BlobURL src video not playing on iOS 10.3

Preload the video as Blob

and then use createObjectURL()

to create BlobURL. Video playback on all OS / browsers, but on iOS 10.3 was rejected when trying to play (promise) with the message:

NotSupportedError (DOM Exception 9): The operation is not supported.

If you switch the <video>

src to a regular video, it plays normally.

Code to get blob url:

fetch(videoURL)
  .then(response => response.blob())
  .then(window.URL.createObjectURL)
  .then(console.log)
