Some 1up mushrooms for you. SVG sources are available here.

Woops!

Well, the video told me to. Funny, yet so true.

I just noticed that the song Do It 2 Nite’s chorus is a sample from SOS Band’s Take Your Time (Do It Right).
However, there’s literally no attempt to make the sample any different from the other. All they did was speed it up a bit, increase the bass and add a highhat, and add some effects. Lame!

The fact that they got the credit for coming with a bouncy house track is even worse - the sample is basically the entire chorus. Appalling.
Almost like Daft Punk’s Digital Love, though, I’d have to admit, at least they only used a few seconds of audio, rather than the whole damn chorus. Their Harder Better Faster Stronger use of Coca Cola Baby was pretty darn hard to beat, though; I think they’ve redeemed themselves.

Sorry, none for you, Rockefeller.

Attention those coming to LCA!

I’m considering having a BoF (Birds of a Feather) conference during the conference relating to Bongo and stuff. I’m asking here because, well, I honestly have no idea how many are going to come. If I don’t have enough numbers, there’s probably not all that much point in putting up a request for the room. Also, if you’d like to come, if you could optionally give me an idea of when you’d like the BoF to be held (ie which sessions), so that you don’t miss out on your favorite talks!

To quote the programme:

This year we have a dedicated Birds of a Feather room that is available during the main conference (Wednesday to Friday). More information on running or attending a BoF session will be available when the conference opens.

I guess I could always generalise it, and possibly get a few other speakers involved. I might email this idea to chat/mel8ourne list.

Also, if you want to catch me at LCA, PM/email me. Mobile number is 0401215248.

Good to see the Banshee crew push out a new release from the 0.13 series. Few minor improvements which make things a bit nicer, but generally Banshee ‘trunk’ is going to be the big one.

The new Last.fm playlist source is absolutely smashing. Cheers to Gabriel Burt for that. Last.fm the way it was meant to be.

Yes, it’s that damn good. Why else would I bother to blog?

I will be traveling away to the null void for about a week until the 9th of January. You probably won’t be able to contact me during this time, since I won’t have ‘net access or anything; if you email me, it’ll stay in the backlog of mail and spam until I get back. Or, if you have my number, you could call me.

TTFN.

r5u870 is a terrific little driver written by Sam Revitch that provides support for Ricoh R5U870 webcams.
The original driver itself supports the following devices:

05ca:1810 HP Pavilion Webcam - UVC
05ca:1830 Sony Visual Communication Camera VGP-VCC2 (for VAIO SZ)
05ca:1832 Sony Visual Communication Camera VGP-VCC3 (for VAIO UX)
05ca:1833 Sony Visual Communication Camera VGP-VCC2 (for VAIO AR1)
05ca:1834 Sony Visual Communication Camera VGP-VCC2 (for VAIO AR2)
05ca:1835 Sony Visual Communication Camera VGP-VCC5 (for VAIO SZ)
05ca:1836 Sony Visual Communication Camera VGP-VCC4 (for VAIO FE)
05ca:1870 HP Pavilion Webcam / HP Webcam 1000

Now, since the kernel doesn’t come with this driver, I couldn’t use my webcam on my laptop. Sucky.
After a bit of researching, I found that this appeared to be the driver I needed. So, I clicked on the link to download the driver off Sam’s website (http://lsb.blogdns.net/ry5u870/ via the Wayback Machine). Guess what? The site’s down. Damn.

After a bit of peeking around in different places, I managed to download a .deb from here and took the source from the upstream/ directory inside. Haha, now I had the source.

I installed the linux-headers-2.6.xxx package (kernel-source on OpenSUSE 10.3; they’re headers package doesn’t work AFAIK) and compiled. Success! Go-go-gadget modprobe. The module loaded OK, but the driver didn’t detect my webcam. I went back and checked the original device support list - my device wasn’t there. It was actually a VGP-VCC7 (05ca:183a), which wasn’t built into the driver. Another quick Google sent me here. Ah hah, so I needed to patch the driver so it could support my device, and extract the firmware from the original driver.

After I had applied the patch, and got the firmware going, I compiled and installed. Finally, it seemed to have worked!
I fired gstreamer-properties and tried to test the video input - it failed. After installing xawtv, I ran it and see what came up - my webcam. Apparently it doesn’t like being run through GStreamer, which sucks, ’cause that’s where Cheese is at.

So, I spent the rest of the weekend debugging, and compiling, and debugging…

At the end, I came up with this: r5u870 0.10.1. And it works! See? (please don’t ask what happened to my eye, I must’ve been blinking at the same time, or something.. =)

r5u870 0.10.1 is actually modified version of the original device driver, that has several advantages:

• Properly implements V4L version 1 query functions. While version 1 has been obsoleted, it’s still necessary to have support for it as a number of apps still use it, including GStreamer’s v4lsrc element (v4l2src is on the way, I believe it’s in gst-plugins-bad at the moment).
• Native support for VGP-VCC7, including supplied microcode.
• Can compile against Linux kernels 2.6.24+. OpenSUSE 11.0 Alpha 0 uses this at the moment, I expect more distros to start using it sooner or later.

If you want to download or contribute, head over to it’s wiki page. I should probably note I’m merely the maintainer of the driver until Sam comes back from the null void, if that happens. I might attempt to get this into the current kernel tree, too.

Possibly a sign of things to come: mediati.org (all but SVN), ayhja.com and few other domains with client hosting were down, needed to login to Plesk to manually restart the VPS. Apparently had been like that the majority of the day.
Great. Just great.
