Real to Offer Open Source Windows Media for Linux

cpugeniusmv writes to tell us News.com is reporting that RealNetworks plans to release an open source method to allow Linux users to play Windows Media files. Currently Linux users are able to play the two main Windows Media formats (wmv and wma) but only if they install closed-source modules. The ability to launch this initiative comes from a recent licensing deal between RealNetworks and Microsoft and the antitrust settlement against Microsoft.

Maybe I'm wrong about this, but this is how I've aways thought it worked.

Unfortunately you _are_ wrong. Case point: Go to http://www.mp3licensing.com/royalty/ and behold the royalty rates for a "decoder". Note that this patent is generally ignored but some more careful distributions like Ubuntu do not support mp3 playback out-of-the-box for that very reason.
I assume your misunderstanding is the result of the situation with the LZH-algorithm, or in practical terms, the GIF format. Thos, now expired patents only covered the LZH encoding not decoding, hence one could make, use and distribute a decoder but not an encoder. However this was just the special situation with regard to these 2 patents covering this particular algorithm, i.e. they were luckily (from the patent holder's point of view, unluckily) worded in such a way that they only covered the encoder.

Nota bene: Yes, there were indeed two patents covering exactly the same algorithm, one was held in its latter days by Unisys and was the more notorious one due to Unisys' active enforcement. The other one was held by IBM and just recently expired but IBM never actively enforced it (It would've probably fallen due to prior art anyway but it does illustrate the utter stupidity of the USPTO specifically and the patent system, especially with regard to software, generally).

That's really...

Totally false. ffmpeg / mplayer / vlc etc. can all decode WMV files *natively* using the ffmpeg libavcoded libraries.

The problem is not decoding the files, that is trivial. The problem is dealing with the copy protection. Another open source library is not going to help this, because it will still never be allowed to decrypt the copy-protected files.

Well, mostly. ffmpeg can decode WMV 7/8/9 and WMA 7/8. There is no decoder for WMA Pro, WMA voice, or WMA lossless. WMV8 decoding has bugs and may drop certain keyframes.

Actually, the latest ffmpeg can play WMV3, no windows dlls needed.

You will need to check out the latest ffmpeg svn and compile it tho.

Dear RealPlayer,

[Geoffreyerffoeg]

Please open up your own format first before going and opening up other peoples' formats. Windows Media is already easy enough to play most anywhere. Streaming (or even non-streaming) RM is a pain to convert to another format - and most of the downloadable converters require you to have RealPlayer itself already installed (so it can use the DLLs). This is as much a "solution" as Captive NTFS, and it doesn't work on platforms other than x86/Windows.

(My underlying complaint is that you don't have a half-recent version for Windows Mobile. I've tried to convert these to WMV but it doesn't work well. Releasing a WM5 player - or even a J2ME player - would shut me up for now, but your real problem is you have the obscurest, proprietariest file format ever.)

the original Trojan horse was a gift bearing Greeks, not the other way around :)

It was Greeks bearing a gift bearing Greeks. And if a few of those Greeks was carring presents, say birthday presents to give to somebody after the battle or something, then it would be Greeks bearing a gift bearing Greeks bearing gifts.

And if instead of a horse they had built large wooden bears, it would be Greeks gifting bears.

Plus, with the proclivity of Greeks to be naked, you could end up with:
Greeks gifting bears bearing Greeks being bare bearing gifts.

My head hurts now. But "What if we build a large wooden badger..." will be stuck in my mind all day, at least that's a plus.
