Couldn't initialize capture device

I am not able to capture any video from my webcam (Logitech USB Camera). I am working with linux red hat 8, so maybe it's a Linux issue (I got the liux jmf-2.1.1). Anyway, when I try to create a player or processor I get a NoPlayerException, but my webcam is found when i call Vector devices = CaptureDeviceManager.getDeviceList(new RGBFormat()) and I am able to locate the camera with MediaLocator loc = device.getLocator()(Media Location is v4l://0 in case it matters). But when I try to create a player I first get an IOException: Couldn't initialize capture device and a NoPlayerException.
JMStudio is able to initialize the capture device but I just get a black screen. But I can take snapshot images without a problem.
I am actually working on a robotics vision project for my university and i need the camera to plug it on the robot for vision problems.
thanks, muriel

I've had the same problem, I have a Lego camera (basically a quickcam) and it works fine under Linux with the qc-usb driver. Under JMStudio, it is detected, and I can capture from it, and this will work for any user, not just root. When I try to list the devices from my own Java code, however, I don't get any devices. If I run the V4LAuto class (found in the JMStudio source), the camera is detected. Either way, it won't initalize when I try to use it. I've looked through the JMStudio source code to try to see what it does differently so that I can use the device.
On the camera, the light comes on to say that someone is requesting the stream with my own code, but the stream fails to initalize.
I'm running RH9, kernel 2.4.21 (qc-usb won't work on 2.4.20-8). Does anyone know if this has to do with a permission in Java? It shouldn't, but it might.

5.1.4 update breaks HDV capture? Unable to Initialize Capture Device

Problem:
Final Cut Pro cannot capture standard 1080i60 HDV footage from Sony FX1 camcorder. FCP reports "Unable to Initialize Capture Device" when the log and capture window is opened. However, the footage CAN be captured in iMovie (which is interesting, and unacceptable). When HDV>DV downconvert option on camcorder is activated, footage CAN be captured as anamorphic SD, so the camcorder and FW do work.
The problem is occuring on a rock-solid FCP system that I use on a regular basis (mainly for SD editing). It has been approx 2 weeks since I last attempted a HDV capture, the system has been working great with SD footage (still does).
Factors that have changed to my knowledge since HDV capture was last functioning properly:
*Added a new external FW drive into regular usage (a different brand than normally used, no issues with it so far).
*Updated FCP to 5.1.3, and then 5.1.4 when that fix came out. All SD captures and work have been fine so far.
Here's what's interesting...I had a copy of the FCP v5.0.4 .app that I had saved an archive of prior to the crossgrade update. Guess what? I can load it up, and it captures HDV without any problems! With that in mind, this looks like an FCP 5.1.4 issue. But I am at a loss on how to proceed further in troubleshooting. Many thanks in advance for any assistance.

---NOTES---
What I have tried:
*Attempted capture with a different Sony FX1 camcorder.
*Swapped firewire cables and system firewire ports.
*Attempted capture with camera FW chained to an external HDD.
*Unplugged all other external firewire devices from the system.
*Trashed FCP prefs using FCP Rescue 5, created new project using Easy Setup (for HDV).
*Tried different variations of FCP A/V settings, tried all the HDV FW device control presets and the HDV AIC capture preset.
*Per instructions at http://docs.info.apple.com/article.html?artnum=301852 I removed the numbered Quicktime pckg Receipts and re-installed the latest version (7.13). Post-install/reboot, I repaired Disk Prefs and Verified the disk using Disk Util.
*Have also attempted installing QT 7.13 2 and 3 times in a row, also trying disk prefs repair BEFORE the post-install reboot.

I think I figured out this vexing problem. I too was having the same issue. Check to see that your Quicktime is newer than 7.1.2. If it isn't you'll have to upgrade it. I only upgraded to 7.1.6 here because I was afraid of going to a really new version. http://www.apple.com/support/downloads/quicktime716formac.html. After I upgraded my quicktime, I ran software update and the Final Cut Pro 5.1.4 update appeared. I hoipe this helps.

Unable to Initialize Capture Device

Hi,
I am having a problem importing/capturing HDV video from my JVC HD GR 1 getting "Unable to Initialize Capture Device".
I have been able to capture fine up to this point, finicky some times to be sure, but workable, then in the last few weeks it began getting more and more finicky (wouldn't connect to camera, restart and it works fine), until just the other day it wont connect no matter what I do!
Help?
Ask questions if you need clarification.
Camera: JVC HD GR 1
Tape: Mini DV
Format: HDV
Software: FCP 5.1.4

Unfortunately when both "Capture" and "Device Control" presets are not set to HDV it wont even try to connect and gives me this warning:
"To capture HDV source material, both the Capture and Device Control presets must be configured for HDV; otherwise, to capture in another format, both must not be configured for HDV."
As a side note when my camera was connecting to FCP. FCP would only give me on screen controls half the time.

Unable to initialize capture device and device control in HDV

I shot with a Sony HVR-Z1U/Z1N and am using a Sony HDV 1080i tape deck to digitize.
I recently purchased a MacBook Pro and installed FCP Pro 5 on it. After getting over some time code issues we were chugging along, when on the 4th tape the image on the log and capture screen suddenly dissapeared (I could get audio and could see the image on the tape deck). Well after taking the tape out, checking and rechecking it I popped it back in and ever since then, I have been getting this error mssg "Unable to initialize capture device and device control."
I have tried deleting the preferences and starting from scratch. If I do that, and choose the easy setup with HDV- 1080i60, it gives me this error "Unable to locate the following external devices- HDV (1440 X 1080) 30fps.
I upgraded to FCP 5.1.2 this morning and upgraded the OS to 10.4.7 and QT to 7.1.3 and still no change.
Im at my wits end, Ive been working on this for a whole week now.
Thank you,

It has been reported to take more than one attempt to correct the installation but, if properly executed on a machine without other system problems, the QT reinstall process does work. The key element here is you must reinstall QT after you trash the receipts. The process is listed below.
x
To do a full quicktime reinstall.
Go to /library/receipts and delete any files that say Quicktime followed by a number e.g. Quicktime703.pkg
Go to the Apple quicktime site and download the appropriate version of Quicktime to your hard drive.
Run the Quicktime installer.
Repair Disk Permissions for your System Disk (Disk Utility > Select the system disk > Repair Disk Permissions)
Reboot
If this doesn't work, then the problem lies elsewhere:
1. your system - user preferences, firewire ports or other system elements.
2. your equipment - camera/deck/firewire cables.
3. your process - not setting up the software properly or using the software erroneously.
Listed below is a troubleshooting process. Not all steps are appropriate but the general process of isolating the problem is useful.

Unable to Initialize Capture Device - Works fine in iMovie

Am using a Sony HDV HDR HC1E Pal Handycam
Final Cut Pro 5.1
QT Pro 7.1.3
Works fine with cassettes in HDV - imports into FCP fine
Am trying to import a cassette recorded on that camera in DV LP
Works fine in iMovie
Have deleted the QT packages and reinstalled QT
Still am getting the 'Unable to Initialize Capture Device' message when using log and capture.
Settings on camera
VCR Auto (have also tried HDV or DV)
iLink conversion off (i.e.don't convert hdv-dv)
TV type 16:9 (have also tried 4:3)
Component 1080i/576i also tried 576i
Annoying thing is that works fine in iMovie but not FCP?!!
Any help GREATLY appreciated!
Thanks!

iMac 20 Flat Screen G5 1.8Ghz 1.5GB SDRAM Mac OS X (10.4.8) 200 GB and 120GB External Hard drives

I would like to add the following in hopes that someone will come up with a solution. The problem lies somewhere in Quicktime and the FireWire capture. I have the exact same camera and problem, and can assure you it has nothing to do with cam settings or DV LP. Once your system is stuck in this HDV mode, it would seem that regular DV can not be used again. I also have 2 other DV cams that are not HD. One is PAL, one is NTSC. I would further add that my external FireWire iSight no longer works in any application. I do not receive error messages, I simply get the spinning beach-ball of death.
I have a Dual G5 2.7 with 4 gigs RAM running FCP 5.0.4 on OS 10.4.8
I have run Cocktail, rebuilt permissions and re-installed Quicktime 7.1.3 four times as per Apples tech article 301852
I have used FCP Rescue 5 to clear preferences
I have captured footage from both regular DV cams to iMovie and then added the footage to FCP. The footage plays on the screen of both DV cams flawlessly via FCP. (I can also capture HDV in iMovie as well)
I have tried logging footage directly through the QuickTime application with both DV cams and my iSight and get the same beach-ball of death as FCP.
Why can iMovie work with these devices flawlessly yet QuickTime can not.
Why does it seem like the system is stuck in some kind of HD mode.
Just to point out the obvious:
I have no other FireWire devices other than the cameras and I only connect one at a time.
I have shut down, disconnected and re-connected before attempting to use the devices.
I have booted my G5 from a second system disk and everything (HDV cam PAL DV cam NTSC cam and iSight) function flawlessly on all the FireWire ports of my machine.
I have worked with FCP for about 6 years and Macs for 20. I understand the easy set ups etc.
Spent way too much time customizing my system to think about the clean install route, so I hope someone can shed some light on this.
Thanks

Wasapi: IAudioClient- Initialize() hanging when opening audio capture device

I'm trying to open the capture/input audio device. I call ActivateAudioInterfaceAsync() , then when I call IAudioClient->Initialize() on the capture device, the app hangs, supposedly because for some reason it's trying to display the 'Allow app to
use the mic?' prompt.
The hang _doesn't_ occur if I manually set the app permission to use the mic (i.e. launch the app without having it open the audio devices, open the permission tile, activate the mic permission).
Calls to ActivateAudioInterfaceAsync and IAudioClient->Initialize() are made from the UI thread (the one that receives callbacks for buttons, which on Metro style apps seems to be different from the thread that starts the application, i.e. WinMain).
What am I doing wrong?
I've attached the stack that shows the app hung below.
Thanks,
Flavio.

Video capture device bad image/no sound

Hi !!
I bought this "grabby" usb dongle from terratec to record old vhs cassete on my computer, but is doesn't work on linux. (It works ok on win7, so cable-connections problems are excluded)
On vlc I did 'open capture device', choose /dev/video0 for vid, hw:2,0 for sound(tried them all anyway), and PAL/SECAM video standard.
Problem is I have a super crappy video image (on mplayer also), and no sound. The video is colored, I recogize it, but the pixels are huge, it's awfull.
After some research I found that a module named em28xx is supposed to handle this device. I found some forum post here and there about the sound problem, it is addressed with a 3years old patch on em28xx-cards.c (which doesn't exist on my machine, so I couldn't apply it).
Here is dmesg :

From what I see my guess is that the module supposed to handle this hardware is present but doesn't do its job properly...any help?

Hi again !
Thanks for you tip nomorewindows. The programs tvtime and xawtv worked out of the box concerning video !! xawtv, however, crashes everytime I try to resize the (very) small window. As for tvtime, there is no sound (output is it can't open /dev/mixer so I guess it's fixable, I'll look into it).
I started reading the doc but I didn't found yet if it was possible to record the output with these program...
Concerning the cables, you are right they are not special at all it is standard : there is the triple (yellow=composite video, red/white for audio) cable and a fourth one for video but with inferior quality, I didn't connect it (it's either the yellow or this one for video)

How to change audio capture devices sample rate

I am going to develop a online voice chat applet. Now everything works fine. But I didn't find anyway to capture audio in a lower sample rate. The default sample rate is 441000Hz. I am using MediaLocator to capture audio and pass it into Processor.
MediaLocator ml = new MediaLocator("dsound://");
DataSource ds;
DataSource clone;
try {
ds = javax.media.Manager.createDataSource(locator);
} catch (Exception e) {
return "Couldn't create DataSource"+e.getMessage();

Use GSM format and do it with setting of BitRateControl. It is better than convert the sample rate of your capturing device. I suppose that you try to reduce load of network traffic with changing sample rate, right?
Best regards from Germany,

Capture device needed

I need a new capture device. I was using a Sony DCR-HC42 but it's no longer usable. Any suggestions?

Thanks for the reply Paul. I've been all through the manual for the HC52 and it never addresses the issue. I was at the store today and one of the sales people there actually hooked one up and tried it out. He couldn't make it work either. I think I found one that may the, HC62. I'll give this a try and it doesn't work I'll check out the ADS Tech. I remember seeing them at FRY's before, but I think it may discontinued.

Java: Capture Device in use...

Hello everyone!!!!
After an effort of two days (almost 20 hours), i couldn't find the solution and finally want any of you to, please solve my problem or guide me.
I have an application, when i run my application, it shows some GUI, i press Record, and it starts recording video through video cam.
Now when i stop it and again try to Record, it throws an exception, Capture Device in use.
I tried,
p.stop();
p.deallocate();before closing the recording screen but still there are issues. Can you kindly tell, how to release all the resources from the Processor(p is processor)
Thanks.

SOLVED...

Detecting Video Capture Devices without Installing JMF

Hi All,
I want to detect the video capture devices, without installing the JMF.
I had included the jmf (windows version) in lib path in netbeans ide. I am able to detect the audio capture device. But unable to detect the video capture devices. But if I install the JMF, I am able to detect the Video Capture devices in My system. Can anyone help me?
Thanks,
Vinoth Kumar.

YES! Please take a look at SIP Communicator project. They have all what u want.
The main idea is copy all .dll files to System or System32 (Please check files which JMF will copy to ur computer and where).
U need to have jmf.jar and sound.jar too ( maybe more) in your computer.
Your program should have DirectSoundAuto.java, JavaSoundAuto.java, JavaSoundDetector.java, JMFInit.java. Those files are in JMStudio source code. They are used to detect all capture devices and register it to JMF, but wait !!! where they will be saved? In order to save information about capture devices which are detected, you should create "jmf.properties" file in the same location with jmf.jar.Therefore, u should modify the JMFInit.java so it can check if the "jmf.properties" exists. If it's not, you have to create it.
Check SIP Communicator at Folder "media" then "device". They have modified those files I mentioned above and created some new files to SC can detect more devices.

Hello Wang,
> C *** ERROR => Couldn't initialize Oracle client library,
Have you also restored / re-installed the oracle client libs on your windows system? It seems like the oracle client libs are missing.
Regards
Stefan
