Install libx264
Get the libx264 package from http://www.videolan.org/developers/x264.html.
The link to the actual file is ftp://ftp.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
Download it, then..
# cd ~/Downloads/ # tar -xjvf last_x264.tar.bz2 # cd last_x264 # ./configure --enable-shared # make # make install # ldconfig
Install ffmpeg
Just use your browser. From http://ffmpeg.org/download.html find the latest stable release, which is currently http://ffmpeg.org/releases/ffmpeg-0.8.7.tar.bz2. Download it, then...
# cd ~/Downloads # tar xvfj ffmpeg-0.8.7.tar.bz2 # cd ffmpeg-0.8.7 # ./configure --enable-libx264 --enable-gpl --enable-shared # make # make install
ffmpeg is now installed with libx264 (h264).

It works! I'm no longer getting Unknown encoder 'libx264' message.
Use ffmpeg
For example, convert a Flash video compressed using VP8 codec to H264. Am wondering which codec produces a smaller file.
# ffmpeg -i aflashfile.flv -vcodec libx264 convertedfile.mp4
Wait, and shazam! A smaller file should be produced. But you may get this message:
error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory
This error usually comes when ldconfig does not know where to search for the libraries, so, in order to help it out, on Fedora do the following:
# cd /etc/ld.so.conf.d
Add another file: custom-libs.conf
Inside, put :
/usr/local/lib
save, then do
# ldconfig
et voila again!!!
Yep, works, Fedora 15
