NixOS image availablee
#1
Hi All!

Daniel Fullmer has put a link to his github repository for the pinecube on the the pinecube wiki. I flashed the provided NixOS image to SD card and booted the pinecube. It took a bit to boot, but after a short while I was able to ssh to the pinecube. Following the instructions in his repository, I was able to record from the camera to a local file first try! Well done, Daniel!

Hi there

I downloaded the 2020-11-07 NixOS image for a new Pinecube, and seem to have an issue recording from CSI camera. 
Using the README's Additional Notes, the first `media-ctl` command is accepted, but the second `ffmpeg` produces a couple of warnings and fatal "Connection refused" messages. 
The console output:


Code:

Daniel's ffmpeg command tries to stream to a rtmp server. Daniel's rtmp server listens at IP 192.168.1.89.
You can either setup a rtmp server (there is a rtmp module for nginx available), or, for testing purposes, dump the video stream to a local file.
In the this case, you  replace "rtmp://192.168.1.200/live/pinecube" with "mycamera.avi" or something similar.

Thank you for the clarification and the alternate destination.  
(There's a lot I need to learn about video and "RTMP server".)
Writing to a local file was the simplest & fastest way for me to demonstrate that the camera works.
