  66 <p>
  67 MultipartDemux uses the Content-type field of incoming buffers to demux and
  68 push data to dynamic source pads. Most of the time multipart streams are
  69 sequential JPEG frames generated from a live source such as a network source
  70 or a camera.
  71 </p>
  72 <p>
  73 The output buffers of the multipartdemux typically have no timestamps and are
  74 usually played as fast as possible (at the rate that the source provides the
  75 data).
  76 </p>
  77 <p>
  78 the content in multipart files is separated with a boundary string that can
  79 be configured specifically with the <a class="link" href="gst-plugins-good-plugins-multipartdemux.html#GstMultipartDemux--boundary" title='The "boundary" property'><span class="type">"boundary"</span></a> property
  80 otherwise it will be autodetected.
