Can you do export GST_DEBUG=3 or 4  before gst-inspect-0.10 and check the debug messages. This may give you more clues about your problem.


You might also need to do a export GST_PLUGIN_PATH=/usr/lib/gstreamer-0.10/

Subject: [gst-devel] How to register my new plugin on Nokia 770?




Subject: How to register my new plugin on Nokia 770?


Hello all,





I have created a new GStreamer filter plugin (say ‘Wow’). I have the shared object ( for ARM9) sitting pretty in /usr/local/lib/gstreamer-0.10/.

Now, I have copied this to /usr/lib/gstreamer-0.10/ on the Nokia 770.


Nokia-770# gst-inspect-0.10 wow     is not working.

Nokia-770# gst-inspect-0.10 fakesrc ! wow ! fakesink   is also not working.





HOW DID I CREATE filter plugin for ARM9?


I have ‘scratchbox’ tool setup for cross compiling the GStreamer programs for ARM9.


These are the steps I followed:

  1. Downloaded /gst-template from CVS to chroot’ed login of scratchbox.
  2. Use make-element to create ‘wow’.
  3. I have edited gstwow.c,

                           Gst_element_register(…, “wow”,,,);

                           SGT_PLUGIN_DEFINE( ,, “wow”,,,);

                                                (As suggested by Trimurthulu! See below e-mail)

  1. Edit gst-template/gst-plugin/src/ to change plugin name.
  2. run /gst-template/gst-plugin/
  3. run /gst-template/gst-plugin/make
  4. run /gst-template/gst-plugin/make install

All the steps are successful and shared object is generated.






After copying the .so to /usr/lib/gstreamer-0.10/ on Nokia 770 , I set LD_LIBRARY_PATH=/usr/lib.  But gst-inspect is not working.



[Scratchbox-ARM:]> gst-inspect-0.10 wow     is not working.

[Scratchbox-ARM:]> gst-inspect-0.10 fakesrc ! wow ! fakesink   is also not working.

you have to fill the following to display the any plugin info
gst_element_register ()

    "player name", plugin_init, VERSION, GST_LICENSE, GST_PACKAGE_NAME,

 you just compare with any existing plugin ..
