描述

Expected behaviour

Setting player.currentTime after the ready event sets the time at the appropriate position (an arbitrary point in the video).

Actual behaviour

Only on iOS, the video plays from the start instead of the specified position.

Environment

  • Browser: Mobile Safari
  • Version: 11
  • Operating System: iOS
  • Version: 11.2

Steps to reproduce

  • Initialize Plyr on a video element
  • Set up an event listener for the ready event
  • Set player.currentTime to a new time after the ready event has fired

I found a workaround by listening for the playing event, setting player.currentTime, and then removing the event listener. However I'm not sure if this behavior is expected on iOS, or if it's even possible to accomplish.

PS. thanks for the great player, it's a breeze to work with and the new version looks amazing!

研究方向
Investigate the timing of the 'ready' event in Plyr on iOS Safari 11. Compare with the expected behavior on desktop browsers. Check the HTMLMediaElement.currentTime specification and any known issues with setting currentTime before the 'playing' event on iOS. Look at the Plyr source code (especially src/js/plyr.js) to understand how the ready event is emitted and whether there is any workaround needed for iOS. Testing on an actual iOS device or simulator is required to confirm the bug and evaluate the workaround provided.
