This is a very cool project. I'm still waiting on my own Raspberry Pi to start toying around too! > I'm seeing continuous 'we must catch up xx seconds!' log entries until it > finally hits 60 seconds and restarts the source, using aacplus encoder from a > playlist (containing a single mp3 file currently, though goal is to encode > live audio) streaming to an icecast server. > > Any tips on how to tune liquidsoap to use less CPU? > > I'm only really after live audio encoding from a connected USB audio > interface, and streaming to icecast. David is right, you should first try with no encoding, output.dummy or output.icecast(%wav, ...). The next encoder I have in mind is flac which I think does not use much CPU. After that, ogg. mp3 and aacplus are probably about the same. I am surprised, though, that one encoding process would be too much. You could also see if your problem could come from either the network connection or the sound card. In each case, it should be very easy to setup a script that has a dummy end for that, for instance: output.icecast(%mp3, ..., blank()) output.file(%mp3, ..., "/dev/null", ..) Etc.. Good luck, please let us know what bottleneck you identify..
