Install multimedia plugins for Opera 9 under Fedora 8 (i386 and x86_64)

There should be no problem to get multimedia plug-ins installed for Opera 9 under Fedora with a "full" i386 or x86_64 architecture installation.
In some cases, this post may help (Opera being "Mozilla compatible" as Firefox) with installation having i386 and x86_64 components.
Nevertheless, other situations may still need additional instructions to be performed.

It was my case with my installation: Opera 9.27 (i386), under a Fedora 8 x86_64 installation.
In particular, the gecko-mediaplayer package (replacing the mplayerplug-in one) was available only in x86_64 architecture. The nspluginwrapper method does not seem to work with Opera, so a i386 version of gecko-mediaplayer package is needed.
This is quick way to get it installed:
- get a i386 version, for instance browsing the livna repository online, or using yumdownloader under a i386 installation,
- install it using yum (it will install all the needed dependencies)
yum localinstall "gecko-mediaplayer-XXX.rpm"
- the i386 plug-ins might be installed under /usr/lib/mozilla/plugins

To enable plug-ins into Opera, follow the usual way:
- Menu Tools->Preferences->Advanced->Content->Plug-in options->Change path
- add the /usr/lib/mozilla/plugins path (or equivalent)
- valid, and then click "Find new..." button.

Close and launch again Opera.
You may use the -debugplugin option to get debug information about plug-ins.

Finally, under Opera, take a look to the "opera:plugins" information page to check if plug-ins are available.
