How to provide a custom plugin to gstreamer in Android ?

[stic at free.fr]

Hello,

in the case I am trying to create a custom gstreamer plugin, how can I provide it to gstreamer in Android app ?
I didn't find how to provide a custom plugin to Android gstreamer. Gstreamer finds only plugins already available in the GST SDK.
I even tried to add the static library of custom plugin in the same path as the standard plugins (GSTREAMER_SDK_ROOT/lib/gstreamer-0.10/static) but I always have the following message when trying to provide the plugin : error: undefined reference to 'gst_plugin_testplugin_register'
(where testplugin is the name of my plugin)

Thanks a lot for any help :)
