multipartdemux

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.

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 GstMultipartDemux:boundary property otherwise it will be autodetected.

Sample pipelines

 gst-launch-1.0 filesrc location=/tmp/test.multipart ! multipartdemux ! image/jpeg,framerate=\(fraction\)5/1 ! jpegparse ! jpegdec ! videoconvert ! autovideosink

a simple pipeline to demux a multipart file muxed with GstMultipartMux containing JPEG frames.

Properties

boundary

“boundary” gchararray

The boundary string separating data, automatic if NULL

Flags : Read / Write / Construct

Default value : NULL


single-stream

“single-stream” gboolean

Assume that there is only one stream whose content-type will not change and emit no-more-pads as soon as the first boundary content is parsed, decoded, and pads are linked.

Flags : Read / Write

Default value : false
