Although there is a playback bar allowing seeking displayed on the main website, I can't get it to come up.  Nothing I do in the mplayerplug-in.conf seems to help. 

I've found the arrow skipping functions, but no fast-forward, pause, or slow-motion.  Worse, I've installed the plugin for my pointy-clicky sister, and she will probably never learn the keyboard shortcuts.

How do I make the buttons appear?

Couple of questions? How did you install the plugin? did you install from source or a package? If you installed a package are you using Debian? If so then you will need to install from source as the Debian packager chose to disable the GUI.

Duh, I ought to know to add those details by now.  Yes, I'm running Debian Unstable; I'll "use the source". 

Thanks!

Where should I change so that it will enable gui in debian-package? thanks.

Compile from source, I don't know of a work around to fix the debian package

I'm having the same problem.  First, let me explain that I'm using Suse 9.2 Pro, and previously I had mplayer installed from source and mplayerplugin installed from RPM.  I had controls then.  But I also had browser lockups when playing media.  So I blew away the system (format/reinstall) and compiled both mplayer and mplayerplugin from source using the instructions found on the mplayerplugin page and the README/INSTALL files.   Mplayer works great. Mplayer plugin seems to play everything now.  My problem is that the mplayerplugin has no gui/progress bar/control bar.  It plays media wonderfully, but if I happen to hit a page with more than one embedded media, they all play simultaneously and I have no way of stopping anything.  Someone suggested that I right click on the movie and click on 'stop' or 'show controls', but while r-click works on the web page, there is no context menu when I r-click on the media.  It has also been suggested that the code in the page may be preventing the plugin from displaying controls.  Nope.  I'm writing the code and I am not disabling controls.   Further, I have no controls on the plugin test page recommended on the mplayerplugin homepage.   So, is there an mplayerplug-in.conf  option I can set to enable-controls?  Is there a configure option not listed in the README/INSTALL/Web Page that will tell the source to enable the gui?  Thank you for any assistance.

To enable the GUI you need to have the GTK development libraries installed so that mplayer can compile GTK support in.

If you want you can post the output of the ./configure command here. And that should confirm it.

Here is the output of ./configure  with no options run from the source directory from which I installed the plugin.

Thanks again.

Ok, that looks good. So the make command runs ok? What  is the result of this command

ldd mplayerplug-in.so

Oddly enough, I get the exact same message as a standard user and as su:

Ok well you are not getting gtk2 linked to the plugin so I want you to follow these steps

make clean
./configure --enable-gtk2
make
ldd mplayerplug-in.so

At this point you should see lib-gtk in the list.
If you do not then something is wrong with your gtk2 development package.

Excellent...
