Review comment:
Yes, it's tricky and also fragile :)
Why not increase ref count when it's needed?
```
if (notifyReceivedBuffer != null && inputGate.bufferReceivedListener !=
null) {
inputGate.bufferReceivedListener.notifyBufferReceived(
notifyReceivedBuffer.retainBuffer(), <-- here
channelInfo);
}
```
