AMF_NOT_FOUND errors & Crash - Can't use Source Record (Radeon GPU)

[amandryka]

Hi all,

I've been using OBS for my zoom calls, and Source Record to record the zoom window with success for the last 4 months.
But for the last two weeks, OBS has been crashing and unable to record the zoom window.

Normal recording works fine though.

I'm on Windows 10 64 bits, with 5600X CPU and RX 5800 XT GPU, OBS just reinstalled and up to date.

A bunch of AMF_NOT_FOUND errors pop up when I launch virtual camera (which triggers Source Record), and they are also logged when I change any encoding parameter in global settings, or in Source Record settings.

Here is my log below and a sample of the AMF errors.

Okay, I started digging into AMF troubleshooting, and found instructions here: https://www.tfrecipes.com/details/aHR0cHM6Ly9ibG9naW5vcy5jb20vYW1kLWVuY29kZXItaW4tb2JzLw==/
Turned out the encoder setting was set to software in the Simple mode tab, which I didn't see since I had moved to the Advanced mode tab.
