Hello Holger,
At this time we will not be utilizing any option outside of Officially available encoding options to Instagram TV with Wowza ClearCaster.
Our focus is broadcast success and the option shown in this video could be blocked at any time since this is not an official offering.
Please do keep watch on the following page:
https://www.wowza.com/docs/wowza-clearcaster-release-notes
for any future updates that may integrate an option to broadcast to Instagram TV
If this feature does become available it will also be discussed in any future webinars:
https://www.wowza.com/company/events
I will also work to return to this thread if the situation around this option/feature changes.
Regards,
Jason Hatchett
Technical Support Supervisor – Wowza Media Systems
