HOW-TO: iSight setup

ivesjd · 01:14 PM

Should be working now (11/10/2007)

Quick and easy iSight setup

As of 10/27/2007 on Gutsy. Thanks to cyberdork33 for the fixes to get this working.

In this how-to, there is no need to mount your OS X partition.

Code:

sudo modprobe -r uvcvideo
sudo mv /lib/modules/$(uname -r)/ubuntu/media/usbvideo/uvcvideo.ko /lib/modules/$(uname -r)/ubuntu/media/usbvideo/uvcvideo.ko.original

* Install prerequisites, libusb-dev, you might need kernel headers that match your kernel

Code:

sudo apt-get install libusb-0.1-4 libusb-dev linux-headers-$(uname -r)

* Download the new all-in-one bundle, with firmware autoloader as provided by Ivan N. Zlatev by clicking here .
*Change directories to where the tar file is. Then untar it.

Code:

 tar -xvf uvcvideo-isight.tar.gz

* Now build and Install the uvcvideo module

Code:

cd against-revision-140
sudo make
sudo make install

* Load the module

Code:

sudo modprobe uvcvideo

Now it should work. Here is a test you can run to see it in action.

GSTREAMER TEST

Code:

gst-launch-0.10 v4l2src ! video/x-raw-yuv,format=\(fourcc\)UYVY,width=640,height=480 ! ffmpegcolorspace ! ximagesink

There is a bug with newer kernels and the uvcvideo module. Upgrading will likely break it.

If you are a kubuntu user you will need to install gstreamer to run the final command.
I installed gstreamer0.10*, though it's probably possible to do it with a bit less.

Another problem I encountered was when I mounted it, dmesg said the following

Code:

[28959.720000] Linux video capture interface: v2.00
[28959.828000] uvcvideo: iSight: firmware successfully loaded.
[28959.828000] uvcvideo: Found UVC 0.00 device <unnamed> (05ac:8300)
[28959.828000] uvcvideo: No valid video chain found.
[28959.828000] usbcore: registered new interface driver uvcvideo
[28959.828000] USB Video Class driver (v0.1.0)

This can be fixed by running

Code:

modprobe uvcvideo trace=15

If that fix works, add it to your module options.

you need at least gstreamer0.10 to use cheese too if you want that.

Heya!

Thanks for what seems to be a great howto!
I've got a problem tough.

The dmesg says this when I modprobe uvcvideo:

Code:

[  782.604000] Linux video capture interface: v2.00
[  782.608000] usbcore: registered new interface driver uvcvideo
[  782.608000] USB Video Class driver (v0.1.0)

When I run the test I get this:

Code:

ramvi@ramvi:~$ gst-launch-0.10 v4l2src ! video/x-raw-yuv,format=\(fourcc\)UYVY,width=640,height=480 ! ffmpegcolorspace ! ximagesink
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
FEIL: fra element /pipeline0/v4l2src0: Cannot identify device '/dev/video0'.

Try rebooting. The correct module should load this time, then try the test again. It looks like one of the many errors I've gotten before try to get this to work right. I don't really have a solutiion because I just kinda fiddle with it until it starts working.

I have tried that - same error

I am getting the same error in gutsy now.

Gutsy here as well

cyberdork33 · 10:13 PM

did you try with that recent kernel update? I was hoping that might fix it.

EDIT: answering my own question here... It still does not work.

I found the bug report on this. It appears to have started with a kernel update in feisty.
