Error #1083: The prefix "x" for element "xmptk" is not bound.

Hi, I have done a preliminary round of integrating into our OSMF player. So far I see one error that's come up 2 times:

TypeError: Error #1083: The prefix "x" for element "xmptk" is not bound.

I assume it has to do with malformed or non-existent XML, but why is the error being triggered and is there any way to prevent it?

Thanks.

Can you provide your manifest file?

Probably an error occurred because your manifest XML file contains additional namespace. Root cause is that player rewrites XML file to use an unified namespace (please go to removeNamespacesAndBuildXml method for more information). In the past we had issues with different format of urn:mpeg:dash:schema:mpd:2011 namespace. This is workaround. Probably we can do this better.
