Currently, if the user selects the "Trim Video" and after selecting the required trimming timings using sliders. The video in the player plays as usual.

So let us understand what are the changes required now if the video length is 5 min and the user mark his/her required trim timings using the slider, Instantly in the player, the video has to start playing from the new "From" time to "To" time.

As VideoCutTool is using react-video player this references might be helpful https://video-react.js.org/components/player/

Probably code changes should be done here: https://github.com/gopavasanth/video-cut-tool-front-end/blob/master/src/components/home.js
