Install FFmpeg and x264 on Ubuntu Lucid Lynx 10.04 LTS
Install the Dependencies
1. Uninstall x264, libx264-dev, and ffmpeg if they are already installed. Open a terminal and run the following (you can usually paste into a terminal with shift+ctrl+v). Copy and paste the whole code box for each step.
2. Get all of the packages you will need to install FFmpeg and x264 (you may need to enable the universe and multiverse repositories):
Install Yasm
3. Yasm is required for x264:
Install x264
4. Get the current source files, compile, and install. (See using snapshots if you are having connection issues with the Git server.)
Install LAME
5. This is used to encode mp3 audio.
Install libvpx
6. This is used to encode VP8 video.
Install FFmpeg
7. Get the most current source files, compile, and install. Run "./configure --help" to see what other features you can enable/disable. Nightly FFmpeg snapshots are also available.
Installation is now complete. You can stop here if all you wanted to do is compile and install FFmpeg. The rest of the guide has additional information on updating and removing the packages you just compiled.
Install qt-faststart (optional)
This is a useful tool included with FFmpeg that rearranges a file with H.264 video, "such that the moov atom is in front of the data, thus facilitating network streaming". Basically, it allows web movies to start playing before they are completely downloaded. Usage: qt-faststart input.foo output.foo.
Updating FFmpeg and x264
Development of FFmpeg and x264 is active and an occasional update can give you new features and bug fixes. To update FFmpeg and x264 you will need to remove the packages, make distclean, update the source, recompile, and install. To update x264:
Now compile x264 as shown earlier in the guide starting with the x264 ./configure line. You can update libvpx if you installed that too:
Now continue with the installation starting with the libvpx ./configure line. Now update FFmpeg:
Finish the installation starting with the FFmpeg ./configure line.
