For this project I will probably have to build a custom tool that uses
ffmpeg for transcoding. VLC might be a good place to start but the
codebase is pretty large if I have to customise it so it's probably faster
to start from scratch.

This project probably doesn't require realtime sample accurate sync but
the latency should be within 2000ms between audio and video streams and
also between master/client. Latency should be as low as possible with a
balance between cpuload and bandwidth management.
Has anyone benchmarked realtime transcoding on dual core arm devices with
