err... how do I go about reproducing this exactly ? 

I know it sounds a silly question, but what do I need to get exactly to get this
problem ?

Sorry for the delay in responding.  Media in OOo 2.0 is handled via the Java
Media framework, http://java.sun.com/products/java-media/jmf/2.1.1/download.html

When this is properly installed, you can play back certain video formats (MPEG-1
seems to work) embedded into the slide.  

These are the steps that I used previously to get movies playing in OOo 1.9.79
and 1.9.104 from the openoffice.org website.  With the Fedora OOo 1.9.104, the
movie played, but it openned its own window in the top left corner of the
screen.  I will test out the lastest Fedora OOo this weekend, to see if things
have changed.

# Install j2re and mozilla-j2re packages. 

# Make sure that java is in your path. In your .cshrc add:
setenv PATH /usr/lib/jre/bin/:$PATH

# Get the Java Media Framework and install it:
sh ./jmf-2_1_1e-linux-i586.bin
chown -R username:username JMF-2.1.1e
initialize things (even though the install script did it as well), by running
$JMFHOME/bin/jmfinit

# setup the JMF environment. Add to you .cshrc
setenv JMFHOME /home/username/JMF-2.1.1e/
setenv CLASSPATH
$JMFHOME/lib/jmf.jar:$JMFHOME/lib/mediaplayer.jar:$JMFHOME/lib/multiplayer.jar
setenv LD_LIBRARY_PATH $JMFHOME/lib:${LD_LIBRARY_PATH}
setenv PATH ${PATH}:$JMFHOME/bin
and then make the changes stick, source .cshrc

# now try running jmstudio in $JMFHOME/bin. This will pop up a little window, go
to the File menu and open an MPEG-1 movie and ensure that it plays.

# Fow what ever reason, things don't seem to respect the CLASSPATH, so copy all
the contents of the JMF lib/ directory into the JRE extension directory (as root):
cp $JMFHOME/lib/* /usr/lib/jre/lib/ext

# Now test things out in Mozilla, to ensure that the JRE sees the JMF stuff. Sun
has a diagnostic page for this. Go to JMF diagnostics and make sure that is says:
JMF Version... 2.1.1e

All Java Build
Native Libraries Found

If you don't see this, then OOo will not work either. Most likely, something was
not copied into the right directory in the step above.

# Get the latest Openoffice.org build, untar and install (skipping the
suse-menus RPM on a Redhat system).

# Launch Openoffice.org,
/opt/openoffice.org1.9.79/program/soffice
Go to Tools/Options/Java/Class Path and add $JMFHOME/lib and exit OOo.

# Now things should all be set. relaunch Openoffice.org and create a
presentation and try embedding movies.

I'll have a look, but the only difference between upstream OOo and our one in
tis area is that ours is built/run with gcj/gij so this will likely not be a
specific OOo issue, but rather some gcj thing

nah.., there's nothing I can do about this :-( 

Too many sun java components which we don't support involved in the process
which don't work with gcj yet. (caolanm->fitzsim: unless you want to give this a
once over from a gcj perspective...)

e.g. jmstudio with gcj and without sun-java gives..

At least this jmstudio error should be easy to fix.  I'll have a look. 
Reopening and reassigning.

*** Bug 178727 has been marked as a duplicate of this bug. ***

I can't click through the JMF license.  Is there any way you can reduce this to
a test case so that I don't need to download proprietary software to reproduce it?

Can someone retry this against Rawhide?  At least the null pointer exception
should have been fixed by the libgcj backport.

As for a long-term solution to the JMF problem, there is FMJ:

http://fmj.sourceforge.net/

Maybe someone could try OpenOffice's media support against FMJ.

caolanm->fitzsim: Our future plan here from the OOo side is to replace the java
avmedia stuff with a gstreamer implementation http://rodo.foo.cz/blog/?p=16 so
this jmf isn't a priority for me if you'd like to close it out.

Sounds good.  Let's leave this open until the gstreamer implementation hits
Rawhide, that is, until this bug is actually fixed.  Just curious: what's the
timeframe for that?

probably FC-7

Caolan, how is this looking for Fedora 7?

http://qa.openoffice.org/issues/show_bug.cgi?id=68717 there's a set of patches
in ooo-build but not upstreamed yet, though they look fairly good too me

REOPENED status has been deprecated. ASSIGNED with keyword of Reopened is preferred.

if you open http://people.redhat.com/caolanm/slideshow/videodemo.odp with the
current rawhide to-be-FC-7 OOo it should now work and play the video when you go
fullscreen
