Hello, Mihai Popescu writes: > For camera access as an user see: /etc/fbtab (fBtab not fStab) Is fbtab usable also in the case of login via xenodm? Into fbtab one should enter the login device name (like /dev/ttyp1), but is there such a thing when xlogin logs you in? Thanks Ruda

Thank you for any comments. Ruda Hi Ruda, You can configure FFmpeg to dump an HLS stream into a location served by httpd. FFmpeg does support some USB cameras using the V4L2 protocol, but you may need to play around with formats and resolutions to get the optimal experience/performance. I've done this extensively, as I'm currently working on a CCTV project that will run natively on OpenBSD. Regards, Jordan
Re: video capture / streaming
For camera access as an user see: /etc/fbtab (fBtab not fStab) For easy streaming see: vlc from ports. Be sure to use archive search next time.

I did something like this ~2 years ago, so maybe I'm wrong, but the permission get resetted on reboot, so you should edit /etc/rc.local. I can't comment on the rest.

video capture / streaming
Dear list, I'd like to stream video from my (usb-connected) camera via a web server. The 1st I tried was to see if the camera works. So: odin$ video video: /dev/video: Permission denied odin$ doas video No protocol specified video: cannot open display :0.0 odin$ xhost + access control disabled, clients can connect from any host odin$ doas video ^Codin$ Ie, at last I saw an X window with the video. But is it possible to run the video command as an ordinary user? (I had to doas...) Next I want to stream the video via some kind of a server. On the internet I saw people using 'ffmpeg' to serve the file somehow, as well as using 'nginx' with the 'rtmp' module. Is any of this the way how you would achieve the goal, or is it possible to use, say, the 'httpd' server? At this moment I know very little both about streaming and available servers to do the job, and that's why I am asking for recommendation based on some experience and knowledge.
