Ubuntu Multimedia :: Get A Very Pixelated Image From The Webcam?
Aug 9, 2010
I'm writing to ask for help with a quality issue when using my webcam on sites like chatroulette, and even testwebcam. My webcam, albeit not a very expensive webcam, is quite decent quality, the box claims that it is 2.0 megapixels but... I'm not too sure. However-- When using this webcam on flash sites, the quality drops - it seems - from 640 x 480 to a measly 160 x 120. I get a very pixelated image from the webcam, but using it in cheese it works perfectly fine, at 640 x 480.
The webcam also works on windows, and the quality is fine on flash sites. But, I wouldn't want the only reason to be using windows to be chatroulette. Here are some screenshots comparing the qualities, the first being a screenshot of the webcam in use on [URL]... and the second being a screenshot of the webcam in use in cheese. I probably look like a bit of an idiot in both of the pictures, apologies for that.

I've been using RecordMyDesktop to do some simple videos (no fancy effects) and when I play them back, they are all jaggedy and pixelated and barely viewable.

I have a problem making work a webcam. At the begining, after the instalation of 10.04 in a new laptop, the webcam did not work but with a lsusb I see that the webcam was Webcam 5986:0241 acer. I was not able to config neither use the webcam with any application. After lots of test and forums reading I could not do my webcam to work, and now when I do a lsusb my webcam does not appear.

I'm install a genius web cam eye 312 in fedora 11. The image is upside down in all the programs. In amsn there is no colors, and image upside down. In skype, chesse full colors very nice, but image upside down.
amsn give me this information:
v4l2 : usb camera (93a:2622)pac 7311.
The command Lsusb give me
Bus 005 Device 002: ID 093a:2622 Pixart Imaging, Inc.
So I think there is a problem with the driver it self.

I have Asus Eee PC T 101 mt. Running SuSE Linux 11.4, KDE version 4.6.0 (Release 6).
The image from integrated webcam is inverted. The image can be upturned to correct orientation by ticking the "Upturned" effect in Webcam (wxCam) application. However, these options are not available in Skype or Google video, or probably in all other services using webcam. Other person in video chat sees my inverted image. Is there a way by which I can correct the situation?

Just purchased a webcam and it worked immediatelly with kopete. This was in the configuration dialog, a small window showed me moving around in all my gloriousness. Now realise why those horror films show this sort of footage.
Thing is: how to make the image bigger, fill the screen? Is there a program? Don't say rtfm, I don't know enough to do that.

whenever I video chat with someone the image from my webcam is clear but the video from the person on the other end is messed up. It is as if it does not render correctly, it's washed out and it looks like a full image and 2 cut off images, one on the bottom and one the top of the full image. Has anyone else encountered this? The PC has a Radeon 9800 Pro AGP card with the ATI drivers installed. Other video plays fine, ....., dvd, avi and mkvs.

Using Slackware 13.0. Have a Microdia web cam (60fc) and was (still am) looking for a simple free application to test it. Found a site which identified the drivers, modules, etc. needed so was checking my messages file and noticed that the Image Sensor HV7131R is not always identified as being detected when booting: kernel: usb 1-1.3: HV7131R image sensor detected Is this a problem or what?
I found modules videodev, V4L2, but could not find compat_ioctl32 and it is not listed in the modules loaded. Is this correct? Could not "find" it. I see usbcore listed during booting but does this mean it is a module? or a driver? or what? Also cannot find the an appropriate module that is for either ehci_hcd or uhci_hcd related as both of these appear in the messages. Also I see that the camera is for SN9C105 bridge and know that the "sn9c105" is supposed to be included in "sn9c102" module(?) but the SN9C105 camera notation does not always appear in messages. Is this correct? or (I think) I am confused by the numbering and cases used, i.e. what is a module (loadable?) a bridge and why change cases? Can someone straighten me out? Are all modules loaded listed by lsmod or just the loadable ones and usbcore etc. are "modules" loaded at another time?

Since the introduction of the new ubuntu startup screen (in 10.04 I think), I have seen this neon green pixelated border around the white ubuntu text and the 5 dots. It is by no means impacting my productivity, but some of us enjoy having an OS that looks good It starts the moment the decryption screen comes on that asks me for my password (which is the first ubuntu screen I see, after grub).

I have set the hotkey for "Very short backwards jump" and "Very short forward jump" to "Left" and "Right" respectively, and yet pressing the left and right arrow key does not work. Plus when I play the video in fullscreen the subtitles look pixelated.

I upgraded from Karmic to Lucid via Terminal, and everything is working nicely. However, after switching the desktop on, the OS loads OK up to GRUB loading, when new Plymouth is supposed to kick in. But all I get is a pixelated image. The five dots still flash correctly signalling the OS is loading. Apart from that, I did not notice anything else wrong.
Just to check whether it was the upgrade process to have gone wrong, I did a fresh install of Kubuntu RC, this time. As soon as I inserted the live CD, however, I could tell the end result would be the same, for the same pixelation appeared while the CD was loading. And in fact, after installation, I got the same problem (see uploaded photo). So, I'm guessing, maybe it depends on my graphic card? I'm on a Matrox G450, which has always worked fine (for example, on Kubuntu it uses kwin without a hiccup). I'm currently on Kubuntu, but the issue occurs both on it and Ubuntu, where Compiz is deactivated (don't even know if that matters), and I'm only on Metacity. If Plymouth can't be correctly displayed by my card, shouldn't it have a sort of fall-back mechanism allowing users like me to have a close-to-normal experience?

I tried to install a a custom splash screen using this guide [URL] and got as far changing the settings with Startup Manager. I found out that I didn't have an 'Appearance' tab so I reverted all the changes I've done in the 'Boot Options' tab. I then closed Startup Manager and rebooted back into linux. Now instead of seeing the purple Unbuntu screen, I see a black screen with a lot of pixelated garbage. Why I don't have the necessary tabs in Startup Manager to install a theme? I'm using a Macbook Pro 5,5.

Using webcam component of XawTV package as supplied with Ubuntu 10.10. My implementation seems pretty basic, just needs to snap every 5 seconds and ftp to web site. It actually works just fine, but only for an hour or so. Then process continues to run, but image does not update. Kill & restart webcam and it works fine again, until it doesn't. Video stream in XawTV window is fine throughout, so I don't think there's a hardware problem.

I am a recent convert to Ubuntu 10.10 from Vista. I work from home and do all of my work via remote login and video conferencing through Skype. In Vista, I could use my DV Camcorder as a webcam which, in turn, gave me video for Skype. In Vista, I used a program call "Tracker Cam" which I could run, and then it would act like a video driver for Skype and presto, I had perfect video in Skype.
Now that I am in Ubuntu, I am trying to achieve the same thing. I can hook up my DV Camcorder (A Sony Handycam HDR-HC5) and see the live video through Kino. However, this doesn't help me with Skype. I still can't enable video, or select a video device in Skype. I have Googled this up and down with no leads.
So, I am wondering if anyone has done this with Skype (or other programs) to get their DV Camcorders acting like webcams for video calls or is this just one of those things that won't work in Ubuntu?

purchased a webcam to record videos with in Ubuntu. I plugged it into the USB slot (and audio into the mic hole) and it seems to work ok. But I'd like to record a video from it and save it to a file. How can this be done?I tried Cheese and no audio was recorded.I tried GUVCView and it was fine except for slow video & audio delay.I can't find any other programs for recording webcams on Linux.

I'm using Wubi to dual boot 9.10 off windows xp. I have been having very good luck figuring things out using this ubuntu forum, which I am more grateful for than any of you could ever imagine, But I have a webcam issue I just can't figure out. Heres my question. I just recently bought a VERY cheap usb webcam from a company named HDE. There doesn't seem to be a specific name or even model number for this webcam, but here is the web page of the webcam I bought, http://www.hdeshop.com/USB-3-LED-PC-...B0015TJNEY.htm The website only provides drivers for windows vista and windows xp, but I figured there might be a chance or possibility that I could force this webcam to work on ubuntu 9.10. I plugged in the webcam and it did show up in skype, but the picture is all green and there is a double of me.
Plus, the actual webcam device will not show up in skype, I can't select the webcam, but regardless it still shows a green double vision image when I test it or do a video call.Skype seems to be the only thing this webcam kind of works with, It will not work with Cheese though and doesn't show an image in gstreamer. I want to mention that when I go to Cheese Preferences there is a webcam device that appears and sayse "USB 2.0 Camera (/dev/video0)" but I can't select it. I'm not sure what to do about this or how to fix it? I've searched around the internet and read the ubuntu documentation on webcams but really haven't had any luck for my specific webcam. I would just like the webcam to be detected by ubuntu 9.10, to work properly in skype, and work in cheese so I can record video's.
