    How to use ffmpeg if libmp3lame support is not present

    12th April 2008

    I’m providing regularly updated compiled linux and freebsd ffmpeg binaries, and also described how to use ffmpeg on shared hostings if not all the required libraries (like libmp3lame) are present. However, the solution recommended might not “fit all”, so here is another one – simpler and even more portable/universal than setting LD_LIBRARY_PATH.

    The solution is simple – I first proposed it in the Getting ffmpeg working with flashvideo on various platforms issue page on

    The idea is: if the original audio stream in the file is already compressed (most of the time it is), then you do not need to recompress it – and do not need libmp3lame or any other audio codec! To achieve the “ffmpeg direct stream copy” functionality, you can add one of the two options:
    -vcodec copy will direct-stream-copy video (no re-compression),
    -acodec copy will direct-stream-copy audio (no re-compression).

    In other words, ffmpeg option -acodec copy should just copy the original audio from input file to output file without alteration, and will not require any audio codecs support.

    Sample command line could be (in the example, a 1-minute fragment of the input file is just copied into the output file):

    ffmpeg -t 00:01:00 -i movie.avi -vcodec copy -acodec copy preview.avi

    This tip is based on the information initially obtained from the ffmpeg-user mailing list archive for June of 2005.

      This article shows how to install ffmpeg, ffmpeg-PHP, Mplayer, Mencoder, flv2tool, LAME MP3 Encoder, and Libog from source. It should work on most systems, however may need some tweaking from system to sytem.

      cd /usr/local/src

      Download source tarballs:


      Extract the tarballs:

      tar zxvf lame-3.97.tar.gz
      tar zxvf libogg-1.1.3.tar.gz
      tar zxvf libvorbis-1.1.2.tar.gz
      tar zxvf flvtool2_1.0.5_rc6.tgz
      tar jxvf essential-20061022.tar.bz2
      tar jxvf ffmpeg-php-0.5.0.tbz2
      tar zxvf flvtool2_1.0.5_rc6.tgz

      Make a directory to store all the codecs:

      mkdir /usr/local/lib/codecs/

      Install any necessary packages:

      yum install gcc gmake make libcpp libgcc libstdc++ gcc4 gcc4-c++ gcc4-gfortran
      yum install subversion ruby ncurses-devel

      svn checkout svn:// ffmpeg
      svn checkout svn:// mplayer
      cd /usr/local/src/mplayer
      svn update
      cd /usr/local/src

      Copy codecs for mplayer:

      mv /usr/local/src/essential-20061022/* /usr/local/lib/codecs/
      chmod -R 755 /usr/local/lib/codecs/

      If you are using secure tmp:

      mkdir /usr/local/src/tmp
      chmod 777 /usr/local/src/tmp
      export TMPDIR=/usr/local/src/tmp

      Installing Lame:

      cd /usr/local/src/lame-3.97
      make && make install

      Installing Libogg:

      cd /usr/local/src/libogg-1.1.3
      ./configure && make && make install

      Installing libvorbis:

      cd /usr/local/src/libvorbis-1.1.2
      ./configure && make && make install

      Installing flvtool2:

      cd /usr/local/src/flvtool2_1.0.5_rc6/
      ruby setup.rb config
      ruby setup.rb setup
      ruby setup.rb install

      cd /usr/local/src/mplayer
      ./configure && make && make install

      Installing ffmpeg:

      cd /usr/local/src/ffmpeg/
      ./configure –enable-libmp3lame –enable-libogg –enable-libvorbis –disable-mmx –enable-shared
      make && make install

      ln -s /usr/local/lib/ /usr/lib/
      ln -s /usr/local/lib/ /usr/lib/
      ln -s /usr/local/lib/ /usr/lib/
      ln -s /usr/local/lib/ /usr/lib/
      ln -s /usr/local/lib/ /usr/lib/

      Installing ffmpeg-php:

      cd /usr/local/src/ffmpeg-php-0.5.0/
      make install

      Note: Make sure this is the correct php.ini for this server.

      echo ‘extension=/usr/local/lib/php/extensions/no-debug-non-zts-20020429/’ >> /usr/local/Zend/etc/php.ini

      Restart apache:

      service httpd restart

      Thanks for extended information! I wonder who would be the initial author of this short manual – little search gives too many results to figure it out :)

      One notice, though: this “manual” assumes that the person has full access to the Linux PC; my advice in this and linked posts is targeted at shared hosting users, who do not have sufficient access rights, but still (after some tweaking) can use ffmpeg/libmp3lame/etc for the multimedia purposes on their websites.

      nice tutorial.

    4. Mohammad Abbas Says:


      Your tutorial was just perfect, I’ve done all the steps and all exept:
      ./configure –enable-libmp3lame –enable-libogg –enable-libvorbis –disable-mmx –enable-shared
      did not work as I had to change the command to:
      ./configure -–enable-libmp3lame –-enable-libvorbis –-disable-mmx –-enable-shared
      And also remobed the –enable-libogg from the list as the new ffmpeg dose not include the –enable-libogg on the ./configure

      Thank you very much
