I'm not sure I understand. I've already been running ffmpeg from the command line and it's been using multiple cores but default. What's the difference, what's the new behavior?

before you could tell an encoder to run multiple threads, but everything outside of the encoder would run effectively single threaded.

now you (should) be able to have all the ffmpeg components, decoder, encoder, filters, audio, video, everything all run parallel

Oooo. Will it be automatic? Or do you need to pass a flag?
