Seeking not working with gstreamer built from sources

[clement]

Hello everyone,

I have recently installed gstreamer 1.8.3 from sources (I also have on my system gstreamer v1.2 installed from packages). For now, I can compile and link my application using gcc with the options : -I/path-to-gstreamer-1.8/include/gstreamer-1.0 -I/path-to-gstreamer-1.8/lib/gstreamer-1.0/include ... -L/path-to-gstreamer-1.8/lib/ -lgstreamer-1.0 ...
When I run the binary, I set LD_LIBRARY_PATH to /path-to-gstreamer-1.8/lib/ (if I don't, my application will use the system gstreamer), and everything works fine except the seek event. The same piece of code works with the gstreamer from packages but not with the one I installed.

What am I doing wrong ?

Thanks in advance,

Clement
