    On July 23rd, x265 was announced (also here for more discussion). This has the tentative blessing of the x264 devs, and the hope is to eventually integrate it with the other projects on Videolan. It's still in an early stage (and pretty slow at the moment), and actively in the process of taking the HM reference code and rewriting/optimizing it to properly be GPL rather than the 3-clause BSD, but it is possible to generate samples with it that Mediainfo recognizes as HEVC/H.265.

    [snipped out]

    The remaining pieces that need to fall into place for proper support of the format are the decoder currently in OpenHEVC's libav branch to get committed (and then make its way into FFmpeg, most likely through qatar), and for the draft that MPEG put out for putting HEVC into MP4 to be officially approved, which will allow L-SMASH to implement it (GPAC already has somewhat, but they aren't known for being absolutely spec-compliant; plus, GPAC is ridiculously bloated and finicky to cross-compile). The method for storing it in MP4 will also be necessary for it being officially added to Matroska.

    2013-08-04: Removed the -DNO_EARLY_RDO_EXIT option; it's been removed from x265's build system too.
    2013-10-15: Updated instructions here. There's proper install rules now.
