[Paraview] error making animation

[Jeremy McCaslin]

Hello,

If I specify the fps to be 1, then the animation gets saved properly.
However, it doesn't look good because it takes too long to transition
between frames.  If I set the fps to 20, I get the following error:

  Generic Warning: In
/home/kitware/Projects/ParaView-3.10/source/VTK/IO/vtkFFMPEGWriter.cxx, line
211

Could not open codec.

 ERROR: In
/home/kitware/Projects/ParaView-3.10/source/VTK/IO/vtkFFMPEGWriter.cxx, line
514

vtkFFMPEGWriter (0xd421880): Error initializing video stream.

Does anyone know why this occurs?
