NAMEgst-xmllaunch - build and run a GStreamer pipeline from an XML serialization
SYNOPSISgst-xmllaunch [OPTION...] XML-FILE [ ELEMENT.PROPERTY=VALUE ... ]
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-0.10(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.
WARNINGgst-xmllaunch is deprecated and broken for all but the most simple pipelines. It will most likely be removed in future. Don't use it.
