GStreamer recipes' short trip

This section is not intended for a full walkthrough of GStreamer, its recipes, and other information required to grasp multimedia application development using GStreamer. Instead, we intend to have a look at different recipes, find BitBake elements in them, and discuss those elements. If we observe the order as we encountered in the gaku recipe, first of all, we set GStreamer in DEPENDS. Here are the main recipes for GStreamer:

• gstreamer_0.10.36.bb
• gst-plugins-base_0.10.36.bb
• gst-meta-base_0.10.bb
• gst-plugins-package.inc
• gst-plugins.inc

These can be found under meta/recipes-multimedia/gstreamer/. We don't have the luxury of enough pages to go into the details of each of these, and the relationships of each with the other. Hence, we will discuss the common constructs found in these files.

Types of variable assignments
