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:
- ‘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 .
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
