Please Help in this webcam problem,Its Urgent

Hi,
I have a final yr project by which I can see the picture(whenever I want) of a webcam of a Home PC from my mobile device.
For that I have to write a Java program which will capture the picture from webcam and changed the file format to PNG and then saved it to some directory.Whenever I will run the Java program it will automatically save a picture in the directory and it will do continuously after 5 sec and overwrite the older picture.
Can anyone help me with the code or some sorts of code.
Please help me as it is quite urgent.

Sorry, this forum is for solving specific problems, not for begging for help. If you have a specific problem you need help with, then ask...but I doubt anyone is going to put in the time to help you with a project you havn't put in the time to have specific problems with.

Dv6-1030us Webcam Problem

I have a dv6-1030us computer and it seems since I installed Vista Service Pack 2 the built in webcam works intermittently. (I noticed the problem too long after I installed SP2, so I have no easy route back to SP1) Most of the time it simply doesn't work; when you open the HP MediaSmart webcam program, your hear the sound of a usb device unplugging and get an alert that the "Connection to the video device was lost". If you check device manager the webcam still shows up as there and I don't see anything else missing.
Occasionally - and I have not been able to reproduce a chain of actions that are repeatable to help solve the problem - the camera does work. Probably less than 5% of the time. I have called customer service and they said other people are reporting a similar problem, but I have yet to see anyone post. I am wondering if I simply have a hardware failure with the camera. I have updated all drivers and have the latest bios version f.24. Any suggestions?

I've had this laptop for two years without a webcam problem. Upgraded from Vista to Windows 7. My webcam stopped working. If I go into HP MediaSmart Webcam it shows an image for a few seconds and then it loses its connection. I can't get it to work in the latest version of Skype anymore. It's not even an option to choose from. The only option is a Cyberlink webcam filter that I've never noticed as an option before. Any suggestions?

Hp notebook G62-b25SA Webcam problem.

G62-b25SA
XR524EA#ABU
Windows 7, 64 bit.
I have never been able to use my built-in webcam. I have installed the latest Youcam drivers and still an error message - "No webcam detected, if you are using an integrated camera make sure that it is turned on".
I have also followed instructions on this website - I have gone to Device manager and "scan for hardware changes" but I never get an icon for "imaging" hardware.
I know the computer has the hardware as my parents have an IDENTICAL computer - bought from the same shop at the same time!
Please help!

Hi
You have a couple of options as I see it please try these steps might help you to fix the issue.
Fixing Webcam Problems in Windows
Testing a Webcam With MediaSmart in Windows
If both these links does not work then you might have to call HP Techincal support and get the part replaced.
If your notebook is still under warranty, contact HP and arrange to have the drive replaced.
If you are out of warranty and would like a guide on replacing the Hard Drive yourself, please let me know.
Let us know how it goes!

Unable to capture video from webcam in JMF in xlet

hi
I am unable to capture video from webcam in an Xlet. I am using Xletview to run Xlet. The method CaptureDeviceManager.getDeviceList(vidformat) returns empty array. Which videoformat should I use and why do I get empty array?
Thanks
Rajesh

MHP and OCAP only use JMF 1.0, which does not include support for capturing video. You will not be able to do this in any current MHP/OCAP imlementation that I know of.

nowadays have many user have problem with update to ios7 and need active with apple id maybe in the future in order escape from these problems must be stop use these products else. Because of simple user don't know about this technology and sometime just hear from other user that it 's difficult to use then force they change phone that use to handle to another.

It is a feature to discourage the theft of iPhones by making them useless if resold. It's not going anywhere. It's simple: just don't buy a phone until you make sure that the activation lock has been disabled.

Hello I suffer from a problem with your MacBook There is a black line in screen

Hello
I suffer from a problem with your MacBook
There is a black line in screen
http://i48.tinypic.com/35apzz8.png

Is the line always present? If you boot up the MacBook holding down the option key during startup so that you get to the startup manager, is the line still there?
If so you have a hardware issue and it needs to be repaired. Contact Apple using their Express Lane if you live in a country where that is available, or call the appropriate phone number on this page if not. You can also take the MacBook in to an Apple store or service provider.
Best of luck.

How to Display a image from WebCam in the Forms 10.1.2.0.2!

Hi Friends!
I'm using a Forms 10.1.2.0.2 and i need to display of someway a image from webcam in some item inside the Forms!
This is possible?
I saw an explanation in http://www.orafaq.com/forum/t/89431/67467/ but it works only for a Forms 6.0!
Somebody can Help me?

As Jan mentioned, there is no way to display webcam video in Forms unless you create a Java Bean which can be incorporated into your form. As Pauli mentioned, if your webcam software is viewable via a browser, you can use WEB.SHOW_DOCUMENT to display a browser window with the content, however you will not be able to put this content in the form using the method.
A good starting place would be Google. Look for a java bean or applet which can operate a web cam.

Solved restarting from sleep problem myself.

Let me tell my case. i have had never problem on restart from sleep.
because i always use my new octacore 2.8 with TIGER.
there is some two major reason.
1, performance is better than Leopard. Leopard is heavier when , mouse movement, some 3d application's rendering speed, and even drag n drop folder etc.
2, some application i use still run well on Tiger. apple did not consider compatibility with older application at all.
Because apple did not want user install tiger on new 2008 macpro, i must put out pre-installed tiger HDD from another mac and put into new mac. and it works well. any sleep from restart problem at all. problem is graphic card. i have 2600HD and 1900 XT. if i connect 2600HD, i can't accelerate GPU power in Tiger. it works only in Leopard.and even in sleep mode, but graphic cards fan always run.
but when i boot use bootcamp to XP, i must connect to 2600HD. 1900XT did not display screen at all. like this i use 2 graphic card.
I can't sure this problem due to hardware or OS problem, but obvious thing is tiger have never the problem. little problem is card's fan always run even in sleep mode. hope my case could be a clue.

New firmware has come. and positive reply posting. good job
i wonder if this new firmware destroy booting Tiger feature or not.
i must use tiger now. hope apple do not disable tiger running in new macpro.
any comment will be thanks.

Record from webcam to f4v on FMS

I'm trying to build / modify an application to record from webcam and microphone, in a web browser and save it to an FMS 5.4.2 server to stream via web and iOS
recording as a flv file works fine and it plays back just fine in firefox / any browser
I can steam f4v files over http as filename.f4v.m3u8 and that works fine with the samples that come with FMS from my record folder (/opt/adobe/fms/applications/record/streams/)
My flash web application can record to the FMS server, the file it records has the .f4v file extension, has content (i see the file size), and has time in quicktime (4 or 5 seconds - just a test) but it doesn't play - the screen is black and never starts.
I know i'm right on the edge of figuring this out, I just don't know what I'm missing or whats wrong (i'm a php programmer, not action script)
any ideas ?

Hi,
Thanks for the details
First, the quality of the feed we get to the flash player and FMS is highly limited by the capabilities of the webcam that the users have beyond which we cannot improve the quality.
Next, flash player can encode good quality and hence you should probably find more stuff related to how best you can ingest video from a webcam on to the flash player.
- Does recording from server side with asc script will increase the quality ?
No, FMS does not do any type of transcoding/re-encoding stuff. All it does is to 'transmit' and in your case, to flush bits to the disk. So, unless FMS recieves 'Quality', it cannot do much.
- what configurations files on the server can i adjust to increase the recording quality ?
From above, it flows that, there are no configurations on the server that can make your quality grow. The configurations are more to do with delivery. It can be tweaked to improve streaming, reduce latency, quick start and more.
- is there a way to cache locally the stream if the bandwith is not high enough, and when the user stops recording, upload it to the server (it doesn't have to be live or broadcast).
I don't think flash player can do this.
Thank you !
