ext/xine/: add input plugin wrapper. Playback from files, http, mms and cdda works.
Original commit message from CVS:
2004-02-22 Benjamin Otte <otte@gnome.org>
* ext/xine/Makefile.am:
* ext/xine/gstxine.h:
* ext/xine/xine.c: (plugin_init):
* ext/xine/xineinput.c:
add input plugin wrapper. Playback from files, http, mms and cdda
works.
* ext/xine/xineaudiodec.c: (gst_xine_audio_dec_chain):
remove leftover G_GNUC_UNUSED
* gst/asfdemux/gstasfdemux.c: (gst_asf_demux_process_stream),
(gst_asf_demux_identify_guid):
improve debugging output
