Xiph & Mozilla's Daala codec

Sorry, I have a real bad habit of doing that. I used it on linux, but futzed with mingw until I started working on another project and forgot all about it. I got it to build properly now, but it's dynamic, sorry about that. I have no idea how to make static builds.

daala jm branch 20140929 (commit 898f970, the most recent)

[Tommy Carrot]

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...).

They encoded their Daala images as JPEG.

o...kaaaaaaaayyyyy....

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.

[Tommy Carrot]

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.

[foxyshadis]

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.

[LigH]

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.

x265 in the very early state was a functional encoder for a completed and standardized format. Daala has not reached bitstream freeze yet, much less completion of the research phase on the format and compression scheme.

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

A windows binary from today...

The changelog available here.

[Nintendo Maniac 64]

Hey, perfect for comparing to the newest BPG (HEVC image) build that just came out today!

BFG-9000? "Big F**ing Gun"? ... Ah, no, BPG = Better Portable Graphics ... bold name.

[Nintendo Maniac 64]

Clearly you'd use it for big freaking graphics so that you don't have huge filesizes, right?

Nevertheless, typo fixed.

[mzso]

BPG didn't amaze me, it looks around equal to jpg at sizes which provide acceptable quality. And is sometimes worse, by smudging, bluring away detail.

[LigH]

Similar to WebP and WebM, both based on vpx. There are people recompressing already coarse quantized JPEG to WebP to reduce the image file size even more... nonsensical.

[mandarinka]

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:

The update text (and demo code) was originally for a July update, as still image work was mostly in the beginning of the year. That update get held up and hadn't been released officially, though it had been discovered by and discussed at forums like doom9. I regenerated the metrics and image runs to use latest versions of all the codecs involved (only Daala and x265 improved) for this official better-late-than-never progress report!

[foxyshadis]

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

@foxy : did you use the libjpeg-turbo lib or the old libjpeg one ? The 1st one should be faster...

Did you succeed to compile it as a x64 arch ?

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.
