SHADERed Installation for Ubuntu

$ [ ! -d /opt/SHADERed ] || sudo rm -rf /opt/SHADERed
$ sudo apt-get install -y libsfml-dev
$ cd /tmp
$ zip_url="$(curl https://api.github.com/repos/dfranx/SHADERed/releases | jq '.[0].assets[] | select(.name | contains("Linux.zip")) | .browser_download_url' -r)"
$ curl -JL "${zip_url}" -o shadered-linux.zip
$ unzip shadered-linux.zip
$ sudo mv SHADERed /opt/SHADERed

We can't do this with youtube-dl alone, we can pair this with ffmpeg to acomplish this task though. We use youtube-dl and ffmpeg to resolve the URL of the video, and then tell ffmpeg to download the range itself.

So to take a sound byte from this podcast and use it to create my ringtone:

$ audio_url="$(youtube-dl --audio-format mp3 --get-url https://youtu.be/s8tJ-R28HX8 | grep mime=audio | head -n 1)"
$ ffmpeg -ss 02:00:02.10 -i "${audio_url}" -t 00:00:12 -c:a mp3 paul-ringtone.mp3
