Hi!

I have a question. My wowza server is runngin on Azure cloud.

When i try to do playback(with Seek bar), i always set “nDVR parameter” the end of URL.

On the other hands, all documentation of wowza say that i should set “DVR parameter”.

But when i set the DVR parameter, it is not work(displaying endless seaching stream).

What is nDVR parameter? And is it the kind a issue?

You do not need to have it say nDVR on the end of the url. Just DVR. I will send some docs with examples for you @Naoaki Nomoto.
