Plugin Development (Tutorial)

Plugin and library development
1

I am currently going through the rust plugin development tutorials. I started with part 1. When I get to the end of Plugin initialization I try to inspect the build. I receive:

Could not load plugin file: File "target/debug/libperf.so" is not a GStreamer plugin

I also built the plugins provided in gst-plugins-rs. I could not inspect them as well. I went ahead and setup a dev environment, and I get the same result.

POP_OS! 22.04
GStreamer versions 120.3 (OS Provided) and 1.24.1 (Dev env with rs=enabled)

What do I need to fix with respect to the entry point?

plugin_init is defined in my lib.rs file.

I figured it out. It was a naming issue with the resulting so file and what I had declared in the the cargo file.
