Some businesses want to control their streaming process on per-user and per-stream level in addition to general protection methods like
limitation. This is required especially for
systems where viewers pay for accessing the media.
provide a framework which allows collecting detailed data for all connection and making decision to allow or deny each connecting user. This may be used for
logic, calculating each
user simultaneous connections,
and much more.
These are the steps for a customer to integrate those capabilities into customer's workflow:
Nimble sends requests to customer's handler. This handler must be accessible via HTTP/HTTPS and it must be able to accept POST requests. Those requests may be formed via either
JSON or XML,
this can be set up in WMSPanel settings.
Handler needs to do a few things:
Please check a
basic handler example
for PHP. It just takes incoming request, logs it and returns a couple of IDs to be blocked. You should take a look at full
JSON request example
handler response sample
Now we need to set up a link between Nimble Streamer instances and the handler. Select
Control / API setup
menu and select
Push API tab
which is the one we are going to use now.
Define the following:
In order for Nimble to start sending requests, some changes must be made on your web server side. Media URL needs to be modified to include special
that would contain required information.
For example, you have this URL for your live stream:
The modified URL would be:
To generate signature you need to modify your front-end source to include code snippet.

You can find all samples in
WMSPanel github repository
and adapt them for your use case.
Two important things must be specified here:
To define restriction settings on server side,
must be notified about it. The set up is made via WMSAuth paywall setup.
In WMSAuth, every restriction may be applied to a group of servers. So the first thing to do is to create a group and assign one or more Nimble servers to it. Check this screenshot for details.
Within a group, there may be several rules, each working with its
set of streams.
Just click on "Add rule" to enter rule creation page.
See how you can specify Nimble
regular expression on the screenshot below.
Now you need to specify
a key, or password,
which was inserted into the media signature on web server side in section "Make PPV signature" above.
After you save the rule, it will be applied to the server within a few seconds.
The debugging handler and interface
allows receiving data from servers and viewing results via your browser. Use it to see what requests will come from your server instances to your own handler.
Now when the chain is set up you will be receiving updates on current streaming status. As response you can send back the blocked IDs list and so control your streaming workflow.
This functionality also works fine with
geo-location and IP ranges restriction
The Paranoid’s Guide to Internet Video Streaming
by Thomas Gires is very useful to see real-life example of using
pay-per-view feature set for
via light-weight edge.
Nimble Streamer will send requests and receive responses for pay-per-view framework regardless of WMSPanel availability. If your server can't connect to WMSPanel for some reason, this functionality will still work perfectly. Once the handler settings are set up, the control panel is not used anymore.
