To work around this, multiple outputs could be generated within a single FFmpeg command line, decoding the frames of a video once and sending them to each output’s encoder instance. This eliminates a lot of overhead by deduplicating the video decoding and process startup time overhead incurred by each command line. Given that we process over 1 billion video uploads daily, each requiring multiple FFmpeg executions, reductions in per-process compute usage yield significant efficiency gains.
In a WWDC 2011 session, Dan Schimpf explained some of the goals of the refreshed design for Aqua in Mac OS X Lion were “meant to focus the user attention on the active window content”. This sentiment was echoed by John Siracusa in his review of Lion for Ars Technica:
