  65 <p>
  66 The flacparse element will parse the header packets of the FLAC
  67 stream and put them as the streamheader in the caps. This is used in the
  68 multifdsink case where you want to stream live FLAC streams to multiple
  69 clients, each client has to receive the streamheaders first before they can
  70 consume the FLAC packets.
  71 </p>
  72 <p>
  73 This element also makes sure that the buffers that it pushes out are properly
  74 timestamped and that their offset and offset_end are set. The buffers that
  75 flacparse outputs have all of the metadata that oggmux expects to receive,
  76 which allows you to (for example) remux an ogg/flac or convert a native FLAC
  77 format file to an ogg bitstream.

  95  This pipeline converts a native FLAC format file to an ogg bitstream.
  96 It also illustrates that the streamheader is set in the caps, and that each
  97 buffer has the timestamp, duration, offset, and offset_end set.
