[Paraview] Why is pvbatch displaying images?

[Pradeep Jha]

just wondering, when I was making OSMesa, it gave me the following message
during "configure":

------------------------------------------------------------------------------------------------------------
Project MESSAGE: Disabling video due the lack of GLib/Gio/GStreamer
------------------------------------------------------------------------------------------------------------

is it ok? Or do I need to do something about it?
