AEPG built using C++ SDK enable multi-frame rendering

Hi all,

Iv'e got an After Effects "General Plugin" used as a custom encoder which encodes a video data to my custom output file format.

The plugin is defined as an AEGP, and I'm trying to investigate how can I use the new "Multi-frame Rendering" feature introduced in the latest After Effects versions.

I looked through the official docs, but found nothing but super generic instruction like "Third-party effects can enable support of Multi-Frame Rendering through the AE Effects SDK by setting the following PF_OutFlag:" or "Set the PF_OutFlag2_SUPPORTS_THREADED_RENDERING flag in GlobalSetup to tell After Effects that your
effect is Thread-Safe and supports Multi-Frame Rendering."

But no concrete example of how can I do it, like exact function calls that would mark my plugin as such that can be used with the MFR feature.

I do know though that I might have to refactor my plugin to be thread-safe, but just for the sake of the intital reasearch, can anyone please provide a concrete instructions of how to mark a plugin as such that can be used with the MFP feature?
