Splitmuxsink in DeepStream 4.0.1

Hi,
I am trying to implement the splitmuxsink in DeepStream because my project needs to store video files periodically. I have gone through this https://devtalk.nvidia.com/default/topic/1052840/deepstream-sdk/can-deepstream-3-0-dump-video-periodically/post/5347181/#5347181
But I just cant seem to find [qtmux ! filesink] in the mentioned file.

Is there a workaround to be able to save video files periodically in my a deepstream app?

Thanks,
Marmik.
