Saturday, August 26. 2006Apple iSight camera under linuxYes, it's possible. You can even use it for webcam chat under Kopete IM (and other probably). Firstly, the camera doens't present itself as a v4l (video 4 linux) device, so you need vloopback kernel module. This kernel module will create 2 v4l devices, usually /dev/video0 (input) and /dev/video1 (output). You'll want to install coriander and libdc1394, probably the latest versions. Plug your camera in, insert vloopback, and start up coriander. Click 'v4l' button so that coriander will start to export your camera via the vloopback module, and that's it, you can now use your iSight as a v4l device. Fantastic.
I'm far from an expert in this field, so if you have questions about this setup, you're best taking them elsewhere Update: If you're finding that your colours are messed up and green and purple, you'll need to make a change to the coriander source (effects versions of at least up to coriander-2.0.0-rc1) Thanks to Marc Roberts who pointed this out to me... I have fixed the color problem that I had with Coriander. In conversions.c, I changed the enumeration in line 32 from update: Seems my blog software doesn't allow HTML in the comments, so here are some useful links.

But the vloopback module is no longer maintained. And it does not compile under my kernel 2.6.17. There are following errors:
make -C /lib/modules/2.6.17-gentoo-r7/source SUBDIRS=/home/.modules/2/vloopback-0.97-snap2 modules make[1]: Entering directory `/usr/src/linux-2.6.17-gentoo-r7' CC [M] /home/.modules/2/vloopback-0.97-snap2/vloopback.o /home/.modules/2/vloopback-0.97-snap2/vloopback.c:1041: error: expected ‘)’ before string constant /home/.modules/2/vloopback-0.97-snap2/vloopback.c:1043: error: expected ‘)’ before string constant /home/.modules/2/vloopback-0.97-snap2/vloopback.c:1045: error: expected ‘)’ before string constant make[2]: ** [/home/.modules/2/vloopback-0.97-snap2/vloopback.o] Error 1 make[1]: ** [module/home/.modules/2/vloopback-0.97-snap2] Error 2 make[1]: Leaving directory `/usr/src/linux-2.6.17-gentoo-r7' make: *** [default] Error 2 Mfg Andreas.
Yes, you're right - that version will no longer compile - however there is a new release on the vloopback website - http://www.lavrsen.dk/twiki/bin/view/Motion/VideoFourLinuxLoopbackDevice
I've not created an ebuild for it though, but it does work. |
