Help with C# TCP connection to Hyperdeck

PostTue May 07, 2019 11:24 pm

So, I've been trying to get a TCP/IP client connection to our Hyperdeck Pro working but so far I have not been able to get it to work. It's funny because I was able to get a TCP connection to our VideoHub 20x20 working with no problem with this code but the same code does not work with the Hyperdeck. When I run it nothing happens. Any ideas anyone? Code below:

Code: Select all

...
...
...
using System.Net.Sockets;


        private void button29_Click(object sender, EventArgs e)
        {           
            hyperdeck_cmd("play");
        }

        private void hyperdeck_cmd(string cmdtxt)
        {
           // TCP connection vars...
           private TcpClient hdeckClient;
           string hdeckserver = "10.x.x.x";
           int hdeckPort = 9993;
   
            //New client object...
            hdeckClient = new TcpClient();
            hdeckClient.Connect(hdeckserver, hdeckPort);

             //...append carriage return and newline
            cmdtxt = cmdtxt + "\r\n";

             //...send stream
            int bytecount = System.Text.Encoding.ASCII.GetByteCount(cmdtxt);
            byte[] sendData = new byte[bytecount];
            sendData = System.Text.Encoding.ASCII.GetBytes(cmdtxt);
            NetworkStream stream = hdeckClient.GetStream();
            stream.Write(sendData, 0, sendData.Length);

            //...cleanup
            stream.Close();
            hdeckClient.Close();
        }

Hi Oscar,

I have run through your code with hyperdeck_cmd method unmodified (apart from setting IP address) and it works ok. The likely reasons for this issue are:
  • You have not enabled remote control
  • You have another client connected
If it's the latter, the HyperDeck Studio Pro limits 1 client connection and will remotely disconnect any further connections. The issue is that TcpClient does not automatically detect the disconnection. A potential workaround is after calling stream = hdeckClient.GetStream(), call stream.Read to dump out the header information received on connection:
Code: Select all
500 connection info:
protocol version: 1.8
model: HyperDeck Studio Pro
If the NetworkStream.Read() returns 0, then the connection has been remotely disconnected.

Regards
Cameron

Cameron thanks for the prompt response.

Yeah it's returning 0 with the code below. As far as I can tell there is no other client connecting to the Hyperdeck. Question: Does the ATEM Software control use the TcpClient to control the Hyperdeck? Anyway to retrieve the IP or client name of the connected TcpClient...?

Code: Select all

using System.Net.Sockets;


        private void button29_Click(object sender, EventArgs e)
        {           
            hyperdeck_cmd("play");
        }

        private void hyperdeck_cmd(string cmdtxt)
        {
           // TCP connection vars...
           private TcpClient hdeckClient;
           string hdeckserver = "10.x.x.x";
           int hdeckPort = 9993;
   
            //New client object...
            hdeckClient = new TcpClient();
            hdeckClient.Connect(hdeckserver, hdeckPort);

             //...append carriage return and newline
            cmdtxt = cmdtxt + "\r\n";

             //...send stream
            int bytecount = System.Text.Encoding.ASCII.GetByteCount(cmdtxt);
            byte[] sendData = new byte[bytecount];
            sendData = System.Text.Encoding.ASCII.GetBytes(cmdtxt);
            NetworkStream stream = hdeckClient.GetStream();

            //...is it dropped?
            int ntdata = stream.Read(sendData, 0, sendData.Length);
            string msg = ntdata.ToString();
            MessageBox.Show(msg, "stream dump");

            stream.Write(sendData, 0, sendData.Length);

            //...cleanup
            stream.Close();
            hdeckClient.Close();
        }

UPDATE . . .

OK I got it working but I had to remove the Hyperdeck from the ATEM's Hyperdeck configuration panel. I assume the ATEM software uses the TcpClient to control the hyperdeck...

Offcoarse it does. That is the normal way that the Atem connects with the Hyperdeck. And as soon the BMD software is open / ip set for a hyperdeck in the Atem hardware. This will always take presence as soon as the hardware boots.

I really think it should have multiple client capability so that at least I could connect to it remotely without having to remove it from the ATEM software.

Would be nice.. But all depends on how it is set up in the firmware. Our fiber muxes also allow 1 connection at a time due too a limit on the hardware chip. :?
