[Rhythmbox-devel] Can anyone explain this wierd gstreamer behaviour

[mike <mike bristolreccc co uk>]

I have built gstreamer/RB from HEAD against kernel 2.6 with no OSS
driver

However when I try to use gstreamer to play a file it looks and fails to
find oss ie:

this is with gstreamer set to alsa

gst-launch-ext-0.7 music/root/The_Clash/Sandinista__\(disc_2\)/05\ -\
Washington_Bullets.ogg
No configuration file /home/mike/.gst found.  You might want to create
one.
This is not an error, just a friendly reminder... Check the man page.
 
Running command-line
gst-launch-0.7 filesrc
location="music/root/The_Clash/Sandinista__(disc_2)/05 -
Washington_Bullets.ogg" ! vorbisfile ! osssink
