[Paraview] Time animation: Paraview, Python, XDMF

[Guillaume]

Hi,

I try to run this script for test the possibility of animation with 
Python and Paraview:

#!/opt/Paraview/ParaView-3.12.0-RC2_python_MPI/bin/pvpython
from paraview.simple import *
import sys
reader = XDMFReader(FileName='Datas/HrsTest.xdmf')
Show(reader)
Render()
GetActiveCamera()
AnimateReader(reader,filename="movie.avi")
sys.exit()
#

But I get this error:

Traceback (most recent call last):
   File "./anim_time.py", line 8, in <module>
     AnimateReader(reader,filename="movie.avi")
   File 
"/opt/Paraview/ParaView-3.12.0-RC2_python_MPI/Utilities/VTKPythonWrapping/site-packages/paraview/simple.py", 
line 551, in AnimateReader
     return servermanager.AnimateReader(reader, view, filename)
   File 
"/opt/Paraview/ParaView-3.12.0-RC2_python_MPI/Utilities/VTKPythonWrapping/site-packages/paraview/servermanager.py", 
line 2163, in AnimateReader
     raise RuntimeError, "Saving of animation failed!"
RuntimeError: Saving of animation failed!

Please is somebody have an idea what is wrong ?

Thanks,
G
