OctoPrint VS MJPG-streamer

The cheapest way is to use OctoPrint. Octoprint itself is free, and although it's often run on a Raspberry Pi, it can be installed on many things, such as an old laptop runing Linux or even Windows, or a small single-board computer. OctoPrint would connect to the printer using a USB cable, and you'd send the slicer output to Octoprint over your WiFi.

- Two LibreELEC (https://libreelec.tv/) mediaplayers in house (yes, one is not enough in my big family).

- One for hosting low usage applications at home network (Unifi controller and some more).

- Octoprint (https://octoprint.org) connected to the 3d-printer.

- One on my desk for hardware hacking – mostly as just a PC with GPIO.

- Some Raspberry Pi Zeros as security cameras.

Really quite easy, especially if you have ever dealt with a raspberry pi before. Once installed & set up, you manage everything over a web interface. I even added a webcam to it in order to see what's going on. Check out https://octoprint.org/

For other devices it can be harder, there are guides for installing on Linux on the octoprint website (I use an old laptop running Linux Mint). If using an old Android phone look for Octo4A.

I’d just get Octoprint setup and a camera for it

mjpg-streamer uses MMAL to access the Raspberry Pi Camera data, but that's not implemented on ARM 64-bit Linux.

cd ~ sudo apt-get install cmake libjpeg62-turbo-dev:armhf libjpeg62-turbo-dev imagemagick ffmpeg libv4l-dev cmake git clone https://github.com/jacksonliam/mjpg-streamer.git cd mjpg-streamer/mjpg-streamer-experimental export LD_LIBRARY_PATH=. make sudo make install

I think I was able to solve my own issue. I'm now using https://github.com/jacksonliam/mjpg-streamer to start a stream. It creates a minimal web interface at http://pi-address:8080/, and the path /?action=stream can be accessed from MotionEye.

I need to stream all three of them to a Windows computer, so the maximum bandwidth is about 100mbit. I have tried "motion", but the performance is abysmal. I get not more that one frame per second and the latency is 3s. I used https://github.com/jacksonliam/mjpg-streamer with one camera. Its super fluid with a latency of maybe 200ms, and full 30fps. But the stream takes 60mbit/s bandwidth so it is impossible to use all three cameras. I tried changing the jpg quality but mjpg-streamer crashes.

Thanks for your interest! I will opensource this project soon, but in case you want to start off now, here's some resources I used: - MJPG-Streamer https://github.com/jacksonliam/mjpg-streamer - .NET 6, targeting Linux (tutorial:) - dotnet package on linux - My custom designed case (beta!): Bottom part - Top part

Have you looked into mjpg-streamer (or other forks, this was the first Google result)
