Monitor and capture at the same time?

Is it possible to view/monitor a video (live from a quickcam) and capture at the same time?
I looked at the solution here:
http://java.sun.com/products/java-media/jmf/2.1.1/solutions/index.html
And found "Video Capture Utility with Monitoring" sample program. However it only allows capture! There is no live display of video viewing while the capture is happening.

Actually, the sample program works once I uncheck Audio.
I do not have any Audio input device, so I guess that is causing the problem.

  • How to connect my MacBook to a monitor and TV at the same time? I have a thunderbolt, what else do I need?

    I have an ASUS monitor and a SONY TV set. I have 2 HDMI cables, one for the TV and one for the monitor. I also have a Thunderbolt for my Mac and I have HDMI Pigtail Switch with 3 ports. For some reason when I connect the Pigtail Switch to the Thunderbolt and the 2 HDMIs to the Pigtail nothing happens. Anyone knows the answer?

    Sounds like you're using a POP mail account.
    You should get an IMAP account. such as the free one you get with iClourd.

  • Can I use DisplayPort (for a monitor) and Thunderbolt at the same time?

    Hi all,
    I have a mid 2011 MacBook Air 13 inch with a single Thunderbolt port.
    I have the Apple Mini DisplayPort to Dual-Link DVI Adapter cable which I am able to use to run a Dell 24 inch monitor - this cable connects to both the DisplayPort/Thunderbolt port and also a USB port on the Air.
    I want to be able to run this Dell monitor, and also run a Thunderbolt hard drive - one with 2 Thunderbolt ports.
    Is this possible?
    Can I connect the DisplayPort part of the cable to the pass-through Thunderbolt port on the hard drive, and then connect the hard drive to the Thunderbolt port on the Air?
    Thanks, for any advice :-)
    I would like to buy the Apple Thunderbolt display (which would solve this issue), but I suspect it will may refreshed soon. So I don't intend to get one until then.
    Thanks :-)

    OK,
    I have tried this myself and it does work.
    Macbook Air - connect to Seagate GoFlex Thunderbolt (Using Thunderbolt cable)
    Seagate Goflex Thunderbolt passthrough to a Dell 24 Inch monitor (using Apple Mini DisplayPort to Dual-Link DVI Adapter cable).
    Both the Seagate GoFlex and the Dell 24 inch monitor work :-)
    I am happy with this result, so I won't need to get a Thunderbolt moniter just yet - I will wait for Gen 2 :-)

  • I'm trying to record audio into my iPad2 using GarageBand and an iRig, but I can't monitor my tracks at the same time as recording, meaning if I lay down a drum track and attempt to record guitar, I can't hear the drums while recording. Thoughts?

    I'm trying to record audio into my iPad2 using GarageBand and an iRig, but I can't monitor my tracks at the same time as recording, meaning if I lay down a drum track and attempt to record guitar, I can't hear the drums while recording. Thoughts?

    Hi, I have this exact same problem. I haven't been using an iRig, just a cheap USB-jack cable. I managed to do this with the first cable I bought, but since it broke I've been unable to find a replacement that allows me to hear the drums while recording. DId you manage to get over this issue? If so I would really like to know how. Thanks and best wishes.

  • Can't get 2 monitors to work at the same time G4 533

    Hello all,
    I have a G4 533 Dual with the stock card in it I think it is a nvidia GeForce 2MX I have a 17 inch clear monitor It is the one that matched it new. I also have a old apple 17 inch display this is the old tan one with the colored apple on the front( I have an adapter to plug this one in). The video card has 2 ports and both monitors will work in their port but if I plug them both in at the same time the clear monitor goes out. If I plug it in first then add the older one the older one wont work. I have restarted and tried all different things the ports all work as do the monitors just not at the same time. I want to be able to see differnt things on both monitors. I also have a 733 with the same 2mx card so swaping them wont help. Can anyone tell me what I need. thanks.

    Hi Sarkis,
    I note that this is now the subject of another thread that you started - it's better to stick with one thread per subject otherwise there's "double handling" involved in answering your issue.
    For what it's worth, the older (none core image) cards that will do extended desktop are:
    Mac Radeon ATI 8500
    Mac Radeon ATI 9000
    Mac GeForce4 Ti
    As a rule of thumb, a card with 64 mB or more will generally be able to do extended desktops.
    If you want core image support, then any card later than the ATI Radeon 9600 will do, with the ATI 9800 probably being the card of choice.
    This has been posted your other thread as well.
    Cheers!

  • Connecting USB and Charger at the same time

    Hello guys, Is there any problem connecting usb and charger at the same time? after that, the Nokia Battery Monitor 2.0 shows 93% after full charge. Any ideia?

    yes, there is a male-female usb extension cable sold on computer store.
    Just pick up the length you need.
    But the price is almost the same with the cheapest 2.0 usb hub (4 port), so you better consider the usb hub one.
    Good Luck.

    OK great info!
    I found 2 possible ethernet to USB adapters:
    By "Plugable":  USB 2.0 to ethernet LAN wired network adapter - seems this will work, but I'll contact Plugable.
    2. Apple USB Ethernet Adapter
    Easily connect your MacBook Air computer to an Ethernet network with the Apple USB Ethernet Adapter. Small and light, it connects to the USB 2.0 port of your MacBook Air and provides an RJ-45 connector that supports 10/100BASE-T performance.  BUT NOT SURE IF THIS WILL WORK ON ANYTHING BUT a MacBook Air…
    One person commented: 
    This little gem used to be the device of choice for adding a second Ethernet interface to a Mac Mini Server and I'd been using one that way for about a year. After doing a software update to 10.6.6 it stopped working. Forewarned is forearmed – it appears that Apple is finally enforcing the MacBook Air system requirement.
    Thanks for any additional comments.

  • How do i start video and audio at the same time in ios

    How do i start video and audio at the same time in ios?
    I have tried a lot of different ways but i cant figure it out?
    I can get the sound and animation (timeline) to start playing.
    There is no problem to start the video and the animation at the same time.
    But i cant get both the video and the audio to start playing when i press a button.
    It works great in OSX and on windows?
    Here is an example:
    // insert code for mouse click here
    // Play an audio track
    sym.$("_1")[0].play();
    // Play a video track
    sym.$("host")[0].play();
    // Play the timeline at a label or specific time. For example:
    // sym.play(500); or sym.play("myLabel");
    sym.play("marker1");

    If the game has sound in it (and possibly even if it doesn't) it may be overriding the Music app and causing it to stop playing - in which case there is nothing that you can do about it.

    Try arming the audio tracks, select one of the tracks, then while holding down the shift key, select the midi track you want to record, arming the "r" on the midi track. Press "record".....

  • Can we use both INSERT and UPDATE at the same time in JDBC Receiver

    Hi All,
    I would like to know is it possible to use both INSERT and UPDATE at the same time in one interface because I have a requirement in which I have to perform both the task.
    user send the file which contains both new and old record and I need to save those in MS SQL database.
    If the record exist then use UPDATE otherwise use INSERT.
    I looked on sdn but didn't find any blog which perform both the things at the same time.
    Interface Requirement
    FILE -
    > PI -
    > JDBC(INSERT & UPDATE)
    I am thinking to use JDBC Lookup but not sure if it good to use for bulk record.
    Can somebody please suggest me something or send me the link of any blog or anything to solve this problem.
    Thanks,

    Hi ,
              If I have understood properly the scenario properly,you are not performing insert and update together. As you posted
    "If the record exist then use UPDATE otherwise use INSERT."
    Thus you are performing either an insert or an update which depends on outcome of a search if the records already exist in database or not. Obviously to search the tables you need " select * from ...  where ...." query. If your query returns some results you proceed with update since this means there are some old records already in database. If your query returns no rows  you proceed with "insert into tablename....." since there are no old records present in database.
      Now perhaps the best method to do the searching, taking a decision to insert or update, and finally insert or update operation is to be done by a stored procedure in MS SQL database.  A stored procedure is a subroutine available to applications accessing a relational database system. Here the application is PI server.   If you need further help on how to write and call stored procedure in MS SQL you can look into these links
    http://www.daniweb.com/web-development/databases/ms-sql/threads/146829
    http://www.sqlteam.com/article/stored-procedures-parameters-inserts-and-updates
    [ This part you can ignore, Since its not sure that you will face this situation
        Still you might face some problems while your scenario runs. Lets consider this scenario, after the stored procedure searches the database it found no rows. Thus you proceed with an insert operation. If your database table is being accessed by multiple applications (or users) other than yours then it is very well possible that after the search operation completed with a null result, an insert/update operation has been performed by some other application with the same primary key. Now when you are trying to insert another row with same primary key you get an error message like "duplicate entry not possible for same primary key value". Thus you need to be careful in this respect. MS SQL has a feature called "exclusive locks ". Look into these links for more details on the subject

        There must be other methods to avoid this problem. But the point is you need to be sure that all access to database for insert/update operations are isolated.

  • Can I use a camera for application in Labview and VBAI at the same time ?

    Dear all,
    I'm trying to save an AVI file with Labview and make an image process with VBAI at the same time, in one machine.
    The error : "Camera already in use" displayed.
    My Camera is a GIGE and I work with Imaqdx. I've test the multicast mode but it only operate with several machines.
    How can I do this ?
    Thank's to help me,
    Yoann B

    I'm not necessarily saying that.  It's been a while since I've used VBAI, so I don't remember all of the capabilities, but if VBAI can do the inspection and recording at the same time, you should be fine.
    The trick is that only one program can access the camera at the same time.  That application reserves the camera, thus making it unavailable to others.

  • My SB Audigy 2 card can't use headset and musicamplifier at the same time

    Hi, i just bought a SB Audigy 2 [D400] and i have downloaded drivers and programs. I run Windows XP SP2.
    The soundcard works fine but it is very very annoying that i physically have to change the jack in the green=line out jack from headset to musicamplifier when i want to use my musicamplifier and change back the jack in the green=line out from musicamplifier to headset when i just want to use the headset/headphones .
    In the shop they told my that i can connect both amplifier and headset at the same time and then with creative software control whether there is sound in the headset or in the amplifier. But i can't simple get it work.
    I tried to use the green to the amplifier and the headset/speakers in the black (line out 2) and then with creative speaker settings softeware choose headphones but still the ampliefier receive the sound and no sound in the headphones. Why? In fact no matter what configuration i try the headphones doesn't work.
    But if i change the jacks so headset is in the green line out then only headset is working and the amplifier doesn't work no matter i put it in sort=line out 2 jack or orange=line out 3 jack.
    Can somebody here tell me if it is possible or not to connect both headset and external amplifier and control by software which to play? and how?
    please help, thx.
    Michael

    If you can have an ASIO compatible music playing system, then it might be possible to have system like you wish when using Creative Audigy 2 card. Since ASIO bypasses Windows Audio System, you can use both 'drivers' (ASIO - WDM/MME/DS) side by side.
    Say you want to play a game (using headset /w mic) and someone other like to listen music at the same time. With ASIO capable system you can output your music for example to "center L/R (stereo) channels" and same time output sounds from other source (using MME/DS/WDM drivers) to normal output channel (Front L/R). Only thing is, you need to set your speakersystem to 4 or 6 (depending which other channel you're using) (and for better 'balance' to adjust "angle" on THX console. You get the THX console by installing Audigy 2 Zs software).
    Try for example http://img332.imageshack.us/img332/463/djs9mo.jpg[/img] width="406" alt="Image Hosted by ImageShack.us" >
    Another option:
    Say you want to play music through external amplifier and play game online with your headset + microphone (eg. others but you listen the music, you play games)
    --> try free http://img332.imageshack.us/img332/4589/tbp7rz.jpg[/img] width="406" alt="Image Hosted by ImageShack.us" >
    If you use ASIO on BeatPort Player you can select L/R individually from the list(s). Same rules as described earlier.
    = You can play from 2 different sources simultaoneusly (ASIO + WDM/MME/DS) to two different outputs without disturbance. The other (WDM/MME/DS) source is set 'automatically' output to (Audigy) "green" port, and the other (ASIO) to "black" or "orange" port (as set).

  • Ipod nano (5th generation) - want to use headphones and charge at the same time

    I have an ipod nano (5th generation).  Do I need a special set of headphones to use the headphone jack and charge the ipod at the same time?

    The iPod nanos have a 30 pin dock connector and a headphone jack. When you charge the iPod you use the dock connector therefore you can use and charge at the same time. You cannot use and charge the iPod shuffle at the same time. You might have the two mixed up.

  • Problem with audio of my notebook. Audio works through pc speakers and earphones at the same time

    Hi all, 
    thanks in advance for your advices.
    I have a problem with my notebook (HP pavilion g6 2305 sl).
    The problem is that when I connect my earphones the audio of my pc don't stop, hence I can hear (music, film, ...) both by earphones and speakers at the same time.
    I tried to install again the latest driver audio, but nothing was changed.
    I tried to use another pair of earphones, but nothing.
    I have noted that if I connect the Jack at my pc, but not until the end, the audio stops from the speakers and goes through the earphones, but only if the jack is not completly inserted in the notebook.
    I read a lot of forum on the web but I'm not able to find a solution for my problem.
    (ps. the problem comes out suddenly, without any signal. I don't have installed any update or new software before the problem's start)

    Right click on speaker icon, lower right screen.
    Choose playback devices.
    Select "speakers and headphones" as your default.
    Disable "communications headphones".
