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. Valid values: AiReviewResult: content review result. AiRecognitionResult: content recognition result. LiveRecordResult: live streaming recording result. AiQualityControlResult: media live quality control result. AiAnalysisResult: content analysis result. ProcessEof: end of live stream processing.
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 in UNIX Timestamp format. - notifications from media processing default to an expiration time of 10 minutes. if the time specified by the Timestamp value in a message notification has expired, the notification can be deemed invalid, furthermore preventing network replay attacks. - the Timestamp format is decimal UNIX Timestamp, seconds elapsed since midnight (UTC/GMT) on january 1, 1970.
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.
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.
