# Simple FFMPEG scripts I use to convert videos or audios
# The ones with h264_nvenc codec only work with NVidia graphic cards. You also need to install the drives to use them
# The hevc_nvenc codec is pretty fast but the output file size is terrible. So I won't include that in. (Special thanks to Erfan Mojibi)
# The libx265 provides better quality to file size. So we can increase the crf in it (source: https://trac.ffmpeg.org/wiki/Encode/H.265#ConstantRateFactorCRF)
# The tag is provided by @alirezahabib

# Simple convert from webm to mp4. ACC audio codec at 128kb/s. Change 24 to change the quality (higher is worse)

Installing microk8s in an LXC container (i.e.: proxmox)

This is an roundition of https://gist.github.com/acj/3cb5674670e6145fa4f355b3239165c7 which got a bit messy

1. Create a LXC container through the Proxmox web interface (ie.: ubuntu.23-10-lts)
   • untick "unpriviledged" container
   • in memory, set swap to 1024
   • set mem to at least 4096
   • in network, make sure you assign static ip-adress to the container

• create container but don't start it.
