Specify path for new plugin

[pchaurasia]

Folks,

I am looking to use an example plugin in gst-app. In order to specify path I
am using -

GstRegistry *registry;
registry = gst_registry_get_default();
gst_registry_add_path(registry, directory);


However I am getting -

/home/ubuntu/work/Internet/gst-template/gst-app/src/play.c:57: undefined
reference to `gst_registry_get_default'
/home/ubuntu/work/Internet/gst-template/gst-app/src/play.c:58: undefined
reference to `gst_registry_add_path'

Which library do I need to link for these symbols ? When I go to directory
where gstreamer-1.0 is installed and look for aforesaid symbols in all *.so
- I do not find anything ...

ubuntu@tegra-ubuntu:/usr/lib/aarch64-linux-gnu/gstreamer-1.0$ objdump -D
*.so | grep gst_registry_get_default

Do I need to build libs again from sources ?

Thanks

This is called gst_registry_get() in GStreamer 1.x.

You need to link to libgstreamer-1.0.so.

This will be in the library directory (e.g. /usr/lib/aarch64-linux-gnu)
*not* in the directory where GStreamer plugins are in
(/usr/lib/aarch64-linux-gnu/gstreamer-1.0).

Wrong directory. This only contains GStreamer plugins, libs are one dir
up.

Thanks Tim, I was able to move on with GST_PLUGIN_PATH.

Thanks
