How can I download an entire Twitch stream in mp4 format?

I recently saw a good Twitch stream and would like to download it (complete and in mp4). Does anyone have a way how to do that. Would be helpful thanks.

You go to your Twich dashboard (https://dashboard.twitch.tv) then to content and then to video producer. There you can download the stream, but only if you have activated the recording in the settings beforehand
