📹video_server

Python code for a Raspberry Pi http mjpeg video server.

Main characteristics:

1. TCP based communication with multiple clients.
2. Real time video manipulation (fps, exposure time, iso, etc).
3. Simultaneous high-res and low-res capture.
4. Simultaneous capture and manipulation.
5. Infrared capture.

💻Requirements

Hardware

• This was running on a overclocked (cpu and gpu) 8GB Raspberry Pi 4
• We used the Raspberry Pi HQ Camera with the infrared filter removed.
• The server was communicating to a local windows machine via TCP. Three machines in total communicated via a network switch.
• 1 GigE was enough across all machines.

Software

• cifs-utils and samba client for shared folder system
• opencv-python
• picamera2

🖱️ Use

As mentioned, this server is part of a bigger (multi-system) project (all repositories belonging to this project have expS as a prefix). It constitutes the video server that allows the user to (from a menu controlled with a glove) record, play and manipulate real time video.

The user can:

1. Turn on/off a real time video stream that is accessible via http on any local network machine.
2. Manipulate that video's characteristics (fps, exposure time, iso) in real time.
3. Start/stop video capture (to storage) at will.
4. The captured video can be accessed while recording to disk, for almost zero delay video editing.
5. The captured video can be recorded on any shared folder of any machine on the local network.

• I am sharing this here because some concepts might interest some people. The code is not made to run first time. All the system needs to be setup, with all the credentials and the right hardware.
