|
* Test.
|
|
* By Andres Colubri
|
|
*
|
|
* This example shows how to create GStreamer pipelines using the GSPipeline object.
|
|
* Pipelines allow to connect different gstreamer elements (video sources, decoders, etc)
|
|
* in order to construct a video or audio stream. The command line tool gst-launch can be used
|
|
* to launch pipelines, and most pipelines specified with gst-launch can be used in GSPipeline,
|
|
* as the shown in this sketch.
|
|
* Some online material on GStreamer:
|
|
* http://www.cin.ufpe.br/~cinlug/wiki/index.php/Introducing_GStreamer
|
|
* http://www.twm-kd.com/computers/software/webcam-and-linux-gstreamer-tutorial/
