How to build a TCP client in LabVIEW to receive webcam video from Python?

[Azer Ader]

Hello,

I have a Python TCP server that streams webcam video frames as JPEG over the network. Now I want to build a LabVIEW client that can:

• Connect to the Python server

• Read the first 4 bytes (frame length)

• Receive the JPEG frame data

• Display the image on the LabVIEW Front Panel

Note: I do not have NI Vision Toolkit, so I need a solution using .NET (MemoryStream + Image.FromStream) or any other method to display the image.

Can someone share a simple example VI or block diagram to achieve this?

Thanks 🙏tcp_video_server.pywebcam_tcp_client.py

@Azer Ader, you do not need .NET stream. Just use the native TCP socket. I recommend you read all incoming bytes and pass them down to a decoding loop. 
Here's an un-tested example code. You'll need to unflatten the bytes to image base on your image format.
