Download and Watch YouTube videos from Linux Shell Prompt

by on August 14, 2006 · 26 comments· LAST UPDATED October 21, 2013

in , ,

Publishing your own video on YouTube, or watching other people's videos, is all the rage these days. Why are we talking about YouTube, in a column about the CLI? Because this week we're writing about youtube-dl, a clever little CLI tool that's easy to install and and use to fetch YouTube videos.

Youtube-dl is a Python script, licensed under the "non-copyleft" free software MIT/X11 license. It is not platform-specific; it can run under Linux, Mac OS X, or Windows platforms so long as a recent -- 2.4 or later -- version of Python is installed. It is a small command-line program to download videos from YouTube.com and a few more sites. It requires the Python interpreter (2.6, 2.7, or 3.3+), and it is not platform specific. It should work in your Unix box, in Windows or in Mac OS X. It is released to the public domain, which means you can modify it, redistribute it or use it however you like.

Update: Check out this bash script - it does same thing without using python.

Great information, thanks very much!

You might try this for Zsh (maybe modern Bournes?):

ytdl () {
video_id=${1#http://*youtube.com/watch?v=}
video_id=${video_id#http://*youtube.com/v/}
video_id=${video_id%&*}
player_line=`ftp -o - "http://www.youtube.com/watch?v=$video_id"|grep /player2.swf`
base_getter_url=http://youtube.com/get_video.php?
url=${player_line/*player2.swf\?/$base_getter_url}
url=${url%%\"*}
ftp -o $video_id.flv "$url"
ffmpeg -i $video_id.flv -ab 56 -ar 22050 -b 500 -s 320x240 $video_id.mpg
echo
echo mplayer $video_id.mpg
}

If you have an ftp with HTTP support.

The ZSH code has a problem:

Here’s the bash script, made more solid. I fixed the ffmpeg call (it doesn’t like making 15fps mpeg files), and kept the flv at the end.

If you want to use the flv from your own apache server you’ll need to add

video/x-flv flv

to /etc/mime.types and restart apache, then go and get flash_flv player from http://www.jeroenwijering.com/upload/flash_flv_player.zip

unpack it, put flvplayer.swf and flvplayer.html on your site with the .flv, and modify flvplayer.html appropriately

#!/bin/bash
bu=”http://youtube.com/get_video.php?”
tmp=`mktemp`
touch ${tmp}.flv
read -p “YouTube url? ” ur
wget ${ur} -O ${tmp}
uf=${bu}`grep player2.swf ${tmp} | cut -d? -f2 | cut -d\” -f1`
nv=`cat ${tmp} | grep ‘h1 id=”video_title”‘ | cut -d “>” -f 2 | cut -d “

nv=`cat ${tmp} | grep ‘h1 id=”video_title”‘ | cut -d “>” -f 2 | cut -d “lt” -f 1`

*** i can’t post a less than symbol, so change the lt in that command to a less than symbol

echo “Title ${nv}”
wget “${uf}” -O ${tmp}.flv
ffmpeg -i ${tmp}.flv -r 30 -ab 56 -ar 22050 -b 1500k -s 320×240 “${nv}.mpg”
mv ${tmp}.flv “${nv}.flv”
rm ${tmp}
exit

There’s now a software tool to allow linux users to download youtube videos to a preferred directory, in a variety of formats (mpeg, wmv, mp4, flv, avi), specifying the resolution… all in a GTK theme’d graphical tool.

Check it here:

Feedback most appreciated, via the forums or by email.

There’s a new script for linux to search and watch youtube’s video on linux shell, called YouShell.

I think you should update the article, the project has apparently moved to github:
