Fix for movie playback

Just a FYI

Symptoms:
You used to be able to play movies in SL, but now you always get missing plug-in errors no matter what gstreamer plug-in you have installed. (I use Debian Sid... but you might see this problem with newer Ubuntu and related distros.)

Problem:
This was a pain to find. I was looking at the errors in the console while i was trying to play movies. Then by pure accident I noticed this error while SL was starting up.

(gecko:14055): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstffmpeg.so': /home/johnnie/bin/SecondLife-i686-1.21.6.99587/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /usr/lib/libdirac_encoder.so.0)

AH HA! seems like gstreamer does not like the version of libstdc++.so.6 shipped with the viewer.

The Fix:

Simply remove whereyouinstalledSL/SecondLife-i686-1.21.6.99587/lib/libstdc++.so.6 so it will use the one shipped with your distro.


NOTE:

If your gstreamer error mentions text/html that is a "bug" in the Debian/Ubuntu packages of gstreamer... one of the gstreamer plug-in packages is not compiled with this option enabled for some reason. :/

Nice catch. Previous attempts to stop bundling our own libstdc++.so.6 ended in bloodshed, but I'll keep an eye on it.

This one has been a thorn in my side for some time now, thanks for tracking it down! I'm wondering if you could let the omvviewer folks know about this fix, because it might affect them as well. You might also want to update the SL Wiki about this; I seem to recall there was an entry about this; if not you could start it...
