\fIgst\-launch\fP is a tool that builds and runs basic
\fIGStreamer\fP pipelines.
useful to make sure muxers create readable files when a muxing pipeline is
shut down forcefully via Control-C.

-.B \-o FILE, \-\-output=FILE
-Save XML representation of pipeline to FILE and exit (DEPRECATED, DO NOT USE)
+.B \-i, \-\-index
+Gather and print index statistics. This is mostly useful for playback or
+recording pipelines.
.TP 8
.B \-f, \-\-no\-fault
Do not install a fault handler
.TP 8
-.B \-\-no\-sigusr-handler
-Do not install signal handlers for SIGUSR1 (play) and SIGUSR2 (stop)

Print memory allocation traces. The feature must be enabled at compile time to
work.

Lists use this format: ( VALUE \fI[, VALUE ...]\fR )
-.SH "PIPELINE CONTROL"
-
-A pipeline can be controlled by signals. SIGUSR2 will stop the pipeline
-(GST_STATE_NULL); SIGUSR1 will put it back to play (GST_STATE_PLAYING).
-By default, the pipeline will start in the playing state.
-.br
-There are currently no signals defined to go into the ready or pause
-(GST_STATE_READY and GST_STATE_PAUSED) state explicitely.

\fBGST_REGISTRY\fR
Path of the plugin registry file. Default is
-~/.gstreamer-GST_MAJORMINOR/registry-CPU.xml where CPU is the machine/cpu type
+~/.gstreamer-GST_API_VERSION/registry-CPU.bin where CPU is the machine/cpu type
GStreamer was compiled for, e.g. 'i486', 'i686', 'x86-64', 'ppc', etc. (check
the output of "uname -i" and "uname -m" for details).

+\fBORC_CODE\fR
