CODE

$ sudo passwd root

Enter a password and switch to the super user account by typing:

CODE

$ su -

You will now have a super user bash terminal (#). Copy the following command and paste it into the super user terminal to install the needed libraries:

CODE

# apt-get install quilt libsdl1.2-dev libogg-dev libvorbis-dev liba52-dev libdts-dev libimlib2-dev texi2html libraw1394-dev libdc1394-13-dev libtheora-dev libgsm1-dev liblame-dev libxvidcore4-dev libfaac-dev libfaad2-dev

Go to a build directory. Since you're logged in as root, use the default build directory:

CODE

# cd /usr/local/src

Now get the ffmpeg source package:

CODE

# apt-get source ffmpeg

Get the patches for ffmpeg and apply them. Click HERE and save the file in /usr/local/src/:

CODE

# cd ffmpeg-0.cvs20060823
# bzcat ../ffmpeg-0.cvs20060823_enable_amr.patch.bz2 | patch -p1

You should see something like:

CODE

root:/usr/local/src/ffmpeg-0.cvs20060823# bzcat ../ffmpeg-0.cvs20060823_enable_amr.patch.bz2 | patch -p1
patching file debian/rules
patching file libavcodec/amr_float/decoder.c
patching file libavcodec/amr_float/encoder.c
patching file libavcodec/amr_float/interf_dec.c
patching file libavcodec/amr_float/interf_dec.h
patching file libavcodec/amr_float/interf_enc.c
etc..

Now build the deb packages:

CODE

# DEB_BUILD_OPTIONS="risky" dpkg-buildpackage

Go back to the src directory and install the resulting deb packages:

CODE

# cd ..
# dpkg -i ffmpeg_0.cvs20060823-3.1ubuntu1_i386.deb libavcodec0d_0.cvs20060823-3.1ubuntu1_i386.deb libavformat0d_0.cvs20060823-3.1ubuntu1_i386.deb libpostproc0d_0.cvs20060823-3.1ubuntu1_i386.deb

Open /etc/apt/preferences using your favorite text editor and add the following lines:

CODE

Package: ffmpeg Pin: version 0.cvs20060823-3.1ubuntu1 Pin-Priority: 1001
Package: libavcodec0d Pin: version 0.cvs20060823-3.1ubuntu1 Pin-Priority: 1001
Package: libavformat0d Pin: version 0.cvs20060823-3.1ubuntu1 Pin-Priority: 1001
Package: libpostproc0d Pin: version 0.cvs20060823-3.1ubuntu1 Pin-Priority: 1001

Get the youtube-dl script which allows you to download YouTube movies in flv format, to your hard drive. Click HERE and download the youtube-dl script anywhere on your hard drive. Now, from the root termina, run these commands to make the script available for all users on the Ubuntu machine:

CODE

# cd /where/you/downloaded/the/script
# chmod +x youtube-dl
# mv youtube-dl /usr/local/bin

Download movies from YouTube by using the script:

CODE

$ youtube-dl youtube.http.address.while.viewing.video

The movie will be saved to something like I_KRmU2dO2M.flv

Finally, convert .FLV files into MPEG:

CODE

ffmpeg -i I_KRmU2dO2M.flv -ab 56 -ar 22050 -b 500 -s 320x240 video.mpg

Convert .FLV into XviD .AVI with MP3 Audio:

CODE

ffmpeg -i I_KRmU2dO2M.flv -ab 56 -ar 22050 -b 500 -s 320x240 -vcodec xvid -acodec mp3 video.avi

Enjoy!
