| <p> |
| MultipartDemux uses the Content-type field of incoming buffers to demux and |
| push data to dynamic source pads. Most of the time multipart streams are |
| sequential JPEG frames generated from a live source such as a network source |
| or a camera. |
| </p> |
| <p> |
| The output buffers of the multipartdemux typically have no timestamps and are |
| usually played as fast as possible (at the rate that the source provides the |
| data). |
| </p> |
| <p> |
| the content in multipart files is separated with a boundary string that can |
| 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 |
| otherwise it will be autodetected. |
