# Jeff Geerling's super-rudimentary fan controller script for the CM4.
#
# Use:
#   1. Download this script to a path like `/opt/cm4-fan.sh`
#   2. Run it with: `nohup bash /opt/cm4-fan.sh`
#   3. Profit!

# Builds arm64 debian packages from the CURRENT rpi firmware repository kernel which is installed by:

# This runs on an arm64 host with arm64 compilation tools...

# This will NOT work in Raspbian unless you have an arm64 compilation

Considerations to take when live streaming:

The following best practice observations apply when using a hardware-based encoder for live streaming to any platform:

1. Set the buffer size (-bufsize:v) equal to the target bitrate (-b:v). You want to ensure that you're encoding in CBR mode.

2. Set up the encoders as shown:
