1. API Description

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

This API is used to initiate processing tasks for audio-video media in VOD, with features including:

  1. Watermarked video transcoding;
  2. Animated image generating;
  3. Screenshot taking at specified time points;
  4. Sampled screenshot taking;
  5. Capture CSS sprites for videos;
  6. Capture a frame from a video as the cover.
  7. Transcoding to adaptive bitrate streaming with encryption;
  8. Content review (offensive content, unsafe information, inappropriate information). It is not recommended to use this API to initiate it. Audio/Video Moderation (ReviewAudioVideo) or Image Moderation (ReviewImage) is recommended;
  9. Content analysis (tag, category, cover, frame tagging) is not supported for HLS format currently.
  10. Content recognition (video intro and outro, human face, full text, text keyword, full speech, speech keyword, object).

If event notification is used, its type is task flow status change (https://www.tencentcloud.com/document/product/266/9636?from_cn_redirect=1).

A maximum of 200 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.

AiAnalysisTask No AiAnalysisTaskInput

Parameters for the audio and video content analysis task.
AiRecognitionTask No AiRecognitionTaskInput

Audio/video content recognition type task parameter.
TasksPriority No Integer

Priority of the task flow. The higher the value, the higher the priority. The value range is from -10 to 10. If this is not specified, the default value is 0.
TasksNotifyMode No String

Task flow status change notification mode. Valid values are Finish, Change, and None. If this is not specified, the default value is Finish.
SessionContext No String

Source context. This is used to pass user request information. The task status change callback returns the value of this field. The maximum length is 1000 characters.
SessionId No String

Identifier for deduplication. If a request with the same identifier has been sent within the past three days, an error is returned for the current request. The maximum length is 50 characters. If this is not specified or left empty, deduplication is not performed.
ExtInfo No String

Reserved field, used for special purposes.
Url No String

Valid when FileID is empty. Pull the Url to generate a new media asset and a new FileID. Media processing products will be affiliated products of the new media asset.

Note: Storage fees will occur for the new media asset.
OutputAsIndependentMedia No String

The media processing transcoding result is output as standalone media assets. Enabling this option will output the product as standalone media assets and generate a brand new FileID. Currently, only TranscodeTask transcoding task output is supported as standalone media assets.

Enumeration values:

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.
