    As far as I’m aware this is only for the cli version of ffmpeg and won’t affect the threading of codecs many of which were already multithreaded.

      I recently tried figuring out how to build ffmpeg with Nvidia codecs. I’m very new to ffmpeg and codec terminology. How is multithreading for the CLI different than the codecs?

        My understanding is some parts have to be done sequentially even though the parts themselves are multithreaded, now the different parts can all be done in parallel.

        Change the main loop and every component (demuxers, decoders, filters, encoders, muxers) to use the previously added transcode scheduler.

        The components are what they have parallelised.
