JMF video capture on OS X?

Hello,
is it possible to somehow do video capture under JMF? I use Mac OS X on Macbook Pro. I have found Quicktime for Java, but I would rather avoid using proprietary QuickTime APIs and work with portable JMF API. When I run JMF studio, I only see audio capture device.
Juraj.

You should take a look at the hardware requirements and supported formats for the cross platform version of JMF.

Be aware that JMF does not have its own video format, but supports proprietary formats like Quicktime.

JMF Video Capture in Vista

Hey all,
I have done a lot of searching on this matter, but most of the threads are old. I am wondering if there has been any updates or if this issue has been solved in any way.
I am trying to create an applet that captures an image from a webcam. I created the applet, using sample code found somewhere on these forums, and it works perfectly. I modified it to take 6 screenshots instead of 1 when the Capture button is pressed, and that works perfectly. However, when I developed this I was at work (Windows XP). When I got home and attempted to test my work further I got the following error:
java.lang.RuntimeException: No permission to capture from applets
java.lang.RuntimeException: No permission to capture from applets
javax.media.NoPlayerException: Error instantiating class: com.sun.media.protocol.vfw.DataSource : java.lang.RuntimeException: No permission to capture from applets

     at java.lang.Thread.run(Unknown Source)I read, through these forums and searching google, that IE is in a sandbox in Vista, which makes signed applets only able to access java related data and certain temporary directories, rather than the whole system like other OS's. However, we have other signed applets that create directories in Program Files folders, download files from the server, etc that work fine in Vista, so that makes no sense. Also, I have disabled Protected Mode on my my machine and turned all security measures off, to no affect. Also the same thing happens in Firefox.
Has anyone found a way around this for Vista? Does anyone know of another easy to use java API for doing this that works in both Vista and XP? Has anyone who has encountered this problem ended up developing something similar in another language (flash, etc)?
I require this applet for taking snapshots for a project for my job. I had preferred Java, because our other applets are all Java and I didn't want to mix techonologies too much. But if there is no way to do this in a stable way for both Vista and XP, then I will have to look at other languages.
Thanks for the help.

compbry, the fundamental problem is that Vista is 3 years old and the latest releast of JMF is like, 5 or 6 years old. So, there's nothing in the realm of "Vista compatibility" for JMF.
That said, to my knowledge no one has ever gotten JMF to capture video from inside an applet in Vista, JMF installed on the computer or not.
However, if you have JMF installed, you can easily run a JMF web-start app that will work just fine in Vista, that would allow you to do whatever it is you're needing to do.
But if you're going in a different direction, I'd suggest looking at the Adobe Flex API. It's free and from what I've researched about it, it makes webcam and microphone capture damn easy. If you've got a decent web server that will allow you to do ColdFusion or (can't remember the term for it, but you can write Java code that will run on-demand on the web host that your Flex application can talk to to do stuff like upload the images, etc...), it should be a relatively easy and short as far as LOC is concerned, minus of course the learning curve associated with learning something new (which is why I've only researched it, but I would've played with it too had I had a "decent webserver" ;-)

JMF Video Capture, output not properly

hello,
i'm trying to capture Video using JMStudio. my webcam is Logitech QuickCam IM, and it's detected succesfully by jmregistry. but then when i run jmstudio and start video capturing from logitech webcam, the output is only black and green, and beeping.
i don't know if anyone has ever experienced this before. what should i do to make it work?
Thank you.

Sorry, that last post was misposted. It was supposed to go on a thread where the OP did resolve his problem. Sorry about that!
If your web cam isn't V4L compliant and only supports V4L2, then it won't work with JMF. Also, if you're using the cross-platform pack instead of the Solaris performance pack, it won't work with JMF.
Finally, if you're running it as a user with insufficent permissions to access the hardware, it won't work (try running as root just to check this).

JMF Video Capture: Force capture format

Hi all!
is there an issue to force video capture format? I know I can set the string format but could you tell me how to make this string (new YUVFormat(new Dimension(176...)...
player = Manager.createRealizedPlayer(ml);
        player.start();
        FormatControl formatControl = (FormatControl)player.getControl ( "javax.media.control.FormatControl" );
        Format mform = new Format(/*Here the requested string*/);
        formatControl.setFormat(mform);Thanks ;)

In fact i succeed to set format, i just want to know how to make a right sentence (String) for the Format(String) constructor, including capture resolutio, fps ....

Jmf video capture

Hi iam new in jmf. The jmf alredy detected the capturing device , but not capturing video. only showing a black screen.while setting its parameters(RGB..) getting the error message "could not inetialize capturiing device". i am using windos xp.

Interesting read on JMF on wikipedia here
http://en.wikipedia.org/wiki/Java_Media_Framework
The article states:
Many JMF developers have complained that it supports few codecs and formats in modern use. Its all-Java version, for example, cannot play
MPEG-2, MPEG-4, Windows Media, RealMedia, most QuickTime movies, Flash content newer than Flash 2, and needs a plug-in to play the
ubiquitous MP3 format. [3] While the performance packs offer the ability to use the native platform's media library, they're only offered for Windows and
Solaris, the latter rarely used as a desktop OS. Furthermore, Windows-based JMF developers can unwittingly think JMF provides support for more
formats than it does, and be surprised when their application is unable to play those formats on other platforms.
Another knock against JMF is Sun's seeming abandonment of it. The API has not been touched since 1999, and the last news item on JMF's home
page was posted in November 2004.
While JMF is built for extensibility, there are few such third-party extensions.
Furthermore, editing functionality in JMF is effectively non-existent, which makes a wide range of potential applications impractical.

Q: Can I capture audio or video from within an Applet with JMF 2.1.1?
By default (for security reasons), JMF 2.1.1 does not allow capture from an applet. The user can turn this on by using JMFRegistry.
Run "java JMFRegistry", select the UserSettings tab and check "Allow Capture From Applets". If the browser's security permits loading native libraries, then you will now be able to capture audio/video from an applet.
but the program lines
try
player = Manager.createRealizedPlayer(ml);
FormatControl formatControl = (FormatControl)player.getControl("javax.media.control.FormatControl");
Component co = formatControl.getControlComponent();
Thread.sleep(2000);
player.start();
give always the same error

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.

JMF and video capture card?

i wanna ask how can i usea video capture card with the jmf and record video
i try to detect my capture card but the jmf didnt detecte it please pleas help me

hi,
i use a tv-card with my camera through linking them with a composite cable. Also, my tv card has capturing capability and i use JMF to do a capture program with these tools and the result is good for me. The monitor.zip file wihich contains a sample of capturing and monitoring simultaneously exists on sun.com. I use it and it was very helpfull for me.
JMF detects cards through its 'CaptureDeviceManager' which is a controller type object. If you specify like Vector devices = CaptureDeviceManager.getDeviceList(null) -> You will be get the list of appropriate devices on your pc.

Synched Audio and Video Capture in JMF?

I am in the planning stages of developing a speaker's corner for our university television station. Essentially, a button pressed by the user and a JSamp will send serial data to the computer(PC) that will execute the capture program. Before I proceed further, will I be able to capture both audio and video so that they will be in synch so that I can later bring both into a commercial video editing platform? Also, does the JMF support capture by firwire or USB only? Most of the forums seem to indicate that it is USB. Thanks, and any other advice would be appreciated.

Problem in video capture at server and fetching by client

hi
I am doing final year project it has server at one end which is connected to video capturing device-webcam in my case
and the client is mobile.
I want the live video captured be transmitted to the mobile client on fetch video request.
I have tried implementing it but facing some problems so would like to know the reason behing and also ask if the way i am following is correct or not
At server end i tried to extract frame as follows:
//the datasource handler class is as follows
      * Inner class MyDSHandler takes the Output DataSource form the
      * Processor and extracts the frame from it.
      * It implements the BufferTransferHandler so that it can receive
      * Buffer from the PushBufferStream.
     public class MyDSHandler implements BufferTransferHandler
          DataSource source;
          PullBufferStream pullStrms[] = null;
          PushBufferStream pushStrms[] = null;
          //Buffer readBuffer = null;
          int i = 1, j = 1;
          * Sets the media source this MediaHandler should use to obtain content.

               if(source instanceof PushBufferDataSource)
                    pushStrms = ((PushBufferDataSource) source).getStreams();
                    // Set the transfer handler to receive pushed data from the push DataSource.
                    //pushStrms[0] since we need to handle only the video stream
                    pushStrms[0].setTransferHandler(this);
               else if(source instanceof PullBufferDataSource)
                    System.out.println("PullBufferDataSource!");
                    // This handler only handles push buffer datasource.
                    throw new IncompatibleSourceException();
               this.source = source;
               readBuffer = new Buffer();
          * This will get called when there's data pushed from the PushBufferDataSource.
          * @param stream the PushBufferStream obtained from the DataSource

    }The problem i am facing is the client gets the black image just for a fraction of second and then the application hangs and no video is visible.
I have very little time left to complete this project as deadline is very close
please would be very grateful if guided timely.

because i want live video to be seen at client end i am seriously confused and the progress as just come to an hault at this point and am in real need of guidance.You should probably be using RTP and the tradional way of using JMF then...

Read through all of the links I gave the person on the above thread and you'll be on a lot better footing as far as using JMF goes.
shall i send the server side code.Till now server and client are both on local host.No, I don't need to see any more of your code. I'm not a proof reader, and I'm not going to debug it for you. Do you own work.

Video capture and than transmit it

After I made live video capture from (and play it with Man Media Player) I want to transmit this stram (using RTP) to other computer. How could I do this? Thank you.

I used VideoTransmit.java sample from Sun (JMF solutions...). My problem is: I want see what I transmit. For this I need a Player for my Data Source. If I used a player for my Data Source I cann't used it for transmit. It is already allocated. I could clone my data source and use one for player and the other one for transmit. It works thus. I tried it. But the stream locks from time to time. I need other solution. If I used JMStudio->File->Transmit... the stream is played and transmited very good.

Error Msg Prompted when exit a Video Capture applet

I converted a sample Video Capture App to a applet, when i stoped capturing and exit, this massage prompted:
"The instruction at '0X05a82f30' referernced memory at '0x05aa20f8', The memory could not be 'read'. Click on OK to ternimate the program".
This app will write the captured video file onto local disk, but i've setted the security options in JMF Preference config.
I just wonder why this error message occur?
i'm now working on this applet for my JSP page, i want users can captrue pictures from the WebCam and then save as JPEG images.
I realy appreciate it if any guys can give me some suggestion?

I also writing a applet to do that. But I can work in application model. When I run it in browser . It throw out an error. Following is my code....

1..This is the code which we used for capturing and saving video in the disk..But we got a mov file created zero size..what is the reason for that..Can any one suggest a better way for this..
2..Is Creative Webcam II supported by JMF 2.1 ..
3..Suggest any other format for audio and video capturing and saving..
Thanks in advance..

Thanks T.B.M..
It worked..My webcam details are as follows:
{color:#ff6600}Name = vfw:Microsoft WDM Image Capture (Win32):0
Locator = vfw://0
{color}
It suports the following formats..
{color:#ff6600}
0. javax.media.format.RGBFormat
RGB, 320x240, Length=230400, 24-bit, Masks=3:2:1, PixelStride=3, LineStride=960, Flipped
1. javax.media.format.RGBFormat
RGB, 160x120, Length=57600, 24-bit, Masks=3:2:1, PixelStride=3, LineStride=480, Flipped
2. javax.media.format.RGBFormat
RGB, 176x144, Length=76032, 24-bit, Masks=3:2:1, PixelStride=3, LineStride=528, Flipped
3. javax.media.format.RGBFormat
RGB, 352x288, Length=304128, 24-bit, Masks=3:2:1, PixelStride=3, LineStride=1056, Flipped
4. javax.media.format.RGBFormat
RGB, 640x480, Length=921600, 24-bit, Masks=3:2:1, PixelStride=3, LineStride=1920, Flipped
{color}
So made the following changes in my code..
dl=CaptureDeviceManager.getDeviceList(new VideoFormat(VideoFormat.{color:#ff6600}RGB{color}));
ml=((CaptureDeviceInfo)dl.firstElement()).getLocator();
formats=new VideoFormat(VideoFormat.RGB);
model = new ProcessorModel(ml,new Format[]{formats}, new FileTypeDescriptor(FileTypeDescriptor.{color:#ff6600}MSVIDEO{color}));
p=Manager.createRealizedProcessor(model);
source=p.getDataOutput();
sink = Manager.createDataSink(source, new MediaLocator("file:///c:/Adiyae.{color:#ff6600}avi{color}"));
p.addControllerListener(this);
p.realize();
Now the file is getting created with its size depending upon how long i capture..This is fine..But when i try to play the file using a media player it doesnt open.. when i tried opening it with JMStudio i get the following message..
{color:#ff6600}Controller Error:
Failed to realize:Failed to parse the input media..
{color}Also can you tell me how to choose the FileTypeDescriptors for a particular video format.. The only FileTypeDescriptor that works with mine is the MSVIDEO..
Thanks in advance..
