Daala video compression

Daala is the code-name for a new video compression technology. The effort is a collaboration between Mozilla Foundation, Xiph.Org Foundation and other contributors.

The goal of the project is to provide a free to implement, use and distribute digital media format and reference implementation with technical performance superior to h.265.

• Next generation video: Introducing Daala
• Introducing Daala part 2: Frequency Domain Intra Prediction
• Introducing Daala part 3: Time/Frequency Resolution Switching
• Introducing Daala part 4: Chroma from Luma
• Daala: Painting Images For Fun (and Profit?)
• Daala: Perceptual Vector Quantization (PVQ)
• Revisiting Daala Technology Demos

If you're interested in our progress, or in helping out, development code is available from our working repository.

git clone https://git.xiph.org/daala.git

We have a Quickstart Guide to help you get the code built and running. Development discussion takes place in #daala on irc.freenode.net. (→web interface)
And on the daala@xiph.org mailing list (archives)

For overall progress and goals see daala notes on the Xiph.Org wiki.

For some of the ideas we've worked on, see Tim's presentation slides, "An Introduction to Video Coding", from the Auckland meeting in January, 2012. Video recordings of the presentation are also available, but unfortunately not for the first part day.

• Part 1: Transform Coding (no video)
• Part 2: Entropy Coding part 2 or webm HD (starts at slide 51)
• Part 3: Probability Modeling part 3a part 3b or webm HD part 3a HD part 3b (starts at slide 92)
• Part 4: Motion Compensation part 4a part 4b or webm HD part 4a HD part 4b (starts at slide 139)
