Not responding web camera
Im using the built-in web camera. Whenever i try to connect, i get an error message saying that im not responding. What does that mean and how do i get rid of it?
trying to connect to what? Can you provide any more specifics? For the most part, the iSight camera is integrated into the applications so there is no need "to connect" to anything. Have you verified that the iSight is working properly? Try opening Photobooth and see how that goes.

Skype not recognising web camera
I have tried everything to get skype to recognise my web cam again. It used to work fine in a previous version of skype but now nothing seems to work. I have tried reverting back to an earlier version and only get the message "page not found". Skype does recognise the microphone in my camera so I am able to do NO VIDEO calls, but I have seen sooooooo many complaints about this problem with sooooo many ideas from people trying to help and NOTHING works. The suggestion that going back to an earlier version is STUPID. You tell me I have to go back in time to fix YOUR **bleep**up. All I want to do is use Skype free to call video like I used to be able to do. Why does this program recognise the mic in my camera and NOT the camera.......... My suggestion is that Skype should be promoting OTHER free to call programs from other companies, as they dont seem to care about what caused this problem to happen to so many people, and seem uninterested in fixing the problem.. I am running Windows 7 on a desktop and laptop. If anyone can help please email me at [Mod edit: Please do not include personal/private information when making a public post. Thanks!] and I live in New Zealand.

Hey,
I have an identical problem and nothing seems to work. All the settings are fine. Did they ever get back to you? Did it get fixed?
Thanks a lot,
Lennia
Please, run the DirectX diagnostics tool.
Go to Windows Start and in the Run box type dxdiag.exe and press the OK button. This will start the DirectX diagnostics program. Run this diagnostics and save the results to a file. Please, attach this file to your post.

Why JMF can not detect web cam in my net beans IDE?
Hi All,
I am newbie to JMF.
Install JMF in my window 7 system.
JMF can not detact webcam in netbeans IDE 6.8.
But JMStudio is detact available my camera.
CaptureDeviceManager.getDeviceList(null) is return null value.
how to over come this issue...You probably didn't add JMF.jar to your project library folder.

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 )

Lumia 920 seldom does not respond while in sleep m...
Hi,
I encountered the same issue along with another abnormal condition too. Phone turns into locked state and the screen stops glowing (blank black screen), indicating idle state. It doesn't respond when I press unlock button. Also it does not respond for Camera, and Volume buttons too. But, when I connect it to a PC in that state I am able to browse the phone normally via PC only. Phone still remains buggy. As a work around pressing volume-keys + power key + camera key simultaneously restarts the device and resumes to normal state. However, previous state of phone isn't restored i.e., device starts as it were normally restarted.
Regards,

Sorry, couldn't find any place to post this. It seems that there is, at least on my phone, a semi-reproducible bug that stops the volume control from working.
Steps to reproduce (from clean phone, ie. just freshly booted, no remnant IE tabs):
1. Turn on phone.
2. Open music+videos (Xbox music) app. Play a song that is locally stored on the phone.
3. While the music is still playing, open up an Internet Explorer tab and navigate to youtube (m.youtube.com).
4. Play an HD movie file. I played Peter Jackson's "The Hobbit" preview #9. Your previously playing music will stop playing.
5. After a few seconds, stop the youtube video playback by hitting the Windows button.
6. Go back to the music+videos app. Play a song that is locally stored on the phone.
On times that the bug shows up, the music plays at a fixed volume. Using the volume rocker will cause the volume display to increase and decrease, but the actual volume will not change unless you change the volume to 00/30, at which point the sound will mute. If the bug doesn't show up, repeat steps 3 through 6 until the issue shows up. You don't need to reboot in between attempts.
Interestingly, volume control still works if you go back to the youtube video. The issue shows up when using the loudspeaker as well as when using headphones. If nobody else can reproduce it, we can start trying to figure out if it's certain music file types or something that cause it. Diagnostic information below:
Model: NOKIA Lumia 920 Carrier: AT&T
OS Version: 8.0.9903.10 Firmware revision number: 1232.2109.1242.1001 Hardware revision number: 1.0.0.0 Radio software version: 1.0.202041.3 Chip SOC version: 8960
Thank you,
Omkar KandarpaI've had the same problem. The screen won't blank during a call (like the proximity sensor isn't detecting my face/finger/hand). I keep hanging up on people with my ear. I've taken to locking my screen before putting it to my ear but anytime I get another call / text / voicemail / calendar notification / alarm while i'm on the phone (which happens a lot still) it lights the screen up again and makes it where i'm able to hang up with my ear.
I've factory reset, and had the phone replaced TWICE already. I'm on my 3rd Lumia 920 (and they all have the same issue!) This didn't happen until the most recent firmware update...so I think it was a problem created when they were trying to fix the other proximity sensor issue where the screen stayed on black all the time during a call.
Rebooting does fix the problem temporarily, but it always comes back. I'm tired of hanging up on people and hoping for a new model device from AT&T but they're giving me **bleep** at the moment.
TLDR: Factory reset, replacement devices don't fix the problem. It's a firmware bug. I'm on my 3rd 920 with the same issue. Extraordinarily frustrating. -
hi, my firefox and safari are both having difficulty loading certain parts of web pages. previous to this my firefox would freeze and state that a script was not responding. i would stop the script and reload the page and everything would be fine. now though the pages just load very very slowly or load leaving out certain pictures and video content. i've tried clearing my cache's and cookies, resetting my browser etc, but it seems like its a system issue as both safari and firefox are having issues. i've run Avast to screen for malware and it came up empty. any suggestions?
10.4.8's been a pain for Networking... not sure of all the reasons though, or whether all the complaints might not be MS working around Bugs/Non-compliance, but at this point I think you should get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, boot holding down CMD+s, then when the prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
Fixes a lot of problems, and besides, if your Mac ever gets to the point it won't Boot... this is a life saver!
After you run that... let's see where we are.

I'VE COME TO THIS SITE AND DOWNLOADED THE WEBCAM UPDATE POSTED AUGUST OF LAST YEAR, TO NO AVAIL, NOTHING.
I HAVE VERIFIED THROUGH THE DEVICE MANAGER IT'S INSTALLED AND ACCORDING TO IT THE DEVICE IS WORKING PROPERLY. SKYPE NOR FACEBOOK CAN FIND IT. WHEN I OPEN THE TOSHIBA APPLICATION, THE PRETTY BLUE LIGHT ON TOP OF THE SCREEN COMES ON, THE VIEW BOX OPENS AND ITS PITCH BLACK.
ANY HELP WOULD BE GREATLY APPRECIATED AS THIS IS THE 3RD TOSHIBA IN A ROW I'VE BOUGHT DONE BASIC OPS ON AND THEY STOP OPERATING DEVICES I'M NOT USING. THIS ONE IS IN FACT A FREE REPLACEMENT OF THE LAST ONE THAT BURNT UP AS THE FAN COULDN'T KEEP IT COOL ENOUGH. LIL FRUSTRATED SORRY. THANKS AND HOPE SOMEONE CAN HELP ME FROM HAVING TO GO 2 MONTHS WITHOUT MY COMPUTER AGAIN WHILE THEY SEND IT AWAY TO BE WORKED ON.
CHUCK YAGERSatellite L505D-GS6000
Perhaps you mean you have the Satellite L505D-GS6000? Let's try a reinstall of the main base drivers, then the webcam driver/app, one more time. Download and install these drivers in this order:
AMD/ATI Display Driver for Windows 7 (32/64) v8.634.1
Realtek Audio Driver for Windows 7 (32/64)(v6.0.1.5904)
Toshiba Web Camera Application for Windows XP/7 (32/64)(v1.1.1.6)
Then try the webcam again. Please let us know if it works, or if you get any error messages trying the above reinstalls. Good luck

OK...here is doc, what will help you will basic t/s for the issue....http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c02452221
If the above does not help, What I would like to know is if the issue is with multiple application? What happens when you try and use the webcam using those applications....

My web cam is not working no video
Hi ,
My web cam on my hp laptop G72_257CL is not working.Please help me.just pry (pull) up the frame around the top and sides. You do not need to pry out the bottom of the frame. Use your
fingernails under the inside edge of the frame, they have some double sided tape, so it might be a little tough to pry. Pry it
slowly so the tape can separate on its own. Don't force it quickly or you might damage it. Make sure you're not prying the
silver metal frame of the lcd screen, only the black plastic frame. There are some plastic hooks that will make a snap
sound when you pry the frame out, it'll take some force, so don't be afraid if you hear the snap sounds, it should be able
to snap back together if you did it correctly, otherwise you might have to use some tape to tape the frame back,
Once you've pryed out the top of the frame and have access to the webcam module, you
should see the cable going into it from the bottom, push the cable into the webcam, then see if the problem is solved,
the cable most likely just came loose. If that solved the problem, I suggest using something you can remove, like hot
glue to hold it together, just in case the webcam really needs to be replaced, you can melt the glue off and swap it out.
webcam itself somehow got damaged?, which is very unlikely
THANKS
