start-content-moderation

Description

Starts asynchronous detection of unsafe content in a stored video.

Amazon Rekognition Video can moderate content in a video stored in an Amazon S3 bucket. Use Video to specify the bucket name and the filename of the video. StartContentModeration returns a job identifier (JobId ) which you use to get the results of the analysis. When unsafe content analysis is finished, Amazon Rekognition Video publishes a completion status to the Amazon Simple Notification Service topic that you specify in NotificationChannel .

To get the results of the unsafe content analysis, first check that the status value published to the Amazon SNS topic is SUCCEEDED . If so, call GetContentModeration and pass the job identifier (JobId ) from the initial call to StartContentModeration .

For more information, see Detecting Unsafe Content in the Amazon Rekognition Developer Guide.

Options

--video (structure)

The video in which you want to detect unsafe content. The video must be stored in an Amazon S3 bucket.

S3Object -> (structure)

The Amazon S3 bucket name and file name for the video.

Bucket -> (string)

Name of the S3 bucket.

Name -> (string)

S3 object key name.

Version -> (string)

If the bucket is versioning enabled, you can specify the object version.

Shorthand Syntax:

S3Object={Bucket=string,Name=string,Version=string}

JSON Syntax:

{
  "S3Object": {
    "Bucket": "string",
    "Name": "string",
    "Version": "string"
  }
}

--min-confidence (float)

Specifies the minimum confidence that Amazon Rekognition must have in order to return a moderated content label. Confidence represents how certain Amazon Rekognition is that the moderated content is correctly identified. 0 is the lowest confidence. 100 is the highest confidence. Amazon Rekognition doesn’t return any moderated content labels with a confidence level lower than this specified value. If you don’t specify MinConfidence , GetContentModeration returns labels with confidence values greater than or equal to 50 percent.

--client-request-token (string)

Idempotent token used to identify the start request. If you use the same token with multiple StartContentModeration requests, the same JobId is returned. Use ClientRequestToken to prevent the same job from being accidently started more than once.

--notification-channel (structure)

The Amazon SNS topic ARN that you want Amazon Rekognition Video to publish the completion status of the unsafe content analysis to.

SNSTopicArn -> (string)

The Amazon SNS topic to which Amazon Rekognition to posts the completion status.

RoleArn -> (string)

The ARN of an IAM role that gives Amazon Rekognition publishing permissions to the Amazon SNS topic.

Shorthand Syntax:

SNSTopicArn=string,RoleArn=string

JSON Syntax:

{
  "SNSTopicArn": "string",
  "RoleArn": "string"
}

--job-tag (string)

An identifier you specify that’s returned in the completion notification that’s published to your Amazon Simple Notification Service topic. For example, you can use JobTag to group related jobs and identify them in the completion notification.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples

To start the recognition of unsafe content in a stored video

The following start-content-moderation command starts a job to detect unsafe content in the specified video file stored in an Amazon S3 bucket.

aws rekognition start-content-moderation \
    --video "S3Object={Bucket=MyVideoS3Bucket,Name=MyVideoFile.mpg}"

Output:

{
    "JobId": "1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef"
}

For more information, see Detecting Unsafe Stored Videos in the Amazon Rekognition Developer Guide.

Output

JobId -> (string)

The identifier for the unsafe content analysis job. Use JobId to identify the job in a subsequent call to GetContentModeration .
