This script builds and install FFmpeg (n4.3.2) and OBS Studio (26.1.2) on a Raspberry Pi 4. Derives and copypasta from different scripts that I have found but unfortunately they did not run successfully. This script may not work tomorrow or next week, so feel free to open a ticket issue to let me know.
Before running the script you must upgrade the currently Raspberry Pi OS Buster version to the not yet released Bullseye. This tutorial explains the basic steps of how to do it. If you found issues during the upgrade phase check it out the troubleshooting section of that step by step tutorial: Manually upgrade Debian from Buster to Bullseye.
No questions at this moment.
