I would like to point out that Cisco has published the initial source code for the H.264 codec. You can find it from the source code links at

There still lots of work going on build, test system, other architectures etc. If you want to read the code and see what is there, feel free to browse. If you are feeling brave and like living on the bleeding edge, go ahead compile it, and try out. Be warned that significant refactoring is happing as this gets moved to support the binary module. The binary module will not be up till early next year.  There is a bit of information about what is supported at The appropriate mailing list for discussing it is and you can subscribe at 

There is also a 5 minute video that helps explain the "open source code" and "binary download" and other IPR issues as that seems to cause confusion for folks. You can find it at

Development and maintenance will be overseen by a board from industry and the open source community.  Furthermore, we will provide a binary form suitable for inclusion in applications across a number of different operating systems (Windows, MacOS, Linux x86, Linux ARM and Android ARM), and make this binary module available for download from the Internet. We will not pass on our MPEG-LA licensing costs for this module, and based on the current licensing environment, this will effectively make H.264 free for use on supported platforms.

I firmly believe that with H.264 we can achieve maximal interoperability and now, do it with open source and for free (well, at least for others – its not free for Cisco J)
