The following commit has been merged in the experimental branch:
commit 1642ee4337988523207ee8f30be9281e6919d95a
Author: Stefano Sabatini <stefano.sabatini-lala at poste.it>
Date:   Thu Dec 31 14:12:58 2009 +0000

    Deprecate and mark for deletion the function guess_stream_format(),
    and clone its code to ffserver_guess_format() in ffserver.c.
    
    guess_stream_format() is hackish since it relies on some undocumented
    properties of the name of the muxers (wich is currently only relevant
    for the ASF muxer), and has no use outside ffserver.c.
