I rebuild gst-omx with --enable-static-plugins.
At this step I have 3 file, .a .la .so inside directory: /lib/gstreamer-1.0 
But project doesn't build, because eclipse can't found -lgstomx. I move this file to directory: /lib
After this project builded and ran on device.

Just in case, my build output in attachment.

Previous problem was solved, thanks!) But now I have another one... 
At runtime, pipeline can't found element omxh264dec and other gst-omx elements.
I create pipeline with this code:
data->pipeline = gst_parse_launch("filesrc location=/sdcard/test.mp4 ! qtdemux ! h264parse ! omxh264dec ! eglglessink sync=0", &error);
And see error:
Unable to build pipeline no element "omxh264dec"

I try resolve this problem, and modify code from gst-inspect:
void printPluginsList() {
	GList* plugins; /* The head of the plug-in list */
	GList* pnode;   /* The currently viewed node */

	/* Empty the list out here */

	plugins = pnode = gst_registry_get_plugin_list(gst_registry_get());
	while(pnode) {
		/* plugin: the plug-in info object pointed to by pnode */
		GstPlugin* plugin = (GstPlugin*)pnode->data;
		__android_log_print (ANDROID_LOG_ERROR, "Plugins list", "%s", gst_plugin_get_name(plugin));
		pnode = g_list_next(pnode);
	}

	/* Clean-up */
	gst_plugin_list_free (plugins);
} 
As I understand, this function must print all plugins in registry... But in output I can't found omx or openmax.

How should I add gst-omx plugin to android project, so I can use it elements on  pipeline?
