Bug 201216 – Setting currentTime doesn't work on loadedmetadata event

• Status: NEW
• Component: Media

[Damjan]

I want to implement functionality to play video from some time. 
Sometimes it's working, sometimes not.

Browser: Safari 12.1.2 (14607.3.9)
OS: macOS Mojave 10.14.6 (18G95)
Video stream protocol: HLS
Web player: Safari native player

I implement that in a way that set HTMLMediaElement.currentTime when loadedmetadata event is triggered.

Expected:
Play video from setted currentTime.

Actual:
Sometimes video plays from beginning, sometimes video plays from setted time.

Example could be found on link:
https://codepen.io/index23-the-decoder/pen/ExYmGyd

This example always works fine on other web players like video.js.

At the point where loadedmetadata is fired, we have an AVAsset but no AVPlayer or AVPlayerItem yet. I wonder if we're not correctly saving off the seek in order to apply it to the AVPlayerItem once it's created.

Are there any new information about this issue?
