Any ideas?

Seems that AVBufferSinkParms was dropped from the API in 6.0. Weird, I saw no deprecation warning.

I'll check that and fix it, but as of yet you need to use FFmpeg 5 to build FFmpegfs.

That was an easy one... Just pull the latest version and try again.

Perfect! Builds, works. Thank you for handling this so quickly!
