer size. The actual size of copied data will be returned in this parameter. |
| NvMediaStatus NvMediaImageGetGlobalTimeStamp | ( | NvMediaImage * | image, |
| NvMediaGlobalTime * | globalTimeStamp | ||
| ) |
Gets the global capture time-stamp of the image.
The global time-stamp is set by the NvMedia IPP Capture component.
| [in] | image | A pointer to the image for which to get the time-stamp. |
| [in] | globalTimeStamp | A pointer to the global capture timestamp of the image. Possible values are: NVMEDIA_STATUS_OK Success NVMEDIA_STATUS_BAD_PARAMETER If image or timeStamp is NULL NVMEDIA_STATUS_ERROR If any error occurred |
| NvMediaStatus NvMediaImageGetStatus | ( | NvMediaImage * | image, |
| uint32_t | millisecondWait, | ||
| NvMediaTaskStatus * | status | ||
| ) |
Gets status of the current/last operation for the image, and optionally waits for operation to complete/timeout.
| [in] | image | A pointer to the image. |
| [in] | millisecondWait | Time in milliseconds to wait for operation to complete before getting status. NVMEDIA_IMAGE_TIMEOUT_INFINITE means wait till operation is completed and then get status. |
| [out] | status | Status of the operation. |
| NvMediaStatus NvMediaImageGetTimeStamp | ( | NvMediaImage * | image, |
| NvMediaTime * | timeStamp | ||
| ) |
Gets the capture timestamp of the image.
| [in] | image | A pointer to the image for which to get the timestamp. |
| [in] | timeStamp | A pointer the capture timestamp of the image. |
