Can I use video subtitle tracks to synchronize an entity?

Hi Alexander,

I realise that my response is very late, but thought might be interested to know there is now a proposal which addresses the first issue on your wishlist:

  1. ‘Html 5 Video Track’ in synchronization (if possible) with cesium

WebVMT is a metadata-focussed variant of WebVTT which can synchronise moving ‘entity’ paths with video using the HTML element in a web browser, including interpolation for frame accuracy.

Please add a comment to this issue to briefly outline your use case and help us ensure that the proposed solution addresses your requirements.

Many thanks for your support.

Rob
