1. I'm not sure if I understand your question. Are you complaining that you can't broadcast Live Video on Facebook, using the AMD 18.12.2 driver?
2. FYI, on my NUC8i7HVK I've have installed the latest Edition 19.7.4 of Radeon Adrenaline Driver and Intel DCH Graphics Driver version 220.127.116.1158. On my computer, those driver are functioning well and I've didn't observed any anomalies. I tried the broadcast to Facebook and as far I can see, it is working.

4. The Intel DCH driver you may download here: https://downloadcenter.intel.com/download/29058/Intel-Graphics-Windows-10-DCH-Drivers?product=80939
5. Before you are going to install the latest graphics drivers, make sure to do the following:
5.1. Create System Restore Point. This will give you the possibility to restore your system to the state before installation, in case of some failure.
5.2. Update Bios to the latest version 0058 https://downloadcenter.intel.com/download/28953/BIOS-Update-HNKBLi70-86A-?product=126143
5.3. Update your Windows to version 1903
I was having an issue getting the latest AMD drivers to work. I'm currently using Radeon Software Adrenalin 2019 Edition 19.7.3 now. It didn't occur to me that I needed to search for it manually. I'm guessing the newer version you listed will work as well, I'm not sure how this wound up being such a struggle for me, it's like I had a mini stroke. Since the version I have is working I kind of just want to call it a day. Thank you for your help. I assumed it would all sort itself out with the auto-detect on either website, but I guess a manual search was required.
Oh I already took care of that awhile ago, knowing that this was an Intel product, the first thing I installed after Windows was the Intel Driver and Support Assistant. I thought maybe it should have an auto install option, but I'll take it for what it is now. I was a little disappointed about the lackluster support for the AMD drivers from both companies though, but it's not super awful, just a little daunting.
