All the pictures you linked are very much related to software development, your post targets economics exclusively, it has absolutely nothing to do with cryptocurrencies as a technology.

Note

This driver is a joke.

If you want another “unga-bunga” approach, you can use netcat:
On the player machine:

nc -l 1234 | mpv -

On the sender machine:

ffmpeg | nc 192.168.1.4 1234

Of course, you can use any unused port instead of 1234.
