This platform requires too much processing power to be installed on weak systems. The RK3528A 4-core SBC loads up to 6 when this runs on it. Perhaps a future version of this will have a detector so that when it's installed on a wimpy ARM SBC it will do nothing except save the file; no MediaMTX or Jellyfin. Not important right now.
This platform requires too much processing power to be installed on even half-decent systems. An 8-core Ryzen 5 Mini-PC is incapable of running the entire stack. I have separated the implementation of this to a client and server model. I set up a new VM on my home server that can use nearly all the CPU cores when needed, and set that with a static IP. I created two new roles that call this role with a few different variables, and then the cosmos-server pipeline can be ran with a special server selected to build the default cosmos VHS capture stack. This can probably run on an Intel i9 Mini PC or a similarly beefy Ryzen. It turns out that just the A/V to RSTP job takes a non-trivial amount of compute. Trying to do that and the video encoding at the same time generally takes more than a small CPU can offer. Now there is a VCR server VM that does the capturing of both the preview stream and the capture stream. This also saves it to the network in a spot that the website can automatically see. The client just streams to the server and displays the feed that is running from the server.
This process uses stages of different software to accomplish the goal of making capturing a VHS tape as automatic as possible
