NAME
gst-std-options - standard options available for most
GStreamer applications
DESCRIPTION
GStreamer standard options which are available for most
GStreamer based applications.
OPTIONS
The following options are supported:
--help-gst
Display GStreamer help options.
--gst-debug-disable
Disables debugging.
--gst-debug-help
Prints a list of available debug categories and their
default debugging level.
--gst-debug-level=level
Sets the threshold for printing debugging messages. A
higher level prints more messages. The useful range is
0-5, the default value is 0.
--gst-debug-no-color
GStreamer normally prints debugging messages so that the
messages are color-coded when printed to a terminal that
handles ANSI escape sequences. This option causes
GStreamer to print messages without color. Setting the
GSTDEBUGNOCOLOR environment variable achieves the
same thing.
--gst-debug=string
Specifies debugging levels for each category, where

string is a colon-separated list of categoryname=level
pairs. level is in the range 0-5 where 0 shows no mes-
sages and 5 shows all messages. The wildcard * can be
used to match category names. Use the --gst-debug-help
option to show category names.
Example: GSTCAT=5:GSTELEMENT*=3
--gst-disable-registry-fork
Disable the use of fork(2) when scanning the registry.
--gst-disable-segtrap
Disables trapping of segmentation faults during plugin
loading.
--gst-fatal-warnings
Causes GStreamer to abort if a warning message occurs.
--gst-plugin-load=plugins
Preloads the plugins specified in a comma-separated
list. Another way to specify plugins to preload is to
use the environment variable GSTPLUGINPATH.
--gst-plugin-path=path
Adds directories separated with ':' to the plugin search
path.
--gst-plugin-spew
GStreamer info flags to set Enable printout of errors
while loading GStreamer plugins.

--gst-version
Prints the version string of the GStreamer core library.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment
variables:
GSTDEBUG Comma-separated list of debug
categories and levels. Values are
the same as used with the --gst-
debug argument.
GSTDEBUGNOCOLOR When this environment variable is
set, colored debug output is dis-
abled.
GSTREGISTRY Path of the registry file. Default
is ~/.gstreamer-0.10/registry-*.xml.
GSTPLUGINPATH Specify a list of directories to
scan for additional plugins. These
take precedence over the system plu-
gins.
GSTPLUGINSYSTEMPATH Specifies a list of plugins that are
always loaded by default. If not
set, this defaults to the system-
installed path, and the plugins
installed in the user's home direc-
tory.
OILCPUFLAGS Useful liboil environment variable.
Set OILCPUFLAGS=0 when debugging
tools trip over liboil's CPU detec-
tion.
