    1. API Description

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

    This API is used to initiate live stream processing tasks. Such tasks may include the following:

    • Intelligent content moderation (detection of pornographic content in images and audio, detection of sensitive information)
    • Intelligent content recognition (face, full text, text keyword, full speech, speech keyword, real-time speech translation, object recognition, game event tracking)
    • Intelligent content analysis (real-time news splitting)
    • Quality control, including recognizing live stream format, checking audio/video content for flickering, blur, low light, overexposure, black bars, white bars, black screen, white screen, noise, pixelation, QR code, etc., and no-reference scoring.
    • Recording

    HTTP callbacks are supported for live stream processing events. Notifications can also be written in real time to and read from a CMQ queue. The output files of processing tasks are saved to the storage you specify.

    A maximum of 100 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.

    ScheduleId No Integer The live scheme ID.
    Note 1:
  • If an output storage (OutputStorage) and directory (OutputDir) are specified for a subtask of the scheme, those output settings will be applied.

    • u200c
  • If an output storage (OutputStorage) and directory (OutputDir) are not specified for a subtask of the scheme, the output parameters specified for ProcessLiveStream (if any) will be applied.

    • Note 2: If TaskNotifyConfig is specified when ProcessLiveStream is called, the specified settings will be applied instead of the default callback settings of the scheme.

    3. Output Parameters

    Parameter Name Type Description
    TaskId String Task ID
    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.
