youtube-dl script

#!/bin/bash
echo "This is a simple (and low quality) script to download all videos from"
echo youtube playlist and convert them to mp3. it use youtube-dl and ffmpeg
echo binaries to achieve this. To use this you will need ID of a YouTube
echo playlist and internet connection to download videos. This script will
echo need autnentication via sudo once for installing or updating ffmpeg
echo in the following steps it will ask for some info like playlisy id.
echo working directory, prefered video formats etc. There is no default so
echo you must answer all questions in the following steps!
echo This script for now works only with ubuntu based Operating system!
echo
echo ------------------------------------------------------------------------
echo
echo Enter the playlist ID
echo If your playlist url is http://www.youtube.com/playlist?list=PLpsNuha2_QyaGF2AX813SJP9Tqj4rjxls
echo then playlist id is PLpsNuha2_QyaGF2AX813SJP9Tqj4rjxls
echo example playlist id: PLpsNuha2_QyaGF2AX813SJP9Tqj4rjxls
read PLAYLIST
PLAYLISTURL=https://www.youtube.com/view_play_list?p=$PLAYLIST
echo Ok, Playlist is $PLAYLISTURL
echo Enter directory to use
echo you can use relative directory like Videos or absulute path like /home/user/youtube-videos
echo you do not need to create the directory manually.
echo Script will create the folder automatically if not exist.
echo IF YOU ARE USING EXISTING FOLDER IS SHOULD BE EMPTY!
echo example relative directory: Videos
echo example relative directory: youtube/Videos
echo example absulute path: /home/user/youtube/Videos
read DIRT
echo Ok, directory is $DIRT
echo Checking if your prefered directory exist and creating automatically if not exist
mkdir -p $DIRT
echo Changing to working directory
cd $DIRT
echo please select your prefered video quality
echo higher quality will result higher file size and take longer to download
echo For your referance here is some common code for quality
echo you can see all supported codes at https://en.wikipedia.org/wiki/YouTube#Quality_and_codecs
echo
echo "144p/3gp:  17 (Very Low Quality)"
echo "240p/3gp:  36 (Low Quality)"
echo "240p/flv:  5  (Low Quality)"
echo "360p/mp4:  18 (Medium Quality) - Prefered For most videos"
echo "480p/flv:  35 (High Quality)"
echo "720p/mp4:  22 (High Quality HD resulation) - Prefered for Screen presentation, video tutorials"
echo "1080p/mp4: 37 (Very High Quality FullHD resulation)"
echo
echo Input the appropriate code below
echo for best results use mp4 formats
echo you can prefer  two or three types at once.
echo If first one is not avaulable next one will be used and so on
echo "just make sure you are using same container/file format (mp4 or flv)"
echo example of single code 18
echo example of multiple preferance: 37/22/18
read Q
echo Please input file format of that code
echo Your file format must match with quality code.
echo for instance, if you chose code 18 your file time is mp4
echo acceptable values mp4 flv 3gp
echo example input: mp4
read T
echo "Ok, your selected quality code(s): $Q and file format: $T"
echo please set a bitrate for converted audio/mp3 files
echo higher bitrate will result better quality and larger file size
echo you should input bitrate as a number and k in the end
echo here are some most common example
echo 24k 32k 64k 96k 128k 192k 256k
echo only one is allowed
echo example input 128k
read AQ
echo ok, your selected audio bitrate for converted mp3 is $AQ
echo this script needs youtube-dl and ffmpeg binaries to work.
echo checking if they are installed
echo if they are not installed script will try to install them automatically
echo this will also upgrade outdated binary if needed
echo you may need to authenticate
echo this may take some time
# latest version of youtube-dl is important and generally
# not available in distributions repository. So this check
# will add addiional ppa for it if needed.
if [ "$(which youtube-dl)" = '' ]; then
echo youtube-dl binary not found. To install latest version of
echo youtube-dl we will add webupd8 ppa
echo please hit enter when asked to add this ppa and continue
sudo add-apt-repository ppa:nilarimogard/webupd8
fi
# Even if system has youtube-dl and ffmpeg installed this
# process will make sure they are latest version and/or
# update them if needed.
sudo apt-get -qq update
sudo apt-get -y -qq install youtube-dl ffmpeg
echo all required binaries are present, installed or upgraded as needed
echo We are good to go!
echo Have some coffee while we finish downloading and converting.
echo Downloading videos with youtube-dl binary
echo this will take some time according to your quality selection and internet speed!
youtube-dl -citA -f $Q $PLAYLISTURL
echo All videos have been downloaded.
echo If there was any problem with one or two videos are were ignored
echo Download complete!
echo Converting to mp3 using ffmpeg binary
echo this will take some time according to your processor power!
for F in *.$T
do
ffmpeg -i "$F" -acodec libmp3lame -ab $AQ "${F%.$T}.mp3"
echo all files have been converted.
echo If there was any problem with one or two videos are were ignored
echo Conversation complete!
echo we will move mp3 files to a folder called mp3 inside your selected directory
echo for easier access and seperation between video and audio files
echo Creating mp3 directory to move mp3 files
mkdir -p mp3
echo Moving all mp3 files to mp3 folder
mv -f -t mp3 *.mp3
echo File moving complete!
