gst-launch-ext - Run a predefined GStreamer pipeline


gst-launch-ext filename [filename...]


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.


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.
