x264 is a free software library for encoding video streams into the H.264/MPEG-4 AVC format. It is released under the terms of the GNU General Public License.



x264 was originally developed by Laurent Aimar, who stopped development in 2004 after being hired by Ateme. Loren Merritt then took over development. Today, x264 is primarily developed by Loren Merritt, Jason Garrett-Glaser, Steven Walters, Anton Mitrofanov, David Conrad, and Guillaume Poirier.

User interfaces

x264 itself provides a command line interface as well as a library-level interface. The former is used by many graphical user interfaces, such as Staxrip and MeGUI. The latter is used by many other interfaces, such as Handbrake and FFmpeg.


As of August 2008, x264 implements more features than any other H.264 encoder.

x264 has won awards in the following codec comparisons:

x264 has SIMD acceleration on x86, PowerPC (using Altivec), and ARMv7 (using NEON) platforms.
