How can I play same file name over and over again without using the loop?

[dhawalc]

I have a function that creates a video output file named output.mp4, it creates a new output.mp4 every 5 mins or so, I want to use this file as the video source for the broadcast, how do I achieve this in a way that it should play again everytime a new file is created. I tried using Python code but refresh the media source is not working for me, any help or pointers would be really helpful. Thanks for reading
