Ubuntu Wiki

This is a quick how-to.

Add info if you think is plausible (code lines would be cool for beginners).

1. First, install totem-xine (removing totem-gstreamer) 2. Install gstreamerX.X-plugins and gstreamerX.X-plugins-multiverse (take care with country laws) 3. Activate all gstreamer plugins (not always necessary)

# gst-register-X.X

4. Install mplayer and mplayer-plugin 5. Remove totem-mozilla-plugin

# mv -f /usr/lib/mozilla-firefox/plugins/libtotem_mozilla.a /usr/lib/mozilla-firefox/plugins/libtotem_mozilla.a_backup
# mv -f /usr/lib/mozilla-firefox/plugins/libtotem_mozilla.la /usr/lib/mozilla-firefox/plugins/libtotem_mozilla.la_backup
# mv -f /usr/lib/mozilla-firefox/plugins/libtotem_mozilla.so /usr/lib/mozilla-firefox/plugins/libtotem_mozilla.so_backup
# mv -f /usr/lib/mozilla-firefox/plugins/libtotem_mozilla.xpt /usr/lib/mozilla-firefox/plugins/libtotem_mozilla.xpt_backup
