> ffmpeg and other media frameworks (Windows Media Foundation, Apple’s AVFramwork) only support static pipelines.

FFmpeg doesn't do “pipelines”. It's a library, not a framework.

It's also a command line tool, where you can design (limited) media graphs: sources, sinks, filters, encoders, decoders, muxers, demuxers. You don't express it as directly as gst-launch's pipeline syntax, but it's very much a pipeline.
