Just last weekend I got my first Blu-Ray disk and found that it came with a warning that if I didn’t have the latest software updates on my player, it might not play. (It did play, being far older than my player.) This annoyed me enough that I’m glad to hear of an open-source, non-DRM alternative to Blu-Ray in the works. Lib-Ray is a project to create a high-definition video standard with “no DRM,” “no region codes,” “no secrets,” and “no limits.” There’s a Kickstarter page looking for funding for the project.
According to the current specification, Lib-Ray uses the Matroska (MKV) container format.
Creating a mass market for Lib-Ray player boxes sounds like a long shot, but it’s easy enough to imagine open-source software being developed and distributed that would let any modern computer play the disks. This could be a boon to anyone who wants to distribute high-quality video discs without DRM.
