setPlaybackVolume method
@detail api
@author huangshouqin
@brief Adjusts the locally playing volume after mixing sounds of all remote users. You can call this API before or during the playback.
@param volume Ratio(%) of playback volume to original volume, in the range 0, 400, with overflow protection.
To ensure the audio quality, we recommend setting the volume to 100.
- 0: mute
- 100: original volume
- 400: Four times the original volume with signal-clipping protection.
@return
- 0: Success.
- < 0 : Fail. See ReturnStatus{@link #ReturnStatus} for more details
@note Suppose a remote user A is always within the range of the target user whose playback volume will be adjusted, if you use both this method and setRemoteAudioPlaybackVolume{@link #RTCEngine#setRemoteAudioPlaybackVolume}/setRemoteRoomAudioPlaybackVolume{@link #RTCRoom#setRemoteRoomAudioPlaybackVolume}, the volume that the local user hears from user A is the overlay of both settings.
Implementation
FutureOr<int> setPlaybackVolume(int volume) async {
return await nativeCall('setPlaybackVolume', [volume]);
}
