How to set flac thread count in ffmpeg?

Is there a way to set the encoding thread count for the flac encoder in FFmpeg?
(Flac supports threaded encoding since v1.5)

If "-threads XX" option does not work i think it is only single threaded.

Here an old ticket still tagged as "open/wish"

If you have a GPU card, I warmly suggest you to use FLACL.

I got that too in Hybrid. Also added threading support when using flac directly, but I ideally I would also add it to when ffmpeg is used as encoder.
