Original commit message from CVS: * gst/asfdemux/gstasfdemux.c: (gst_asf_demux_init), (gst_asf_demux_loop), (gst_asf_demux_process_file), (gst_asf_demux_process_data), (gst_asf_demux_handle_data), (gst_asf_demux_process_object), (gst_asf_demux_get_stream), (gst_asf_demux_process_chunk), (gst_asf_demux_handle_sink_event), (gst_asf_demux_handle_src_event), (gst_asf_demux_handle_src_query), (gst_asf_demux_change_state): * gst/asfdemux/gstasfdemux.h: You know Chimaira? "I - HATE - EVERYTHING". Yeah, that's what this feels like. I think we should set a new requirement for demuxers from now on to implement sane loop functions, data loops, query and seek functions before first commit into CVS. And this commit fixes all of the above.
