= GStreamer support =

A plug-in for the GStreamer framework (see [http://en.wikipedia.org/wiki/Gstreamer here] for the Wikipedia overview) allows for playing multimedia files using the i.MX hardware codecs.

;gst-fsl-plugin
:openembedded/recipes/gstreamer/gst-fsl-plugin_1.9.0.bb
:Freescale GStreamer plug-in

In addition to the GStreamer plug-in, there are also patches applied to the GStreamer core.

== Command-line usage ==

The gst-fsl-plugin comes with a command-line player that is called ''gplay''. Simply supply the multimedia file as an argument to gplay. For more information, please have a look at the "Application Specification for gplay" document provided by Freescale at [http://www.freescale.com].

There's even a more low-level interface that can be used: ''gst-launch''. Here is an example:
 gst-launch filesrc location=avatar.mov ! qtdemux ! queue max-size-time=0 ! mfw_vpudecoder ! mfw_v4lsink disp-width=1024 disp-height=768
For more information, please refer to the "i.MX Linux Multimedia Framework User's Guide" available from Freescale at [http://www.freescale.com].

== Media player ==

The SBC Gnome demo image comes with the ''Totem'' media player. Totem exclusively uses GStreamer to play multimedia files (audio and video).

To start Totem, navigate to {{mp|Applications-->Sound & Video-->Movie Player}} in the Gnome menu.

If you are interested in which codecs are used in the background, start Totem from a Gnome terminal. Start playing any file and you can view a similar output in the terminal (look for the colored lines):
