For example:

would create respectively:

# A pipeline named ''p2'' consisting on a single element (playbin), which is enough to do playback of a file
# A pipeline named ''p3'' consisting on an audio+video transport stream video recording.

This wiki describes the basics on how to interact with GStreamer pipelines. Specifically, how to create new pipelines, change their state, list existing pipelines and finally destroy them. You'll find that the family of commands used to interact with pipelines are prefixed with pipeline_<action>.

Create Pipelines

In order to create a pipeline use the following command: 

 pipeline_create name description
     Creates a new pipeline named after name using the description gst-launch syntax.

For example: &rArr; ''Gstd Commands:'' <syntaxhighlight lang="bash" line="line" style="background-color:lavender"> {{{1}}} </syntaxhighlight> [[Category:GStreamer Daemon]] would create respectively:

  1. A pipeline named p1 consisting on a simple videotestsrc display
  2. A pipeline named p2 consisting on a single element (playbin), which is enough to do playback of a file
  3. A pipeline named p3 consisting on an audio+video transport stream video recording.


Play Pipelines

Pause Pipelines

Stop Pipelines
