“…Designing a royalty-free video codec is a challenging problem. 1 Using tools and techniques that differ substantially from those used by the common commercially-licensed codecs can reduce that challenge. Over the last several years in the Daala project, 2 we have experimented with a number of such tools.…”

The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered codecs. Part of our strategy is to replace core tools of traditional video codecs with alternative approaches, many of them designed to take perceptual aspects into account, rather than optimizing for simple metrics like PSNR. This paper documents some of our experiences with these tools, which ones worked and which did not. We evaluate which tools are easy to integrate into a more traditional codec design, and show results in the context of the codec being developed by the Alliance for Open Media.
