Hello,

I have recently enabled the ndvr addon and althoug it is already configured and I can test it inside wowza streaming engine with the test players, I will want to integrate a HDS reproductor into my site and I think that I can do it with [http://www.osmf.org/](http://www.osmf.org/) the problem is that I am doing something wrong in the flash media playback setup and when I click preview it tells me the following:

The F4M document contains errors

URL missing from media tag.

Could anyone tell me what is the problem, and how to solve it?

Thanks

You can use [onHTTPSessionCreate](https://www.wowza.com/docs/how-to-control-access-to-http-streams-cupertinostreaming-sanjosestreaming-smoothstreaming-mpegdashstreaming%28cupertinostreaming-smoothstreaming-sanjosestreaming-mpegdashstreaming%29) to look at ip address, referrer, etc, and reject connections that you don’t want

I think the ModuleHotlinkDenial module does not work with HDS connections, how can I manage that problem?
