m36606 Web Interactivity Track

Thank you. We have some minor concerns that we need to handle ‘sparse’ events. We suspect much of this is possible already using metadata cues in HTML, the existing metadata text track support in the ISO BMFF (part 30), labeling of the track with the right ‘kind’ (i.e. signaling it needs to be dispatched into the javascript), and so on. We need to “connect the dots”, probably in an update to part 30 to clarify all this.

7. m36367 Does a trailing movie fragment help?

Thank you. We note that the segment index might need to have a different definition of SAP?

8. m36368 Long samples and fragmented ISO BMFF files

We think we used the sample_has_redundancy field in at least one specification to cover this (maybe part 30)? Indeed we did.

9. m36667 Comments on semantics of track reference box in 14496-12

We clearly have some cleanup to do; into the defect report!
