The script uses these programs:

1. youtube-dl    (In ubuntu, you can get it by typing : sudo apt-get install youtube-dl).

2. ffmpeg   (Again: sudo apt-get install ffmpeg)

3. avimerge (part of the transcode package: sudo apt-get install transcode)

The script will download videos from youtube, convert them into avi files, and finally merge them into one avi video.

To use the script, you need call it from inside a directory with only one file in it: file name needs to be “links” and it should include the URLs of the videos you want to download from youtube, one URL per line, in the order you want them to appear in the merged video. The output will be a file “all.avi” in the same directory. Of course, you’re free to modify this script to let be more flexible etc…

Here is the script:

#!/bin/tcsh



# download movies

set x = 1

foreach line (`cat links`)

        youtube-dl -o vid$x.flv "$line"

        @ x = $x + 1

end



# convert from flv to avi

foreach file ( *.flv )

        ffmpeg -i "$file" -ab 56 -ar 22050 -b 500 -s 320x240 -vcodec copy -acodec copy "$file".avi

end



# merge all avi files into one file

avimerge -i *.avi -o all.avi



# remove intermediate files

/bin/rm vid*.avi vid*.flv

Please ignore the “BASH” title of the script, it’s because GeSHi doesn’t support csh, and as far as I know bash is the closest thing to csh

Hope it helps somebody
