isight doesn't work

[mon]

Binary package hint: linux-source-2.6.22

Hi

The built-in apple isight web cam on the macbook core 2 duo doesn't work. I've copied the firmware in /lib/firmware but this doesn't seem to be enough.

Any ideas?

Thanks

[mon (javiermon-deactivatedaccount)]

using tribe 3 (gutsy) x86

[ruebezahl (ruebezahl)]

same for me on a macbook pro core 2 duo (15")
in gutsy tribe 3 and feisty

"sudo lspci -vv" would be helpful.

[ruebezahl (ruebezahl)]

requested lspci..

[Chuck Short (zulcss)]

Actually a lspci -nvv would be even more helpful.

[ruebezahl (ruebezahl)]

so, here you are.
let me know if you need more outputs :)

Try using the driver from gentoo. You can get it from http://gentooexperimental.org/~genstef/dist/linux-uvc-0.1.0_pre100.tar.gz
The patch is already applied in the tarball. Simply do make && make install.
Works for me with a MacBookPro C2Duo in ekiga and mplayer-svn with ubuntu kernel 2.6.22 from git.

I can confirm. Using this procedure worked on feisty:

sudo modprobe -r uvcvideo
sudo mv /lib/modules/$(uname -r)/kernel/ubuntu/media/usbvideo/uvcvideo.ko /lib/modules/$(uname -r)/kernel/ubuntu/media/usbvideo/uvcvideo.ko.original
sudo apt-get install libusb-0.1-4 libusb-dev linux-headers-$(uname -r)
wget http://files.i-nz.net/projects/linux-kernel/isight/uvcvideo-isight.tar.gz
tar -xzvf uvcvideo-isight.tar.gz
cd against-revision-100
make
sudo make install
sudo modprobe uvcvideo
gst-launch-0.10 v4l2src ! video/x-raw-yuv,format=\(fourcc\)UYVY,width=640,height=480 ! ffmpegcolorspace ! ximagesink

now when I run gst test I receive this error:

Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /pipeline0/v4l2src0: Cannot identify device '/dev/video0'.
Additional debug info:
v4l2_calls.c(404): gst_v4l2_open (): /pipeline0/v4l2src0:
system error: No such file or directory

This is on te same machine: MBP c2d 15, gutsy up to date. *not* santa rosa edition.

I am currently running gutsy up to date on a MacBook Pro santa rosa edition, the isight works well.

Whith ekiga i had this bug: https://bugs.launchpad.net/ubuntu/+bug/131222 (just four first line of the webcam has been shown) I update pwlib and ekiga works without any problems.

And for gstreamer I have to used this command line to make it works:
gst-launch-0.10 v4l2src queue-size=2 ! ffmpegcolorspace ! xvimagesink

instead of this:
gst-launch-0.10 v4l2src ! ffmpegcolorspace ! xvimagesink

This bug has been fixed in the cvs version i have made a patch for the current version of the gutsy package if someone is interesting in i can post it.

[Daniele Dellafiore (ildella)]

Yes, I can confirm it works also on MBP 2g (gutsy up to date). My script on comment
#9 was wrong cause in gutsy the /media/usbvideo folder has been moved, so the second line becomes:

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

I removed "kernel" from path.
Now Ekiga detects iSight and it works.
The gstreamer test still fails (either one) with this output:

Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /pipeline0/v4l2src0: Could not negotiate format
Additional debug info:
gstbasesrc.c(2062): gst_base_src_start (): /pipeline0/v4l2src0:
Check your filtered caps, if any
Setting pipeline to NULL ...
FREEING pipeline ...

Maybe this is related to bug 131222.

The Gentoo driver works for me on 'linux-image-2.6.20-16-generic', version 2.6.20-16.32.

[Gabriele Tassoni (gabriele-tassoni)]

The bug is still present on 2.6.22-14-generic, isight can be initialized only at 320x240:

gst-launch-0.10 v4l2src ! video/x-raw-yuv,format=\(fourcc\)UYVY,width=320,height=240 ! ffmpegcolorspace ! ximagesink

otherwise it freezes (on all attempts at 640x480 or by using gstreamer based applications like cheese that defaults to 640x480).

So, bug still present for gutsy users.

[mon (javiermon-deactivatedaccount)]

I've tried what gabriele said and it also happens here.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
