I have the following RPMs installed: totem-mozplugin-2.16.3-1.fc6 totem-2.16.3-1.fc6 firefox-1.5.0.9-1.fc6 xine-0.99.4-10.lvn6 xine-lib-1.1.3-2.fc6 xine-lib-extras-nonfree-1.1.3-3.lvn6 gstreamer-plugins-base-0.10.10-1.fc6 gstreamer-plugins-good-0.10.4-1.fc6 gstreamer-0.10.10-2.fc6 gstreamer-ffmpeg-0.10.2-0.3.20061108.lvn6 gstreamer-tools-0.10.10-2.fc6 In Firefox, about:plugins says that totem-mozplugin-2.16.3-1.fc6 is claiming to handle files of type "audio/mpeg / MP3 audio / mp3", but in Firefox, when I click on a link to an MP3, I get an error message from Totem: "You do not have a decoder installed to handle this file. You might need to install the necessary plugins." This is the same error message I get if I try to use totem to play the file directly. I was puzzled why totem couldn't play mp3s when xine could, and I found that it's using the gstreamer backend. (There is no obvious way in the totem GUI to switch backends.) The upshot: The plugin package should not claim to handle file types that totem can't actually handle. As a workaround, I have uninstalled totem-mozplugin, so that I can use xmms to play mp3s.
(In reply to comment #0) > I have the following RPMs installed: <snip> > The upshot: The plugin package should not claim to handle file types that totem > can't actually handle. The plugin has no way of knowing whether there will be an MP3 plugin to handle the stream. I've added an item to the Totem FAQ: http://www.gnome.org/projects/totem/#faq > As a workaround, I have uninstalled totem-mozplugin, so that I can use xmms to > play mp3s. If there was a way to disable the plugins without uninstalling them, I didn't find it. https://bugzilla.mozilla.org/show_bug.cgi?id=19118 looks like it's still not implemented fully.
