command line describing the bin
whether to automatically create ghost pads for unlinked source or sink pads within the bin
a parse context allocated with gst.parse_context.ParseContext.new_, or null
parsing options, or #GST_PARSE_FLAG_NONE
a newly-created element, which is guaranteed to be a bin unless #GST_PARSE_FLAG_NO_SINGLE_ELEMENT_BINS was passed, or null if an error occurred.
This is a convenience wrapper around gst.global.parseLaunch to create a #GstBin from a gst-launch-style pipeline description. See gst.global.parseLaunch and the gst-launch man page for details about the syntax. Ghost pads on the bin for unlinked source or sink pads within the bin can automatically be created (but only a maximum of one ghost pad for each direction will be created; if you expect multiple unlinked source pads or multiple unlinked sink pads and want them all ghosted, you will have to create the ghost pads yourself).
