I would like to send TCP commands to a BlackMagic Video hub matrix from a vMix script

this should be just a telnet command to port 9990

I also want to be able to conteol Barco E2 which is also telnet on a custom port


I think i will end up instead doing it via a DLL that i load as a title as i then have the full vb blend enviroment available!

In case anyone else wants to send a tcp message to another client using vMix scripting, I just figured it out...

Create a new script and add the following code. Be sure to change your destination IP address, port and the message you want to send

Code:

Dim clientIP as String = "XX.XX.XX.XXX"
Dim clientPort as String = "XXXXX" 
Dim message as String = "YOURMESSAGE"

Dim client As New System.Net.Sockets.TcpClient(clientIP, clientPort)
client.SendTimeout = 1000
client.ReceiveTimeout = 1000

' Translate the passed message into ASCII and store it as a Byte array.
Dim data As [Byte]() = System.Text.Encoding.ASCII.GetBytes(message)

' Get a client stream for reading and writing.
Dim stream As System.Net.Sockets.NetworkStream = client.GetStream()

' Send the message to the connected TcpServer. 
stream.Write(data, 0, data.Length)

' Receive the TcpServer.response.
' Buffer to store the response bytes.
data = New [Byte](256) {}

If stream.CanRead Then
    Dim myReadBuffer(1024) As Byte
    Dim myCompleteMessage As System.Text.StringBuilder = New System.Text.StringBuilder
    Dim numberOfBytesRead As Integer = 0

    ' Incoming message may be larger than the buffer size.
    Do
        Try
            Threading.Thread.Sleep(100)
            numberOfBytesRead = stream.Read(myReadBuffer, 0, myReadBuffer.Length)
            myCompleteMessage.AppendFormat("{0}", System.Text.Encoding.ASCII.GetString(myReadBuffer, 0, numberOfBytesRead))
        Catch ex As Exception
            stream.Close()
            client.Close()
            Exit Sub
        End Try
    Loop While stream.DataAvailable

    ' Close everything.
    stream.Close()
    client.Close()
    Exit Sub
Else
    Exit Sub
End If


Smudge . . . you were close. Since there is no "Imports", you just have to use your classes explicitly.

So for example, to set the output on a videohub:

Code:

Dim clientIP as String = "XX.XX.XX.XXX"
Dim clientPort as String = "9990" 
Dim input as String = "1"
Dim output as String = "7"
Dim message as String = "VIDEO OUTPUT ROUTING:" & Environment.NewLine & output & " " & input & Environment.NewLine & Environment.NewLine
...

I'm trying to create a script using the code mentioned in this thread.

I'm trying to send Telnet commands to a Vaddio Roboshot20 PTZ camera. I have successfully sent commands from command prompt and PowerShell, but I'm not having success in vMix.
I think that my issue might be that there is a username and password that you have to enter before you can throw commands at the camera.


This is what I've tried so far.

Quote:
Dim clientIP as String = "192.168.3.101"
Dim clientPort as String = "23"
Dim message as String = "admin"
message = "password"
message = "camera preset recall 1"

...


I'm not much of a coder so my apologies for my noobiness.

Hi jthrup,

Did you find some solutions for your usecase?
I've the same situation as you. I am looking to send telnet commands from vmix. I don't have to fill username or password. Only a command like "page 1000: read" with an ip and a port.

It works fine with powershell. But, the script above doesn't work for me either.
