Error in open and playback

[Nobody/Anonymous]

I have a java application using JMF and Fobs4JMF 4.1.

When opening a mpeg2 video I get:

When playing a movie I get:

I have two computers, one I developed on and one I am testing deploying on. I took all the class/jars/.property files I need and put them on a shared drive on the network. I then wrote a batch file like this:

------------------------------------------------------------------
set CLASSPATH=.;swing-layout-1.0.jar;nddsjava.jar;AbsoluteLayout.jar;sound.jar;customizer.jar;jmf.jar;mediaplayer.jar;multiplayer.jar;fobs4jmf.jar;
set PATH=.;./i86Win32j2sdk1.3;./i86Win32VC60;fobs4jmf.dll;
echo %CLASSPATH%
C:\Windows\system32\java Main
------------------------------------------------------------------

On the computer I developed on, I can click on this batch file and everything runs fine, with no errors. On the deployment computer I receive all the errors I've pasted above. It also plays the file much too quickly. For the life of me I can't figure out what could possibly be different between the two machines. They are both running the same version of java:

C:\Documents and Settings\u90767>C:\windows\system32\java -version
java version "1.5.0_09"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_09-b03)
Java HotSpot(TM) Client VM (build 1.5.0_09-b03, mixed mode)

Just to sanity check, I did install using the windows installer for Fobs4JMF on the deployment computer, and this has had no effect. However, the JMFStudio player will play these clips without any problem and at the right speed.

What could I be missing?

Thanks,

Sorry, an correction on the output from opening the file. Some got pushed off the console and I didn't notice it. This is the full output from the point the application was launched to the point that the movie was loaded, but before it began playing:

I still don't know why this would be working on one computer and not the other, but I found a fix after reading through the forum.

Here is an example of my code for opening a player:

        com.omnividea.media.protocol.file.DataSource ds = null;
        MediaLocator locator = null;
        locator = new MediaLocator(mediaURL.toString().replace("%20", " "));
        ds = new com.omnividea.media.protocol.file.DataSource();
        ds.setLocator(locator);
        mediaPlayer = Manager.createRealizedPlayer( ds );

Note that you can not use the DataSource(MediaLocator) constructor, or else you will get an exception about it already having a locator (I assume this is a bug).

The important things I did differently was replacing "%20" in the URL with a true " ". Also, I used the omnividea DataSource and passed that to Manager.createRealizedPlayer instead of using the Manager.createRealizedPlayer(MediaLocator) method.
