Can't import opus audio track from mp4 file

Audacity 3 Help Forum Windows
1

I am using audacity 2.1.1 on Win 7. I have files that were muxed by ffmpeg 4.0.2 into mp4 containers. The audio tracks are Opus. I can’t import the audio into Audacity. I’m assuming that’s because Audacity is using ffmpeg 2.2.2 libraries on windows? If so any plans to build against a newer version of ffmpeg? I ended up using ffmpeg 4.0.2 again to extract the audio to wav for audacity, but it seems like this shouldn’t be necessary.

As a long term solution, we would like to include built-in support for opus.
We would also like to update FFmpeg and several other libraries.

However, we only have a very small development team and a lot of competing priorities, so for now the answer is to use a 3rd party tool to convert opus files to a supported format before importing into Audacity.
