Description
A couple more edge cases have come up where usng rvfc or raf for more accurate cue changes isn't working., with audio in video els (there's already handling for audio in audio) and background tabs.
Specific Changes proposed
Use the
timeupdate
event as well as the rvfc and raf callbacks to check cues. This is a bit overkill for "usual" playback but avoids edge cases. If the more preceise callback trigger first the cue will update but the timeupdate event should catch any that were missed, notwithstanding thattimeupdate
was always somewhat unpredictable.Should fix #7910 (audio in video els and Samsung being weird) and #7902 (no updates off screen).
Requirements Checklist
