Unwanted bottom whitespace

[sm2017]

Why there is a white space bottom of video? In the following image I set a green border to video and a red border to react-html5-camera-photo div

In both my project and https://mabelanger.github.io/react-html5-camera-photo/ there is a white space bottom video I tried to set margin:0 padding:0 , there is no way to remove it , I also delete all other elements there is no diff

Hello, it's look like that video element add some margin by default, the only way to remove it is by using display: block; to the video element. Do you have a solution ? : https://css-tricks.com/forums/topic/solved-unusual-bottom-margin-on-html5-video-element/
