Hi guys,

How can add the cors header on the mpeg dash streams. I know how to do it for smoothstreaming and hls:

cupertinoUserHTTPHeaders

Access-Control-Allow-Origin: \*

smoothUserHTTPHeaders

Access-Control-Allow-Origin: \*

What is the parameter for mpeg dash?

dashUserHTTPHeaders?

Regards,

Ferdinand

Hi,

For other users, you would need a minimum of [Wowza version 3.6.2](https://www.wowza.com/docs/wowza-media-server-3-6-2-release-notes) in order to use this property. If you continue to have issues, do send us a zip copy of your conf/ and logs/ folders for further review.
