I'm also building, or trying to, a client for Reddit made with React. The thing I'm not achieving is properly rendering videos hosted on Reddit.<p>I've come to the conclusion that it's impossible. It's totally closed from being played outside of reddit.com by using CORS. I can't in any way play the DASH or HLS files from reddit.<p>I can load the mp4 fallback, but guess what? It's a video without audio. You can get the audio, but it's not documented anywhere (found on stackoverflow, I think). But of course, playing two files at once and syncing them is bound to break, specially on slow networks.<p>For a website dedicated to sharing stuff from all around the web (reddit didn't even have image hosting until a few years ago), it is really a dick move that you can't share stuff from reddit elsewhere.<p>It's a shame. Reddit is merely a shell of what it used to be, sadly.<p>Edit: You seem to have the same problem with video :(
