With #337 we'll have a way to stream a rendered video to twitch or locally. Unfortunately it isn't really live, as the video needs to be rendered beforehand.

Describe the solution you'd like
I'm wondering whether it's feasible to stream single images instead to have an actual live view which can be like 5fps but at least it's live. That way we could figure out the current position of the live stream and could update some changes live without restarting the animation.
In the future I would love to stream events like presidential elections live on a map. It would take new data from a source every couple of minutes and then starts an animation with it.

Additional context
This can be similar to something like this then: https://www.twitch.tv/dutchsinseofficial
