Troubles with Tribbles! ... er I mean Trouble with JMF

Recently downloaded JMF and updated my classpath for both
JMFHOME=C:\JMF2.1.1
CLASSPATH=%JMFHOME%\lib\jmf.jar;.;%CLASSPATH%But, my Eclipse IDE does not want to recognise the javax.media library... any ideas?

Huh... didn't know that. Is that because it doesn't require the JDK to run apps through Eclipse? Why does Eclipse ignore the system classpath?When Eclipse is launched, it defines its own classpath, which does not include a user's system classpath. Equivalent behavior is seen with the use of the -classpath flag with java and javac, where defining a classpath at startup disables the automatic inclusion of the system classpath. This helps reduce library conflicts.
How might I go about doing so? This is a new concept for me.[Eclipse docs - Java Build Path Page|http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse.jdt.doc.user/reference/ref-123.htm]

FSM with JMF 2.1.1(a) and one more problem. !! URGENT

Good AfterNoon All...
I am working on JMF 2.1.1 and I want to show a .avi file in fullScreenMode.
How can i do so with jdk 1.4.
I have gotten viewComponent and control comp.
My application is running sucessfully. NO PROBLEM.
But i want to show the movie in FSM . In order to do so, what i am doing is , I remove view
Comp from my JFrame (in which whole of the process is going on.) .
Add that viewComp in fullScreenWindow (which is initilized Window with parent frame.).
But here some problem is there. According to me, it is painting problem.
viewComp is removed successfully from frame but not added in window.
Layout of window is border and i am adding viewComp in center of window.
Running movie is not visible in Window. WHY ? what could be the possible reason.
Is it possible or It can't happen. ?
One thing more.... HUH...
I have a menubar in frame with file and tool menus.
when player initilized and movie starts running . You know what happens.
Clicking on menu(s) doesnot cause menuitem(s) to visible or pull down. ?? Oh ! GOD.
viewComp is at center and controlComp is at South.
When i click on say fileMenu. file Menu pressed as always happens with swing's color but menuitems donot visible.
WHY ?
It seems that menuitems are visible ....hamam.ma...mmm I mean they are hided by viewComp.
how to get ride of this problem. ?
Any idea is highly appreciated.
And it is nice working with JMF.

Nobody .... ??
I have found the answer of my 2nd question but still first is creating problem.
Does anyone know it.. how to do it..
Full Screen Mode in JFM.
Thanks

Detection problem on HP webcam with JMF

Hi,
I'm trying NyARtoolkit and I need to use the video stream of my HP's webcam encrusted above the screen of my laptop (a HP Pavillon tx 2670ef)
After the installation of JMF, I lunch JMStudio and I manage tu detect my webcam in : File->Preferences->Capture Devices->detect capture devices.
Then i close the windows and i do File->Capture...->I enable "use video device" and unable "use audio device" then i click on "OK" but aftewards i have an error message saying that JMF couldn't initialize the capture device...
2 students with me have the same pb...
I made some researches about this issue and i found this post
http://72.5.124.102/thread.jspa?messageID=10177842
Afterwards I've installed ManyCam and i managed to get a video capture from the virtual webcam simulated with ManyCam.
In fact, when i click on detect capture devices in JMStudio, a windows appears and i can choose "ManyCam Virtual Webcam" instead of "HP webcam".
Moreover, in the options before capturing video, the encoding is in RVB instead of YUV before with the "HP webcam".
But when i run my program i have this error :
java.lang.ArrayIndexOutOfBoundsException: 0 >= 0

Coud you help to use my webcam with jmf ?
josy

You probably want to remove the crust from your web cam if you expect it to work. Most things that are encrusted aren't in the best of shape...
JMF connects to web cameras by wrapping around native interfaces. If the JMStudio isn't able to use your web cam, it could mean a number of things...your web cam isn't compliant with the version of the interfaces (VFW and DirectShow, I believe) that JMF is wrapping around, the web cam doesn't output any formats JMF can use, etc.
But if JMStudio can't use your web cam sucessfully, 99% of the time that means your web cam isn't going to work with JMF... unless you want to code support for it yourself.

How to use JFFmpeg with JMF

Hi ,
I am trying to use Jffmpeg with JMF to extend the supported format in JMF. I added jffmpeg-1.1.0.jar in class path variable.And I also made necessary changes to JMF Registry for JFFMPEG given in following url:
http://jffmpeg.sourceforge.net/download.html
But I could not play any mp4 video with JMF Studio.
So,can any one help me to solve this problem?
Thanks in advance

Jyotirmoy

This may not help much re Solaris, but is worth putting up here for reference for others, whilst the code structure may also be useful anyway being close to pure java and as a solution that reads & saves every frame.
For Windows the folder in the zip includes Fobs4jmf, and - if necessary - setting preferences via the runjmstudio.bat should mean that the sun.bat will work for .mp4 and .flv video files.
See vid2jpg.zip at http://www.exactfutures.com/index02.htm which includes the java source.

Problems initializing webcam device with JMF

Hello,
JMStudio works fine on first try. Webcam stream is captured and displayed.
If I start JMStudio a second time, an error occurs "Couldn't initialize Webcam Device".
After rebooting my laptop it works again once.
Same errors occur with all example scripts using webcam device.
I'm using Windows Vista Home Premium 32Bit and a Vega USB 2.0 Camera (integrated in my laptop)
Thank you in advance.

Why wouldn't it work correctly the first time if JMF isn't releasing it correctly?
It seems the webcam connection isn't executed correctly on exit, so it can't connect again the second time.Connection isn't executed correctly on exit? You mean JMF isn't releasing your web cam, correctly, when it's done with it... I feel like someone just said that...
I just installed JMF today and JMRegistry recognizes my webcam and And the fact you only installed it today rules out the possibility than something went wrong during installation...why?
unfortunately I couldn't find drivers for the webcamWhen I suggested that you make sure you're using the correct drivers for the web cam, just to be clear, I was referencing the drivers for your operating system, not anything to do with JMF.
If you're using the incorrect drivers in the OS, whenever JMF sends out a "release the web cam" command, incorrect OS drivers may not be able to release it correctly.
All sarcasm aside...you should try reinstalling JMF, to make sure nothing funky happened during the installation...and you should make sure that Windows is using the latest, best, most accurate drivers for your web cam, to make sure that you're not using a flat-head screwdriver to try to screw in a Phillips head screw...

How to use ffmpeg with jmf

I am trying to use ffmpeg with jmf. Do any one have any idea how to do it.

Trouble installing jmf

I having trouble installing jmf on my laptop runing Windows XP. I downloaded the jmf-2_1_1e-windows-i586.exe onto my computer and it run succesfully, but I am still not able to import javax.media into my jdk. When I run JMF diagnostics it also tells me that JFM classes - Not Found.
Can someone please help?

jmf-2_1_1e-windows-i586.exe is designed for Windows 9X or NT4.0. So, it may very well not install correctly.
You'll probably need to setup your environmental variables yourself. If you're using an IDE, you need to manually add JMF.jar to your list of project libraries.

RTP (UDP) multicast stream with JMF...?!

Hi.
I am quiet new in the material of jmf and its plugins. I have a network which offers me an UDP stream (mpeg2 or mpeg4 both could be available). I can watch this stream with an freewareplayer called VLC.
When using the JMF Studio tool, I can't watch the stream ... The Player is waiting for signals and breaks after 60 seconds. So, okay ... Maybe the JMF doesn't bring the right codec with it.
Now I've installed jffmpeg, but that doesn't help a lot. I write done the JAR File in Classpath and installed the Plugin, MimeType and Demultiplexer (as described) in the JMF Registry. The behaviour of JMF Studio is the same. Does anybody have an idea wether jffmpeg supports this kind of streaming
and/or what I can do to get the stream?! Maybe there is an better Plugin for my solution.
I can't suppose that nobody here ever tried to get an Mpeg2 or Mpeg4 multicast stream with JMF. There must be an solution.
Many thanks for your help and reply!

Hi funnyjanni,
May be I am writing this after 4 years.
I am also in the stage when you faced the same problem. You might have found the solution to this.
Please help me on this. I am trying to use jffmpeg to play UDP mutlicast stream.

Play sdp file with JMF

Hi,
I have a Darwin Streaming Server(DSS) running on a machine, that reflects several broadcasts from other machines (I'm broadcasting to the DSS with JMF).
I can see all the videos and audio without any problem with Quick Time, but I can't find a way to play the sdp files with jmf. I've searched the web for jmf and sdp, and there isn't much information, i've also tried to play with JMStudio..no luck. In the JMF solution there aren't any samples for SDP files....
If I can't find a way to do it, I'll use Quick Qime 4 Java, the only problem is that there isn't a linux implementation :(
Thanks in advance.
Best regards,
ANeto

Hi,
I have read all the mails on the JMF interest group regarding the Broadcaster and DSS.
Well i too am trying to do a similar application. This is an Application
Casting program basically to share my desktop with the other person sitting
across the network using my client. And in order to multicast this, i am
looking at using Darwin Streamng Server.
The whole idea here is that i break the desktop image up into frames and
then compress them and then send it over, protocol used here is TCP/RTP/UDP.
I am trying to hit this stream of packets to DSS so that it can be accessed
else where over the internet. I'm trying to under stand the basic
authentication mechanism DSS uses, so that i can create the .sdp file and
transfer it over to the DSS, which can further be accessed by any client
that can understands sdp.
As i read in the mail some of you were able to create the .sdp file with your custom built boradcaster and send it to DSS if i am not wrong.
I have tried this with Mpegable Broad caster as you said.
Now the problem i had was to create .sdp file with my application and push it to the DSS.
So have you made some kind of a documentation or can you give me an idea as
to how i can go about this. Or it will be even better if you can share the code with me.

Capture cards to use with JMF....

Hello, I need to buy a video capture card to use with JMF in order to get a video signal and send it using a stream channel.
Somebody can help me and post a list of compatible capture cards with JMF?.
I think on buy a PINNACLE 500 PCI but i have read that it is incompatible with JMF.
Thanks.

Creative webcam live should work, most webcams will work... at least under Windows. I've 2 older creative webcams that work under Windows.
Not sure about Linux support though...
Ps. there's a Java Media Framework section of this forum, where all the JMF related questions should be posted.
