Hi John,
It has been a long time since I set up Red 5, so the details are a little hazy. I basically ran the installer and demos. Once done, I had a number of apps installed and have mostly used the vod one to provide streaming video via rtmp to all my Moodle installs. You can see the notes I worked from here: https://69.23.196.147/moodle36/mod/book/view.php?id=839&chapterid=2367
Ignore the security warnings as they are due to using a self signed security certificate for the https, and go to the site. Log in as guest.
NOTE: The site is one I am currently using for QA Testing for Moodle 3.6, and will probably be wiped out over this weekend as it has been severely thrashed during testing. I need to remove over 10k user accounts and a wipe out is just easier and faster.
