RTSP stream snapshots

I have an IP camera stream over RTSP. I want to consume that RTSP feed in a .Net Core C# app and generate JPEG snapshots. This .Net Core app is running on Ubuntu 18.04.

Are there any samples, tutorials or guides that address this? I have looked and nothing seems to fit the specific scenario I have.

I have installed the libvlc and libvlcsharp packages.
