Steps to reproduce
Test case :
- encode a video with burned in subtitles
- create a video player using this video and the webvtt subtitles as a track
- when the video is played, a random delay from around 10 ms to several hundreds ms is observed on cue change events and on the video.
Demo : http://naouak.github.io/WebVTT_sync_test/ED.html (calculated delay is in console output)
Subtitles should be synchronized to the corresponding frame of the video. More than 2 frames of delay is not really good as it could lead to some issues with scene changes.
