# gst-launch-ext-0.8(1)

Run a predefined GStreamer pipeline

## NAME

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 :

AUDIOSINK = osssink VIDEOSINK = ffmpegcolorspace ! xvimagesink

You can change osssink to esdsink or alsasink (if you have the plug-in), and you can change xvimagesink to ximagesink, aasink or sdlvideosink.

Other plug-ins might be used as well if GStreamer has them.
