By using this environment variable, we could use decodebin to let
GStreamer automatically find the best elements to get the streaming
decoded. It was disable by default, in an attempt to have a easy way
to test it.
Follow up patch will use Playbin to create the pipeline which does the
similar behavior but with less work to maintain the pipeline.
Remove this in a separated patch to reduce the code changes.
