Youtube Dl Helper
youtube-dl is a great tool to download youtube stuff.
Here is some helper script I used.
# download as mp4, playlist also
function youtube-dl-mp4() {
youtube-dl -f "[height <=? 720][tbr>500]" --yes-playlist $1
}
# download as mp3
function youtube-dl-mp3() {
youtube-dl -x --audio-format mp3 --add-metadata $1
}
# download subtitle en
function youtube-dl-sub() {
youtube-dl --write-sub --sub-lang en --skip-download $1
}
