my web cam wont post pics now?? Have a feeling my daughter did something???
Hello jennifer2000000,
Let's see if we can get your issue resolved. Before I can do that though I'll need to know what computer you have and if it has an internal webcam or an external webcam.
Where are you posting pictures to?
You said now, so am I wrong to assume that it used to work?
What operating system does your computer run?
Does the webcam work for video, but not stills or does video not work as well?
If I have helped you in any way click the Kudos button to say Thanks.

Neither Skype nor test web sites can detect a web camera.
In Control Panel, the integrated camera is reported as functioning properly.
I have updated the integrated driver software, updated DirectX. No change.
Any ideas?Wow that's pretty strange and I'm wondering if it's a bug within Vista.
Out of curiosity, can you download this free video capturing software and this works pretty well in detecting a webcam...

I hope this works for you and I'm totally lost for more additional clues. Is your T400 still under warranty? -
Web cam wont start message says in use by another application
Hello I have recently purchased the Creative LIve!Cam Optia and for some reason the person I am talking to can't see me but I can see them just fine. Every time I go to call someone on Skype I plug in my camera and when the person answers a message pops up in the call tab saying "video error cannot find video source , check to see if it is in use by another application". I have no idea what other application could be using it because I ended up installing most of what came on the installation Cd. I have tried everything from selecting tools on skype then hit options, then I clicked on video settings, then I selected Li've!Cam Optia as my web cam as opposed to selecting default web cam. Then the same message pops up again " Skype did not find preferred video source. Webcam could be in use by another application". The thing that really frustrates me is that sometimes it works perfectly find then it freezes and I try to restart the video and then I loose it completely! PLease help someone I have returned camera prior to this one I don't want to have to do it again for this one. Thank you.
Two choices left - download iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ - and use its rebuild command - this will rebuild yoru library leaving the original untouched so you can go back to it is things do not make yo happy - this will keep your edits, metadata and events but will not keep projects
If that does not work Right click on the iPhoto library and show package contents - look in the masters folder - are your original photos there? If so (and if you have adaquate disk space) duplicate the masters folder and rename the iPhoto library "iPhoto library old" - depress the option key and launch iPhoto ancd create a new library - drag the masters folder to the iPhoto icon in the Dock to import your original photos with your events
This will give you a new library with your originals - edits, projects and metadata changes will not be available
And critically start Time Machine up and leave it running

My mac was updated last week, and I believe it was about camera. After that my QQ was not working alright any more -- the camera within the macbook can no longer be detected. However, when I use FaceTime, the camera is still working. Anyone knows what should I do? Is this a QQ issue or a mac system issue? BTW I also heard that Skype users have similar issues after the recent system updates. And, there is no choice for QQ to "test camera" like Skype does so I cannot really "hook up" the camera through QQ software. Thanks in advance!

A305-S6872 Web Cam Wont turn on
i just replaced my hard drive. did a clean install of w7. everything, and all the drivers work, exept the built in camera. i even downloaded the latest utility from the website, but it only installs the application, not the driver. i don't even see an imaging device on the device manager. when i manually try to add a imaging device, then i can't anywhere on the computer find a driver for the webcam to install it. if any one knows how to fix this problem, plz help.thank you.
p.s. i even checked the regestry. and there is no regestry for the camera at all.You say you did a clean install of 'everything' for Win7. Then you say after that, you downloaded the latest camera utility from the website, which would seem to imply that you did NOT download all the latest drivers, patches and utilities from the Toshiba website, after you updated your Windows 7 installation.
So, if you haven't run all the latest Win7 stuff from the Toshiba site for your computer, then try running these two patch programs first:
Toshiba Registry Patch for Devices and Printers:
http://cdgenp01.csd.toshiba.com/content/support/downloads/patch_device_printer_registry_TC00231900B....
Toshiba Patch Files for Windows 7:
http://cdgenp01.csd.toshiba.com/content/support/downloads/patch_storage_TC00233600A.exe
Then try to run the latest Chicony driver/utility again:
http://cdgenp01.csd.toshiba.com/content/support/downloads/driver_camera_chicony_TC50040800A.exe
Let us know what happens. Good luck!

A305-S6872 Web Cam Wont activate
Can someone help me on this... It says (Webcam is either disabled or has failed Please Check Your Webcam settings)
Go to the control panel and uninstall the camera software, restart and then install it again. Maybe that may work.

I just upgraded to the new Windows 10 and I cant get camera (webcam) to open pops up a screen saying something went wrong make sure your camera is connected and not being used in another app. I checked and its not. Please help..
If System Report / Hardware / USB does not list a camera, you have a hardware problem.
Is the computer still under warranty? If it is take it to an Apple store. Check warranty here:

Even if it is not under warranty, have it checked out at an Apple store. There is no charge for diagnosis. -
Web-cam is not detected yet installed
Hi!
I m doing a program tat can capture movie from available video capturing devices, i hav installed web-cam, but while searching for the devices available(Detecting the device) , it is not identifing the device. And still if i m giving direct the device info to the program("vfj//0")then movie is captured from web-cam.
Program is listed below which is not detecting the web-cam:
public void setMainSource(){
setProcessing(false);
VideoFormat vidformat = new VideoFormat(VideoFormat.YUV);
Vector devices = CaptureDeviceManager.getDeviceList(vidformat);
CaptureDeviceInfo di = null;
if (devices.size() > 0) di = (CaptureDeviceInfo) devices.elementAt(0);
else {
/* I got exception here */
JOptionPane.showMessageDialog(parent,
"Your camera is not connected", "No webcam found", JOptionPane.WARNING_MESSAGE);
return;
try {
ml = di.getLocator();
setMainCamSource(Manager.createDataSource(ml));
} catch (Exception e) {
JOptionPane.showMessageDialog(parent,
"Exception locating media: " + e.getMessage(), "Error", JOptionPane.WARNING_MESSAGE);
return;
Output:
Web cam not found....
So wht shd be the problem , nyone please explain the problem how to overcome from it.
Thank youFirst of all sorry for spelling mistake i write ("vfj//0") rather then "vfw://0"
Yeh! i read your code n your code is also giving the same error
like

Web cams in IE but not firefox
The Hogs Breath Saloon web cam wont run on FireFox4. It runs on the older version no problem.
Duval St web cam has the same problem. I like to keep an eye on Key West so I look at these every day.There are a couple issues here that might be the culprit. One is that the player is hidden using a variety of techniques and Firefox often suppresses hidden content because it can be annoying not to be able to control your experience with media. Another possible issue is that the embed tag doesn't specify a content type. Firefox appears to be guessing anyway, and in my case asking whether to activate the QuickTime plugin, but then nothing plays.
To test what would happen if both of those were addressed, you can run this script using Firefox's Web Console. It grabs the address of the media and creates a new embed that is visible and specifies the content type. Here's how to use it:
Select the following long line of code and copy it:
function reEmbedMpeg(em){var el=document.createElement("embed"); el.setAttribute("type","audio/mpeg"); el.setAttribute("src",em.src); el.setAttribute("style","height:20px;width:200px;position:fixed;right:0;top:0"); document.body.appendChild(el);} reEmbedMpeg(document.querySelector("embed"));
When viewing the problem page, press Ctrl+Shift+k to open the Web Console in the lower part of the tab.
Paste the code next to the caret (>>) on the bottom line and press Enter to run it. A player should appear in the upper left corner, the progress bar should show downloading and then the content should play.
Obviously it's not practical to hack every web page you find, but if this is your site or you would be interesting in contacting the owner, hopefully this post will help in getting this working in Firefox. -
Updated : No question, just example web cam capture code
Hi,
I posted this example a while back, but it had some cosmetic bugs in it.
Here's an updated version.
Quick Start
1. Install JMF 2.1.1e (performance pack version)
( see imports list in source code if you really want to run it using the older version 2.1.1c )
2. You have to set the JMF_HOME or JMFHOME environment variable. Can't remember which one.
"Nearly sure" it's JMF_HOME.
3. Connect your camera
4. run jmfinit ( may need to do a few times until it detects your camera )
When it does, you're in business, and you can try to run the code
5. Run java -cp .;%JMF_HOME%\lib\jmf.jar JWebCam
known issue
Under Java 1.5 / 5 - When capturing a frame, and then resizing that snapshots JFrame, the image did not always scale up and display.
That does work under Java 1.3.1_06 .
Tested on Win98 2nd edition, Java 1.3.1_06, and Creative Web Cam Pro.
Legal stuff in plain english : This code is available for use by everyone, personal or commercial, no need to mention me in licenses or anything. It's just a demo I knocked up for myself. So I am under no obligation to support this. Use it at your own risk.... that implies you can't blame or sue me for anything that goes wrong.
If you like the code, I'd be happy to hear whereabouts you are in the world :-)
Also note : this is the limits of my JMF experience at present.
If you've a separate question, post it to a new topic!
regards,
Owen ( Dublin, Ireland )

Here's a working version.

No Question, just example web cam capture code
Hi,
Since loads of people ask for an example of capturing pics from a web cam, here's one that captures pics, lets you take snapshots, which it displays in another frame. When you shut down the frame it asks if you want to save it to a JPEG.
I'm mainly posting this to spite Eka_Kupkova, who only visits this forum to shamelessly advertise a commercial Twain based package in every single posting on this forum which mentions web cams.
Notes : ( Could be more, read the install docs for JMF )
1. you must download the "performance" version of jmf to capture video.
2. I "think" you need to setup the JMF_HOME environment variable
3. Run the jmfinit program to detect your camera and register it.
I had to run it a couple of times before it worked.
4. I had 2 icons for my toolbar, BtnFormat.jpg and BtnCapture.jpg.
They were just 16 x 16 pixel bitmaps, you can make them up yourself.
5. I assume you've got the webcam working and the driver installed already.
Ps. if you find this useful, then reply back with where you are in the world. I'm in Dublin, Ireland.
cheers,
Owen

I tried and tested this last night, and it runs grand using Ver 2.1.1e.
Tested under Windows 98, using an old Creative GO Camera.
Haven't tried it under Linux, but suspect you'd have to at least change an references to "vfw" to "v4l".
You'll need jmf.jar in your classpath to run it too.
cheers,

inbuilt isight camera is detected in system profiler but no image is being detected only a black screen shows up. I have tried all of the troubleshooting instructions and it still wont work. The iMac im using is OS X 10.6 and was an ex-floor model
Hi,
I would try a Safe Boot first. (This will take longer than a normal Boot and you will need to Restart afterwards).
If it were an older OS I would also suggest going to System Preferences > Displays and making sure the display is set to Millions. (My MacBook Pro does not have this option in Snow Leopard so I did presume Snow Leopard does not have it).
With some laptops there have been some issues with the cable up the back of the screen pulling loose with regular and frequent use of the lid, but this will not apply to you based on your specs. (it does take time to appear and is also somewhat rare). However it seems enough contact with the camera can make it appear in System Profiler and power it on but not give a pic.
If a Safe Boot does not work I would also try a PRAM reset.
Shut down the computer.
Restart it holding down Apple/CMD (or ⌘)+ALT( ⌥)+P+R Keys until you have heard three Start Up Bongs.
This is actually "less" destructive in that it clears less memory items than Safe Boot but they are different enough to warrant trying.
Do you have an older version of iGlasses installed ?
The one for Leopard does not work for Snow Leopard.
Do you have Web Browser open ?
This may point to Google Video Chat Plug-in and Flash Conflict. It would be rare to allow another app to access the camera even if not displayiong a Pic.
(Chrome Installs the Plug-in as does the standalone download).
Knowing what "any application" exactly you are trying might help us pin it down.
Any additional downloaded apps that can use the camera ?
Do you happen to have something balck in front of the camera ?
