Thanks again @dynamicdave.
I'm definitely being patient after pressing the recording button, but it stays permanently red. Within a second of pressing it I get a "Recording Done" message and when I look at the folders in the pi, I can see a new mp4 with a size of zero bytes. I need to press the button again to turn it back to green.
I found an error in the HSS Recording flow. The existing Catch node didn't seem to show the error anywhere in the app's UX, so I added some debug nodes and saw the command going to the Camera recording exec node was:
"ffmpeg -y -i http://212.30.240.7/mjpg/video.mjpg -t 5 -c:v h264_omx -pix_fmt yuv420p -vb 20M -r 10 /var/www/html/hss_media/recordings/10/10-46-13.mp4"
and the error directly from the Camera recording exec node was:

A possible clue to this error is that during the initial RPi setup, I had some troubles installing ffmpeg.
sudo apt install -y ffmpeg git
It flagged a handful of missing files and said to use --fix-missing. So I reinstalled with:
sudo apt install -y --fix-missing ffmpeg git
I didn't see any errors that time. I will look into the the libOmxCore.so not found errors.
Regarding your question about camera feeds, the only sample feeds that work are those from the French Bakery and Reykjavik Iceland.
I just created a hss_config.txt to use a local Tapo c100 camera. I modified the HSS initialization tab to use the new config file, but got no video in the app. (The URL is correct since it works in VLC.)
Does HSS support RTSP? If so, is the correct setting in hss_config.txt file "type": "IP cam" or is that just a free text field?
Also, from my previous post, does it seem correct that the mp4 files are being created by the app with only -rw-r--r-- 1 pi pi permissions / group?
