Original commit message from CVS: 2005-10-02 Andy Wingo <wingo@pobox.com> * configure.ac (GST_PLUGIN_LDFLAGS): Change to be like -base. * ext/flac/gstflacenc.c: Ported to 0.9. * ext/flac/gstflacdec.c (gst_flacdec_loop): Handle errors better. * ext/flac/Makefile.am: Add the GST_PLUGINS_BASE cflags and libs, and link to gsttagedit. Enable flacenc. * ext/flac/gstflacdec.c: Re-enable tag reading.
