`helloworld.py`, #476 - https://gitlab.com/whitebox-aero/whitebox/-/issues/476 Implemented recording, but I noticed the FFmpeg processing speed results are VERY inconsistent. Spent a lot of time trying to figure it out and I'm absolutely clueless where to go from here. Sometimes it's real time, sometimes it consistently falls behind a few seconds, sometimes it starts drifting and never gets back up to live speed :|
