Pokester is correct about Relive not supported by APU graphics.
Here AMD Relive Guide which also shows which AMD GPUs support it: https://www.amd.com/en/support/kb/faq/dh-023
From AMD Relive FAQ: https://www.amd.com/en/technologies/radeon-software-gaming-media
Are there Video RAM requirements for using the Radeon Relive feature?
Yes, Radeon ReLive is not supported on systems with 2GB VRAM memory or less.
The above requirement is probably the reason APU graphics are not supported since the majority of APUs Graphics uses a maximum of 2 GB of vRAM.
Possibly on the newer APUs if they have more than Maximum of 2 GB of vRAM it might work, just guessing thou.
