ParseLiveStreamProcessNotification

最后更新时间:2024-12-17 12:08:32

    1. API Description

    Domain name for API request: mps.intl.tencentcloudapi.com.

    This API is used to parse the content of an MPS live stream processing event notification from the msgBody field in the message received from CMQ.
    Instead of initiating a video processing task, this API is used to help generate SDKs for various programming languages. You can parse the event notification based on the analytic function of the SDKs.

    A maximum of 20 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    2. Input Parameters

    The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

    Parameter Name Required Type Description
    Action Yes String Common Params. The value used for this API: ParseLiveStreamProcessNotification.
    Version Yes String Common Params. The value used for this API: 2019-06-12.
    Region No String Common Params. This parameter is not required for this API.
    Content Yes String Live stream event notification obtained from CMQ.

    3. Output Parameters

    Parameter Name Type Description
    NotificationType String Live stream processing result type, including:
  • AiReviewResult: content auditing result.
  • AiRecognitionResult: content recognition result.
  • LiveRecordResult: live recording result.
  • AiQualityControlResult: media quality inspection result.
  • ProcessEof: live stream processing result.
  • TaskId String Video processing task ID.
    ProcessEofInfo LiveStreamProcessErrorInfo Information of a live stream processing error, which is valid when NotificationType is ProcessEof.
    Note: when this field return null, means no valid values can be obtained.
    AiReviewResultInfo LiveStreamAiReviewResultInfo Content audit result, which is valid when NotificationType is AiReviewResult.
    Note: when this field return null, means no valid values can be obtained.
    AiRecognitionResultInfo LiveStreamAiRecognitionResultInfo Content recognition result, which is valid if NotificationType is AiRecognitionResult.
    AiAnalysisResultInfo LiveStreamAiAnalysisResultInfo Content analysis result, which is valid if NotificationType is AiAnalysisResult.
    AiQualityControlResultInfo LiveStreamAiQualityControlResultInfo Media quality inspection result, which is valid if NotificationType is AiQualityControlResult.
    LiveRecordResultInfo LiveStreamRecordResultInfo Live recording result is valid when NotificationType is LiveRecordResult.
    Note: when this field return null, means no valid values can be obtained.
    SessionId String The ID used for deduplication. If there was a request with the same ID in the last seven days, the current request will return an error. The ID can contain up to 50 characters. If this parameter is left empty or an empty string is entered, no deduplication will be performed.
    SessionContext String The source context which is used to pass through the user request information. The task flow status change callback will return the value of this field. It can contain up to 1,000 characters.
    Timestamp Integer - Expiration time, event notification signature expiration UNIX timestamp. - By default, notifications sent by MPS expire after 10 minutes. If the expiration time specified has elapsed, a notification will be considered invalid. This can prevent replay attacks. - The format of Timestamp is a decimal UNIX timestamp, which is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT).
    Note: This field may return null, indicating that no valid value can be obtained.
    Sign String Event notification security signature. Sign = MD5 (Timestamp + NotifyKey). Note: Media Processing Service concatenates Timestamp and NotifyKey from TaskNotifyConfig as a string and calculates the Sign value through MD5. This value is included in the notification message. Your backend server can verify whether the Sign is correct using the same algorithm, to confirm whether the message is indeed from the Media Processing Service backend.

    Note: This field may return null, indicating that no valid value can be obtained.
    RequestId String The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.
