iOS video issues are not new (see: #6443, #6152) but usually come down to carefully following the Autoplay guide for media and Web Audio APIs docs.
While working through the release tests, we noticed that video sources have an internal video element which opts for fullscreen in iOS (with possible dependence on iOS version and iPad vs. iPhone) 😱 . I personally observed the issue in iOS 15 on an iPhone 7 but not on an iPad with iOS 12.5.4.
The issue can be seen on this page: https://docs.mapbox.com/mapbox-gl-js/example/video-on-a-map/
Before this fix, video sources require user input to play and then take over the whole screen:
before.mp4
Adding
video.playsinline = ''(see: playsinline docs), the video now autoplays as expected:after.mp4
This fix results in correct behavior (autoplay; no fullscreen) on both devices I have access to:
iPhone 7 with iOS 15
iPad Mini with iOS 12.5.4
