描述

Actual behaviour

Video doesn't play. After clicking the play button, the progressbar shows the buffering animation, the poster image disappears but the video never starts.

Environment

  • Plyr: 3.3.21
  • Browser: Safari for iOS
  • Operating System: iOS
  • Version: 10.3

Steps to reproduce

I can reproduce this also with the example on https://plyr.io. Not every time but at least one out of 10 times. If the video plays, just hit reload and try again and eventually it won't play.

研究方向
Investigate the video playback failure on iOS < 11 by examining Plyr's event handling and the HTML5 video element's behavior. Reproduce the issue in an iOS simulator or device, focusing on the play button click sequence and buffering state. Look for any race conditions or missing event listeners that could cause the video to stall after poster removal.
