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