Why there's no Vidio Capture Device?

I just begin to study JMF and want to capture the vidio, using following codes:
Vector deviceList = CaptureDeviceManager.getDeviceList(new VideoFormat(null));
if (deviceList.size() > 0) {
cdiVideo = (CaptureDeviceInfo) deviceList.firstElement();
} else {
System.out.println("No Vidio Capture Device get!");
System.exit(-1);
But it always said "No Vidio Capture Device get!". I don't know why. I have replace the "null" in "VideoFormat(null)); " with "CINEPAK", "JPEG" and all other formats in Class VideoFormat's Field, but it still didn't work. However, I do have a Video Camera . Why here it said "No Vidio Capture Device get!"? Can anyone help me?

I resolved it myself.Just resetup the driver.

Are there any video capture devices available on Linux?

Are there any video capture devices available on Linux?

If you have a tv tuner card with either an s-video or av/ composite connection, then you can use that under linux with a digital video camera (dv camera). I can help if you are interested. Hope this helps!

Why has Premier stopped recognizing my capture device?

I'm capturing HDV from a JVC BR-HD50. Premier was recognizing the device but now all I get when I open the capture window is the message "Capture Device Offline". I don't know what has changed that should affect this.
The computer is recognizing the BR-HD50 as a 61883 Class Bus Device. It is connected through a firewire port.
I can capture with it using Premier Pro 2.0 on another work station, so I know the BR-HD50 is working fine.
Should I maybe uninstall and reinstall Premier, with the device plugged in?

No, I haven't, because I'm not sure when the problem occurred and there have
been quite a few restore points since then. Still, I may try that. Thanks.

How to connect a video capture device to Satellite M30X 127

I'm going around in circles trying to find a video capture device that will function with a laptop and would be grateful for advice. By way of example, I'm now looking at the 'Canopus ADVC-110', although still looking around (but not Pinnacle, who seem to have a terrible reputation for capture items).
Problems include:
1. Main problem is - many video capture external devices require a 'line-in' to PC for good quality audio transfer. This laptop doesn't have a line in, only the mike and headphone jacks. In addition, I've also tried a few RCA pins in the 3.5mm microphone/headphones jack and they were too small. How to solve the problem of getting audio from vcr to my PC?
2. The ADVC-110 connects to the PC via Firewire (and S-video), but is a SIX-pin type. M30X is a FOUR-pin type. Are there adapters available?
3. Some capture programmes seem to require huge capacity of RAM. Is a laptop going to be suitable to do the job? (I simply want to capture old vhs tapes from vcr to PC, then burn to DVD with Nero 7 or similar).
Thanks in advance!

Hello
You are right! You must use external device for signal transfer to your notebook. I dont know where you have this info but I have good experiences with Pinnacle product. For data transfer I have used USB port.
'Canopus ADVC-110 is not known to me but I dont see any reason why this should not work well. Use delivered software for video capturing and there should not be any problem.
Only thing is that after recording the whole video material must be prepared for burning and unit need a lot of power to do this well und fast. When you buy this and want to use on right way I recommend you to expand RAM to 1GB.
Compatible memory modules for your Satellite M30x are:
PC2700 512MB (PA3312U-1M51)
PC2700 1024MB (PA3313U-1M1G)

Use a capture device twice at the same time?

I have write a application using JMF. But I have a big question that how can I use a capture device several times at the same time????
For example:
I create a player to play video from my webcam on my PC ,and then I want to send the video stream from my webcam to another PC at the same time. But I failed--only one task can work.
For example:
1, I write a class Player and another class RTPTransmit. Then I send the same medialocator to two of them. Then there will be a exception said that capture device is in use. And only one task can work.
2, I write a class Player and another class RTPTransmit. Then I use :
dataSource1 = Manager.createDataSource( locator );
dataSource2 = Manager.createCloneableDataSource( dataSource1 );
then I send dataSource1 to Player object to play video on local PC and send dataSource2 to RTPTransmit to send video to another PC. But only one task will work too.
My question is that how can I use a capture device several times at the same time???
I have tried several ways and sill can not find a method. If anyone know how to do,could you tell me please? Thank you very much.

Yes ,I use Manager.createCloneableDataSource() method to create the clone of the datasource ,but it can not work too. The java doc illustration is :
Creates a cloneable DataSource. The returned DataSource implements the SourceCloneable interface and enables the creation of clones by the createClone method.
If the input DataSource implements SourceCloneable, it will be returned right away as the result. Otherwise, a "proxy" DataSource is created. It implements the SourceCloneable interface and can be used to generate other clones.
When createCloneableDataSource is called on a DataSource, the returned DataSource should be used in place of the original DataSource. Any attempt to use the original DataSource may generate unpredictable results.
It means that if I clone a datasoure from original datasource, then the createCloneableDataSource() method will return a datasuouce implements interface SourceCloneable, right ? I see that the intereface SourceCloneable has a abstract method createClone() , but when I use createCloneableDataSource() to get a source clone, I find that I can not use method createClone(), why??? For example: data1 is the
orginal datasource. Then:
DataSource data1 = Manager.createDateSource( locator );
DataSource data2 = Manager.createCloneableDataSource( data1 );
now data2 is the "proxy" datasource which implemnets the interface, right? But I can not use data2.cloneClone() ,why? Then I write the fllowing code:
DataSource data3 = Mangaer.createCloneableDataSource( data2 );
DataSource data4 = Manager.createCloneableDataSource( data2 );
playOnLocalPc = new PlayOnLocalPc( data3 );
playOnLocalPc.start();
rtpTransmit = new RTPTransmit( data4 );
rtpTransmit.start();
PlayOnLocalPc and RTPTransmit is my own class to play or transmit video stream. But they can not work at the same time. If I play video from webcam on local PC and then start to transmit stream to other PC , the play window will become black. Why?????It is too strange. Dose anyone know the reason ,please tell me, thank you very much. Giving some example code will be better:) Thank you again!

Importing problems (hi 8 camera-capture device-imovie)

i am importing from an old canon es3000 hi-8 (analog) camera, through a miglia "director's cut" capture device, to imovie (via firewire) ... there is fragmented line at the bottom of the frame in imovie during import. will that show up in idvd later? also, the imovie is not seperating the clips, so i end up with one long clip. after about 10 minutes the digital footage in imovie becomes fragmented throughout the frame. does anybody know why this is happening? thanks in advance, R.B.

Playing video from a capture device - Out of memory for video buffers?

Hello guys, I'm having problems playing video from a video capture device when not using JMStudio. When I use JMStudio, the video plays real time with no problems, but when I use code taken from a java book which is a simple Media Player, I get the following error:
"Error is Error: Out of memory for video buffers."
My capture device is working and I don't know why i get this error when trying to watch the video feed from a program other than JMStudio. I also tried different code that has worked in the past with the same exact capture device and I still get the same error. Please help, I have no clue at this point. The code for the simple media player is below, it's taken out of the book "Java: How to Program (4th edition)":
Thanks in advance, I am very greatful
Miguel

When I type the locator, I am typing vfw://0, I also tried just vfw://
and I get the same error.

Looking for RCA capture device for streaming

My newspaper does some random video streaming of some events...however, we generally use a Windows PC Laptop (which is less powerful than the MacBook Pro I'm wanting to use, for several reasons such as convinience and well, the better performance).
We have a RCA capture device that takes video and audio in from a basic Canon video camera and then feed that into Livestream.
I know Blackmagic Design has a video capture device for Apple, but it's $149. Is there something cheaper out there for Macs? Our RCA capture device we use on Windows will not work on Mac.
It just takes the RCAs and we plug it into the USB port. A firewire port would be fine too.

I have read through some more forums and I only found one mention of the Media Manager 'Recomress' function.
It said:
"Transcoding with MM (recompress). It preserves timecode/reel name, file names, etc... Except the clip ID, which is used along with reel name and timecode to batch capture from source files (at least for P2)."
Clip ID is the metadata relyable for the work of batch capture. It seems without it it is impossible to batch capture.
I wonder why they designed Recompress like that, if it is true?

HDMI capture devices for IMac

I noticed that blackmagic design are moving on to less expensive USB 3.0 in their HD video capture devices so I did a bit of lookin around to see weather the Imac or mac book pro could somehow be outfitted with usb 3.0 connections. It turns out that the mac book pro will work with a usb 3.0 card. Unfortunately though, black magic still does not doesn't show any signs of addressing support issues for apple and the usb 3.0 device compatibility issue. Does anyone know which way apple is leaning on the whole usb 3.0 thing. I'm pretty sure it offers exceptional increases in speed over even fw800. Or at least the potential for those increases as a matter of spec. And why not jump on the blueray-r while were at it.

No, there is not. HDMI options on capture cards didn't arrive until after MacPros were released and G5s were discontinued. The only capture cards that work on G5's do not offer HDMI inputs. The Intensity series are PCIe only...AJA Kona line with HDMI are PCIe only....Matrox MXO2 line are PCIe and Express34 only. And your G5 has PCI-X slots.
The AJA Kona 2, Kona LH, Decklink HD cards...things you can only find second hand...do not offer HDMI inputs. You are on a machine that was discontinued 4 years ago, HDMI support was not invented yet.

Analog Capture Devices

Hi
I have this USB Analog / DV capture device called "USB instant VCD".
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=41536 7&Tab=0&NoMapp=0
I was using it on a pc. Plugged it into the Mac and tried to install drivers from the disk but kept getting "error opening movie"
but it was an exe file not a movie.
Im trying to hook up the VCR to the mac to burn sometapes to disk.
why wont it recognise the device? I thought an exe file should self open when you click it?
am I missing something?
best, M/

USB transfers data in packets, in bursts of information. For video work, you want the constant stream of Firewire.
FCP will not work with USB cameras or capture devices. It will work with USB hard drives, but it is not recommended.
Take up the other matter with ADS. Perhaps there is a Mac version of their software on their website. Either way, it's not going to interface directly with FCP, but maybe you can get the files on your drive and then import into FCP.

Capturing device offline

I keep getting "Capturing Device Offline". Other than making sure all wires are plugged in correctly and and the camera is on VCR is there any other way to trouble shoot this problem?? I already went out and bought a new firewire plug and IT doesn't work either. Keep getting the same messsage.

Sorry, Bill, I did check those settings out and found them to be DV, but failed to mention that in my last post. Still alittle frustrated, tho, on why everything seems to be connected and the settings are correct but still get that message. I even bought a new firewire thinking it might be that, but no change. Any more suggestions?

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,
Bugs

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.

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.

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)

Why there's no Vidio Capture Device?
