Not OP, but I automate collecting public meeting data from various local agencies across the US. The below resources might be helpful. Public meeting video can be captured using yt-dlp (and if not made public, obtained with a FOIA request), archived, transcribed, etc. Sometimes there is an RSS feed, otherwise use an LLM provider as an extractor engine against the target datastore.
