JMF in Linux

Hi everyone
I'm an University Student from Chile and i have to do a security system using Webams, and i'm thinking to use JMF for that.
Well, lately i realized that JMF can't control more than one webcam video stream, so my questions are:
1.- this also happens using Linux??
2.- Are there any problems (like the one before) with JMF in Linux that i should know about before start programing???
Thanks.

Thanks wew64 for your answer!!!!
I think that i missed "in Windows" there...jejeje.....what i meant was that i've read that JMF in Windows can't handle multiple webcams because you can only work with one vfw device for virtual machine.
I've tried that, and when i access another webcam a window appears and ask me to choose the video device....i need to see the video streams from internet, so i have to find another way.
i Hope Linux doesn't have that problem!!!!.....ahyway, if anyone have a better idea, i'm opened for suggestions.
Thanx!!!.

Error installing jmf-2_1_1e-linux-i586.bin

h3. Hello,
h3.
I'm trying to install jmf-2_1_1e-linux-i586.bin on a Linux(centos 5.1) system. I get the results at the end of this post after accepting the license agreement. I haven't found anything on the web or the bug database that has been helpful. I'm really at my wits end and could use a helping hand.

Hey Eran,
I guess, you can find the solution to your problem here:
[http://forum.ubuntuusers.de/topic/jmf-java-media-framework/#post-1806940]
It works well on Ubuntu, but since the error on Ubuntu looks exactly the same as on Centos, I think it should work for you as well.

Cannot install JMF under Linux Mandrake 10

I simply cannot install JMF under the Mandrake 10 Official Linux distribution. I downloaded the jmf-2_1_1e-linux-i586.bin file and tried to execute it as root. It unzipped some files then showed me an error message about AWT and GTK+. I found a hack consisting of modifying the .bin file to have the PATH variable point to SUN JDK, the error does not show up, but the installation still does not work. In fact, the installation works, but the Diagnostics applet keeps telling me than class files are not present. My Mozilla 1.6 Java plugin is working and displaying the applet. My JMF lib directory does not contain sound.jar, such jmf.jar. I set the CLASSPATH and LD_LIBRARY_PATH according to the readme.html file. I would like to know if it is a compatibility problem with Mandrake 10, the 2.6 kernel or if JMF just DO NO work under Linux. In the latter case, JMF is a violation to the Java portability philosophy and I would never use it on my own initiative, just if I were asked to.
After the files are unzipped, I have the following warning and error messages.
Warning:
Name: HorScrollBar
Class: XmScrollBar
The specified scrollbar value is greater than the maximum
scrollbar value minus the scrollbar slider size.
JavaSound Capture Supported = true

java.lang.Error: Can't open video card 8
java.lang.Error: Can't open video card 9
Done.
Even if I do not have a working video capture card (I have an ATI All-in-Wonder 128 but it is not working under 2.6 kernel), JMF should work because some people do not have a video capture card. I also tried with the cross-platform ZIP file, but this one does not contain sound.jar either and the Diagnostics applet keeps complaining about missing class files. I tried to search on the Web for solutions to this problem or for a way to change the CLASSPATH used by the Mozilla Java plug-in (if it uses a different CLASSPATH than the one from the environment variable), but nothing, nothing. Is there a distribution from which JMF would work better than Mandrake 10? Or can JMF work only under Microsoft Windows or Sun Solaris? I also tried Blackdown, but a README file directed me to the Sun's page, nothing to download here about JMF.

well, your not the only one.
I have it working in Debian, and JDS.(JMF is setup automatically in JDS).(2.6.6 kernel)
I looked at the installation structure of JDS, and was able to duplicate what they did for Debian.
Maybe it will work for Mandrake two??
ok, all you have to do is copy or create soft links from your Mozilla directory, just like you did with the java plugin, and link to all the *.so files in JMF-2.1.1e/lib directory.
Should work.
I also read that not haveing the native files only matters if you are doing Capture. not play.
to get your ATI All-in-Wonder 128 to work, make sure you install the correct driver, and have it working under linux, then try it in JMSTUDIO

Re: Can I run JMF in linux without X

I've just installed JMF for Linux last night.
I have it working on a Win 98 system.
I "think" X-Windows loads the display drivers ? Not sure though.
I've an old ATI All-in-Wonder video capture card, and think I have to
upgrade from X Windows 11 Release 6, to a newer version to use the
new Linux Graphics drivers for my card under the Gatos project in www.Sourceforge.net.... ( For video-in capture, not necessarily video display )
Hope some of that vague information helps...
regards,
Owen

Yes, you can. However, you must have the Mac OS 9 System Folder installed on your hard drive.

How to install JMF in Linux

How to install JMF in Linux?

Thank you AndrewThompson64
You have done a great job.You are welcome.. but really, the only
'great' thing I did was a quick search on
'Java install linux'
to show that link (that I knew was around
here somewhere) at the top of the
search reasults!
Thanks for your interest to help me.You are welcome. :-)
Next time you get stuck, 'drop back by'* and
I'll show you some more clever search tips. ;-)
* ..but really, you will gain a lot if you simply
'lurk' around the forum and read other posts,
even as you are writing code..

Webcam detected but not enumerated. Logitec cam, JMF, GNU/Linux, v4l2

Hi,
I've been trying the whole day to get my "Logitech, Inc. QuickCam for DELL Notebooks" with Java Media Framework.
From searching the web and mainly the sun forums I kind of understand that JMF is not getting much attention from the developers.
Maybe I'm wrong. (I hope so)
I need to use something to capture video from a webcam on linux using java.
JMF uses v4l but, as the v4l people say on their site, v4l2 support of v4l is broken...
I downloaded the jmf-2_1_1e-linux-i586.bin, tried to run the programs, they run but the webcam is not listed for capture.
When I search for devices the program outputs: (jmfinit or the others from jmf package)
JavaSound Capture Supported = true
JavaSoundAuto: Committed ok
Name = v4l:UVC Camera (046d:08c6):0
Trying 4 320 240
Trying 15 768 576
java.lang.Error: Can't open video card 1
java.lang.Error: Can't open video card 9
Apparently the camera is detected but something else prevents it from being used.
I would say the v4l interface...
I can view correctly the output from my webcam using:
mplayer -fps 30 -tv driver=v4l2:width=640:height=480:device=/dev/video0 tv://
but if I change driver=v4l2 to driver=v4l it wont work anymore...
Is there a workaround? Am I missing something? because a few people were able to use it so why not me =)

JMF works on Linux? It is possible?
Thanks very much!!!

# Place the downloaded file jmf-2_1_1e-linux-i586.bin in the directory where you want to install JMF, for example /usr/lib
# Make sure that the java executable is in your PATH. Just try the command java -version to verify that.
# Start the installation with sh ./jmf-2_1_1e-linux-i586.bin. You will be asked if you want to permit recording from an applet, it is quite safe to say "yes" here, but you probably won't need it. Then you will be asked if you want to allow writing local files from an applet, here it is recommended to say "no". As JTVD is not an applet, it doesn't require any of these two permissions.
# After these questions have been answered, the installer creates a directory called JMF-2.1.1e, extracts the files from the archive and starts querying the video and audio devices it has found in order to create the JMF registry. This may take a moment. Errors like "java.lang.Error: Can't open video card 1" usually don't mean that there is anything wrong.
If you see the error "JMF-2.1.1e/bin/jmfinit: line 88: exec: java: not found", you just have to make sure that the java executable is in your PATH and then run JMF-2.1.1e/bin/jmfinit manually in order to build the registry. Without the registry, applications like JTVD will not be able to find any video or audio devices.
# To complete the installation, you should set the environment variables JMFHOME, CLASSPATH and LD_LIBRARY_PATH according to the JMF installation path you have chosen. If you for example have installed JMF to /usr/lib/JMF-2.1.1e, then you could add the following lines to your .profile:
export JMFHOME=/usr/lib/JMF-2.1.1e
export CLASSPATH=.:$CLASSPATH:$JMFHOME/lib/jmf.jar
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JMFHOME/lib
Please note, that JTVD does not require this, as you can set JMFHOME in the startup script jtvd, the script then takes care of the rest.

PLEASE, I need some help.

Using cinepak codec and JMF under linux mandrake

Hello,
I have a big problem using JMF under linux to read video files encoded with the Cinepak codec.
I don't know if i'm the only one in this situation, so if you are too please let me know :)
I tested my project under both windows and linux. Under Windows, no problem : the cinepak encoded file is read perfectly. Under linux, it doesn't work. Even if i try to read it with JMStudio. So i think it may be a problem of codec under linux, but it isn't because i can read the video file with a linux video player.
I don't know what to do and it's very important for my project that i can read cinepak under linux.
Thanks in advance for any help
Alex

Webcam works in JMStudio but not in JMF apps (Linux)

Hi everybody,
I have successfully installed the Linux drivers (it's a Logitech Quickcam Express), and registered the webcam with jmfregistry. It works perfectly in jmstudio, both if selecting the "capture" menu or just opening an url as "v4l://0".
However, I cannot succeed in creating a datasource for this camera in my application. I can get the MediaLocator of the device, its list of formats, but when calling to Manager.createDataSource(), a "NoDataSourceException" is thrown.
Any hint, please?
Thanks a lot in advance.

Hi again,
I have also tested the JMF code samples, e.g. VideoTransmit, and I get the same problem.
It seems that only jmstudio is capable of using the camera!!!
Help, please!
