The utility creates and runs a gstreamer pipeline which is configured through command line arguments\&. The syntax for the pipeline description is the same as for gst\-launch\&. The sole purpose of this program is that it allows to set the app\-name which will get used for example by xvimagesink to set the window title\&. This is needed for sydra to tell a tiling window manager where a window should be shown\&. +.SH "OPTIONS" +.sp +The following options can be passed to the \fBsydra\-launch\fR daemon: +.sp +\fBglobal options\fR +.PP +\fB\-D, \-\-nodaemonize\fR +.RS 4 +This option instructs +\fBsydra\-launch\fR +to run in foreground instead of becoming a daemon which is the default\&. +.RE +.PP +\fB\-u, \-\-username \fR +.RS 4 +run as this user\&. If no group is specified (\fB\-g\fR) the default group of the user is used\&. The default is to not drop privileges\&. +.RE +.PP +\fB\-g, \-\-groupname \fR +.RS 4 +run as this group\&. If no username is specified (\fB\-u\fR) this gets ignored\&. The default is to not drop privileges\&. +.RE +.PP +\fB\-C, \-\-chroot \fR +.RS 4 +Instruct +\fBsydra\-launch\fR +to run in a chroot jail\&. The default is to not run in chroot\&. +.RE +.PP +\fB\-P, \-\-write\-pid \fR +.RS 4 +Instruct +\fBsydra\-launch\fR +to write it\(cqs pid to this file\&. The default is to not create a pid file\&. +.RE +.PP +\fB\-L, \-\-log :[,[,[\&.\&.]]]\fR +.RS 4 +add log target to logging system\&. This can be invoked several times in order to log to different targets at the same time\&. Every target has its own log level which is a number between 0 and 5\&. Where 0 means disabling log and 5 means debug messages are enabled\&. + +The file target can be used more than once with different levels\&. If no target is provided at the command line a single target with the config +\fBsyslog:3,sydra\-launch,daemon\fR +is added\&. + +The following targets are supported: +.PP +\fBsyslog\fR +.RS 4 +log to syslog daemon, parameters [,[,]] +.RE +.PP +\fBfile\fR +.RS 4 +log to file, parameters [,] +.RE +.PP +\fBstdout\fR +.RS 4 +log to standard output, parameters +.RE +.PP +\fBstderr\fR +.RS 4 +log to standard error, parameters +.RE +.RE +.PP +\fB\-U, \-\-debug\fR +.RS 4 +This option instructs +\fBsydra\-launch\fR +to run in debug mode\&. It implicits +\fB\-D\fR +(don\(cqt daemonize) and adds a log target with the configuration +\fBstdout:5\fR +(logging with maximum level)\&. In future releases there might be additional output when this option is supplied\&. +.RE +.PP +\fB\-n, \-\-appname \fR +.RS 4 +This set the application name using +\fIg_set_prgname()\fR\&. It will be used for example by xvimagesink for window title\&. +.RE +.PP +\fB\-p, \-\-pipeline \fR +.RS 4 +A gst\-launch\-style description for the pipeline to get started\&. This uses the same syntax as gst\-launch\&. Example: +\fIvideotestsrc ! video/x\-raw,format=I420,width=864,height=480 ! xvimagesink\fR +.RE +.SH "BUGS" +.sp +Most likely there are some bugs in \fBsydra\-launch\fR\&. If you find a bug, please let the developers know at equinox@spreadspace\&.org\&. Of course, patches are preferred\&. +.SH "SEE ALSO" +.sp +\fBgst\-launch\fR(1) +.SH "AUTHORS" +.sp +Christian Pointner +.SH "COPYING" +.sp +Copyright (C) 2014 Christian Pointner\&.
