For me, my high bar that I have yet to beat, was the time I pivoted the running OS (ubuntu) into RAM over SSH so I could unmount and image the boot drive without rebooting and loading a live USB (Which would have required a ticket with my provider to enable IPMI)

Piped the ps2 usb camera /dev/video0 to nc. Reverse port fwd'd to my router 200 miles away, and got vlc 200 miles to connect to that port and it worked. No rtsp or server required

    And now we have a new streaming service 🤔 Really nice.

    I was thinking that by now, we should have enough bandwidth to stream webcams straight to each other without HLS or WebRTP or whatever. Just make the device available over a port or, as you did, cat it to another PC and voilà. Actually, why don't we stream raw camera feeds?

    Most devices will give you the latest frame on a read essentially. VLC accepts a tcp:// address and interpreted it correctly somehow. The raw bandwidth on the potato 320x240 or whatever was peanuts, but even if you didn't get all the frames per second the device will discard old frames and you got the latest frame anyway. So pretty cool indeed. Doesn't really multicast though. For that I suppose you could netcat to local multicast address and then connected to that same address, but I've never tried it. VLC may not receive the headers that a read may open with would be my suspicion
