You'll post a link when the day comes, I assume. Are you streaming directly from PS4 using the built-in features?
Of course. Yep it's pretty simple to do. It's not great as it makes your screen smaller and puts a bar by the side with the chat window up, but I can live with that. I have fibre broadband so speeds should be fine.
Funnily enough I did a little test the other day and fired it up whilst I was starting a game on FIFA. Must have been 30 seconds, just the loading screens. I got two comments from YouTube channels saying "HEY GREAT STREAM GUY WE LOVE YOUR WORK"
