Not able to recognize any video/audio devices using jmf and java soun

Hi ,
I need one help from your side.
Here I am expecting some clarifications from you. Before that let you my environement.
My working environment :
Eclipse tool and added jmf jar to my project I did not do any thing more.
If any thing I need to do just let me know. My target platform is MAC & UBUNTU.
Please bare with my questions.
1) I am not able to recognize any video/audio devices using jmf and java sound APIs on My system.
( I checked with the app mentioned in the http://www.java-forums.org/new-java/11201-jmf-cannot-connect-device.html )
Do we need any administrives rights for our working PC.
What is the procedure/ setup I need to follow from a java application to enable particular audio/video device since I dont about end-user system setup right.
If possible send some sample code to recognize /r detect audio device ( voice input ). It should run on both MAC and UBUNTU.
2) I run the one sample audio recording application of this link (http://www.jsresources.org/examples/SimpleAudioRecorder.java.html) which is provided by YOU.
I got output audio file and able to hear voice on UBUNTU system but not able to hear voice on MAC system.
I heared that default line in ( audio setup of the sys) is wont take any voice data on MAC.Why I made this stmt means we are getting false when using isSupported methods of JAVA SOUND API.
( like for TragetdataLine ...i,e, all ports are getting false)
I have one sample audio recording app implemented by QUICKTIME API. In this case also he taking audio ftom device only using quicetime API.
With that we are able to record and hear audio ( voice input --> not line in , external device we added some thing like SSB...)
3) In case of Video capturing DataSource, Streams are implemented by PullBufferDataSource , PullBufferStream intefaces used.
In case of Audio capturing DataSource, Streams are implemented by PushBufferDataSource, PushBufferStream intefaces used.
Can you explain the reasons ? I gone through API but i am not clear.
HOPE I WILL BE CLARIFIED EVERY THING FROM YOU.
Thanks

a java streaming quotes platform is launched.
Is there any way (winsock,API,etc...) to capture the data offered by the java platform?
Thanks

In Applescript, when you compile the code, the app must be running. If it's not, then it will start.
When you run the script, InD doesn't have to be started first. You could have some Finder actions happen, then InD starts at the needed time when it's actions occur. You can have an if/then statement that only requests InD to do an action only if other circumstances are met. You do not even need to tell application InD to launch, just the first tell app statement will do it.
I do not know how things work in Javasc or VB.

Image capture from avi vfw device can't find video modes

Hello
Here my issu, i have implemented image capture from a video device using jmf 2.1.1e performancepack, using a webcam everything is fine but when i use the video capture source i want to use i can only work with format 720x480 pal and i require 720x576 pal.
jmf seem not to reconize video format from this source, but the video is correcty displayed and image correctly captured. I'm surprised it is half working:decoding&render is ok to but not format choice.
I have check it is not because i'm in ntsc mode (ntsc is 720x480) because my analogic source is pal and color are correct (if with device software i change to ntsc mode i have a black&with but using jmf i'm in color so i'm in pal mode)
Difference bettween the webcam and my device is that my device is an avi encoder so in jmf webcam is javax.media.format.YUVFormat and my device com.sun.media.format.AviVideoFormat
i have tried many thing:
install codec pack (divx6, another codec pack)
try to use Fobs4JMF
register in JMStudio IBMdecoder, jffmpeg
Tanks for any help
the device support many configuration UYVY 235x288 352x576 .... 720x576 but JMF offer only 1 video mode for this device.
here in jmf my capture device info:
Name = vfw:Microsoft WDM Image Capture (Win32):0

I have multiple devices backed up to the same computer each with different data. how do i keep them from syncing all data when i back up or transfer stuff from the computer to a device?

i have multiple devices backed up to the same computer each with different data. how do i keep them from syncing all data when i back up or transfer stuff from the computer to a device? one is an iphone 6 and the others are ipad mini first gens, each ipad has 64gb and the iphone has 128, need to keep the data seperate as they are not all mine

Itunes content and pics are NOT part of the backup that itunes performs.
Backing up, updating, and restoring iPad, iPod touch, and iPhone software
You should transfer any purchases from iphone regularly: File>Transfer Purchases , if they fail to be transferred when you sync.
You buy one and only one download. It is your responsibility to move/copy/backup your purchases.
You can try contacting itunes support and asking for an exception, but they are under no obligation to allow.

Welcome to the Apple community.
Only one of your libraries needs to use your iTunes Store Apple ID for home sharing. Your other computers can use their own ID for iTunes, so long as they use the same ID as all of the devices on the network for home sharing.

How do I deactivate all the activations of my PocketBook device from my digital ID

I have a reader PocketBook IQ701. When I started to move borrowed books tro the device, I moved the ACSM file to the device directly and then opened the file on the device. I was asked to enter ID, and authorization was OK, but the book was not readable. I had to reboot the device, to start over. I did this or similare a couple of times before I got the message "E_ACT_TOO_MANY_ACTIVATIONS". Then I found out to start (the right way) from the PC with digital editions, but when I tried to authorize the device, I again got the message "E_ACT_TOO_MANY_ACTIVATIONS ...". How do I deactivate all the activations of my PocketBook device from my ID.
I have used another email-adress to create a new Digital ID, and used this to make it work, but I would rather use my own email adress, which I also use with my smartphone and the Bluefire reader.

Digital Editions help people are supposed to be able to reset your
counters. However, you have to be persistent - this is NOT a problem that
will be resolved if you buy HELP time because the product is free. And
most of the tech's I've talked to won't do anything because they've been
set up to do product support for those Adobe products that you pay money
for.
Be persistent.....

How do I stop all of my devices from ringing when a call comes in

How do I stop all of my devices from ringing when a call comes in

Use a different iCloud account on each device.
Don't use iCloud at all.
Disable Bluetooth.
Don't connect to the same wi-fi network on all the devices.
Go to Settings > FaceTime and turn it off.
Go to Settings > FaceTime on the devices and disable 'iPhone Cellular Calls'.
Any of these will work, but the last one is probably best.

Up until the ios7 upgrade I could track all our family's devices from my 3GS, now since upgrading on the iPhone 4S and 5 I can't track them as they come up as 'offline'! And inactive on my icloud id added on the devices!! Please advise.

Up until the ios7 upgrade I could track all our family's devices from my 3GS, now since upgrading to ios7 on the iPhone 4S and 5 I can't track them as they come up as 'offline'! And inactive on my icloud id that added on the devices!! Because I. can't upgrade to ios7 on my 3GS is that why, or do I need to do something else on each device?

It's possible that installing iOS7 on the other devices made the setting to the default for "Find My Friends". The default is off/disabled. Thus they are off line.
Double check their settings for that feature.

Deleted all Java-related files from system

Hello there, community!
This issue will make me look like a dummy, but here it goes. Basically it is what I did yesterday, I erased all Java-related files from my computer for hideous reasons, now before considering a reinstall, I'd like to know whether there is a solution to this problem. My recovery partition still has Mavericks installed, which is weird, seeing as I am on Yosemite already.
Basically most apps won't start, and that includes Finder, App Store and every other major app/resource I might need to use for a recovery.
I tried to re-download Java from Oracle website and JDK, but .dmg files won't run either.
I'm trying to look for as many solutions as possible before I do a recovery, because again, I don't have a Time Machine, and hope there will be a solution as I have lots of work to finish.
Any type of help will be welcome!
Mid-2011 iMac 21.5, Mavericks 10.10.1

Hello EdNKh,
Welcome to the Apple Support Communities!
I understand that you are trying to reinstall Java but cannot get the .dmg to run. With the information you provided in your post, I would suggest using the information in the attached article to reinstall OS X Yosemite. Reinstalling with this information will keep your files and settings intact.
OS X Yosemite: Reinstall OS X
Have a great day,

The Apple ID and Password that was Originally used to Activate the iDevice is required.
If you cannot get this information from the seller
Removing a device from a previous owner’s account
You need to return the Device for a refund, as you will not be able to re-activate it.

WHen I put music onto my devices I will have some songs that will play, while others will be grey and can not be played....also I find that when I purchase an album from iTunes all songs from the album will not be downloaded...

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Unsync all music and resync
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

If necessary

Downloading past purchases from the App Store, iBookstore, and iTunes Store
