Capturing and Streaming TV Screen Content as a Daemon Service

Smart TV
1

I am developing a web application called “SamyGrabber” designed to capture and stream the screen content of Samsung Smart TVs. The main features of the application include:

  • Capturing and streaming TV screen content in real-time.
  • Synchronizing LED lights with TV visuals using Hyperion.
  • Controlling the app via a web interface and remote control.
  • Operating in the background as a daemon for continuous functionality.

Currently, I’m able to capture and send a section of the screen content to Hyperion. However, I’m facing challenges in capturing the entire screen and ensuring the app runs as a background service (daemon).

I need guidance on the following:

  1. How to capture the entire screen content of the TV.
  2. How to implement the app as a daemon to ensure continuous screen capture and streaming, even when the app is running in the background.

Any assistance or guidance on how to achieve these functionalities would be greatly appreciated.

Thanks

What a bummer… I also just send a request via the 1:1 Q&A section, if I get a good response I’ll share it here.
As far as I can see, I can’t send you a PM, but maybe I’m missing something? I’m new to this platform and if this is possible, can you tell me how I send a PM?
You said that you were able to capture a part of the screen. Were you able to capture only parts of your own app or also other apps/the TV?

Spoiler alert: they will say: “here are some useful APIs” and they are not.

No, I tried with everything but I wasnt able to capture the screen outside the web app.
You can chat me on telegram, search me by @GonzaCass
