Original commit message from CVS: * gst/auparse/gstauparse.c: (gst_au_parse_base_init), (gst_au_parse_class_init), (gst_au_parse_init), (gst_au_parse_reset), (gst_au_parse_add_srcpad), (gst_au_parse_remove_srcpad), (gst_au_parse_parse_header), (gst_au_parse_chain), (gst_au_parse_src_convert), (gst_au_parse_src_query), (gst_au_parse_handle_seek), (gst_au_parse_sink_event), (gst_au_parse_src_event), (gst_au_parse_change_state): * gst/auparse/gstauparse.h: Rewrite auparse to suck a little bit less: make source pad dynamic, so decodebin/playbin work with non-raw formats like alaw/mulaw; add query function for duration/position queries; check whether we have enough data before attempting to parse the header (instead of crashing when that is not the case); work around audioconvert sucking by swapping endianness to the native endianness ourselves for float formats; send initial newsegment event. Fixes #161712.
