protocol handlers would be nice to make different pipe scripts/commands a bit more managable. ie, add a new tab where you can create protocol handlers like

hls "ffmpeg -i %1 -c copy -f mpegts pipe:1"
lvst "livestreamer -O %1 best"
lvtc "livestreamer -O %1 best|ffmpeg -i pipe:0 -c copy mpegts pipe:1"
radio "ffmpeg -i %1 -vn -acodec aac -metadata service_provider=%2 -metadata service_name=%3 -mpegts_service_type digital_radio -f mpegts pipe:1

%1 would be the url-part after the protocol:// in the mux-config, %2 the MUX- and %3 the channel-name etc...
