ZDNet’s new digital camera blog

January 10, 2008

I’m not exactly in the market for a digital camera, being cheap as hell, but if I was, I’d be reading Janice Chen’s new blog at ZDnet.

How Microsoft and Apple are screwing users on multimedia, how to avoid getting screwed … and what Ogg files are and how to play them on your system

April 17, 2007

vorbisdotcom.pngSorry about the long title, but some things just piss me off so much. In this case, I want to make it clear that Microsoft isn’t 100 percent to blame — maybe 80 percent, since half the times that Microsoft tries to add value to their operating system, software companies that make money downstream by selling you stuff that would be made obsolete by that added value start bitching about it — and the feds tell MS to back off.

And while I’m no Microsoft apologist, the consumer often gets screwed in the process. But that doesn’t have to happen. There are some excellent free antivirus programs out there (I prefer Avast), and just about everybody knows that Open Office can replace MS Office, GIMP can replace Photoshop, Firefox subs for Internet Explorer, Thunderbird and Evolution (not to mention Yahoo! Mail, Gmail and the like) replace Outlook … (and, of course, Linux can replace Windows, if you’re so inclined).

So now on to my point — and I do have one. The state of multimedia — audio and video — on the Internet is a big hot mess. Microsoft controls the Windows Media format. The MP3 format, which can get you a swift summons from the Recording Industry Association of America, has recently led to lawsuits over royalties for use of the format itself — and besides that it’s lossy and sounds compressed. Apple’s AAC is somewhat more accessible, but there still is licensing and proprietary technology involved, and Apple Lossless is another proprietary format.

But there is an alternative: the Ogg Vorbis standard for audio and Theora for video are free, open-source alternatives, and Ogg is the primary multimedia format being used by Wikipedia. For true audiophiles, Ogg’s FLAC codec — used by the Philadelphia Orchestra for its online muslc offerings — allows for compression but is lossless, unlike MP3 and AAC.

But can your computer play them. (Go to the Ogg Vorbis site for setup info, or keep reading). If you have a Linux box, you’re in luck — just about all the players on that platform can handle the audio Oggs, and many (including mplayer, xine, helix and VideoLAN) support the Theora video format as well.

But what if you have a Windows box? Windows Media Player handles MS’s own audio/video format and will play MP3s, but it won’t play Ogg files without a helper app. Luckily you can play OGGs on a Web page (as Wikipedia does on this C.P.E. Bach excerpt) if your browser uses Java.

Or you can download an application that will make your Windows Media Player (or other player) able to handle Ogg files. So if you are running Windows Media Player (which I do — I happen to like it), download and run the program, and then download an Ogg file (like this version of “Giant Steps” by John Coltrate from Wikipedia), right-click on the file, then left-click on Open With and then navigate to Choose Program and choose Windows Media Player as the default app for Ogg files. Then when you click on an Ogg link on Wikipedia or elsewhere, the file will download and play in your Windows Media Player

For Mac OS X users, there are some players available that will handle Oggs (again, check the Ogg Vorbis page), but if you use iTunes (and what Mac user doesn’t?), there’s a plug-in to enable it to play Oggs.

And for all of these platforms, the Democracy Player is open source and handles just about every video format on the Web, including Theora.

Bottom line: In this case, Microsoft and Apple should add Ogg support to their players straight out of the box. Nobody would complain, sue or petition the government if they did. Users should not be steered toward and forced to use restricted file formats when free, quality open-source alternatives are available. Luckily there are work-arounds for this problem, as I have described above, and I encourage all of you to implement them on your own boxes, tell others about them and help your fellow users do the same.

I did a bunch of sweeps through the “oil paint” effect in IrfanView, along with some tweaking of the brightness, contrast and color. As I’ve said before, the program’s relative lightness is one of its main attractions. It loads in seconds.

And for bread-and-butter Web image processing, it’s got all you need.

This took about 2 minutes in Gimp. The “oilify” filter (under Filters — Artistic) allows you to get a much more dramatic effect than with IrfanView.
