Hi, gstreamer-devel:     I compiled gst-ffmpeg-0.10.5 on my PC with commands listed below:     ./configure --prefix=/usr --enable-libamr-nb --enable-libfaad --enable-nonfree     make     sudo make install       PS: I installed libamrnb & faad and gst-ffmpeg found them in configure stage.     After installation finished, I found libgstffmpeg.so cannot be loaded: eric@eric-desktop:~$ gst-inspect|grep ffdec (gst-inspect-0.10:23654): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstffmpeg.so': /usr/lib/gstreamer-0.10/libgstffmpeg.so: undefined symbol: Encoder_Interface_exit     Any ideas? Is this a bug or something is wrong with my configure options? Thanks for any suggestions. Eric Zhang
