How to detect if streaming is blocked
I am using the enterprise version of JWPlayer. Some visitors to my site (but not all) cannot stream videos; the embedded videos simply don't show up on the page for them.
I suspect this is because streaming videos are blocked on their company networks, but I don't know for sure. (This is just a wild guess on my part.) Is there a way (some tool or webpage) I can send people to so they can test to see if, indeed, blocking is occurring?
