1. API Description

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

API description:
This API is used to start an on-cloud recording task. It records the audio and video streams in a room and saves them to the specified cloud storage. You can use this API to record the streams in a room separately, or you can mix the streams first and then record the mixed stream.

You can use this API to perform the following operations:

• Specify the anchors whose streams you want or do not want to record by using the RecordParams parameter
• Specify the storage service you want to save recording files to by using the StorageParams parameter. Currently, you can save recording files to Tencent Cloud VOD or COS.
• Specify transcoding settings for mixed-stream recording, including video resolution, video bitrate, frame rate, and audio quality, by using MixTranscodeParams
• Specify the layout of different videos in mixed-stream recording mode or select an auto-arranged layout template

Key concepts:

• Single-stream recording: Record the audio and video of each subscribed user (UserId) in a room and save the recording files to the storage you specify.
  Mixed-stream recording: Mix the audios and videos of subscribed users (UserId) in a room, record the mixed stream, and save the recording files to the storage you specify. After a recording task ends, you can go to the VOD console (https://console.tencentcloud.com/vod/media) or COS console to view the recording files.

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