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.
Some articles on Lib-Ray:
JPEG2000 thumbnails
I’ve been trying to find software for batch generation of thumbnails for JPEG2000 images. So far this is what I’ve looked at:
Kakadu is commercial software that looked hopeful at first, but the licensing is confusing. The description of the “Non-commercial, Named User Licence” says it “can only be purchased by individuals, Academic Institutions, not-for-profit organizations and libraries which do not gain financially by using this software,” but the license itself doesn’t say anything about licensing to institutions, only individuals. Our attempts to get a clarification have gotten no response. If they ignore us when we want to buy something, that doesn’t bode well for support.
OpenJPEG has its supporters, but it has a command line API which can’t create JPEG, GIF, or PNG, and it can’t create images of a specified size. There are C functions which may or may not be directly callable, but the documentation for them is really scanty.
ImageMagick didn’t seem appealing at first because of its command-line orientation, but it may be the best option. JMagick provides a JNI connection. The documentation indicates it can generate images of a specified size and format, which is what we need.
If anybody reading this has other suggestions, let me know.
