    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.

    This is the best summary I could come up with:

    The long-in-development work for a fully-functional multi-threaded FFmpeg command line has been merged!

    FFmpeg is widely-used throughout many industries for video transcoding and in today’s many-core world this is a terrific improvement for this key open-source project.

    The patches include adding the thread-aware transcode scheduling infrastructure, moving encoding to a separate thread, and various other low-level changes.

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

    There’s a recent presentation on this work by developer Anton Khirnov.

    It’s terrific seeing this merged and will be interesting to see the performance impact in practice.
