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 realtime streaming. 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.. -- Teemu 2011/12/6 Johannes Truschnigg <johannes@xxxxxxxxxxxxxxx>: > Hi there, > > On Tue, Dec 06, 2011 at 05:00:24PM +0200, Teemu Suikki wrote: >> Hi! >> >> I need a mp3 audio stream of live tv channels..
