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

 

Hello all,

 

 

MY ISSUE:

 

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

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

But,

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)

4.	Edit gst-template/gst-plugin/src/makefile.am to change plugin name.
5.	run /gst-template/gst-plugin/autogen.sh
6.	run /gst-template/gst-plugin/make
7.	run /gst-template/gst-plugin/make install

All the steps are successful and shared object is generated.

 

 

 

 

WHAT OTHER THINGS DID I CHECK?

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.

 

 

 

 

Hello Volter,

 

Please, let me know if you could resolve your plugin registration issue.

 

 

 

Thanks and regards,

Sharath

Hi,
you have to fill the following to display the any plugin info
GST_ELEMENT_DETAILS{}
gst_element_register ()

GST_PLUGIN_DEFINE (GST_VERSION_MAJOR,
    GST_VERSION_MINOR,
    "pluginname", 
    "player name", plugin_init, VERSION, GST_LICENSE, GST_PACKAGE_NAME,
    GST_PACKAGE_ORIGIN)

 you just compare with any existing plugin ..

Regards..
