[vtkusers] vtkFFMPEGWriter.cxx fails to build in CentOS 7

[Robert Maynard]

The ParaView superbuild has an option for FFMPEG and it uses this version:

https://www.paraview.org/files/dependencies/ffmpeg-2.3.3.tar.bz2

I would start with seeing if you can get that to build. You can find
what options we build ffmpeg with at:
