setPlaybackVolume method

FutureOr<int> setPlaybackVolume(NSInteger volume)

@detail api @author huangshouqin @brief Adjusts the playback volume of the mixed remote audio. 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 ByteRTCReturnStatus{@link #ByteRTCReturnStatus} 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:volume:{@link #ByteRTCEngine#setRemoteAudioPlaybackVolume:volume}/setRemoteRoomAudioPlaybackVolume:{@link #ByteRTCRoom#setRemoteRoomAudioPlaybackVolume}, the volume that the local user hears from user A is the overlay of both settings.

Implementation

FutureOr<int> setPlaybackVolume(NSInteger volume) async {
  return await nativeCall('setPlaybackVolume:', [volume]);
}
