How can I add the gstreamer zbar plugin to the deepstream

How can I add the gstreamer zbar plugin to the deepstream. Is there any chance of adding zbar plugin in deepstream in future release.

For all open source gstreamer plugins, we are just using the ubuntu distributed version. If you want to add plugins which are not in the distribution version, you can build the open source gstreamer by yourself. The version is 1.14.1 for current latest deepstream.
