Nicolas, thank you for bringing up this topic. My team is working on similar functionality: the event loop is the central point to integrate protocol, demux/mux, decoder/encoder, avfilter and avdevice to form a complete multimedia subsystem(like DirectShow or GStreamer). Without the builtin event loop, it is very hard to support it with a clean and elegant way outside FFmpeg:
1. Multiple streaming(either local or network) 2. Multiple devices(either capture, playback even Bluetooth A2DP/SCO) 3. Interact and coordinate between the components 4. Provide a system wide and easy used API to application We are very excited that the community is considering to provide the generic event loop support and want to make the contribution.
