Ever tried to transcode into H.264 using ffmpeg in Debian Lenny just to end up with this message

Unknown encoder ‘libx264′

Here is how you solve the problem:

1. Download the debian-multimedia-keyring package
2. Install it dpkg -i debian-multimedia-keyring_2008.10.16_all.deb
3. Add the Debian Multimedia repository to your sources.list
4. Run apt-get update and apt-get upgrade
5. Install the libx264 and ffmpeg packages; apt-get install libx264 ffmpeg or apt-get --reinstall install libx264 ffmpeg

Good luck!
