Thanks folks. I had read the examples others tried, even copy/paste and modified. After your feedback, I tried to use the various examples as is (cargolaw, pandacam), but that didn't work either. So, I moved some of the settings around, HLS vs MPEG-TS and have been looking at log files. Oh, I set the max number of streams from whatever the default was to 2. AND, I had edited channel-id to a value that didn't match the very last item in the EXTINF line. Channel-id was cam, and that value after the comma was PANDACAM2. Once I made them match, the errors I got in the log changed.
Here's my current source text:

This is with Stream format set to MPEG-TS. If I switch to HLS format, Pandas work, but my local stream doesn't. Here's the log:
