Hi all,
I'm trining to configure media-video/motion but when I start it it gives me the following error...
How it is possible that
| Code: | #motion

[0] Thread is from /etc/motion.conf
[1] Thread started
[1] Failed with YUV420P, trying YUV422 palette: Invalid argument

[1] sync error in proc 31797: No space left on device
[1] sync error in proc 31797: No space left on device

|
with the same configuration file, and the same webcam on an other box it works...

Sometimes permissions on filesystems can trigger these kind of messages

permissions for root??? Don't think it is the problem...
anyway | Code: | aperta-mente ~ # ll /dev/video0
lrwxrwxrwx 1 root root 10 8 giu 00:44 /dev/video0 -> v4l/video0
aperta-mente ~ # ll /dev/v4l/video0
crw-rw---- 1 root video 81, 0 8 giu 00:44 /dev/v4l/video0
|
any other ideas?

Hello,
The error message in this case means: USB bandwidth exceeded.
Try to connect the camera to a different USB port, it might help... Unless you have nForce4 based motherboard as I do (the camera worked on my old PC). I had the same problem with spca5xx (20060501) driver on my motherboard. My solution was to modify the spca5xx driver to request for less badwidth for the camera.
So far my camera works without any problem.

I am using a nforce401 motherboard and have the same problem. Could you please show us how you modify the driver or submit a patch to spca5xx? Thank you very much! |

Hello,
this is the patch, which seams to fix the problem. Do notice, that this is NOT the correct way to fix it, but since I don't know any other way...

At home I have the spaca5xx ebuild in my overlay, so it patches the driver when I'm re-installing it via portage. I can put my spca5xx overlay directory somewhere, so you can download it, if you need it.
And for the sake of interest here is the link to my mail in the spca5xx dev mail list with more details and some (two - to be precise) response from the spca5xx developers:

I don't understand how can I apply your patch, you can explain to me in a few words?

Membris-Khan:
The easiest way is to create an overlay for the driver:
If you are not familiar with the portage overlays, please read for example this before: http://gentoo-wiki.com/HOWTO_Installing_3rd_Party_Ebuilds
You can get the ebuild, patch, etc from here:
http://www.kotiposti.net/ujfalusi/gentoo/spca5xx-overlay.tar.bz2
Now create a directory in your overlay: media-video.
Extract the package to this new directory (it will create the spca5xx dir inside).
Now you can re-emerge the spca5xx driver, which - hopefully - will use the ebuild from the overlay.
I'll hope it helped...
Let me know if you need more information.

Is there something similar applicable to the current gspcav1 driver? I am having two Logitech QuickCam Communicate STX cameras connected which I wanted to use with ZoneMinder. One camera alone works quite well but as soon as I try to use the second one I get the following error:
| Code: | init isoc: usb_submit_urb(0) ret -28
[spca5xx_open:1954] DEALLOC error on init_Isoc |
I already had a look at gspca_core.c but couldn't find anything matching. Thanks in advance.
