Hey!

http://projects.powerdeveloper.org/proj ... /entry/595

Can we get a few more people to try this?

R&B :)

OK, so "Labtec Webcam Pro" definitely works. Could we collect here webcams known to work on Linux PPC? With exact name, model number, tested distribution, kernel version, used driver (if not from the distribution).

Microsoft LifeCam VX-1000 works too... Hey, it was cheap!! :-D

Distro: Gentoo and Ubuntu
Driver: gspca
Kernel: 2.6.19

I think all the camera's that work with this driver on x86 will work on powerpc.
I'm now testing a Creative Optio cam, which should work with the UVC driver, but no luck yet...

Johan.

I have used a few phillips and logitech webcams in the past years with linux on my G5 running Gentoo/PPC64. I don't think it's necessary to create a half-assed list of linux/ppc compatible webcams. Such a list would never be near to complete. IMHO most of the (webcam) drivers work on ppc as good as x86, which makes such a list useless, because it's dublicated work. (dublicated to the information found on the homepage of each driver)

Indeed. By the time you collated a list of which drivers maybe had an endian problem, the problem would be fixed, and the list pretty redundant.

It's the same reason we do not list "hard disks which spin up in time" on the Efika, or RAM modules that work on the Pegasos II.

Well, I bought an USB wifi stick based on recommendation of some x86 friends, as "best supported under Linux". Obviously it did not work at all under Linux PPC. I don't know the current status, but I know, that before buying anything for EFIKA, I'll ask here :-)

Which one was that?

rt2x00 was pretty well supported under Linux until all the developers went on an indefinite hiatus around the time we both bought RT73 sticks :)

I really can't think of a better USB Wifi stick, to be honest.. it does work, if you like bisecting git trees and repatching mainline Linux with large segments of the wireless-dev.git tree..

I don't like, so it is covered by dust over here. I use now one based on the zd1211 chip, and it works nicely and out of box with openSUSE and others.

I would also prefer a similarly easy to use webcam :-)

Hi,

Here are some information concerning the Labtec Webcam Pro device. I can understand the frustration of people buying a non-working device whereas others have already made some tests. Nevertheless, I **think** the huge compatibility chart shown on the spca5xx website should be applicable to the Efika.
Code:
stellae@tiny:~$ lsusb
Bus 001 Device 002: ID 046d:08a2 Logitech, Inc. Labtec WebCam Pro
The device requires the spca5xx driver which compiles fine "right out the box" (however I can now provide a precompiled version for a 2.6.19 kernel). You will probably have to load it with the force_rgb=1 parameter to get correct colors.
Code:
insmod gspca.ko force_rgb=1
This JPEG camera supports VGA (640*480) and QVGA (320*240) as "native" resolutions.

With 'spcaview', the best picture quality can be obtained by using the "-f r24" command line switch. 'spcacat' is quite buggy when you take single pictures (I **thing** the bugs are not related to the webcam...).

Weak point: in QVGA, there are some blinking lines at the bottom of the video (this is a known problem with this webcam, it's not ppc specific).

I should try the Microsoft LifeCam VX-1000 to see which one is the best.

Best Regards,

Stellae

This is great work. Please keep us posted. This effort will be one of the new Freescale Selected Demos...

Hi all.

OK, I have some exciting news :-D

I finally got the Creative Optia camera with the UVC driver to work. To test maximum performance, I used uvc-stream to stream 640x480 video over my LAN to my laptop.

The quality is amazing, it's much faster than what we had with Ekiga until now (will test this camera with Ekiga later) and best of all, here is the output from top:
Code:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
16282 root 15 0 39780 10m 10m S 2.0 8.7 0:04.81 uvc_stream


A mere 2% of CPU usage!


Next week I will put this set-up in my lab and see if I can make the stream publicly accessible - you will be able to see for yourself! :-)


Johan.

That is great Johan. We will look forward to that. Keep it going!

It is on the account of your steady and progressive effort, as well as Noel's that this is now a Freescale Selected Demo.

R&B :)
