# What to do if WebRTC on iOS shows a black box

> Fix WebRTC video showing a black box on iOS Safari by adding the playsinline attribute to your video tags, which is written playsInline in JSX.

I was doing a project using WebRTC and in particular with the PeerJS library.

It worked fine on desktop but on iOS Safari, all I was seeing for the video streams was a black box.

Even for the local stream.

What I had to do was to add the `playsinline` attribute to the `video` tags for both the local and remote streams:

```
<video id="local" autoplay playsinline muted></video>
<video id="remote" autoplay playsinline></video>
```

(note: it's `playsInline` in JSX)
