NAME

gst-xmllaunch - build and run a GStreamer pipeline from an XML serialization

SYNOPSIS

gst-xmllaunch [OPTION...] XML-FILE [ ELEMENT.PROPERTY=VALUE ... ]

DESCRIPTION

gst-xmllaunch is a tool that is used to build and run a basic GStreamer pipeline, loading it from an XML description. You can produce the XML description using gst-launch-0.8(1) with the -o option or by calling gst_xml_write_file() in your own app.

A simple commandline looks like:

gst-xmllaunch my-pipeline.xml filesrc0.location=music.mp3

This sets the location property of the element named filesrc0 to the value "music.mp3". See gst-launch(1) for syntax on setting element names, and gst-inspect to see what properties various elements have.

You can pass "-" as the XML-FILE to read from stdin.

XML-FILE can be a URI as well, thanks to the wizardry of libxml. I'm not really sure what all is supported, it seems http works just fine though.

gst-xmllaunch accepts the following options:

--help: Print help synopsis and available FLAGS
--silent: Do not output status information
--exclude=TYPE, -XTYPE: Do not output status information of TYPE
