Interesting piece of information in the #videolan IRC channel today: the X264 encoder (producing the video format commonly used in MKV and MP4 movies) is now capable of producing Blu-Ray compliant video.
Until now, the free software world was not equipped with anything capable of producing Blu-Ray video discs. With the video encoding now taken care of (Blu-Ray audio can be produced with free AC3 audio encoders), all that is left is the authoring tool. This should be less of a challenge than writing the encoders. The VLMC movie creator project which uses the VideoLAN library (which in turn contains the X264 library) will hopefully pick up this exciting new capability.
