Accessing V4L cameras on *other* devices!!

Post by Kamoshiyaan » Thu Jan 03, 2019 3:33 pm

What kind of sorcery must I endure?

I have a few systems on my network. 1- with a geovision 4-port encoder card, and 2- raspberry pi with a USB webcam. Both devices have a /dev/video0 node supported by v4l.

I'd like to connect to these cameras from my main zoneminder box. Is there some way to make those cameras network-accessible without installing zoneminder on those, also?

there is a way to stream the cameras that would be accessible over the LAN using FFSERVER. I have used this method successfully with ZM but I have not done this in a while so I am rusty. Here is a link that has info to get you started.

But I found out ffserver is depreciated and is replace by this promising program

I was experimenting with v4l2rtspserver on SBC:s and USB cams. My goal was to stream 3 Logitech C930e from RAW max resolution through v4l2tools.

This worked well at moderate resolutions but I had some problems at highest settings. Unfortunately my cams were fried by lightning so I never finished the setup. Also my MB got toasted. Might want to avoid USB stuff on top of roofs :)
