I have new in JMF-Any one help me
Hai
I am beginner of JMF.i have facing one problem for past 3 days.
I wrote one applet program for playing mp3 song.Atfer i wrote one jsp file it has several radio button when i clicked any one of them it would called applet(i have using plugin tag for this embbed).i got one error i.e. Class not found exception.but i tried in appletviewer it's work perfectly.
My path folders are:
Applet program: c:/Tomcat/webapps/Vj/web-inf/classes/AB.java
Jsp File:c:/Tomcat/webapps/Vj/playapp.jsp
My code is applet code
import java.applet.Applet;

</APPLET>
public class AB extends Applet
implements ControllerListener
public SimplePlayerApplet()
player = null;
public void init()
MediaLocator medialocator = null;
Object obj = null;
if ((s = getParameter("FILE")) == null)
System.out.println("S value is:NULL");

System.out.println(noplayerexception);
Fatal("Could not create player for " + medialocator);
catch(MalformedURLException malformedurlexception1)

public void start()
if(player != null)
player.start();
System.out.println("This from start");
public void stop()
if(player != null)
System.out.println("This from stop");
player.stop();
player.deallocate();
public void destroy()
player.close();
System.out.println("This from Destory");
void Fatal(String s)
System.err.println("FATAL ERROR: " + s);
throw new Error(s);
Player player;
}now i run in appletviewer it's work perfectly.After that
I remove applet tags in this program and again i was compiled.
then now i embeded in jsp .

K.sureshIt might be if you explain "the Problem" - whats the error
for a start? -
I have pretty much the same questions about using JMF Player. I'd prefer to get people using JMF because I have more control over how my video is presented in the web page. Sorry this isn't an answer to your question but did you come to any conclusions about usefulness of JMF Player?
matt bentoni am a beginner to jmf .
first i would like someone to show me how to display three frames at a time using JMF.
i have simple code.
when i click forward button it will go to next frame.it is working fine.
but i want to disply at a time three frames when i click next button again it will show next three frames.
i am sending working with one frame code.
please send me code to [email protected]

Cannot stop a player when is playing
hi,
i'm a beginner in jmf and i'm traying to do a simple player application: i have 2 buttons, a start button and a stop button.
the start button starts the player:
player.realize();
player.prefetch();
player.start()
and the stop button try to stops the player:
player.stop();
player.deallocate();
player.close();
if i realized the start button and inmediatily the stop button de player stops, but when the player is started the stop button don't works. any suggestion ?
thanxthe start button starts the player:
player.realize();
player.prefetch();
player.start()
and the stop button try to stops the player:
player.stop();
player.deallocate();
player.close();I think you're putting too much into your buttons -- particularly the stop button, since closing means you can't restart the player.
It would be better if your buttons only did start() and stop(). You can realize your player in the process of building your GUI, and you can put the close in a shutdown method (eg, something you call when the window is closed).
I think deallocate() is unneccessary if you're just going to close()

Simultaneous stream playback and export to file
I'm trying to write a client application that receives an audio stream via RTP. I can get it to playback the stream using a Player as the audio is being received and I can also get it to export the stream to a local file using a Processor as it is being received. However, I cannot seem to merge the two functionalities. I think the problem is with using a Player and a Processor connected to the same DataSource. The error is that the Player is never initialized. The controllerUpdate method is below and it seems that it never reaches the player.realize call. I am a beginner at JMF so maybe I haven't learned enough about MediaEvents. Any help would be appreciated.
public synchronized void controllerUpdate(ControllerEvent control)
Controller myController = control.getSourceController();
if(myController instanceof Processor)
if (control instanceof ConfigureCompleteEvent
|| control instanceof RealizeCompleteEvent
|| control instanceof PrefetchCompleteEvent)
synchronized (waitSync)
stateTransitionOK = true;
waitSync.notifyAll();
} else if (control instanceof ResourceUnavailableEvent)
synchronized (waitSync)
stateTransitionOK = false;
waitSync.notifyAll();
} else if (control instanceof MediaTimeSetEvent)
System.err.println("- mediaTime set: "
+ ((MediaTimeSetEvent) control).getMediaTime().getSeconds());
} else if (control instanceof StopAtTimeEvent)
System.err.println("- stop at time: "
+ ((StopAtTimeEvent) control).getMediaTime().getSeconds());
control.getSourceController().close();
if(myController instanceof Player)
Player player = null;
// If player wasn't created successfully from controller, return
player = (Player) myController;
if (player == null)
System.out.println("Player is null");
return;
if (control instanceof RealizeCompleteEvent)
System.out.println("HELLO");
PlayerWindow pWindow = find(player);
if (pWindow != null)
pWindow.create();
pWindow.setVisible(true);
player.start();
if (control instanceof ControllerErrorEvent)
player.removeControllerListener(this);
PlayerWindow pWindow = find(player);
if (pWindow != null)
playerWindows.removeElement(pWindow);
System.out.println("Error in ControllerErrorEvent: " + control);
}Okay, then here's one possible method to do something like this:
$totalSize = 0
Import-Csv .\fileListing.csv | ForEach {
$fileDetails = Get-Item $_.FilePath
$props = @{
File = $fileDetails.FullName
'Size(B)' = $fileDetails.Length
$totalSize = $totalSize + $fileDetails.Length
New-Object PsObject -Property $props
} | Select File,'Size(B)' | Sort File | Export-Csv .\fileReport.csv -NoTypeInformation
(Get-Content .\fileReport.csv) + "`nTotal Size,$totalSize" | Set-Content .\fileReport.csv
This assumes an input CSV named fileListing.csv with a header of FilePath for the paths.

Video Capturing and Transmission
I would like to create video streaming application, that i want to capture a video by using the webcam and then store in a buffer area that created, then the video is streaming out through network from the buffer.My problem is how do i create a buffer and save in it after capturing the video using JMF?I am a beginner to JMF. I appreciate any
examples and advice.
Many thanks in advance.
littebinHi,
You can use RTP Transmission for Transmission which will transmit your live Video. In the same system you can RTP Receiver through which you can store the Live Video.
Thanks

How to capture and save voice from microphone

Live Audio / Video Streaming Very Basic
I need to Stream Live Audio and Video, i went through a web site, and it gives a code,
[http://www.cs.odu.edu/~cs778/spring04/lectures/jmfsolutions/examplesindex.html#transmitboth]
in this, i dont no how to run the application, because we should have 2 port addresses each for Audio and Video.
how do u compile this and capture the file from else where using JMStudio.
Please help me, i am an absolute beginner to JMF.Please don't take this to be offensive, but if you're not able to figure this out on your own, you have absolutely no business playing around with something as advanced as JMF. It's not a question of intelligence or insult, but simply stated, if you don't understand the concept of a URL, and you don't have the ability to extrapolate beyond the exact command-line input you've been given... you need to go and learn the basics, because you lack the grasp of the fundamentals required for advanced programming.
With that in mind, the following is the answer to your question. If you can't understand it, it means that you lack the fundamentals necessary for JMF programmming, and you need to invest a significant amont of time aquiring those. My explanation should be quite clear to anyone with the proper Java programming fundamentals.
AVTransmit2 is sample code that can broadcast a single media source (live audio or live video or audio file or video file or video/audio file). It does not have the capability to broadcast more than once source, which is required for live audio and video support. It is designed to take in a single media locator, and broastcast it.
To meet your specifications, you will need to modify the main method so it is capable of passing in multiple media locators, and thus creating multiple instances of the AVTransmit2 class. To do this, you will either need to modify the command-line argument logic so it supports parsing multiple source arguments simultaniously.
Or, you could just rip out the command-line stuff and hard-code it for live audio and video. That's the "easy" way.
The default media locator for audio capture is javasound://0 and the default media locator for video capture (under Windows) is vfw://0 -
Please help me by explaining what happens with the Codec.process() implementation of this URL:
http://java.sun.com/products/java-media/jmf/2.1.1/solutions/FrameAccess.html
This custom codec is supposed to access individual decoded video frames from a Processor while processing the media. This could be used for scanning the decoded data;computing statistics for each video frame, and others. I'm a beginner with JMF, so please explain this code:
public int process(Buffer in, Buffer out){
Object data = in.getData();
in.setData(out.getData());
out.setData(data);
//Why swap the data?
out.setFormat(in.getFormat());
out.setLength(in.getLength());
out.setOffset(in.getOffset());
//Why copy the input attributes to the output?
}Basically, I found out what was going on with some experimentation...
in the beginning if you do a getData() on the Output Buffer you will see it is null for a while (5-6 on my machine)... then you start to get data... these are for recylcing byte arrays... so if you send a byte array (e.g. ) in the output buffer and then watch for it... it eventually comes back to you... and similarly for all the byte arrays one creates...
This allows two things to happen:
1. recycling of byte arrays
2. you can send data from a later codec to an earlier codec all one needs to do is set the data on the Input Buffer of the nth stage and you will get it in the Output buffer in the (n-1)th stage....

Beginner Question. need opinion on using JMF
i am hoping to use JMF to have a audio/video chat session . it will be like there will be 5 PC's . and 1 PC will be streaming a video, the other 4 PC's will be showing it.
what i want to do is to draw lines or make some mark on the video thats been telecast (from the other 4 PC's), and that change to be shown on all 5 PC's
is this do-able ? and i hope my question was not confusing .localpott wrote:
is this do-able ?Yes. JMF has the built-in capability to broadcast a stream to multiple participants simultaniously, and it works a lot like email. You just add a few more recipients to the list before you press send.
As for drawing on the video, that'd be relatively easy to do. You'd just need to develop a layering system, whereby a "bottom" layer renders the video frames, and the upper layer renders / modifies the drawing. You'd just then need to create a video "Effect" class that would grab the upper layer, render it on top of the current video frame, and then it would come out of the Processor with the drawing on it. -
can u please have a look to the attached file
i know that this involves the jmf API but I have the feeling that has to do more with swing, thats whay I post my question here
this simple application is based on the MDI.java example of the jmf web
pages
I also added a slider and want to set the playback rate for the player from
there if possible
that is I want everytime that I move the slider and the value is biggerthan
50 the rate to be reduced according to a simple calculation that converts
the slider value to a value between 0 an1 for the rate...
so all i want to do is pass the slider value to the player everytime that
the slider changes value and this is bigger than 50
the attached file can do that only when the player starts playing the
file,,,,
after the player has started and the rate is set I cant change it even if
the slider moves
when I tried to do that from within the stateChanged method of the slider I
was getting a Nullpointer exception because of the EventDispatching thread,
so I thought to take this piece of code out of there (create the setnewrate
method in the jmframe instead),,,,but then of course doesnt work like I
would want,,,,,
do I have to register the class that implements the frame for the player as
a ChangeListener on the slider to achieve that, is something like that
possible....
I know that swing is not supposed to be thread safe, so maybe this is what
the problem is after all...any suggestions to that direction?
Can u please have a look??
I am a beginner so any help would really be very much appreciated
thanx :)
maria
.....and the attached file
I think the problem is with the stateChanged method for the Jslider...
I am getting a null pointerexception because of the eventdispatching thread

i am stuck so any help would be really very much appreciateddid you ever resolve this.
I may be having similar problems
I have an JMF application running under webstart. It runs ok in Java 1.3
Now I am trying to get ti to run under Java 1.4. The attached error is rather useless,
but by guess at what is happening is that the JMF control has some .awt. stuff included
but that Java 1.4 emulates .awt. in swing. But something was not set and the default does not
work.
This error messages does not appear in the 1.3 run
Any suggestions would be greatly appriatated.

JMF why player cannot be realised?
Hi everyone,
I am a beginner in java programming and right now doing a project on socket programming. We are supposed to play various media files types with embedded player. Here i use some JMF funtions such as javax.media.player into my code. Actually if I installed the jmf-2_1_1e-windows-i586.exe into my computer, i can run my code and play vaious media files. However we should not ask all the clients to install JMF before they can run our code. Therefore i tried on the other computer without installing the jmf exe file, but just to add new library with the customizer.jar, jmf.jar, mediaplayer.jar and multiplayer.jar. My code has no error detected however i cannot play any music files on my second computer. It always has error in the output window saying " player cannot be realised". Even if i tried exactly the same media files on both computer, the one with installed JMF .exe can play those files, and the other without cannot play.
Anyone knows how to solve the problem? Besides creating new libraries containing those jar files from jmf folder, what shall i do to make the code working yet without installing the jmf exe file into my windows?
Thanks in advance for your help!
Edited by: ll1728 on Mar 9, 2009 2:46 AMHi, T.B.M, really thanks for your timely response.
I have downloaded the cross platform version of JMF, and have added the jar files into my project library. Well, this time round is I can play the sound of the mpg file but without image. As i read from <http://forums.sun.com/thread.jspa?threadID=570424&tstart=28> this link saying that "MP3 is supported only on the Windows platform", i tried to put some plug-ins like fobs4jmf. However it still didn't solve my problem.
When i added in the fobs4jmp.jar into my library, i can play avi, mpg file with only image but no sound.
When i remove the fobs4jmp.jar, use only cross platform jmf jar files, the only file format i can play is .mpg. But there is only sound no image displayed.
Do you have any idea what i should do? I have searched online myself but didn't find any clue.
Thank you so much for your help. -
Well I'm a beginner!
I have a lot of problems with JMF, I installed it but i cannot use the javax.media package.
Documentation says I have to give the class path variables and etc etc........
I did not get anything. Can any 1 help me out with the path variables.
I run Windows XP.
Java is installed at C:\Program Files\Java
JMF is installed at C:\Program Files\Jmf2.1e
I would really appreciate your help.
Please help me with any info on JMF.
[email protected]Under WinXP you should be able to right click on "My Computer", select Properties and then click on Advanced (I think), then you should see an option called Environment Variables .... in here you can add/edit your CLASSPATH.

I was looking at JavaSound; I assume I'd have to rewrite everything to use that? Which I would hate to do. I've been off this project for awhile (and Linux and JMF) and it's hard to remember it all. Certainly is a fallback though, thanks.No, you don't have to rewrite anything because the code I gave you is a DataSource for JMF that will capture audio using JavaSound's technology and deliver it to JMF, so whatever JMF infastructure you've already built would be unaffected...
