I actually managed to get this working quite well, here is my externremux.sh:
echo -ne 'Content-type: audio/mpeg\r\n'
echo -ne '\r\n'
ffmpeg -f mpegts -i - -vn -acodec libmp3lame -ab 32000 -ar 44100 -ac 1
-f mp3 pipe:1
Nothing more needed really, simple is beautiful. :) However, there is
one huge problem. It takes ages to start streaming, and then the audio
is a full minute behind.. The start delay is fine, but I need more
I'm going to York UK tomorrow to watch Snooker UK Championship, and I
was planning to hear the finnish commentary from Eurosport. :D It's
pretty much useless if there is a minute delay..
