As subject says, it's possible to encode AAC multithread?

Using fdk-aac on ffmpeg 3.4.x at the moment, but I can upgrade to 4.x or
switch aac encoder if it allows it.

ffmpeg -threads 0 -i input.mp3 -acodec aac -ab 96000 -ar 44100 -ac 2
test_encode.aac

...still uses a single CPU for the encoding process, and looking at fdk-aac
sources and documentation do not hint any multithread capabilities...

also googling around I only get forum posts that say both internal and fdk
encoder do not support multithread, is that true?
