This is a damn sweet bit of code. It will rip and convert to mpg any piece of YouTube video. Now to make it handle batches of requests:)-
#!/bin/bash
bu=’http://youtube.com/get_video.php?’;mkdir -p ~/YouTube;cd ~/YouTube;read -p ‘YouTube url? ‘ ur;read -p ‘Name? ‘ nv
wget ${ur} -O /tmp/y1;uf=${bu}`grep player2.swf /tmp/y1 | cut -d? -f2 | cut -d\’ -f1`;wget ‘${uf}’ -O /tmp/y.flv
ffmpeg -i /tmp/y.flv -ab 56 -ar 22050 -b 500 -s 320×240 ${nv}.mpg;rm /tmp/y.flv; rm /tmp/y1;rm gmon.out; exit”
