Hello all, Thanks to everyone who provided feedback on the github issue.
We have now released a new draft of the qlog main schema detailing the new streaming format [1]. qvis [2] has also been updated to support the new approach, so you can load files using the new format/extension. If you encounter any issues, please let me know. I will be available during the hackathon next week for people who want to implement this new setup and have questions/find bugs/etc. I am also open to discuss qlog/qvis support for other emerging use cases, such as multipath, masque, webtransport, etc. if people are interested.
