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.
