bigmammoth writes "Wikimedia has been a long time supporter of royalty free formats, but is now considering a shift in their position. From the RfC: 'To support the MP4 standard as a complement to the open formats now used on our sites, it has been proposed that videos be automatically transcoded and stored in both open and MP4 formats on our sites, as soon as they are uploaded or viewed by users. The unencumbered WebM and Ogg versions would remain our primary reference for platforms that support them. But the MP4 versions 'would enable many mobile and desktop users who cannot view these unencumbered video files to watch them in MP4 format.' This has stirred a heated debate within the Wikimedia community as to whether the mp4 / h.264 format should be supported. Many Wikimedia regulars have weighed in, resulting in currently an even split between adding the H.264 support or not. The request for comment is open to all users of Wikimedia, including the broader community of readers. What do you think about supporting H.264 on Wikimedia sites?"
