why force the protocol? we assume that a working path is given and nobody promises that SERVICE_PATH is required.
Config should allow getting a fully functional URL as the service url can be proxied by another service fr example in an onPrem env.
The default protocol can be left // so we get the one the page has

@OrenMe it's our Kava analytics you can't set there URL for another analytics service.
for example, the value we get from the server doesn't have the SERVICE_PATH, so it won't work without that if I understand it correctly.

the plugin config should be explicit - it refers to a url, not partial.
I would want us to leave it like that so if issue arrises it will be as easy as setting a new URL.
This means - leave default as is, and pass the correct url in kaltura player - add the service path there.
If someone needs to set another url, let's say testing purposes or setting a local proxy he will be able to set his own url.
