/**

+ * @short_description: Next-generation automatic decoding bin
*
+ * #GstBin that auto-magically constructs a decoding pipeline using available
+ * decoders and demuxers via auto-plugging.
+ *
+ * At this stage, decodebin2 is considered UNSTABLE. The API provided in the
+ * signals is expected to change in the near future.
+ *
+ * To try out decodebin2, you can set the USE_DECODEBIN2 environment
+ * variable (USE_DECODEBIN2=1 for example). This will cause playbin to use
+ * decodebin2 instead of the older decodebin for its internal auto-plugging.
