I would not suggest using cloudflare containers for ffmpeg. Feels like it is the nost expensive product they have. Queue to aws spot instances or just have dedicated hetzner machine
Has anyone tried it? I tried to set up a simple livestream a year ago and it was far from simple. It felt very hackish and documentation was lacking. I guess putting more time I would succeed in the end. Did ask if I could hire the developers to do setup for me, but didn't really get anywhere with it :/
