<p>Add multimedia to your application so that users can easily play their
content. Consume and share content with other devices attached to a system or
remotely over the network. The underlying low-level API is available if you
need more control.</p>

 <title>What can you do?</title>
 
  <p><em style="strong">Multimedia</em> in GNOME is built on the
  <em style="strong"><link xref="tech-gstreamer">GStreamer</link></em>
  framework. With GStreamer, flexible <em>pipelines</em> of media can be
  created, from simple playback of audio and video to complex non-linear
  editing.</p>

  <p>GStreamer uses
  <em style="strong"><link xref="tech-pulseaudio">PulseAudio</link></em> when
  outputting audio, and therefore can target many types of output hardware.
  PulseAudio also handles dynamic output switching and application-specific
  volume control.</p>

  <p>For <em style="strong">webcams</em>, use
  <em style="strong">Cheese</em>. It provides a simple
  interface to webcams connected to the system, and an easy way to add an
  avatar chooser to your application.</p>

  <p>Use <em style="strong">Rygel</em> to <em style="strong">share content over
  the network</em> to devices such as TVs and games consoles. Rygel uses
  <em style="strong"><link xref="tech-gupnp">GUPnP</link></em> underneath,
  which is a low-level API to access content with <em style="strong">UPnP</em>
  protocols.</p>

  <p>For simple <em style="strong">event sounds</em>, such as a shutter sound
  when taking a photo, use
  <em style="strong"><link xref="tech-canberra">libcanberra</link></em>, which
  implements the freedesktop.org sound theme specification.</p>
