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?

Maybe this?

Every instance of every such component was already running in a separate thread, but now they can actually run in parallel.

Good old RTFM lol

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?
