Linux - jak stahovat videa z youtube

Chtěla bych si stáhnout z youtube nějaká videa na mém linux ubuntu. jde to vůbec nějak?

ODPOVĚĎ

Ano, není to nic těžkého stáhni si youtube-dl - sudo apt-get install youtube-dl . Pak zadej url z youtube, co chceš stáhnout youtube-dl -F http://youtube.com/link - to ti vypíše dostupné formáty. Ty pak vybereš ten co se ti nejvíc líbí třeba youtube-dl -f 18 http://youtube.com/link a video se ti tím stáhne. Kdybys chtěl mp3 z youtube videa, tak použij youtube-dl --extract-audio --audio-format mp3 http://youtube.com/link

ODPOVĚĎ
