gst-inspect-1.0

This is the Linux man page for the gst-inspect-1.0 tool. As such, it is very Linux-centric regarding path specification and plugin names. Please be patient while it is rewritten to be more generic.

Name

--help

Print help synopsis and available FLAGS

--gst-info-mask=FLAGS

GStreamer info flags to set (list with --help)

-a, --print-all
