Hi Zhenfeng Ren,

Seems like your GST_PLUGIN_PATH is not correct. Please check if the  
following libraries are available under your GST_PLUGIN_PATH (ie  
/home/opt/gstreamer/lib/gstreamer-0.10)
libgstcoreelements.a
libgstcoreelements.la
libgstcoreelements.so

Otherwise, please find out the location of these libraries and export that  
path as your GST_PLUGIN_PATH.

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-plugin-coreelements.html#plugin-coreelements

Thanks,
Gireesh

I check again ,and these libraries are under GST_PLUGIN_PATH .

hi,Gireesh:
 LD_LIBRARY_LIB  is not right. When I change LD_LIBRARY_LIB.
root@...:~# gst-inspect

(gst-inspect-0.10:2425): GStreamer-WARNING **: GStreamer was compiled
against GLib 2.12.4 but is running against 2.6.1. This will cause
reference counting issues
/home/opt/gstreamer/bin/gst-inspect-0.10: symbol lookup error:
/home/opt/gstreamer/lib/libgstreamer-0.10.so.0: undefined symbol:
g_intern_static_string

So,next step is to solve the glib problem.
Thanks.

Hi Zhenfeng Ren,

Did you set LD_LIBRARY_PATH or LD_LIBRARY_LIB?

I guess, your problem would be solved if you set LD_LIBRARY_PATH to the  
location that contains
libglib-2.0.la
libglib-2.0.so
libglib-2.0.so.0

In my system, it's here...

[root@... lib]# ls /gstreamer/lib/ | grep libglib
libglib-2.0.la
libglib-2.0.so
libglib-2.0.so.0
libglib-2.0.so.0.1800.0
[root@... lib]#

Thanks,
Gireesh

hi,Gireesh:
I set

hi,Gireesh:
 I think I make a mistake .
The LD_LIBRARY_PATH should be
/home/opt/system_files_gstreamer:/home/opt/gstreamer/lib

SO, the old problem come.
root@...# gst-inspect
staticelements:  bin: Generic bin
staticelements:  pipeline: Pipeline object

Total count: 1 plugin, 2 features

Hi Zhenfeng Ren,

I suspect there is another glib on your system which is conflicting with  
the one under gstreamer/lib.
Please try this step and see if it works...

#export  
LD_LIBRARY_PATH=/home/opt/gstreamer/lib:/home/opt/system_files_gstreamer:/usr/lib

Thanks,
Gireesh

hi Gireesh:

You are right.
Now, the problem  still is  that  the gstreamer could not work.
I donot know  why "gst-inspect" find no plugin .

Do you have libxml?
Please check if you have these libraries under your LD_LIBRARY_PATH

[root@... lib]#
[root@... lib]# ls | grep libxml
libxml2.a
libxml2.la
libxml2.so
libxml2.so.2
libxml2.so.2.6.26
[root@... lib]#

hi,
There is some xml libraries:

libxml2
libxml2.2
libxml2.2.6.16
libxml2.a

Hi Zhenfeng Ren,

Then I don't know why your gst-inspect fails to find plugins, provided your  
GST_PLUGIN_PATH is correct.
