Thanks for the build. I've previously tried a build from april, it has definitely improved a lot since then. It's still very far from being usable, it's very slow and has problems with ringing and temporal stability, but the detail retention is actually quite remarkable. I had doubts about this project, but if they can fix these issues, it could be fairly promising.

New demo has been released, about the perceptual vector quantization (hmm, I thought it was called pyramid VQ before, not that it matters...). |

Suitable for a visual demonstration. If the video compression artefacts are a magnitude more obvious than the JPEG artefacts, it won't hurt too much.
With low quantization, JPEG can be quite exact; and with block adaptive quantization, it doesn't even waste too much space (I just wish there was any other tool than xat JPEG Optimizer, preferably freeware, which can create them). |

Yay, I figured out how to make a static build! SDL sucks. Latest stuff, fresh from my terrible karaoke night: daala-20141118
Difficulty: Last week, the entire frequency-domain intra prediction scheme was scrapped. (Demo2 is no more.) Hopefully other improvements have made up for it. Last edited by foxyshadis; 27th November 2014 at 09:09. |

Nice! Thanks for the new build (and for making win32 build for us xp users). I must admit, the visual quality has not improved as much as i hoped for after looking at the commit log, but still, slow but steady improvement.

I'm setting up a weekly-or-so build folder: Daala builds. Check-ins are pretty slow at this point, just 2-3 a week, but hopefully things will ramp up again soon.

At the moment, Daala is not yet really useful, rather slow and with little support, just like x265 in very early development... but times will change, and it is certainly an advantage to be able to participate, your auto-builds being an important factor. |

I'd say in its current state it is more comaparable to the demonstration encoders for the various HEVC proposals. |

In case anyone missed, the Daala intra compression demo was finally officially released (I don't really get why they had it on their web for half a year before finishing it and officially releasing to the world?)
https://people.xiph.org/~xiphmont/de.../update1.shtml I think the encoded images in the comparison tool are updated to match with never versions: Quote:

There haven't been many changes in the past month, but in the spirit of the new year, here's the latest Windows build: daala-20141229

This doesn't call for jpeg at all, but I always use turbo when I build with it. It's a lot more stable, too, compared to the newer versions of ijg jpeg. My builds always include x64 too.
