Hey all,
Joe Deken, the head of New Blankets, an NGO that's sponsoring some of my Pd work related to teaching, is interested in getting the kinect working with Pd. Anyone interested in hacking a gem object together? I know I can promise at least a long term loan of a kinect camera, more might be possible. [pix_kinect] would be awesome to have.

I am working with Kinect these days for an installation. It would be nice to have this object in GEM. I can test it if you want when you have an alpha version ;) ++

hello,
i think the official answer is : install a driver for kinect, and use it with pix_video. c

Yep, of course, i forgot this method based on plug-in ! ++

I don't think there is a driver that'll just give you the video and the depth. Its like a video camera with two images per frame: the normal video frame and the depth frame. I think the video frame is totally standard, but from what I hear, the depth frame is a bit of an odd format. So right now, I don't think that [pix_video] can output two frames at the same time.

pix_video can connect to 1 hardware that can send multiple images. as a capture card with many input. if you want 2 images, you can use 2 pix_video.
so, i don't see any probleme, but i'm not the one who will make it work. c

Wouldn't it be possible to have the depth value in the alpha channel and so obtain a single rgba image?

Video4Linux1's VIDEO_PALETTE does not mention any alpha format.
Video4Linux2's V4L2_PIX_FMT does not mention any alpha format either.
In Video4Linux2's V4L2_FBUF_FLAG there are three things called alpha. They're related to overlay. That's a thing for capture cards that can write directly to the graphics card.
There's nothing really for 4 channels... well, maybe there is. There is RGGB, BGGR, GBRG, you know, the Bayer stuff that has double the resolution for the G channel, that is used in "raw" cameras. A Video4Linux driver could use that fourcc.
But I don't know whether there are any restrictions to having kernel drivers create their own fourcc as long as an app accepts it.
However, current linux support for the Kinect doesn't use any kernel drivers, right ? Both existing libs use libusb, which is userspace.

I believe that there is both: the libusb/libfreenect approach, which will work on GNU/Linux, Mac OS X, and perhaps also Windows, and the Linux kernel driver approach.

exatly. also from what i hear, the 2 images of kinect (real, and depth) are not linked anyhow, so they might run at different speeds, which makes the 2 pix_video approach even more feasible.
