OpenSUSE Hardware :: Bison Webcam Uvcvideo Not Working Anymore
Mar 5, 2010
I have been able to make my webcam work some time ago, but it does not work anymore. (I installed xen kernel recently, but I don't know whether it's related or not).
I am using Opensuse 11.2.
My webcam is a Bison uvc compatible webcam. It should work with the uvcvideo driver which is intalled by default with the kernel. My kernel is
Code:
Linux linux-61le 2.6.31.12-0.1-desktop #1 SMP PREEMPT 2010-01-27 08:20:11 +0100 x86_64 x86_64 x86_64 GNU/Linux
lsusb gives:
Code:

dmesg gives:

ZC0301 Webcam
I didn't use it for a long time. But the last time I checked it Under Ubuntu, cheese was able to read from it & gstreamer properties also tested it successfully.
But now that I need the webcam, I can't get it work
gstreamer properties says " Video for Linux 2 (v4l2): Could not negotiate format".
I have a Dell 1300 running Kubuntu 11 and attached is a Logitech Pro 9000 webcam. It works OK - in the sense that Cheese, VLC etc display correctly. I'm trying to set up video streaming for security monitoring - and because the Dell is pretty slow, I need to stream at a low rate of frames/sec to keep a reasonably low cpu utilisation. I've tried various things, but the most successful is the motion package, which I can set up with a new frame each second, which is fine. However, the motion server stops after a seemingly random period with the message ...

Motion hasn't crashed, it's still running. I also get a message in syslog ... uvcvideo: Failed to resubmit video URB (-27)
I have an HP dv4 1313dx, pavilion notebook computer. The Built in webcam seems to work OK, but I have absolutely no sound registering when I speak over webchat , or over just sound recordings when I talk at the computer. I'm not sure if it's a software issue or not. I upgraded to 10.4 beta because 9.10 wouldn't let me run my wireless card. So upgrading to the new beta version solved that, but as I said I noticed the built in mic on my notebook isn't picking up any sound. This is whether I'm using Skype, sound recorder, or AMSN for webchats.
After a lot of work I succeeded in making my Icon 225 Mobile Broadband working under Linux, so I immediately took advantage of this by updating my system.But unfortunately not everything went well. I have to say something:in Linux when you solved a problem another one pops up. And this is what happened to me. The first problem was the following error message: PackageKit Error repo-not-available: File '/repodata/repomd.xml' not found on medium [URL]
It seems that in the Online update system there is a error: or the address is wrong or something is not working as it should be. Anyway I got over it and the system started to download the updates and so on. At the end the system asked me to reboot and I did it. Unfortunately a cold shower was waiting me : the KDE interface did not work anymore, the only thing I could see was something like a fog all around the video. The mouse cursor was a dark square. I was still able to hear the welcome sound so I deduced that only the graphic interface was corrupted. I rebooted again and when the system show me the booting choices:
1) Desktop opensuse 11.3-2.6.34.7-0.3 2) Failsafe opensuse 11.3-2.6.34.7-0.3 3) windows 1 4) windows 2 5) Floppy
I chose this time the second one (I think it is like a safe mode)and fortunately it worked but the system looked like having lost brightness (I think this choice change the card driver). Now I do not know why the KDE inrface got corrupted, because I download everything from the opesuse website, so no strange repository has been installed. I checked in the little manual supplied with the DVD and I found the following suggestion: If the KDE interface got corrupted please try to remove the cache files of the KDE desktop using the following command rm -rf /tmp/kde-user /tmp/ksocket-user
A wifi card with the ath5k driver used to work properly until a couple of weeks ago. Now, if I ping the router the response times sometimes are okay but often fluctuate into the range of many hundreds or thousands of milliseconds. Occasionally the connection breaks down entirely.My laptop, which uses a different card, works fine (typical ping response times of 2 ms), so its probably not the router which is faulty.I use opensuse 11.3 x86_64, currently with the 2.6.34.7-0.7 desktop kernel and knetworkmanager
I have a canon pixma mp640. Under opensuse 11.2 64 bit the printer worked (printing and scanning via wifi). I recently reinstalled my system with 11.3 64 bit, and after installing the canon rpms and creating the printer I get the following error in /var/log/cups/error_log:
Code:
Backend returned status 1 (failed) printer-state-message="Illegal backend: Success"
In opensuse 11.2 I needed to create some links:
Code:
cd /usr/lib64/cups/filter ln -s ../../../lib/cups/filter/pstocanonij cd /usr/lib64/cups/backend
I can view my webcam in the configuration setting in kopete, but I'm not able to view my cam on skype, it keeps on showing a gray screen! I tried almost go through on the web about this.
Using openSUSE 11.2 I tried and failed to make the Logitech webcam E3500 work under Skype, although it works well under luvcview and cheese. Can anyone recommend a webcam that does work under skype on 11.2?
I installed Suse 11.4 on a compaq desktop computer. Installed a Logitech webcam. With cam programs like cheese, it is working fine. However, Logitech Webcam (C200) not working with Empathy.
Below some parts of the logfiles:
/usr/bin/lsusb: Bus 001 Device 006: ID 046d:0802 Logitech, Inc. Webcam C200 /usr/bin/lsusb -vv Bus 001 Device 006: ID 046d:0802 Logitech, Inc. Webcam C200 Device Descriptor: bLength 18
So the title pretty much sums it up. She is running a pangolin performance which came with lucid while I am running a pangolin performance which came with karmic and i upgraded to lucid (bought before her). For some reason hulu always worked for me, so I was trying to fix it on her computer too, but somehow one of the commands I told her to run made her computer not be able to recognize that her built in webcam exists anymore.
The reason that this is so hard is that I don't remember which commands I told her to run, but one of them was the instructions from post #5 on this page: [URL]. But I don't know how messing with flash stuff could have possibly screwed up her computer detecting her webcam. The drivers are definitely installed for webcam, however when she 'locate uvcvideo' it tells her that permission is denied, so the problem might be that her computer isn't giving her the permission to access the webcam drivers to use the webcam, just an idea.
After having fixed the video on my webcam to use it with Skype I want to use the microphone as well...
Skype offers two microphones that seem to be related to the USB webcam. I have tried both of them and with different settings in kmix where I see a tab called "usb camera" with a microphone slider and a tick box. There is also an option to use "audio gain control". no success with all possible combinations.
Then I tried to use the microphone with a small software called "flrec", no success either.
Using Opensuse 11.3 (on an AMD64bit machine) and the latest version of the 32bit Skype package for Opensuse. Installed via links on skype.com (inc. mentioned dependencies on the skype website)Sound works fine but my webcam doesn't. It's a creative webcam instant model number: VF-0040.It works OK in Kopete, and is recognized as ZC3xx. In Skype the only webcam option is /dev/video0 which I can clearly see is not correct.
Linux and have got some work to do on Debian 4.0. I have installed this version with the Cd image debian-40r8-i386-CD-1. I Believe this was a minimal installation.I'm in need os some packages like Bison flex.
I am trying to install logitech libwebcam but I can't get the source of uvcvideo driver. I have that driver installed and running properly and it appears when I do the lsmod, but I can't find the uvcvideo.h header file even after installing the kernel-headers and kernel-devel. Does it exist in a specific library that I should install ?
I need (for a friend) to create a "driver" disc for a webcam that is uvcvideo compatible. The webcam when plugged into my machine works out-of-the-box using the uvcvideo module.However, for some reasons, we want to include a binary and/or sources file with it.
I have downloaded the source files from http://linuxtv.org/hg/~pinchartl/uvcvideo/ , but compiling fails. (build-essential is installed). I did not compile it using sudo since I do not want to mess up what is already installed on my system. Compilation according to the enclosed INSTALL file is as simple as "make" (no ./configure).
However, make give me errors Code: /home/user/downloads/uvcvideo/uvcvideo-553dfd853cba/v4l/et61x251_core.c: In function 'et61x251_ioctl_v4l2': /home/user/downloads/uvcvideo/uvcvideo-553dfd853cba/v4l/et61x251_core.c:2500: warning: the frame size of 1256 bytes is larger than 1024 bytes
After a update that has gone bad I can't use yum anymore, I have already reinstalled the latest versions of yum and python from the RedHat site but no luck.

After long while Vmware is not working anymore.. I think because some upgrade a while ago.. but when I try to run the configure.pl then I get this error.. does anybody know what is wrong?
I installed Burg and it worked for some time. I installed some apps that I can't remember anymore and closed my comp. I restarted my computer today and Burg does not work anymore, Grub just start like before. I tried to reinstalled Burg and it changed nothing. When I check Burg-emu it shows me the right thing, like if Burg was working. Did it happened to somebody else?
i need to find the current version of bison flexzlib make if they are not installed in ubuntu or their version are outdated i need to install things.i hope i have posted the query at the right place if not please redirect it to the relevant thread adn let me know the path
A couple of weeks ago, my keypad stopped working. Not only the numbers, but all keys there. I heard it is a setting in Gnome, but I can't seem to find it.
I have a double boot system in my comp. I tried to make some upgrade in Ubuntu but everything went wrong and It's not working anymore. I can login but nothing is working. What are your suggestions in this case?
You really have to love this fantastic Ubuntu system which destroys your setup and programmes with an update.
It seems as though one of the updates made a mess of Skype this time. well done.
Ok so here is what's happening.
First i have to say that to get my sound card working i needed to upgrade ALSA. Everyhting was running fine until....NOW.
I haven't used Skype in a while but now i thought lets use it a bit. I start up Skype there is sound. but then suddenly sound is gone. video is just fine. sound is gone completelly from Skype. mic doesn't work and neither do spekers, eventhough upon launch everything works. i can't even do a test call. in fact i could do it once but the sound was messy.
also the skype seems to have crashed as i can't exit it at all. it's just keeps running as process.
anyone had something similar? any solutions? i would post this on Skype forums, but since Skype worked before and now it doesn't anymore i believe it is Ubuntu issue.
I'm a newbie in Linux (ubuntu) environment. Well my prob started as I tried to install several w-lan applications. I tried them out and deleted them again. Till (I don't remember the name of the prog) I finally shoot "network manager". I tried some things like: Second installation of ubuntu to get back internet. Downloaded some deb files and installed them in off-line mode.
But it doesn't work because some not satisfiable things happened now I tried to fix over USB live to fix it no chance. What I need is a possibility to install from USB on my first system or boot system one and USB on the same time to use the internet per switching or something like that. Maybe it's possible to update my system wile the USB system is running? Or is there a possibility to use the ubuntu CD and install all needet packages from there because network manager is already in Ubuntu. I think that all OS company's have to think about that , when they deliver a OS that you can choose or afterwords reinstall progs from the original source ...or what?
I'm trying to develop an html template parser employing Flex & Bison, but now I found a problem and I don't know if surrender, so let's see if you can guide me to the solution (if any).
[Code]...
(Here I simplified the code to make only print what it gets, but it returns a token and the text to the bison program). Now my problem is that I would like to get the unknown characters as an unique string. [using the flex file above, returns char by char all HTML code that is not a comment!].
So, Could it be possible to make a flex rule that gets the HTML code?. It is not necessary to check if HTML code is correct I do it (before parse) using expat. Also there is no need to check the resulted code it will be done by the parser or compiler of the used language.
I know that are a lot of tools that uses this kind of templates in all languages and systems... but I'm just exercising my pour flex&bison skills. Also, using my current flex file, I have to remove the string "<!--MARKUP" from the beginning and "-->" from the end of returned string to bison... But in reality, if I could manage the HTML code as a flex rule, I could solve that sednding to bison an start Token, the code and and end token.
