Hi, |
| 2 |
|
| 3 |
Recently I installed linux-2.6.34.00 (vanilla). |
| 4 |
I adopted the config file where (I thought) it |
| 5 |
need to. |
| 6 |
|
| 7 |
The previouse kernel I used was linux-2.6.32.13 (vanilla). |
| 8 |
|
| 9 |
With the old kernel I was able to use my Web Cam |
| 10 |
(Sony Playstation Eye/Omnivision ov534 according to |
| 11 |
usbview -- see below) via VLC media player 1.0.6 Goldeneye |
| 12 |
and via guvcview (I use a svn snapshot of this application). |
| 13 |
With the old kernel guvcview does not show any image control |
| 14 |
sliders but works fine so far. |
| 15 |
|
| 16 |
Using the new kernel, things are going wrong somehow.... |
| 17 |
|
| 18 |
When accessing the cam for the first time after a boot, |
| 19 |
there is often a video stream, but the image is much |
| 20 |
too bright. But guvcview offers image control sliders now |
| 21 |
even for my cam. |
| 22 |
|
| 23 |
But: Using that sliders or accessing the cam a second |
| 24 |
time after restarting as vlc as guvcview results in |
| 25 |
*nothing*: no stream, no picture. The real incarnation |
| 26 |
of a black whole. |
| 27 |
|
| 28 |
When starting guvcview from the command line it prints |
| 29 |
"device temporarily not accessible/available" or something |
| 30 |
like that. |
| 31 |
|
| 32 |
I haven't figured out whether the cam hangs or the driver |
| 33 |
goes nuts or... |
| 34 |
|
| 35 |
Powercycling of the Cam via usb unplugging/replugging does |
| 36 |
not help, though. |
| 37 |
|
| 38 |
I recompiled libv4l, guvcview and vlc when the new kernel |
| 39 |
was booted (and the /usr/src/linux symlink was set accordinglingly) |
| 40 |
but the result was the same. |
| 41 |
|
| 42 |
What can I do to access and use my webcam under linux-2.6.34.00 |
| 43 |
successfully? |
| 44 |
|
| 45 |
Below I included information about my system according the webcam: |
