no element "filesrc"

[zhenfeng ren]

hello,everyone:
I want run Gstreamer on Davinci (dm6446).

I download gstreamer from:
http://focus.ti.com/dsp/docs/dspsplash.tsp?contentId=3100
When I run the "test_MP3.sh 1.mp3", there is an error:

ERROR: pipeline could not be constructed: no element "filesrc".

And when I run "gst-inspect", the information is below:
root@(none):/home# gst-inspect
staticelements: bin: Generic bin
staticelements: pipeline: Pipeline object
Total count: 1 plugin, 2 features

I set the environment as :
root@(none):/home# export
LD_LIBRARY_PATH=.:/home/opt/system_files_gstreamer:/home/opt/gstreamer/lib
root@(none):/home# export
GST_PLUGIN_PATH=/home/opt/gstreamer/lib/gstreamer-0.10/
root@(none):/home# export PATH=$PATH:/home/opt/gstreamer/bin

Anyone give some suggestions?

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.

Thanks,
Gireesh

Hi Zhenfeng Ren,

Please refer to the attached log.txt.

BTW, I hope you've compiled libxml as well while building the GStreamer
packages. As far as I know, gst-inspect won't work without libxml and, in
that case, you need to edit the gst-launch source file to manually load the
plugins.

Thanks,
Gireesh

hi,Gireesh:
LD_LIBRARY_LIB is not right. When I change LD_LIBRARY_LIB.
***@EVM:~# 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...

[***@EVM 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
[***@EVM lib]#

Thanks,
Gireesh

hi,Gireesh:
I set
LD_LIBRARY_PATH=/usr/lib:/home/opt/system_files_gstreamer:/home/opt/gstreamer/lib

Thanks,

[zhenfeng ren]

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.

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,

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 .

[g***@public.gmane.org]

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

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

Thanks,

hi,
There is some xml libraries:
[***@EVM lib]# ls | grep libxml
libxml2
libxml2.2
libxml2.2.6.16
libxml2.a
libxml2.la

[g***@public.gmane.org]

Hi Zhenfeng Ren,

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

Thanks,
