Description
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 “boundary” property otherwise it will be autodetected.
