That's exactly how it works. The example doesn't show more than one, but it will return multiple resolutions ranked with a confidence percent (the meaning of which depends on the method) as long as it's above a reasonable thr

Embarassing side-note: I've never made the mistake of trying to add an empty directory to a git repo before; if you tried and failed to build, it's been fixed.

No that isn't true. ISO (MPEG/JPEG) does not play a part in licensing patents or forming patent pools, which is only natural when you consider the fact that ISO is an international organization headquartered in Geneva and every co

I had this same experience a few years ago, though more out of necessity (my very old hardware at the time was no longer being supported.) pkgng was brand new and immature and it was an opportunity to do some fun things like create my own p

It would not be terribly difficult to create a workalike on other * nixes as the task is effectively just mapping your filesystem's stat(2) metadata onto an SQLite db, with a virtual table representing file content and a user defined f

Unfortunately both the article and the code suffer from a crucial misunderstanding of JPEG -- the 8x8 blocks do actually undergo a 2-dimensional DCT. Zig-zag scanning down to 1D comes later, after quantization, and is applied to the quantiz

VPx reference software is open source. The article is not referring to the software but the specification which is developed and published by Google (a private company), as opposed to an open standards consortium like ISO, ITU or the IETF.

According to the spec, Thor is a more traditional block-based codec with quadtree subdivisions in the vein of H.264 and forward. Beyond that the design is rather conservative and different from Daala's "start over from scratch&quo
