Open MPEG-4 Codec Contest
chrizzzz wrote to us about the opencodex.com contest to write a Open MPEG-4 Codec. They've got an industrial sponser now, so the first team/person to do it wins 50,000$US. The contest page has speifics about the project.
He is a scary possibility. What if the mpaa sues the contest organizers and throws teh authors in prison for copyright voliation. Since the decss case has shown that providing a service that can be used to for ilegal services is now a crime.
:-(
I would be afraid to submit code there for obvious reasons.
Steempy yoo idiooot!
Yeah, the guy who wrote cp lost his house over it.
With all of the recent legal difficulties relating to multimedia coming to the forefront these days it seems obvious to me that contributing to the development of another implementation of an "open" codec such as mpeg is not necessarily the greatest idea. Given all that has happened lately with codecs such as mp3, aac (yes, I know they are audio codecs but that's not the point), and others, doesn't it seem obvious that furthering these formats in any way is at best somewhat risky and could actually hamper future research and development of other free software? I do feel that there is definately a need for a free, cross-platform, high quality video codec, but I don't think mpeg-4 is the way to go. Why not work on an open source, patent free project like Ogg? As far as I know, there has already been some development on a video codec for the Ogg project and it seems that there are some very good ideas that are being planned. If vorbis is any indication of the kind of results we can expect from the rest of the Ogg project, then this, at least to me, definately seems to way to go. I say to hell with mpeg and all the patents and legal bs... let the open source community develop a REAL free opensource codec, and watch the corporations weep. If anyone is actually interested in this I would suggest the Ogg Project Homepage as a starting point.
Well, I'm going to check it out because the AVI plug-in claims to already play MPEG4-encoded files (.ASF).

I don't think this would be a GPL violation. Plugins are under the category of dynamically linked code which RMS has stated is not a violation of the GPL.

Whoops. My apologies.
Er, I think it didn't originally have headers. Or it doesn't have headers that are as extensible as Quicktime's format. But maybe I should have just stuck to the BMP (RGB? BGR?) analogy that I was sure of.
You might be able to leverage that when writing a codec.
Because, it'll be released under the GPL when complete. Then, it can be brought to Linux and other free operating systems immediately, and not at Apple's leisure (once a non-Quicktime player is wrapped around it). We need free codecs and we need them now.

I hate to say it, but the above poster may have something there. For something like this, we need a "killer download" instead of a "killer app". Something that the vast majority of people would want to see enough that they'd overcome their natural disinclination to install software to be able to see it. Generally, that implies one of the following:
Barring any of that, we'd need an agreement from some reasonably influential company (e.g. Paramount) to release online trailers and such in the new open format, which brings us back to square one again.
One other point about the porn route -- being the equal-opp people we are, we'd have to make sure that there's something for everyone. Ms. Portman in her skivvies is one thing, but does little for the female and gay male contingent who'd prefer, say, Ewan MacGregor. ;)
Any other ideas? Are there other routes? And within the suggestions above, how would one go about implementing one or more on a practical level?

The lack of a decent open source multimedia framework is IMHO holding back Linux etc from making a real dent in the multimedia market. Apple have Quicktime, and Microsoft have DirectShow (which is a DirectX enabled version of ActiveMovie which was a 32bit evolution of Video for Windows).
What's needed is a standard method for decoding a stream of data using a variety of plugins that can be pushed to a display and audio output.
Such a system would need to playback video that covers everything from low bandwidth streaming through to DVD quality. So support for MPEG-1, MPEG-2, and MPEG-4. There are a few other codecs that are important including Sorenson (Quicktime's primary codec these days) and Microsoft's MPEG-4 Version 3 implementation (the high quality compression format that DivX is hacked from). It would also be nice if Real playback was possible, but I imagine that is very proprietery and secret...
Isn't KDE or GNOME doing something about multimedia?
First of all, they made a spelling mistake, not a grammar mistake. Second, you made a grammar mistake and a spelling mistake. Third, you aren't funny so fuck off.

Ummm...this is MPEG-4, the next generation video compression cocec, not MPEG-1:Audio Layer 3 (MP3)
This will hurt open source if people take it seriously. The rules aren't well defined, so there is sure to be controversy over who wins.
It will be worse if the contest folks don't show up with the money in a timely way.
Well, sort of... MP3 files do have a header. It's not the same thing as a wav file, however. There's nothing in a wav data segment to tell you anything about it's format. However, if you know the data is 44.1/16bit/stereo, you can play it back from any byte (+/-).
You certainly cannot playback an mp3 from any random byte. It has to be started from the begining of a block. There's a header for each block with the playback information.
FYI, you can put mp3 audio data in a wav file. "WAV" is only a file structure.
You missed the point. To those highly skilled and highly paid software gurus for whom 50k is "nothing", it would be trivial. The fact of the matter is, those people don't do anything for free -- even though there's a 50k$ payoff, it'd still be "free software".
And yes, I do think it would be trivial. There isn't more support for these things under linux because those with the abilities don't care. In fact, alot of programmers get rather pissed every time they get close to linux with anything remotely complicated. Gfx work under *NIX has always been a pain in the ass.
If by "well over 50k/year" you mean 2x or 3x, then you're on target. Skilled programmers can make anywhere from 50k to 250k per year depending on who they work for, what they write, and where they are. I would submit that even if you made 250k, making 50k for a "trivial" bit of code would be worth the time. (If you're that skilled, it's not a hassle; it's a few "bored" weekends.)
The likely "winner" will be a team of people, not a single god-like programmer.
Oh, you mean actions like posting rants as an AC? Good point, I stand corrected.

VERY TRUE!
.Sorenson truly is a great codec. It could be argued that Sorenson 2 compresion beats the stuffing out of anything out there (though only in 4:3 aspects). However, it also true that it ignores the *nix platform completely.
I work with digital media for my tuition, and codec choice is half the game. On the user side of things, oftentimes I have found that exotic codecs will need to be downloaded and installed seperately before the 'AVI' or 'QT' movie can be played.
Re: codecs. .
The idea behind this contest is a good one. In light of the relative excellence and popularity of codecs like sorenson, we need something like this or the *nix's will be cut out of the streaming media revolution. (cliche, but true--everyone's gotta have it these days.)

I'm too lazy to dig up the FSF's page on this topic, but you can write GPL'ed plugins for proprietary apps; you just need to include an exception in the license.
AFAIK, Apple has announced that QuickTime 5 will support MPEG-1 and MPEG-2 (or support them better than QuickTime 4), but they have not announced MPEG-4 support. If anybody has proof that I'm wrong, please correct me because I'd like to see MPEG-4 support as much as the next guy.
Well, admittedly I don't know what it would take to write a codec, encoder, ripper, or whatever. But if it really is only a "few bored weekends" then of course it would be worth it. You sure it would be that "trivial"? If it was there would be a lot more support for this stuff on Linux. Anyone know what exactly is involved in writing a codec? Basically it's just floating point number crunching yes?

50k really isn't that much to the person who's qualified enough to write what the're talking about. The winner(s) would have to be quite skilled in c in which case then certainly make we'll over 50k/year so it's probably not worth the hassle. Anyone else is probably dreaming if they think their semester course in c is going to be enought to write something that can win.

Because the QuickTime player is the de facto standard on Apple systems. It would be nice if you could play DiVx (or however it's capitalized) inside of it.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Nope. I'm looking for Ispell implemented in perl, not interfaced to in perl. It would be better if it were all done in perl so that slashcode would not need external libraries or programs to run. Not that I have any idea if it needs them now.
Also, to those who are worried about the dictionary, if it were Ispell-ish then you could have any number of dictionaries. I leave which dictionaries should be implemented as an exercise to the reader, and the /. staff. It would, of course, also need some way to store dictionary additions for users. I suspect this last point is the reason it hasn't been implemented.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
That sucks. I don't think I'm alone in saying that the Quicktime player really, really sucks (this subject came up before, and I was definitely not alone). It's bug-ridden, and the interface blows.
I have a feeling this is more political than practical, which I find very annoying. Yes, I know a lot of people don't like Microsoft, but there is no question that Media Player is way better. If you're going to pick a proprietary player, why not pick the one that is 1) more useful to more people, and 2) technically better.

Sometimes it's best to just let stupid people be stupid.
once the codec is created, how can acceptance be encouraged
What we need is a clip of some hot babe willing to take off a decss t-shirt for the open source cause, encoded with this codec. Porn is allways how standards get established, thats why vhs won our over beta.
You mean play all those proprietary codecs for which you can't even obtain documentation for under NDA? Quicktime 4 stuff ain't gonna happen. Sorenson and Apple won't let anyone have at that. Not even M$ can play those, you have to use Apple's player. And M$ asf ain't gonna happen either. That one's the M$ proprietary MPEG4 standard. And Real Networks won't let anyone get at realvideo. Even for the Intel Indeo codec, you have to sign an NDA. With just the one xanim guy coding at it, it's not going to get very far. So what's there left to play? I guess there's MPEG1 and MPEG2, but those files are HUGE.
And we aren't going to get decent playback performance unless there's some hardware acceleration available in X, which there isn't. But why bother with that now, when we can't touch any decent codec.
Well, that's what these MPEG4 contestants are trying to do. They're trying to make an open GPL'd codec based on the MPEG4 reference. I was just trying to explain to the guy why this matters. Designing your own codec from scratch is supposedly really really hard. But I don't think we have to, we can use the MPEG4 reference codec. Assuming that there aren't patents we'd be infringing on, of course. The cable modem guys have said they wanted to come up with an open MPEG4 codec to use for streaming video. Not for normal TV broadcasts, MPEG2 is better for that. There was a previous slashdot article on that. So the other advantages of doing MPEG4 then is that there is already a lot of demand for an open codec and there is a lot of industry acceptance of MPEG4.
Because for the same price of hiring one decent programmer for six months they can get a bunch of suckers^H^H^H^H^H^H^H people to write software for them and then pick and choose which implementation to use.
On the bright side this would make a great project for a college-level graphics class... It could help someone's tuition.
But when I read the prize included a free Macintosh, I threw the code away.

Free OSs don't need a codec, they need a free version of the quicktime API allowing other quicktime codecs and applications to be ported to linux easily.
Also the QuickTime Player may suck, but that's only one player. The player is a simple application which tells quicktmie to play quicktime data or play a URL like rtsp://blah.com/somemovie.mov
People who complain about the player just don't get it.

I think it's at http://heroine.linuxave.net/quicktime.html Is it possible to make an open mpeg4 codec? There are some issues with mp3 audio (that's why vorbis exists) but mpeg4 video is okay? I don't have a clue today (-night).

Okay, so the thing originally shows up as a Quicktime plug-in. As long as the source is open we can fix that. I suspect the media player version will be released a day later.

I think this little contest is an interesting, if not inventive, initiative to get a long overdue product to be developed in a much shorter timeframe!!!
The unfortunate aspect, in my mind, is that the criteria for the new application was not a bit more ambitious. Obviously this project will get quite a bit of attention - especially after being featured on /.!!! My complaint is that originators of this little venture did not seize this opportunity more effectively and put all of the intelligent minds that will be working on this venture to a bit more of a challenge.

Stop being so contrarian. Your snottiness far exceeds your actual knowledge and abilities.
Then the whores come in, shaking their rumps for the menfolk.
It's not clear if you specifically mean video codecs, and the definition of "come out" might be stretched, but Ogg Vorbis appears to be a very good music codec (even partially completed), and it is open source.
;)
Give this stuff a chance - the real thrust of open source development only reached critical mass a year or two ago (assuming it even has!), and it takes time to develop these scientifically complex projects. The reason we've so far seen Unix reimplementation and catchup work could simply be that those are the relatively easy tasks, as well as representing the infrastructure for future open source work. There just aren't that many people who get into highly refined fields like perceptual encoding, but those who do invariably do it from sheer internal drive, not because they want to get rich quick. Whatever the other arguments for or against open source media codecs might be, I don't think the added financial incentive of propriety is going to be a real issue here. And even if it were, it seems that many companies grok the sell-service-not-software business model and are willing to bankroll the development of new codecs and techniques (Ogg is an example again).
As for the deep scientific angle on codec development, it's often overstated - a lot of successes come from good luck or from treating human subjects as black boxes. The story of how the MPEG-1 layer III algorithm was refined by one engineer listening to Tom's Diner a few hundred times comes to mind.
Why not make MPEG-8 instead? Aim higher folks!

is there any open source project at the time dealng with multimedia under Linux?
the community could really use a good player/encoder with the ability to play or record all the popular encoding formats.
It would be one less argument against using Linux.
If there's one thing I miss on Linux, it's good Codec support. I'd love to see a good, high-quality encoder come out of this, much like the LAME project did for mp3's.
...and if an open one is written, I'm sure all the other free OS people will be very happy too...

They insist that it be released under the GPL but that it also must be available as a QuickTime plug-in as well as a plug-in to all kinds of proprietary software?
I seem to recall there was some debate about GPL'd browser plug-ins, and I forget how the IANAL's sorted it out? Does anyone know if these plug-ins might violate the GPL?
sigs are a waste of space
There are likely intellectual property issues that will scare away any potential commercial use of an Open Source MPEG4 codec.
Agreed, but there are several in development. For example, I am working on libmedia.
Linux multimedia is definitely hampered by the lack of a reasonable codec that everyone can use to view stuff. So there are people likely at work on this already. Add a $50K bounty, and suddenly a lot of dusty projects are going to get a good polish-up, IMUO. ;)
OTOH, once the codec is created, how can acceptance be encouraged? If Quicktime players refuse to include it (for example), we're back to square one, aren't we?

mpeglib will also let you play divX's on Linux - it wraps the Windows CODEC.
http://mpeglib.sourceforge.net/
Total effort to do what???
It's not at all obvious to me what they actually want.
They obviously know about the ISO MPEG-4 source since they provide it, and this is freely licenced. You still need to licence the MPEG-4 patents though, as you still would if you reimplemented the CODEC yourself.
It's also rather bizarre that they have provided the Microsoft (was that publically released?!) MPEG-4 source in addition, since anyone getting anythign from it will probably be infringing on Microsoft's copyrights and patents.
So what's the goal here? If you want an MPEG-4 implementation and are willing to say "screw the patents" then just use the ISO source. Reimplementing it won't help. Given that MPEG-2 has similar patent issues yet MPEG-2 open source CODECs are available without (yet) any heat from the patent owners, I'd say just use it!
IANAL.
So you like that fact that you can't watch most Quicktime movies on Linux? If I had said "Fuck Windows Media 4.0" nobody on /. would give a damn. But since Sorenson isn't an MS product, people feel compelled to defend it, regardless of whether it deserves defending. Sorenson is a proprietory compression codec that locks out a good part of the computing population from watching most Quicktime videos.

Geez. Touchy touch. I know what Sorenson is, I hate it for obvious reasons, and I can't spell it. Knowing how to spell something != knowledge of it, or vice versa.
Sorenson is doesn't work on BeOS, never WILL work on BeOS, and nearly all the internet's MPEGs are encoded in it. Understandably, I am eccstatic (see I probably spelt that wrong as well!) about anything that will help get rid of it. I thought "fuck Sonorson (okay, I spelt it wrong, sue me)" got it across, but apparently you don't seem to understand subtlety (probably spelt THAT wrong as well!)

Why aren't there any clear, objective criterion on their site for determining if a submission is correct and/or working satisfactorily (whatever that may be)?
Will occasional jumpy video and/or audio during playback disqualify a submission? How will such a measurement be quantified -- or will it be a strictly subjective determination? Would a partial implementation be acceptable in any way (the MPEG-4 standard is fairly extensive from what I can gather)?
If two or more submissions all "work" OK, what criteria will be used to distinguish and rate/rank them? Is this, too, something perhaps yet to be decided? Does the submission date/time take precedence?
Unless and until there are some very clear answers to these sorts of questions, I'd caution anyone against devoting too much time to it, unless you're absolutely not doing it for the money. You may find out that they awarded the prize to Mr. Heeza Good Friend rather than Ms. Sheez Justa Stranger...

A quick look at the code looks disappointing; too few comments, and C++ written with a C programmer mentality. This is more of an illustrative implementation than production code; there's lots of memory allocation and deallocation within inner loops, and some things that obviously should be inlined are not. I doubt that this code will play in real time.

Some operating systems are not capable of providing synchronized multimedia because of features built into them to thwart covert channels. For example, their schedulers jitter the CPU time values so one process can't use the amount of CPU time it uses as a covert channel to leak classified information to another process.

Once, I downloaded a QT file that Media Player (Windows 2000) couldn't play the audio to. So I fed the QT file into Cool Edit. My suspicions were confirmed; instead of audio and video being interleaved at an incredibly tight interval, there were about 1-second snippets of sound separated by video bursts. I cropped out the video part and ba-boom, I had a funny as hell South Park sound byte!
Considering the QT4 player, I've only seen it on a mac (where it should be), and I am proud to say that the likes of it have never tainted my Win2000 machine. I do like Media Player, but I use Winamp for mp3s, since it has the oscilloscope readout. By the way, does anyone know of a codec (Winamp DLL or otherwise) that lets you directly open the .cin files for Quake2? I hate going into 320x240 software just to properly view the cinematics (anti-aliasing stinks with movies, except in the Q3 .roq files)

A video player or codec coded in Java is worthless, especially for such a high-compression high-raw-datarate format such as MPEG-4. What I want is LESS Java, not more. I'm sick of all these stupid Java applets, codecs and source files tainting my screen and critically delaying running times.

no comments, don't be a fool. let say 1000 people try it... you all get paid 50$ for trying... and all the benefits are going elsewhere... and the lucky 50 000$ recipient worth much more...
You're not supposed to be a serious platform for graphics and content. You're supposed to be a server. Now get me some soup, bitch.
When most people talk about Quicktime, they mean the Sorecnsor codec. It's actually possible to create and play Quicktime movies on Linux right now - as long as they're not using Sorenson, which 98% of Quicktime films do.
;-).
Likewise AVI can be a wrapper for a number of film formats, from MPEG1 thru VOB thru DivX
MPEG 1 AVIs work right now under aKtion, the KDE medis player.
It uses Windows DLLs for CODECs and can play AVI, MPEG2, MPEG3, SMPEG, QT...
How are we supposed to be a serious platform for graphics and content if we can't even play the stupidest movie clips? (/RANT)
The codec should utilize MPEG-4v.2 video motion compressors or something of equal quality, source code available on this site. /. discussions I remember that there are quite a few... I think it's not in the interest of those who want to create an open codec that this codec will be 'illegal' like DivX ;-).
;-) seems to make it a promising project.
.xyz files will always play, everywhere! Create a small cross-platform player (maybe based on GTK) for people to download.
If it's not only something similar in quality to MPEG-4 but uses MPEG-4 itself, what about all the patents? From earlier
On a similar note, can anybody say what the guys at Project Mayo are doing? Sounds very mysterious, but the line Our members include the creators of DivX
It would be great to have a codec that is cross-platform, free, open-source, and performs well. And please don't put it into QuickTime -- I know that it's only a 'wrapper format' for all kinds of content, but I don't want to be forced to use that stupid QuickTime player anymore. Design the codec as a library in a way that you can make a QuickTime plugin from it if you want to. Give it a file extension of its own, so that all
As another person mentioned, they plan on releasing this code under the GPL (not LGPL) which will be violated when the program is run through the QuickTime interface that is a requirement of winning!
Also, by not forcing people to be MPEG4 compliant (according to the rules your code must be MPEG4, or something with 'better quality'), the resulting codec may not be open standards compliant, which in many ways nullifies its existence...Do we really want open platforms like Linux to still have their own different set of codecs? I guess having a 'different' codec beats having obsolete ones... but most web sites (etc) will use something more standard, regardless of quality. Unless the codec is SUPER COOL and ported to many platforms, in which case the author could likely make much more than $50k off of it by other means.
Lastly, I looked through the site and didn't find any information on how this will be judged. Image quality alone? Or code quality? Or time to code? Anyone?
