gst-xmllaunch – build and run a GStreamer pipeline from an XML serial‐
gst-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 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
gst-xmllaunch is deprecated and broken for all but the most simple
pipelines. It will most likely be removed in future. Don’t use it.
gst-xmllaunch accepts the following options:
–help Print help synopsis and available FLAGS
Do not output status information
Do not output status information of TYPE
Save XML representation of pipeline to FILE and exit
GStreamer info flags to set (list with –help)
GStreamer debugging flags to set (list with –help)
GStreamer info and debugging flags to set (list with –help)
GStreamer info flags to set Enable printout of errors while
loading GStreamer plugins
Add directories separated with ‘:’ to the plugin search path
