gst-launch-ext-0.8
gst-launch-ext-0.8(1) User Commands gst-launch-ext-0.8(1) NAME
gst-launch-ext-0.8, gst-launch-ext - run a predefined GStreamer pipeline 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. EXAMPLES
Example 1: Launching a GStreamer Pipeline example% gst-launch-ext-0.8 filename EXIT STATUS
The following exit values are returned: 0 Application exited successfully >0 Application exited with failure FILES
The following files are used by this application: /usr/bin/gst-launch-ext-Executable to run a predefined GStreamer pipeline ATTRIBUTES
