Using MediaLocator on Mac for USB WebCam

Is it possible to use MediaLocator to open a webcam on a Mac? Something similar to "vfw://0"? If not, what is the best way to initialize a MediaPlayer with a webcam on a Mac? I.e., what is the mac equivalent of:
"MediaPlayer p = new MediaPlayer();
p.setPlayer(Manager.createRealizedPlayer(new MediaLocator("vfw://0")));"

Why not just write a simple JMF program to iterate through all the devices that JMF detects ?
regards,
Owen
Vector list = CaptureDeviceManager.getDeviceList ( null );
for ( int i=0; i><list.size(); i++ )
     CaptureDeviceInfo devInfo = (CaptureDeviceInfo)list.elementAt ( i );
     name = devInfo.getName();
     System.out.println ("DeviceManager List : " + name );
}

  • Use DAQmxSetDigitalPowerUpStates In VB6 for USB-6501

     How do I use DAQmxSetDigitalPowerUpStates In VB6 for USB-6501
    I am trying to set thre default power on state for all digital lines
    DAQmxErrChk DAQmxSetDigitalPowerUpStates("Dev3", "Dev3/port0/line0:7", DAQmx_Val_Low, 8)
    The above line of code Crashes VB6.0 SP5 VB shuts down as soon as I try to exicute this code

    Hi CUImsch,
    The DAQmxSetDigitalPowerUpStates function takes four arguments: deviceName,
    channelNames, state, and "...".  The "..." indicates
    that you can include additional channelNames and state arguments. The final
    channelNames and state pair must be followed by a NULL argument. For example,
    to set port0 to a default low state use:
        DAQmxSetDigitalPowerUpStates("Dev3",
    "Dev3/port0/line0:7", DAQmx_Val_Low, NULL)
    If you want to set multiple ports with the same function call, include their
    channelNames and state arguments after the first port's arguments and follow it
    with NULL to indicate that you're done listing channels.
        DAQmxSetDigitalPowerUpStates("Dev3",
    "Dev3/port0/line0:7", DAQmx_Val_Low, "Dev3/port1/line0:7",
    DAQmx_Val_Low, NULL)
    The NI-DAQmx C Reference Help contains more information on this function.
    Specifically under the Help Contents: NI-DAQmx C Functions » System
    Configuration » DAQmxSetDigitalPowerUpStates.
    I hope this helps! Let me know if there is anything else I can help with or
    clarify. Have a great day!

  • Can I use FaceTime with an aftermarket USB webcam?

    I'm currently looking at getting a Mac mini and using an aftermarket DVI monitor that doesn't have a webcam. I'd still like to be able to use FaceTime with my Mac so I'm looking at an external USB webcam. I'm just wondering if this will work or if I must have an Apple iSight camera to make FaceTime work? I really don't know much about it as all my other FaceTime devices have built in webcams. If anyone has tried it with success please let me know.

    Hello andywl2000
    As long as you have a web cam internal or external, you will be fine.
    OS X Mountain Lion - Technical Specifications
    http://support.apple.com/kb/SP654
    Photo Booth Requires a FaceTime or iSight camera (built in or external), USB video class (UVC) camera, or FireWire DV camcorder. Backdrop effects when using a DV camcorder require fixed focus, exposure, and white balance.
    FaceTime Video calls require a built-in FaceTime camera, an iSight camera (built in or external), a USB video class (UVC) camera, or a FireWire DV camcorder, and a 128-Kbps upstream and downstream Internet connection. Making HD video calls requires a built-in FaceTime HD camera and a 1-Mbps upstream and downstream Internet connection. Receiving HD video calls requires a supported Intel-based Mac.
    Thanks for using Apple Support Communities.

  • Does any company make a Express Card 34 that can be used in the 17 for USB 3.0

    I want to use an external seagate external USB 3.0.
    Is anyone making one for the Express34 PC Card and if so do you get the extra speed for read and write. 

    Theoretical and acual speeds for all types data connections can differ due to several variables.  I cannot tell you if my eSata connection has ever achieved the theoretical maximum speed because I have never measured it.  However I have compared transfer times against Firewire with large files and it is noticeably faster (at least by 50%+).  Therefore I highly recommend having it if you need to transfer large files from one HDD to another.
    If you have a recent MBP, you already have a Thunderbolt connection.  I do not believe that there will be a Thunderbolt Express Card for older MBPs because they are not configured to accept that technology.
    Ciao.

  • How do I create a disk image for windows 7, using a windows computer for USB bootcamp for mac?

    Hi There, I have just bought a new 2013 iMac.
    Spec: 3.4 GHz intel core i5, 16GB 1600 MHz DDR3 Memory , NVIDIA GeForce GTX 775M 2048 MB Graphics with OS X 10.9.4.
    How can I create a 'disk image' from a windows 7 professional 64bit installation DVD using a windows laptop with windows 7 Operating system on? I want to transfer this 'disk image' (ISO?) to a USB ready for installing windows onto my 2013 iMac using bootcamp?  I want to use bootcamp from a USB as I have no disk drive for the installation DVD on my iMac. I hope all this is clear.
    Thank you. Joe

    Yes, that's correct, at least not directly. You can create a blank disk image, copy the file to the mounted disk image, then burn the image to a CD/DVD.
    Open Disk Utility and select Blank Disk Image from the New menu. Provide a name, Save location, and select the image size from the drop down menu. Leave Encryptions at None and Format as read/write. Click on the Create button.
    After the image file appears the "removable" disk should be automatically mounted. If not double-click on it to mount it. A "removable" disk icon will appear. Drag the file you want to place on the disk image to the "removable" disk icon. The eject the "removable" disk icon. Now select the disk image file in the DU left side list and click on the Burn icon in the DU toolbar. Be sure to have a blank disc ready.
    The above is actually the "long" way to do this. A much easier way is to simply insert a blank CD or DVD into the optical drive. The Finder will pop up a dialog asking what to do. Select the option to mount on the Desktop. You will now see a disc icon on the Desktop. Drag the file you want to burn to the CD/DVD, right-click or CTRL-click on the disc icon and select Burn from the contextual menu.

  • Mac Mini USB Webcam Audio Input

    I purchased a Mac Mini a couple of months ago and set it up with HDMI to HDMI connection to my Samsung TV. I then purchased a Logitech webcam V-UBU48 and connected that to the USB on the Mac Mini. All was fine and I used Skype on this combination with no problems for a couple of weeks, using the webcam as both Audio and Video input device. Sound output was via the TV.
    I then went on leave for a couple of weeks and on return set everything up again as it had been before. This time there is no audio input from the webcam and changing settings in Skype preferences or Midi utility does not seem to have any effect, The webcam is recognised as "Unknown USB Audio Device", but doesnt seem to work. So far as the Mac is concerned the video side recognises it as a Logitech Webcam and still works perfectly. Sound output via the TV is also still fine.
    Since my return the only change that I can identify is the latest Snow Leopard upgrade to 10.6.4
    The other issue is the volume control on the bar at the top of the screen is grayed out and does not function any longer.
    Can anyone help identify the issue here. Thanks in advance

    Thanks for the suggestions. A few hours after posting my issue I switched everything on and all was as before. I could control the audio input level in system preferences and use the webcam for skype calls as before, using it as the audio and video input device.
    Now I have swithched the machine on again and it seems to have reverted back to the same problem as described in my original posting......very frustrating. Nothing registering on the sound input levels in system preferences. Tried restarting several times without success.
    The Midi settings for the "Unknown USB Audio Device" i.e. Webcam are as follows:
    Source Default (Grayed out)
    Format 48000 Hz 1 ch 16 bit
    M Channel volume slider is at the mid point, Value 0.49, dB 18.28, Mute and Thru both unchecked
    I Channel slider grayed out and all else blank.
    Since everything started working again I haven't touched these settings so I assume that they are the same with or without the issue.
    I know issues that occur randomly such as this are least likely to find a solution but further suggestions welcome.

  • Using a different mapping for USB keyboard connected to MacBook

    I just picked up an Apple keyboard and I'm now using my Macbook in clamshell mode, connected to an external monitor, keyboard and mouse. I love the Apple keyboard, but one problem I've run into is that there doesn't seem to be an obvious way to apply a different keyboard mapping to the USB keyboard. For example, I'd love to set Spaces to the F5 key when it's running in clamshell mode, but I still want it set to the F8 key on my MacBook when I'm on the move. Keep in mind I'm using a mid-2007 MacBook, so the keyboard layout isn't the same as new MacBooks and keyboards (http://is.gd/3fuq).
    Does anyone know of any way to load up separate keyboard mappings based on the presence of a USB keyboard? I'd love to do it through the system if possible, but if it's not I'm willing to revert to 3rd party software to handle it if it's solid.
    Thanks in advance!
    Message was edited by: Grant Heaslip

    I work in two languages (Italian and English). The keyboard on my MacBook is English. When not on the road, I plug in an Apple Italian keyboard. Using System Preferences I always keep the input menu quickly available from the menu bar, allowing me to instantly switch from Italian to English.
    I have mapped various F keys using the Mac's own options for Exposé and Dashboard, and then other keys I have mapped with OneKey (opening frequently used applications). OneKey is rock-solid. and I've been using it for several years without the slightest hitch. There are other apps that do similar things but I've found them less reliable.
    With a bit of care, you can get the same mappings to work with both keyboards although of course on the MacBook, you have to press Fn + the F key. On the full size keyboard you only need to press the F key.
    Works well for me. I never open my most important apps by going to the dock. I just hit an F key.

  • Simple question - Can I use a Mini Mac with a webcam to use facetime?

    The quick answer is: yes, you can view your slingbox video on a mac.
    But, there are some considerations about which computer you have and which slingbox you have. Usability and video quality is affected by system speed, network speed and now internet speed even on the local network; as slingbox has made a big push for viewing over the internet via slingbox.com.
    The slingbox for mac download is still available on their site.

  • Slow response for USB Webcam

    Hello - I have a USB 2.0 Webcam attached to my Intel Mac Pro. It's a Logitech QuickCam Pro 9000.
    When I try to "record new movie", and the recording window comes up, I find that the video, while very crisp and clear, has about a 2 second delay and an apparently slow framerate as all motion is very smeared. This comes thru in both the recording window and in the recording itself.
    If I hook my firewire camcorder up and do the same thing, I get nice smooth video with no delays.
    Is there some setting I need to use to have the webcam work properly? Is this a USB vs Firewire thing? If so, does anyone make a firewire webcam?
    Thanks - Craig

    Im not familiar with the Logitech cameras, but have had good results with Labtec pro USB cams.
    Does the Logitech cam come with mac os drivers or are you using some third-party driver?
    I would recommend you to try the Macam drivers http://webcam-osx.sourceforge.net/downloads.html
    And then there is The Unibrain Fire-I firewire cam, but I have no experience with them yet....

  • Two people using the same Mac for tutorials.

    I went through a tutorial with the writer of a program and he was walking me through the program while he was in his home city and state. I believe this 'sharing' was set up in our .Mac accounts.
    I do remember him telling me to get ready to accept a request to use my computer from him. Once he was somehow connected with my computer the on line tutorial was on.
    Could anyone help with what this feature is and a "real good article or tutorial" on how to use it.
    Help is sometimes not too much Help.
    Thanks in advance for any input you may have to offer.

    It's kind of a rough time to learn about .Mac because it's being changed to another service called MobleMe, pretty much at this moment. But there are some pages on Apple's web site that have some information, such as

  • Use Skype on Mac for messages and desktop for call...

    Hi, 
    I'd like to know how to set up my Skype kit.
    I have Skype on my iMac, I use it to send and receive messages.
    I have a Skype phone that I would like to use to make and receive calls.
    I use both regular skype calls and paid calls (I have a Premium account and Skype Number).
    Right now I think the Mac prioritize the calls I receive. I would like the Skype phone to be the priority for receiving calls, is that possible? How both systems, ON at the same time, does interact?
    Thank you!

    The "user agent" (for browsers) is how the receiver determines the senders browser.  It is easily faked to make the receiver "happy".  The only problems I can think of is that now the receiver might be using some flavor of HTML that the sender's browser cannot fully handle resulting in possible display or other problems.

  • Using existing c code for usb-hid communicat​ion in labview

    Hello,
    I want to write a simple temperatrue logger using labview and a external hardware which communicates over usb-hid. The external hardware uses an ATMEL 90USB162 µC and DS18B20 sensors.
    Link to the hardware:
    http://www.diamex.de/dxshop/USB-Temperatur-Sensor-​Tester-fuer-DS18B20
    The source of a a simple command line tool is available (see attachement), which reads out the temperature value of the connected sensors.
    Is it possible to include this c-code in the labview application to simplify the communication?
    Thanks a lot and best regards,

    I'm not that experienced at this personally (in terms of compiling C code into DLLs), but I believe the process you need to go down to call your C code in LabVIEW is to compile the C code into a DLL which you can then call from LabVIEW using a Call Library Function node (or you can try to use the "Import Shared Library" wizard to automatically generate SubVIs).
