webcam issues (Logitech orbicam on Acer)
Hello there,
I have troubles with my embedded webcam.
$ lsusb
Bus 001 Device 003: ID 046d:0896 Logitech, Inc.It used to work fine a while back in Ubuntu 32-bit but now I get bad image mostly made of garbled green lines and garbage (using cheese) or a green image (using skype).
I use Arch 64 so I don't know if this is Arch-related or 64-bit-related or whatever else it could be.
I'd appreciate some guidance.
Thx.

Re: webcam issues (Logitech orbicam on Acer)
No, it doesn't change anything.
Note that for skype I get
$ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype
ERROR: ld.so: object '/usr/lib/libv4l/v4l1compat.so' from LD_PRELOAD cannot be preloaded: ignored.what goes up must come down

Re: webcam issues (Logitech orbicam on Acer)
I had the same problem with skype on 64-bit Arch.
The solution that works for me:
Install lib32-libv4l from AUR
start skype with LD_PRELOAD=/opt/lib32/usr/lib/libv4l/v4l1compat.so skype
I have also tried cheese and it works.
Hope this will work for you too.

Re: webcam issues (Logitech orbicam on Acer)
Maybe it is loading the wrong driver.
As far as I can tell you need the linux-uvc driver for a logitech orbicam which is part of the latest kernels.
Did you load the uvcvideo module?
If not try modprobe uvcvideo as root.
At least it is now loading v4l1compat.so with skype 
I don't need the LD_PRELOAD part to start cheese.

Re: webcam issues (Logitech orbicam on Acer)
Far out idea here, go to /home/yourusername/.skype/config.xml and insert something like
<Video>
<CaptureHeight>240</CaptureHeight>
<CaptureWidth>320</CaptureWidth>
<Fps>30</Fps>
</Video>inside the <lib> thing (I don't know how to call it). CaptureHeight and CaptureWidth might not be needed but I leave it here as a reference.
You seem to get a bit of an image so thats a start, I used to get a strange distortion too with skype until I figured out that some combinations of fps/resolutions would do that.
Maybe you can try guvcview from the aur and test the fps/resolution combinations allowed/reported by your webcam, it's a nice program that will let you test that and do lots more with your webcam and maybe it will help you sort out your problem.

no, my driver is vc032x, and it's correct from what I know.
@ROOKIE
editing skype config file didn't help. It doesn't seem it's a skype-only issue anyway.
I'm currently compiling guvcview.
I'll post if I get any progress.

Re: webcam issues (Logitech orbicam on Acer)
It seems that it can't get access to your webcam (because some program is already using the webcam??) ..... just for the sake of testing, try running guvcview as root.
Also you may want to consider googling around and see if any other users had the same problem and if they had more luck with another driver.
In ubuntu it seems that the gspca driver might be used and not uvcview. Maybe you can try to boot ubuntu from a livecd and check if the webcam works and if it does look at the loaded modules. Check this thread http://ubuntuforums.org/archive/index.php/t-926101.html

Re: webcam issues (Logitech orbicam on Acer)
Hi,
In doubt ask the developer :-)
From what I make of your log, /dev/video0 (Avermedia M115 ) is your tv card and /dev/video1 is your camera
so you should start guvcview with: guvcview --device=/dev/video1 --verbose
If you have any problems please fell free to contact me.
Best regards,
Paulo
[EDIT]
In the first log, guvcview, detected your camera in /dev/video0, but the device index seems to have changed in the second log.
Make sure when starting guvcview that the Init. device is the one referred to as Camera. The Pixel format is YVYU and is supported since this latest version (1.0.0)

Re: webcam issues (Logitech orbicam on Acer)
@R00KIE
I tried running guvcview as root but it did not help. I think I have a 64-bit Kubuntu CD somewhere at home, I'll give it a try in a few days...
@assisp
Hello Paulo, welcome on this board. It's nice to see a 3rd party dev wandering here.
Yes my camera is currently /dev/video1, maybe camera and TV card happen to be swapped at boot time (no big deal).

Re: webcam issues (Logitech orbicam on Acer)
The error seems to come from the driver itself not guvcview
{ pixelformat = 'YVYU', description = 'YVYU' }
{ not supported - request format support at http://guvcview.berlios.de }

It's not unseen a driver that loads but then fails to support the device properly, trying with something known to work and googling a bit may solve the problem very quickly .... or cause more doubts

Re: webcam issues (Logitech orbicam on Acer)
For some strange reason the format is not being detected has valid by guvcview (in fact there is a "small" bug in the code but in this case it shouldn't be a problem, however I have fix it in svn so you could try building from there), in any case you should try forcing the format: guvcview --device=/dev/video1 --format=yvyu --verbose, like I said the format is valid since version 1.0.0
Has for the switched indexes, if you hot plug your camera it should always come up has video1 since the tv card is loaded first it gets the first available index in this case 0 (video0), if you cold plug the camera then probably it will get index 0 instead, (usb gets loaded before pci, I think), if this is important you can create a udev rule so that your camera always gets the same device name.
Best regards,
Paulo

Re: webcam issues (Logitech orbicam on Acer)
Forcing YVYU doesn't change anything. FYI my camera is built in my laptop.
Like R00KIE I think this is a driver (or kernel) issue. Or even bad hardware, who knows. I'll give a shot to Ubuntu live CD, both 32 and 64-bit so that I'll figure out if it's worth to investigate further.

Re: webcam issues (Logitech orbicam on Acer)
It must at least produce some different output :-(
If not, please try svn:
svn co http://svn.berlios.de/svnroot/repos/guvcview/trunk
the driver is reporting a valid guvcview format, so the error you are getting is for sure from guvcview not the driver, I really would like to fix whatever problem is causing the failure.

Re: webcam issues (Logitech orbicam on Acer)
OK, found the problem, not a very small bug after all.
It should be fixed in svn.
It is such a big bug that I'm releasing a new patched version 1.0.1

Re: webcam issues (Logitech orbicam on Acer)
Ok, just remember that your camera is supported by gspca (vc032x module) driver, this driver lacks several features, like frame size listing, so you need to set the camera resolution from the command line:
guvcview --device=/dev/video1 --size=widthxheight --verbose
By default guvcview tries 640x480, if this fails, gspca should return the nearest valid resolution and then guvcview uses this instead.
I don't think changing fps is supported by gspca, but I could be wrong.
In your case, you should try different frame sizes (160x120; 320x240; ...). I have a old logitech pro5000 that supports both MJPEG and YUYV streams, in the case of YUYV at low fps it only streams the top part of the frame, very similar to your case. At 25 and 30 fps it streams the entire frame (this is a known firmware bug).
Best regards,
Paulo

Re: webcam issues (Logitech orbicam on Acer)
Actually we have made a lot of progress 
GSPCA support in guvcview is for the most part untested.
I don't know many people with gspca devices so this is proving a gold opportunity to test this code.
Anyway if you could just bare with me, i'm pretty sure I can fix it.
Please could you apply the following patch to version 1.0.1:

Re: webcam issues (Logitech orbicam on Acer)
Well I think I've detected the problem,
it should be fixed in svn.
I'll wait for your output to released a new patched version.
Best regards,
Paulo

A window manager is availableMy video output is similar to that of my second post. And I cannot change any video setting (framerate, resolution). But I assume this is normal, no?

Re: webcam issues (Logitech orbicam on Acer)
Like I said with gspca you can only change resolution from the console, fps in your case is set by the driver depending on resolution.
Please try other resolutions to check if the problem persists.
I'll will release a new patched version (1.0.2) today.
Best regards,
Paulo
