UEFI/iPXE booting Raspberry Pi for Flatcar Linux

UEFI/iPXE booting Raspberry Pi for Flatcar Linux

Download and compile the following https://github.com/pftf/RPi4.git. I made the following change to edk2-platforms to always enable 3GB RAM+ as TFTP booting this seems to cause issues with it remembering the options.

4chan’s guide to converting GIF to WebM - https://boards.4chan.org/g/res/41212767

Grab ffmpeg from https://www.ffmpeg.org/download.html

It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.

The most trivial operation would be converting gifs:

ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm
  • -crf values can go from 4 to 63. Lower values mean better quality.
  • -b:v is the maximum allowed bitrate. Higher means better quality.
