DivX ;-) Deux Update 143
Epitaph writes "The author of the DivX ;-) codec (a high-quality MPEG4 codec used quite heavily by DVD pirates to recompress movies) has recently released more information about his next-generation codec: DivX ;-) Deux, or Project Mayo. MPEG4 is the future standard for internet video, and since DivX ;-) Deux is going to be free, this is a very interesting project to keep an eye on. There's now an 'Ask Gej' section where you can ask the author questions, or suggest new features for the future codec. He's also looking for coders, so help the guy out!"

the Microsoft MPEG4 codec is about a year old now, they are now pushing Microsoft Video 7, which to my untrained eye does look smother and crisper. It's also comparable to Real Video 8, which is really pretty amazing. it's hard to belive MPEG4 ISO is actually outdated.

(Super) Video CD (Score:3)
Both are essentially just an MPEG on a CD.
Video CD uses a fixed bitrate so that it plays at the same speed as a standard audio CD. Hence, you can get 74 or 80 minutes per CD-R. I believe that it's MPEG-1. It's been around for a while, and is quite popular in the Far East.
Super Video CD uses a higher and variable bitrate, so you only get 35-45 minutes per CD. If you buy the 80-minute CD-Rs, then it should be fine for archiving TV shows (a one-hour episond minus comercials tends to run 42 or 43 minutes). Obviously, this is higher quality than standard Video CD, and I think it uses MPEG-2.
My DVD player supports both formats, though most only support the original Video CDs, as that has been around much longer. (I have the Raite DVD/CD/MP3 player, purchased for $150-ish at Egghead.com.)

Realistically, though, people are going to manage to get copy-protected content out somehow.
This means that it will also eventually be necessary to disallow drivers from displaying/rendering content that is not digitally signed by an approved content provider (who can presumably be trusted not to distribute pirated content).
With sufficient legal protection and penalties (e.g. making the use of operating environments that cannot effectively implement these protections illegal (e.g. Linux and any pure Open Source OS)), this will effectively eliminate most piracy.

These figures are the results of simulated tests on the technology whenever it first came out. Simulated means that no one really knows for sure.
Besides, I suspect that, like all products' breakdown cycles, the amount it breaks down is represented logarithmically. Since CD-Rs need practically every bit of information, a CD-R will only last as long as it's weakest link. Which, of course, can easily be found out by looking at the specs. I can't remember off of the top of my head, but I suspect that they were factoring in the error correction as well, so your product will probably start to go bad before those 10-20 years are up.
Additionally, you have to ask yourself how many people out there will purchase brand-name CD-Rs? Personally, I've been going with bulk CD-Rs for a while now. Which means that I expect to have a high faulty-CD-R turnover rate. Your mileage will probably be different.

I have released my code (as I do with all my programs). An 8-bit code amounts to a single letter of encryption: it's essentially a substitution cipher.
The point of releasing it, however, is academic. My code is modularized so that if you wanted to release something with stronger encryption all you would have to do is hack out those matricies. As it stands right now, sDES can be broken quickly but also encrypts things extremely fast. I was able to encrypt all of /bin/local in a little under 2 seconds -- on a Pentium 100 (my laptop).

RIFF (Resource Interchange File Format) is a specification used to define standard formats for multimedia files and to prevent compatibility problems that often occur when file-format definitions change over time. Because each piece of data in the file is identified by a standard header, an application that does not recognize a given data element can skip over the unknown information."
From MSDN. Bassicly multimedia formats are typically "layered" files, the RIFF format has each sublayer identified with a FOURCC, all this mean is that each sub part of the the file has a label that uses four charaters.. in the case of WAV it's actually WAV(space) or for your C guys,

Motion compensation in 3D (== time) (Score:2)
My understanding of how video codecs work is that there is basically a two step process: 1) you try to simplify each frame by extracting information out of it that refers to historical data, 2) you compress the rest as graphics. The intent being that compressing the difference will be more efficient than compressing each frame anew. Makes sense, no?
so 1) is where motion compensation comes in
and 2) is where wavelets come in.
A very simple codec might be to simply subtract each frame from the preceeding one (which means that unchanging areas are black) and compress the results with jpg. More advanced systems might split the frame up into segments and do a transformation (== motion compensation / rotation) on each segment before subtraction and compression.
Now for my question: the segmentation can be very hard to get right - exhaustive search being time consuming and all that. Is anyone doing it in the time domain as well, so that not only is the previous frame searched for a good match, but perhaps the last 30 or so. If the video is very flashy (think mtv), this might work quite well.

As long as you are not using that machine to do consulting, work from home, or anything beyound home "hobbiest" type use, yes. (I'd advise against it. There are much better hobbiest OSs.)
But the big copyright holders of programs had a massively successful campaign to convince the average slashbot that this was illegal. Remember all those ads in magazines and posters in school computer clusters in the '80s ? They managed to shame huge numbers of people into buying things they didn't need to. The 700 club, usenet get rich yesterday schemes, Scientology, Albanian pyramid schemes, the Russian bailout . . . it all pales in compairison to the anti-piracy campaign.
The RIAA and MPAA are going for a repeat move on their copyright material. Ironically, inspite of the Jon Katzian "the world will change because small people have a voice on slashdot" theory, all you automatons just help them out by parroting Hollywood's false legal propaganda.
It just goes to show that you can give everybody a voice on the internet, and they'll still just repeat what they hear in TV commercials.

Where does it state that it will be free?

I can find some references to them asking for people experienced with OSS to join them, but it does not say explicitly that it is to be OS-software.

Another hack? (Score:5)
The reason why DivX got so popular is that it was the right thing at the right time. There was no technical wizardry involved, relative to projects such as LAME or Ogg Vorbis. I doubt Maxmorice or Gej can even explain the whole MPEG4 spec.
It's almost akin to someone telling you that they hacked a Palm V to have 8mb instead of 2mb, and now they have decided to make their own PDA. Hmm?
My question is - given that "An early version of DivX ;-) Deux is complete," did they hack another MS-MPEG4 codec, or are they coding something from scratch? It's been only a short time period since they announced the project, so I hope it's not just another hack (which brings to another question - how can they expect investors to put money in a company that illegally binary hacks some other companies' software?)
It's not open source if it involves MPEG patents (Score:3)
At best, an "open source" MPEG-4 implementation may be available for download in some other country without software patents. People in the US may compile it and play with it at home, but no commercial or noncommercial entity will be able to use it publicly. That means that there will be no legitimate uses for it, since no legitimate user would be willing to risk a lawsuit. The end result is that this program seems destined for illegal uses only.

I'm sure the DivX CODEC offers a lot to legitimate uses. Perhapse Ferverent's point is that DivX developers and their supporters should stress these bennifits rather than illegal use.

But one of the new things about ASF is that there is no more limitation imposed by 32-bit file size values (= no more 4 GB maximum size of a video file). And wasn't there some (pseudo) suggestion by MS to make ASF an open standard (back in '98)?
A question: What keeps MS from checking the FOURCC for DivX
One more question: Do you know about an ASF reference manual online? Microsoft did something like that for AVI, but I can't seem to find it for ASF.

a high-quality MPEG4 codec used quite heavily by DVD pirates to recompress movies
Nice to see the truth come out. Tom's Hardware [tomshardware.com] even knows this.
This is why the MPAA won the first round. This is what DeCSS.exe (Yes, the Win32 program, not the LiViD player) is being used for. It is certainly possible to transfer enough of a DVD to a 650 MB CD-ROM using this technology.
Yes I know about making backups, about control over media, etc etc but you have to admit this does make pirating movies easier (much easier than image-copying DVDs with CSS in tact).
There, now please moderate this down so it doesn't cause a flame war.

The killer "app" for Mayo-at least for me (Score:5)
I do amateur video (no, not *THAT* kind) for fun, and I know that low-rent videographers like me have been drooling over the thought of being able to make DVD's. You get durability (right now I use a tape drive for archiving video; with DVD I could master right from my archive format), pure digital format, high quality, and portability (you can play on standard home video equipment). The only problem is the high cost of DVD-R drives, media, and DVD authoring software that puts it out of reach. If you can use a standard CD-R recording a standard ISO disc (no new hardware, software, or media), all you would need is a standalone player.

As I said... (Score:2)
Naive motion compensation introduces a lot of hard edges. The MPEG4 standards supports wavelets for static image (texture) coding, but chooses 8*8 DCT for coding the residual error... I have read about lots of interesting ways to apply wavelets in video coding, for instance hierarchical motion estimation with complex discrete wavelet transforms, but its not going to be as easy as just taking out the DCT and pluggin in wavelets IMO.
As for 3D wavelet transforms, they encode the relation ship in time between corresponding pixels... people have claimed quite good compression with this (about the same quality at the same bitrate as broadcast quality MPEG-2) but it still lacks motion compensation.

ya know I really wasn't aware of this and don't really understand why that would be true. If it was a file size that would be the choice of the FS be it FAT/FAT32/NTFS whatever. If it's streaming how would it really know how big the "file" is anyway? doesn't cnn have like 24 real time streaming or something?

Cuz Microsoft isn't god. if you open a file in some "DivX" happy program it'll play. They could refuse it in Windows Media Player, but they arn't now.

hehe, ya nethier can I. What I do know is some guy wrote a program called "ASF Recorder", and judeging from the source code he figured it out pretty good. Id look at that before asking Microsoft to help you out.

Whilst I'll admit that, had I written the product, I wouldn't use the smiley, People will take the product seriously because it whips teh ass of every other codec I've ever seen.
Take a look at 405: The Movie [405themovie.com] for an example of what you can do with this codec; 7.8MB for a supprisingly good (if rather short) movie. It scales up to my 1024x768 17-inch screen amazingly for such a small file.
If I wanted to compress a movie, this is the codec I would use.

Precedent seen with strong crypto (Score:2)
Perhaps it will evolve in the way another package did in regard to strong encryption. (sorry, it's been a while so I don't recall exactly which one. Maybe Eudora.) You bought the main app, installed it, then the strong encryption was installed to it via the net from another country. It was designed that way to get around the U.S. restrictions on export of strong crypto, and allowed the package to be exported without violating U.S. laws. I can see the same sort of scheme evolving here.

Unfortunately, the DivX site stated in the article has even less technical information that Bitboys did when they released their specs for the (non-existent commercially) Glaze3D. Look at some of these quotes: ;-) Deux maintain the high standards DivX ;-) has set while optimizing the codec so that the things you use it for the most are greatly improved."
"soon, we will start releasing tools and applications for the community to kick around. Then, when all the pieces are in place, we will launch our official site and our true identity, and there will be much rejoicing."
"We are working hard to make DivX
What codec are they optimizing? DivX or DivX Deux? And as far as I know, DivX is only used to watch a moving pictures. They sound like they are re-inventing the wheel and making it the greatest thing since sliced bread (to combine two clicheéd sayings).
Bottom line is: I'll be a bit more excited when they give me a bit more details on what's going on. I have no doubt something is being done, but this announcement seems a bit too premature for me.
