Gstreamer

Command line utilities:

gst-inspect [plugin]	either lists all avaliable plugins, or gives details about the specified plugin
gst-launch <pipeline>	runs a GStreamer pipeline

The plugins fall into 4 categories:

• gst-plugins-base
• gst-plugins-good
• gst-plugins-bad
• gst-plugins-ugly

Your system will probably only come with the base package, possibly the good as well.
