Quikee: add slides from SPIE and VDD

Daala is the codename for a new video compression technology.

The effort is a collaboration between the [https://www.mozilla.org/en-US/research/ Mozilla Foundation], the [https://www.xiph.org/ Xiph.Org Foundation] and any other contributors that wish to help.

The goal of the project is to provide a video format that's free to implement, use and distribute, and a reference implementation with technical performance superior to [https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding H.265].

Please see the links below or the [https://www.xiph.org/daala/ main page] for more information.

Daala

2016-09-13T21:15:35Z

Quikee: add SPIE conference and VDD

Daala is the codename for a new video compression technology.

The effort is a collaboration between the [https://www.mozilla.org/en-US/research/ Mozilla Foundation], the [https://www.xiph.org/ Xiph.Org Foundation] and any other contributors that wish to help.

The goal of the project is to provide a video format that's free to implement, use and distribute, and a reference implementation with technical performance superior to [https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding H.265].

Please see the links below or the [https://www.xiph.org/daala/ main page] for more information.
