about vdpau plugin in gst-plugins-bad

[kedahanzi]

hello,
i compile the newest gstreamer, 
i use gst-inspect to show all plugins, but i don't find any vdpau plugin.
then i cd to /usr/local/lib/gstreamer-0.10,  run "ls *vdpau*", the result is:
libgstvdpau.la  libgstvdpau.so, why is it?

i am be sure to install vdpau driver successfully.  configure log about vdpau is as follow.

configure:40161: *** for plug-ins: vdpau ***
configure:40203: checking for VDPAU
configure:40211: $PKG_CONFIG --exists --print-errors "vdpau"
configure:40214: $? = 0
configure:40430: result: yes
configure:40436: Found up to date VDPAU installation
configure:40452: *** These plugins will be built: vdpau
