Problems initializing webcam device with JMF

Hello,
JMStudio works fine on first try. Webcam stream is captured and displayed.
If I start JMStudio a second time, an error occurs "Couldn't initialize Webcam Device".
After rebooting my laptop it works again once.
Same errors occur with all example scripts using webcam device.
I'm using Windows Vista Home Premium 32Bit and a Vega USB 2.0 Camera (integrated in my laptop)
Thank you in advance.

Why wouldn't it work correctly the first time if JMF isn't releasing it correctly?
It seems the webcam connection isn't executed correctly on exit, so it can't connect again the second time.Connection isn't executed correctly on exit? You mean JMF isn't releasing your web cam, correctly, when it's done with it... I feel like someone just said that...
I just installed JMF today and JMRegistry recognizes my webcam and And the fact you only installed it today rules out the possibility than something went wrong during installation...why?
unfortunately I couldn't find drivers for the webcamWhen I suggested that you make sure you're using the correct drivers for the web cam, just to be clear, I was referencing the drivers for your operating system, not anything to do with JMF.
If you're using the incorrect drivers in the OS, whenever JMF sends out a "release the web cam" command, incorrect OS drivers may not be able to release it correctly.
All sarcasm aside...you should try reinstalling JMF, to make sure nothing funky happened during the installation...and you should make sure that Windows is using the latest, best, most accurate drivers for your web cam, to make sure that you're not using a flat-head screwdriver to try to screw in a Phillips head screw...

  • Problems connecting IOS devices with new Comcast wireless cable modem?

    Just installed a new cable modem from Comcast, it is their new high speed unit manufactured by Cisco. of the three IOS devices I've tried, all running currently the OS , are having problems connecting with  the error "Unable to join the network " Home-XXXX" if you keep asking it may connect but I have to be persistant.  My Devices are iPad 4 g Retna with 30pin connection, an iTouch ,latest model with camers, and current iPad mini. is it me or the modem?

    You have probably already solved this issue, but I would hide the comcast wifi network (dont broadcast ssid) and make the password very hard. Make sure that put it on channel that does not conflict with your Airport Extream.
    Connect the Comcast modem/router to the airport extream's wan port with an ethernet cable.
    Comcast usually ships the DHCP enabled. Use the comcast DHCP server for your airport.
    Configure the airport extream to "create a network" set the network to "bridge mode".
    Name your network, broadcast the ssid all on the airport. Now all your devices will connect everytime. Use can use the Comcast "private" wireless network for maintenance, etc.
    Just some thoughts... good luck

  • Trouble with detectin IDS Eagle capture device with JMF

    Hi
    I'm having trouble detecting my capture card (IDS Eagle model). Is anyone else having the same problem? I tried using the JMStudio tool but the only capture devices detected are the audio ones.
    I have installed the WDM driver for this card but jmf doesn't detect it.
    Any help will be appreciated. Thank yoU!

    Hello Tania,
    I think if you look at the source code for AVTransmit2.java, which can be downloaded, this will help you. Make sure you use javasound://8000 as one of the parameters when creating the AVTransmit2 object.

  • The problem about the interMedia with JMF

    I have done the following things:
    1. Add jmfordim.jar into my client computer's CLASSPATH
    2. Using JMFRegistry, Add "oracle.ord" into both my client's "protocol Prefix List" and "Content Prefix List" in PackageManager tab, commit on both.
    My computer is a client, and the Oracle 9i database and the intermedia are installed on another server with the service name "CAO". I use the JMStudio on my computer.
    But when I use the URL :"im://oci8/CAO/scott:tiger/SELECT t.aud.getcontent(), t.aud.getmimetype() FROM TAUD t WHERE n = 1 " and add into the JMStudio's OpenURL,
    it can't work correctly.
    Would you please tell me the reason? Thank you very much!

    Can you post the error message? Or print out a java stack dump with the exception text?
    There can be problems in different areas, without the error information, I cannot hope to tell you why it does not work. Perhaps you don't have the orcale JDBC driver in your path?

  • Found problems pairing bluetooh devices with my iphone 6 plus

    Cannot pair my car radio and my headphones via bluetooth with my nrew iphone 6 plus.
    They paired worked perfectly with iphone 5.

    Turn off the vehicle. Then reset the iPhone. Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot. After the phone restarts follow the procedure outlined in your car's manual to put the car radio in pairing mode.

  • Problem initiate AV chat with other ichat (both windows & Mac)..

    I'm able to accept ichat AV from both windows (aim 5.9) and from os x user; however, whenever I initiate ichat connection to either mac or windows user, I keep getting the error:
    "Failed to start video chat because user did not respond", but the user did respond..
    I'm able to "accept" AV chat from other windows/mac user without any problem.
    I've done the following so far, turn off firwall on my imac.. configure port forwarding on my 2wire router following the apple support article (tho, my windows machine is also behind this firewall and I was not able to initiate chat with the windows box).
    I saw a previous discussion about this problem someone else has and the suggestion was to reboot the machine.. which I did that and it still didn't help. Oh, I did update to the most recent ichat program as well.
    Any suggestion is greatly appreciated. Thank you.

    Hi Ralph,
    I tried chatting with RjinWI last night and I was able to initiate an AV ichat with him (mac version) bu† I was not able to initaite AV ichat with RjinWI PC, I was no† able to initiate another AV ichat with another Mac user on the list (unfortunately, I forgot who that was) but I was able to initiate with ichatavtesting. My Buddies defintely can ichat with others and he may also initiate a chat to my imac.
    Since then, I have upgraded my firmware which didn't help.. but a small break through was that after I reboot my imac (without having any program running on the imac), I started my ichat and I was then able to initiate AV chat with RjinWI PC.. but a few hours later (after I open my thunderbird, firefox).. I was having problem initiating AV chat with RjinWI PC again... pretty strange?
    Since then, I restarted my imac again and now it's working again.. and I have both firefox and thunderbird open.. and AV chat with RjinWI PC is still working.
    At least with this info, the problem might not be with my router afterall? I wonder if there is any program that might be blocking the port(s) or using the same ports (I read about the VOIP program issue with ichat, which I'm not using)? So far I have started opening one program at a time and see if I may duplicate the problem (at first I thought it might have been one of the widget program.. "doppler radar" and "live web cam" but I have disable and re-enabled them.. and yet my ichat is still functioning as we speak). If you have any other idea, please let me know. If I am able to gather more info.. I'll be sure to post more info. Thanks again.

  • Detection problem on HP webcam with JMF

    Hi,
    I'm trying NyARtoolkit and I need to use the video stream of my HP's webcam encrusted above the screen of my laptop (a HP Pavillon tx 2670ef)
    After the installation of JMF, I lunch JMStudio and I manage tu detect my webcam in : File->Preferences->Capture Devices->detect capture devices.
    Then i close the windows and i do File->Capture...->I enable "use video device" and unable "use audio device" then i click on "OK" but aftewards i have an error message saying that JMF couldn't initialize the capture device...
    2 students with me have the same pb...
    I made some researches about this issue and i found this post
    http://72.5.124.102/thread.jspa?messageID=10177842
    Afterwards I've installed ManyCam and i managed to get a video capture from the virtual webcam simulated with ManyCam.
    In fact, when i click on detect capture devices in JMStudio, a windows appears and i can choose "ManyCam Virtual Webcam" instead of "HP webcam".
    Moreover, in the options before capturing video, the encoding is in RVB instead of YUV before with the "HP webcam".
    But when i run my program i have this error :
    java.lang.ArrayIndexOutOfBoundsException: 0 >= 0
         at java.util.Vector.elementAt(Unknown Source)
         at jp.nyatla.nyartoolkit.jmf.utils.JmfCaptureDeviceList.getDevice(JmfCaptureDeviceList.java:80)

         at J3DJME.NyARJava3D.main(NyARJava3D.java:76)
    I tried many other things (Quicktime with QTcap... but i didn't managed to solve this pb yet)
    Coud you help to use my webcam with jmf ?

    You probably want to remove the crust from your web cam if you expect it to work. Most things that are encrusted aren't in the best of shape...
    JMF connects to web cameras by wrapping around native interfaces. If the JMStudio isn't able to use your web cam, it could mean a number of things...your web cam isn't compliant with the version of the interfaces (VFW and DirectShow, I believe) that JMF is wrapping around, the web cam doesn't output any formats JMF can use, etc.
    But if JMStudio can't use your web cam sucessfully, 99% of the time that means your web cam isn't going to work with JMF... unless you want to code support for it yourself.

    Hi,
    I am trying to Set/Get Volume level of Input device which has only single channel but no master channel, then it fails to retrieve the kAudioDevicePropertyPreferredChannelsForStereo and intermittently kAudioDevicePropertyVolumeScalar for each channel. But this works well for Output device.
    So is there any difference in setting/getting the volume of input channels?
    I am pasting the downloadable link to sample.

    That works but the the game will not be in full screen, it will have an empty strip at the bottom.
    I actually found out what's the problem. I traced the stageWidth and stageHeight during resizing event. I found out that when it first resized, the stage width and height were the size with the notification bar. So when I pass the stage into startling, myStarling = new Starling(Game,stage), the stage is in the wrong size. For some reason, I can only get the correct stage width and height after the third resizing event.
    So now I need to restart Starling everytime a resizing event happened. It gives me the right result but I am not sure it is a good idea to do that.
    And thanks a lot for your time kglad~I really appriciate your help.

  • How do you get your webcam device name from the JMF registry?

    Ya, I don't know where the JMF registry is.....is there a list somewhere in the API? Is it somewhere in the Windows registry files after installing JMF? I keep hearing you need to do this when creating a webcam application but never seen it explained anywhere.

    The registry is a file located in the lib directory under the installation of Java Media Framework, called jmf.properties.
    You can edit it with the jmfregistry application provided with JMF, or using the proper classes such as the CaptureDeviceManager.

  • How to get connect with Apple when you have problem in test device limits?

    I have reached my test device limit in August. I have popular app that is very sensitive of being tested super carefully (navigation app for the blind, testers from 20+ countries), so 100 device limit is easily reached. Basically, I can't ship any new versions due to fact that I can't guarantee safety of my users.
    I sent first request how to handle this to Apple in August. Since then I have sent at least 3 new requests. 2 times some person has responded suggesting adding 10 new devices or asking me to delete unneeded away and then list gets reseted after 7 days. I answered "yes please do that" and cleaned the list. Still after several months, I have situation that my device list shows "100 of 100 available devices have been registered." and adding new devices is disabled.
    I had read that this list can be reseted when I renew my dev membership. I did that one month in advance to see if it helps. It didn't and even when old one expired, it didn't help. Maybe I have missed some step, but for that reason I have tried to reach Apple Support. My two latest contacts to Membeship support has this same information about my problem (of problems getting support) and also short description about original problem.
    Have any of you had same kind of problem with Membership Support? When I have contacted Developer support, I have got excellent service.
    How should I continue? Start trying to make phone calls instead of using official contact forms?

    Your problem _is_ the device limit...you repeated your issue, so I'll repeat the quote from Apple:
    Although you may remove a device from your account, it will continue to count against your 100 device limit.
    Please confirm you understand the process now, thanks.

  • Problems of MDIApp.java with cross-platform JMF.
