rofi ffmpeg screenrecorder prototype

README.md

rofi ffmpeg screenrecorder

This script provides a mode for rofi which gives you the commands to create screenshots and videos from your favorite terminal windows. (Other windows are also no problem, but who cares about gui windows.)

TODO

• file=$HOME/Videos/screencast*(om[1]) is a bit hacky
• cleanup code (this is a prototype)
• right now the script will try to upload every new video to streamable
• a indicator somewhere that a recording is running
• make configuration editable via rofi: eg streamable upload, ffmpeg parameters
