HTML5 video with video.js not working in Safari

问题 I have a private website that hosts training videos using the HTML5 video tag and the video.js plugin. It was working in Chrome/Firefox/Safari up until last Spring, but now the videos no longer work in Safari. They work fine in Chrome and Firefox. I upgraded to the latest video.js v4.12 and v5 but that has not helped. You can view the broken code on this test page. http://dev.investja.org/videojs_problem2.html When you open the page and click on the video it works fine in Chrome and Firefox

Anything I am missing? var stream = new FileStream(path, FileMode.Open, FileAccess.Read); var result = new HttpResponseMessage(HttpStatusCode.OK) { Content = new StreamContent(stream) }; result.Content.Headers

问题 I've been trying to write a React Hook for handling steaming video captured from a users camera to an HTML Video Element. I'm having trouble working out the best way to handle initialising and de-initialising the camera and HTML Video Element. I have attempted to add a cleanup function at the end of my hook, but my attempts have ended up with the video re-initialising repeatedly or any number of other weird bugs. Really I'm struggling to work out how and why the cleanup function is being
