unregistered plugins problem on embedded platform

[na]

Hello,

I'm trying to run a gstreamer application on an embedded platform with an ARM processor.  I have managed to install everything without any error messages, however it looks like the plugins that I have installed are not being registered.

When I run  the application it is not able to create elements other than "bin" and "pipeline" and is not able to find the "registry.arm.bin" file (gst-inspect also only shows these 2 elements ). See below:

Some relevant files on my file system:

In /lib:
libgstapp-0.10.la
libgstapp-0.10.so
libgstapp-0.10.so.0
libgstapp-0.10.so.0.19.0
libglib-2.0.la
libglib-2.0.so
libglib-2.0.so.0

libgstreamer-0.10.la
libgstreamer-0.10.so
libgstreamer-0.10.so.0
libgstreamer-0.10.so.0.23.0

In /lib/gstreamer-0.10:
libgstapp.la    
libgstapp.so    

All the relevant libraries appear to have been built and installed on the target. However, gstreamer doesn't seem to be aware of it.

The Libraries and Includes in my makefile are as follows:

LIBS = -L${FILESYS_PATH}/lib -lglib-2.0 -lgstbase-0.10 -lgstreamer-0.10 \
-L${FILESYS_PATH}/lib/gstreamer-0.10 -lgstapp-0.10

INCLUDES = -I. \
-I${FILESYS_PATH}/include  \
-I${FILESYS_PATH}/include/glib-2.0 \
-I${FILESYS_PATH}/lib/glib-2.0/include \
-I${FILESYS_PATH}/include/gstreamer-0.10 \
-I${FILESYS_PATH}/usr/local/include/gstreamer-0.10 \
-I${FILESYS_PATH}/usr/local/include/gstreamer-0.10/gst

The configure options that I used for compiling things are as follows:

Liboil:

./configure --prefix=${FILESYS_PATH} --exec-prefix=${FILESYS_PATH} --host=arm-linux --build=i386-linux --target=arm-linux --disable-static --with-html-dir=/tmp/dump

Glib:

 ./configure --prefix=${FILESYS_PATH} --exec-prefix=${FILESYS_PATH} --host=arm-linux --cache-file=wham.cache --disable-selinux --disable-xattr --disable-gtk-doc --disable-static --with-html-dir=/tmp/dump

GStreamer:

./configure --prefix=${FILESYS_PATH} --exec-prefix=${FILESYS_PATH} --host=arm-linux --build=i386-linux --target=arm-linux --disable-nls --disable-static --enable-binary-registry --disable-loadsave --with-html-dir=/tmp/dump

Base Plugins:

./configure --prefix=${FILESYS_PATH} --exec-prefix=${FILESYS_PATH} --host=arm-linux --build=i386-linux --target=arm-linux --disable-x --disable-xvideo --disable-xshm --disable-gst_v4l --disable-alsa --disable-cdparanoia --disable-gnome_vfs --disable-libvisual --disable-ogg --disable-oggtest --disable-pango --disable-theora --disable-vorbis --disable-vorbistest --disable-freetypetest --disable-examples --libdir=${FILESYS_PATH}/lib --includedir=${FILESYS_PATH}/include --disable-nls --disable-static --with-html-dir=/tmp/dump


Any help appreciated.

Thanks.

Best regards,

It looks like the gstreamer was installed in a non-standard location.  The problem was solved by setting the GST_PLUGIN_SYSTEM_PATH variable and pointing correctly.
