EspressoBin v5 Router

I use my EspressoBin as a router and it does a great job of it. It handles DHCP, DNS and firewalling for my network across multiple VLANs. Initially I tried using Arch Linux and Armbian, which had support for the board at the time, but I had various issues with those and eventually whipped up my own Devuan image. It has been quite stable for me across several releases (ascii->beowulf->chimaera). I do however, still use the kernel package from Armbian's repo.

My plan is to leave some notes here on some various things I've done with the EspressoBin since setting it up as my router here at work.

• Adding an RTC module
• IPv6 - Work in Progress

Streaming to the new YouTube Studio with ffmpeg and nginx-rtmp

I've been successfully streaming to YouTube from a Teradek Vidiu Pro hardware encoder, but wanted to play with streaming to both YouTube and Facebook at the same time. I also wanted to be able to stream pre-recorded videos as if they were live. To accomplish this, I turned to nginx-rtmp and ffmpeg. The only problem was, it didn't work. There are plenty of tutorials out there for setting up nginx-rtmp and for using ffmpeg to send rtmp streams, but no matter what I tried I couldn't get the stream to start on YouTube. I'd start streaming to YouTube, and I could see in the Live Dashboard it would change from No data to Excellent connection, but that was it. The Go Live button was disabled and there was nothing I could do about it. I suspect this is also why I was unable to get castr.io to stream to YouTube as well.

However, after much trial and error, I found that if I switched from Live Control Room to Stream Now Classic, I was
