------- Comment #12 from Tim-Philipp Müller  2006-04-26 17:25 UTC -------
The issue with the alaw/mulaw files here was that decodebin doesn't
automaticlly plug alawdec/mulawdec into the pipeline after auparse, as it only
investigates the first structure of the template caps, sees 'raw format', and
stops processing there. What decodebin does here isn't really correct, but it's
much easier to make auparse use dynamically created sometimes pads like all the
other parsers/demuxers:

 2006-04-26  Tim-Philipp Müller  <tim at centricular dot net>

        * 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.

The 64-bit float sample file won't play currently, but I am too lazy to add a
hack for that to auparse. This needs fixing in audioconvert IMHO, filed as bug
#339837.
