Hi, I have been relaying a stream from the dabusb stream server (http://www.baycom.de/products/dabusb/) using icecast2. DAB-USB uses the MIME type audio/x-mpeg for its audio streams, which icecast 2 doesn't support. Fix is very easy - add the following couple of lines to format.c: else if(strcmp(contenttype, "audio/x-mpeg") == 0) return FORMAT_TYPE_MP3; On a pedantic note - shouldn't FORMAT_TYPE_MP3 be FORMAT_TYPE_MPEG_AUDIO ? I am in fact streaming MPEG Audio Layer 2. Cheers, nick.
