gst-launch-ext - Run a predefined GStreamer pipeline
SYNOPSIS
gst-launch-ext filename [filename...]
DESCRIPTION
gst-launch-ext is a tool that is used to run a basic predefined GStreamer pipeline. This application is only used as a quick test to
ensure proper working of codecs and GStreamer. It doesn't handle more advanced features like synchronisation.
All supported formats in GStreamer should be playable by simply typing:
gst-launch-ext filename
It will also print out the pipeline it uses, so you can customize it using cut and paste.
CONFIGURATION
gst-launch-ext can be configured by creating a .gst file in your home directory. This is a perl-style configuration file and can override
the defaults for audio and video output sinks.
Here is an example .gst file that implements the same defaults as hard-coded in the script :
$cfg{AUDIOSINK} = "osssink"; $cfg{VIDEOSINK} = "colorspace ! xvideosink";
You can change osssink to any of esdsink, alsasink, jacksink (if you have the plug-in), and you can change xvideosink to aasink or
sdlvideosink.
Other plug-ins might be used as well if GStreamer has them.

SYNOPSIS
gst-launch-ext-0.8 filename [filename...] [gst-std-options]
gst-launch-ext filename [filename...] [gst-std-options]
DESCRIPTION
gst-launch-ext-0.8 runs a basic predefined GStreamer pipeline, and prints the name of the pipeline. gst-launch-ext-0.8 is only used as a
quick test to ensure that codecs and GStreamer work properly. gst-launch-ext-0.8 does not handle more advanced features such as synchro-
nization.
OPTIONS
The following options are supported by gst-launch-ext-0.8 and gst-launch-ext:
gst-std-options Standard options available for use with most GStreamer applications. See gst-std-options(5) for more
information.
The following options are supported by gst-launch-ext only:
--gst-list-mm List found major/minor versions. This option displays the versions that are available.
--gst-mm=string Force major/minor version. This option enables you to specify a specific version to run, if you do not want to run the
default version.
--print Print wrapped command line. This option displays the command that will be run, and then runs the command.
OPERANDS
The following operands are supported:
filename The name of the GStreamer pipeline to run.
EXTENDED DESCRIPTION
gst-launch-ext-0.8 can be configured by creating a .gst file in your home directory. This PERL-style configuration file can override the
default values for audio and video output sinks.
The following example .gst file implements the same defaults as those hard-coded in the script:
AUDIOSINK = osssink
VIDEOSINK = ffmpegcolorspace ! xvimagesink
You can change osssink to esdsink, alsasink, or sunaudiosink, and you can change xvimagesink to ximagesink, aasink, or sdlvideosink. You
must have the appropriate plugin installed on the system to use the specified output sink. Other GStreamer plug-ins can also be used.
