There isn't a PIPS stream on test, so we need to use the live endpoint in order to see it working when not on live. Harvey has looked into whether we can curate a test PIPS stream to use, but it doesn't seem possible https://bbc-tpg.slack.com/archives/C03RMKNL7GC/p1772618041978389

This is a workaround so that we can see the stream on test and preview.

Is this something we're removing once its been tested on Preview?

[emilysaffron]

We could do? I was thinking it might be helpful to leave in place for ease of testing in future, but maybe we could leave a comment somewhere nearby instead to indicate that it needs to be edited when locally developing.

Is there a downside to leaving it in?

[amoore108]

It just means that Hindi Live TV pages will always use the Live mediator.host and the more languages we add will do the same?

I'm not across the Dazzler stuff, so maybe its needed, but typically its best to keep environments isolated, rather than mixing Test/Live endpoints as it can lead to unexpected behaviour.
