Make a video player like instagram

Hi, I have a project which helps people write a story post that contains text, images, and videos. We have tried implementing video like how Instagram video feed does but not able to execute it completely. How it works now : 1. People see an image thumbnail in the video feed post and a play icon in the middle. 2. User clicks on the video, video play till the end and stops How we want : 1. People when scrolling through posts which have a video, the video should autoplay like insta. 2. There should be a small volume button like insta on the video , initially set to mute , but people can click and chose it to be with sound. 3. After the video reaches end, it should show the video image thumbnail with the play button like it shows now.(We dont need infinite loop play like Instagram) PS: we strore videos on Amazon S3. Then when we upload we push url to our server. And fetch from there when we fetch posts on feed
