Audio

The ZMVideoSDKAudioHelper provides methods to manage a user's audio. Before implementing audio controls, you must first check if the user is connected to audio or not by getting the audio type of the user. Start audio with StartAudio().

ZMVideoSDKUser myself = session.GetMySelf();
ZMVideoSDKAudioHelper audioHelper = ZMVideoSDK.Instance.GetAudioHelper();
ZMVideoSDKAudioStatus audioStatus = myself.GetAudioStatus();
if (audioStatus.audioType == ZMVideoSDKAudioType.ZMVideoSDKAudioType_None)
{
  audioHelper.StartAudio(result =>{});
} else {
  // The user is already connected to audio.
}

Once connected, you can mute a user's audio by calling muteAudio with the associated ZoomVideoSDKUser object.

audioHelper.UnMuteAudio(myself, result => {});

You can also unmute a user's audio can also in a similar manner.

audioHelper.MuteAudio(myself, result =>{});

To disconnect from audio, use the stopAudio method.

audioHelper.StopVideo(result =>{});

Callbacks

The following are examples of some audio callbacks in the ZMVideoSDKDelegate implementation class.

Get notified when a user's audio status has changed

public void onUserAudioStatusChanged(ZMVideoSDKAudioHelper audioHelper, List<ZMVideoSDKUser> userArray)
{
  foreach (ZMVideoSDKUser user in userArray)
  {
    bool isMuted = user.GetAudioStatus().isMuted;
  }
}

Get notified when active audio changes

public void onUserActiveAudioChanged(ZMVideoSDKAudioHelper audioHelper, List<ZMVideoSDKUser> userArray)
{
  foreach (ZMVideoSDKUser user in userArray)
  {
    bool isMuted = user.GetAudioStatus().isMuted;
  }
}

Subscribe to users' audio raw data

ZMVideoSDKAudioHelper audioHelper = ZMVideoSDK.Instance.GetAudioHelper();
audioHelper.Subscribe(res =>
{
  if (res == ZMVideoSDKErrors.ZMVideoSDKErrors_Success)
  {
    enableRawAudio = true;
  }
  Debug.Log("onUserAudioStatusChanged result = " + res);
});

Get notified when mixed audio raw data is received

public void onMixedAudioRawDataReceived(ZMVideoSDKAudioRawData audioRawData)
{
  // See raw data documentation for more information
}

Get notified when one-way audio raw data is received

public void onOneWayAudioRawDataReceived(ZMVideoSDKAudioRawData audioRawData, ZMVideoSDKUser user)
{
  // See raw data documentation for more information
}
