I have several Gstreamer 1.16 plugins at /usr/lib/aarch64-linux-gnu/gstreamer-1.0.
I have several Gstreamer 1.21 plugins at /usr/local/lib/aarch64-linux-gnu/gstreamer-1.0.
I have a custom Python "app" (that I cannot make changes to) running a pipeline with the rtpbin element from the libgstrtpmanager.so plugin file, which exists both in the 1.16 and 1.21 paths. Gstreamer is preferring the 1.16 version of the plugin, which is causing errors in my "app", as it is expecting some signal functionalities only available in the 1.21 version.
Other than deleting/hiding the 1.16 version of the file, how do I specify that Gstreamer should prefer the 1.21 version of the plugin?
I have tried exporting the paths to $GST_PLUGIN_PATH, with the 1.21 path first, but that did not work.
