Agora Cloud Recording is an add-on service to record and save voice calls, video calls, and interactive broadcasts on your cloud storage. Compared with Agora On-premise Recording, Agora Cloud Recording is more efficient and convenient as it does not require deploying Linux servers.


Agora Cloud Recording is compatible with the following SDKs:

  • Agora Native SDK v1.7.0 or later.
  • Agora Web SDK v1.12 or later.


v1.3.0 is released on October 8, 2019.

New features

1. Individual recording

The RESTful API adds individual recording mode, which supports recording the audio and video of each UID separately. See Individual Recording for details. Meanwhile, Agora provides the Audio & Video File Merging script, which you can use to merge the audio and video files generated in individual mode. See Merge Audio and Video Files for details.

2. Record specified UIDs

The RESTful API adds the subscribeAudioUids and subscribeVideoUids parameters, which allow you to record only specified UIDs.

3. Customize the directory of the recorded files

The RESTful API adds the fileNamePrefix parameter, which allows you to specify the directory where you want to store the recorded files in the third-party cloud storage.

4. Timestamp when the stream state changes

The RESTful API callback service adds the recorder_audio_stream_state_changed and recorder_video_stream_state_changed events to report the time when the state of the audio or video stream changes, as well as the corresponding UID.

5. Format Converter script

Agora provides the Format Converter script, which you can use to convert between multiple file formats, such as TS, MP3, and MP4. See Convert File Format for details.

6. Synchronized playback

You can achieve synchronized playback between the recorded files and other stream files, such as online whiteboards, courseware, and messages, by using the timestamp when the recording starts. You can get the timestamp by using the RESTful API callback service, or by parsing the M3U8 file. See Synchronized Playback for details.


When an error occurs, you receive the error message in the HTTP response body, instead of just the error code. See Agora Cloud Recording RESTful API for detailed information about the error codes.

Fixed issue

When uploading fails after you use the wrong bucket and key values of the third-party cloud storage, Agora Cloud Recording returns an error instead of uploading the recorded files to Agora Cloud Backup.


v1.2.0 is released on July 22, 2019.

New features

Customized video layout

The RESTful API adds a customized layout for the recording video. See Set Video Layout for details.

You can set the mixedVideoLayout parameter as 3 and set the regions for each user in the layoutConfig parameter when starting a recording.

You can update the layout anytime during the recording by the updateLayout method.

Customized background color

The RESTful API adds the backgroundColor parameter to support customized background colors for the video layout.


To get the accurate starting time of a recording, the RESTful API provides the Unix timestamp of when the first slicing starts in the response of the query method. The RESTful API callback service adds the recorder_slice_start event to report the time when the first slicing starts and the time when the last recording fails.


Optimizes the verification of whether resourceId corresponds with uid and cname when calling the RESTful API.

Fixed issue

Fixed minor issues in the default video layout (floating layout).
