Updated

Affected Software

2 affected components

Fraunhofer IIS fdk-aac

Fraunhofer IIS fdk-aac-free

Frequently Asked Questions

What maintenance work would be needed to keep the free variant aligned with newer upstream releases?

A maintainer would need to recreate the changes that turn fdk-aac into fdk-aac-free as a small rebasable patch series or a script that removes the unwanted components. This work may need to be repeated as upstream adds new algorithms.

What should trigger a renewed review of the free variant?

Major updates to fdk-aac should trigger a new patent-focused audit. New upstream algorithms may require additional components to be removed.
