I found this play list for the lua programming on wireshark ,

There are 5 videos in this playlist and each video is around 10 minutes duration . There is accompanying git bucket link to the pcap file used and lua code generated.

As a introductory videos they are very good.
I think the guy who uploaded this video is a professor , he has some other video for dynamic programming
