最后更新时间：2024-11-06 16:01:32

1. API Description

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

Initiate an adaptive bitrate streaming processing task, with the following features:

  1. Output HLS and MPEG-DASH adaptive streams based on the specified templates;
  2. DRM options for the adaptive bitrate streaming include no encryption, Widevine, or FairPlay.
  3. The output adaptive bitrate streaming can include multiple audio streams in different languages, with each language sourced from different media files.
  4. The output adaptive stream can also include multiple subtitle streams in different languages.

Notes:

  1. When using opening/closing credits, the video stream in the opening credit must be synchronized with the audio stream; otherwise, it will result in audio and video desynchronization in the output content.
  2. If the output adaptive bitrate streaming needs to include audio from the main media, the FileId of the main media must be specified in the AudioSet parameter.
  3. Subtitles must be added to the main media beforehand, which can be done through the ModifyMediaInfo API interface or the Video Management page in the console.
  4. Support for TESHD transcoding and watermarking is currently not available.

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