RE: Camera stream

The optimal solution for streaming video is to acquire another Raspberry Pi 2W (or a higher version) along with its camera. Install all the necessary components on this additional Raspberry Pi, while keeping the existing 2W on the Prusa board to continue its 10-second routine (as a backup).

The total cost of this solution is likely to be less than a filament spool.

RE:

I guess most people are not aware that changing from image capture to video stream would make Prusa actually a video streaming company, and that is really not as easy as it sounds (imagine Prusa becoming Twitch or Youtube Live ;D ):
- I believe lot of people are watching on the screens only from time to time (unless someone uses additional tools to scrape pictures to make a video from it, but I guess there are much better options that can be run locally or in the same network)
- real streaming is much more problematic than just sending an image, thankfully over the years there are some updates to it (but I would really drop RTMP and HLS in favour of MPEG-DASH)
- what could be done is to process locally video into a chunks and upload them as simple files as mpeg-dash does it (but with single stream and simple compression due to computing constraints, still that would probably end in 15MB blocks and that's quite a lot looking at current camera image uploads, and still it would take some noticeable delay vs what is actually happening)
- most people send single camera but if you get more cameras and printers into the mix then you really can easily hit your upload stream limits
- all in all it significantly increases transfers and backend processing to merge fragments into a later downloadable content such as single video file

All this increases overall costs, so I believe that would rather become paid version, if ever.
If you require realtime streaming then PrusaConnect is rather not way to go, you want to have it as close to local network as possible.

See my GitHub and printables.com for some 3d stuff that you may like.
