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.

Sample pipelines

Here is a simple pipeline to demux a multipart file muxed with GstMultipartMux containing JPEG frames:

gst-launch filesrc location=/tmp/test.multipart ! multipartdemux ! jpegdec ! ffmpegcolorspace ! ximagesink

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).

the content in multipart files is separated with a boundary string that can be configured specifically with the "boundary" property otherwise it will be autodetected.

Element Information

GstMultipartDemux

typedef struct _GstMultipartDemux GstMultipartDemux;

The opaque GstMultipartDemux structure.

The "autoscan" property

  "autoscan"                 gboolean              : Read / Write

Try to autofind the prefix (deprecated unused, see boundary).

Default value: FALSE

The "boundary" property

  "boundary"                 gchararray            : Read / Write / Construct

The boundary string separating data, automatic if NULL.

Default value: NULL
