* #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.
