This page shows how to record a call by calling API methods. You can also record calls by using the command line, see Record by Command Line. The command line and API methods implement the same recording functions.
The Agora On-Premise Recording SDK joins a channel as a dummy client. It needs to join the same channel and use the same App ID and channel profile as the Agora Native/Web SDK.
Ensure that you integrate the SDK before proceeding.
Call the createAgoraRecordingEngine method to create a recording instance and connect it with your app. You can create multiple instances to record simultaneously.
After creating a recording instance, call the joinChannel method to join the channel and start recording. In this method, fill in the following parameters:
channelKey: (Optional) The token used in the channel to be recorded. If the channel uses a token, ensure that you pass a token in this parameter. See Secure authentication.
channelId: (Mandatory) The name of the channel to be recorded.
uid: (Mandatory) User ID. A 32-bit unsigned integer ranging from 1 to (232-1) that is unique in a channel. If the
uidis set as 0, the SDK assigns a uid.
config: (Optional) The recording configuration. See
After joining the channel, the SDK starts recording when detecting other users in the channel.
If you set
RecordingConfig, you need to call the
startService method to start recording manually. During the recording, you can call the
stopService method to pause the recording.
Ensure that you call the
stopServicemethods only after joining a channel.
After joining a channel, you can call the getProperties method to get the directory of the recording files.
You can also get the directory in the onUserJoined callback when a remote user joins the channel.
Call the leaveChannel method to stop recording and leave the channel.
To start recording again after calling this method, create another instance.
If the leaveChannel method is not called, the SDK automatically leaves the channel and stops recording when no user is in the channel for more than 300 seconds (you can set this interval by the
idelLimitSec parameter in
RecordingConfig by default.
Call the release method to destroy the recording instance and release all recording resources. After releasing the resources, you must create a new instance to use On-Premise Recording again.
Do not implement the
releasemethod in the callback thread.
