The video is working fine. Its because you are using IDM. Please open IDM and you will see a
Download option there ---> go to its options and you will see
filetypes. Here you will see a box where all the formats are
written just remove [MP4] from that list and then this you
will not see this error in the video player.
This image will help you out.
