Due to its sloppy container, MPEG audio formats are not easy to
autodetect. Initially, Liquidsoap was trying to autodetect formats by
trying to decode them. However, this was not a good solution for MPEG
formats.
The first improvement we added quite a long time ago was to add
support for libmagic, which has a quite good detection of file
formats. Recently, we finally decided to also use file extensions.
Most likely, you have a liquidsoap binary that is not compiled against
ocaml-magic. If this is the case then you should get away with this
issue by recompiling with ocaml-magic enabled. Ocaml-magic is not
provided by us, it is autodetected a configure if it is installed on
your system.
If ocaml-magic is no help, then you could try a more recent liquidsoap
(1.0 beta1 or SVN) which will force mp3 detection for files with .mp3
extension :)
