A sample socket programming in python using low level networking interface module socket.
Inside 'cam_streaming' directory one could the variant of client and server script which reads the cam data and on client side and send it to server. Then server could show up to two stream for received cam images. Among the two stream, for one stream latency could be added. Check config file inside cam_streaming directory to set the configuration.
-
Create conda environment with required dependencies by running:
conda env create --name socket_prog --file conda_env_export.yml
-
Run server first and then client.
-
To close connection, give keyboard interrupt to client, server will close automatically.
You will find follwing on top of vanilla implementation you find in any first tutorial link you get from googling:
- Allowing communication with trusted client only, check using first received message from client as key message
- Multithreading to handle multiple clients
- Use of pickel to serialize any type of data
- Handling of variable length data by passing payload size along with payload
- Passing data identifier with payload as additional information to take specific action accordingly (eg. if data identifier is image then save payload as image)
- Using keyboard interrupt to close client and server cleanly
- Program is written in python 3.7.4
Feel free to request more feature you would like, i wil try to add it when i get time
