Gets the label detection results of a Rekognition Video analysis started by .
The label detection operation is started by a call to which returns a job identifier (JobId
). When the label detection operation finishes, Amazon Rekognition publishes a completion status to the Amazon Simple Notification Service topic registered in the initial call to StartlabelDetection
. To get the results of the label detection operation, first check that the status value published to the Amazon SNS topic is SUCCEEDED
. If so, call and pass the job identifier (JobId
) from the initial call to StartLabelDetection
.
GetLabelDetection
returns an array of detected labels (Labels
) sorted by the time the labels were detected. You can also sort by the label name by specifying NAME
for the SortBy
input parameter.
The labels returned include the label name, the percentage confidence in the accuracy of the detected label, and the time the label was detected in the video.
Use MaxResults parameter to limit the number of labels returned. If there are more results than specified in MaxResults
, the value of NextToken
in the operation response contains a pagination token for getting the next set of results. To get the next page of results, call GetlabelDetection
and populate the NextToken
request parameter with the token value returned from the previous call to GetLabelDetection
.

Creating a Request
Creates a value of GetLabelDetection
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
gldNextToken
- If the previous response was incomplete (because there are more labels to retrieve), Rekognition Video returns a pagination token in the response. You can use this pagination token to retrieve the next set of labels.gldMaxResults
- Maximum number of results to return per paginated call. The largest value you can specify is 1000. If you specify a value greater than 1000, a maximum of 1000 results is returned. The default value is 1000.gldSortBy
- Sort to use for elements in theLabels
array. UseTIMESTAMP
to sort array elements by the time labels are detected. UseNAME
to alphabetically group elements for a label together. Within each label group, the array element are sorted by detection confidence. The default sort is byTIMESTAMP
.gldJobId
- Job identifier for the label detection operation for which you want results returned. You get the job identifer from an initial call toStartlabelDetection
.

Destructuring the Response
getLabelDetectionResponse Source #
Creates a value of GetLabelDetectionResponse
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
gldrsNextToken
- If the response is truncated, Rekognition Video returns this token that you can use in the subsequent request to retrieve the next set of labels.gldrsVideoMetadata
- Information about a video that Rekognition Video analyzed.Videometadata
is returned in every page of paginated responses from a Amazon Rekognition video operation.gldrsStatusMessage
- If the job fails,StatusMessage
provides a descriptive error message.gldrsLabels
- An array of labels detected in the video. Each element contains the detected label and the time, in milliseconds from the start of the video, that the label was detected.gldrsJobStatus
- The current status of the label detection job.gldrsResponseStatus
- -- | The response status code.
