Oct 31, 2026, 11:34 AMDuck duck fedi, please help me avoid the mix of old information and slop
I have a USB camera
I have a headless Debian Linux computer
I want to quickly and temporarily watch the camera over the network on my phone and/or laptop
Running a command in tmux is fine for this situation, I don't need a full fat surveillance system
How do?

this might be helpful?
@M0YNG Here are some ffmpeg commands from my DVB-S2X days, perhaps you'll find them useful:
Transmit side:
ffmpeg -s 640x480 -f video4linux2 -i /dev/video0 -f pulse -i default -vcodec libx265 -slices 4 -thread_type +slice+frame -x265-params "keyint=10:repeat-headers=1" -preset ultrafast -tune zerolatency -bufsize:v 1k -b:v 700k -maxrate:v 700k -r 20 -f s16le -ar 48000 -ac 1 -acodec libopus -async 1 -bufsize:a 1k -b:a 10k -f mpegts -muxrate 889000.0 udp://127.0.0.1:48550
@M0YNG Receive side:
