[vtkusers] vtkFFMPEGWriter has a fixed frame rate?

[yirui1210]

Hello,


I am using vtkFFMPEGWriter to write a video, no matter the frame rate I set, the output video is still 600 frames/sec. 

The code I used has been attached. Can anybody check the problem for me? Thank you so much.


Regards,
Rui
