Browse source 
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.
