I'm writing a Rust digital signage player very heavily influenced by info-beamer, with a focus more on local intranet control: https://github.com/superlou/signrs. You develop a signage application in JavaScript with drawing functions, and the player runs it cross-platform (including Raspberry Pi), and provides a web server for remote control.

I am trying to port a digital signage application I built on info-beamer to Godot. The application is expected to run full-screen on a set of Raspberry Pi 3Bs (at least until Pi 4s are back in stock), preferably with 1600x900 px resolution or better since the application is mostly drawing text.

I would suggest you check out info-beamer.com and trueomni.com . I am using info-beamer on several displays in commercial situations and it has worked well. I haven't tried rotating to an angle but you should be able to map the screens as if they are level and play the content across them all. Source: over 1 year ago

You might also try out info-beamer (full disclosure: operated by my company) if you have 30 minutes of spare time. Unlike pisignage and yodeck, it's not based on Raspberry Pi OS and implements some reliability features they cannot easily add like: Complete OS image verified every boot to detect any corruption, OS always read-only even during OS upgrades thanks to A/B booting, 100% power loss safe and highly...

My most recommended method for beginners has always been PD (https://puredata.info/) combined with The Theory and Technique of Electronic Music: (https://msp.ucsd.edu/techniques/latest/book.pdf) and this book (https://mitpress.mit.edu/9780262014410/designing-sound/). Eli's tutorials on SuperCollider are also very helpful: https://www.youtube.com/@elifieldsteel Of course, my project Glicol can also be helpful for... - Source: Hacker News / 9 days ago

Tools like Ossia Score, Chataigne and PureData (pd) can also help a ton in building interactive art and triggering other A/V software. Source: about 1 year ago

WebPd is a highly modular compiler for audio programming language Pure Data allowing to run .pd patches on web pages. It converts the audio graph and processing objects from a patch into plain human-readable JavaScript or WebAssembly which can then be integrated directly into any web application.

You might also be interested in the very different Pure Data (http://puredata.info/) environment, which is also free and open-source. It uses a visual programming approach, which many people like but if you are already a programmer it might seem inconvenient in comparison. Source: about 1 year ago
