Hi,
Currently there is no option to rotate a video within Wowza Streaming Engine.
I did a quick search and found the following post in the WordPress forum which resolves the same issue using Handbrake.
I will add this as a feature request to our backlog on your behalf. Features which are added to our backlog are reviewed and considered for future versions of Wowza Streaming Engine.
At this time I can’t confirm if the feature will be approved and if so, any time-scales for it’s availability.
Thanks for the feedback.
Regards,
Jason
