Something got disposed after call ConnectAsync

[bpcuong2013]

using (var rtspClient = new RtspClient(new ConnectionParameters(new Uri(RtspUrl)))) { rtspClient.FrameReceived += (sender, rawFrame) => ReceiveFrame(rawFrame); await rtspClient.ConnectAsync(token); await rtspClient.ReceiveAsync(token); }

The exception happens at calling ReceiveAsync method. Please help this one. Thanks!
