Does anyone have the actual technical specs for the 8MP 4K-N camera? Like resolution, FPS, output encoding? I’m looking to optimize the settings for ustreamer on a RPi Zero 2 W and I’m kind of wandering in the dark as I’m no Linux nor video expert. TIA!!!
Answering myself, you can disregard this post. I’m using ustreamer and it appears to only support up to 1920x1080, so other, higher resolutions appear to be irrelevant. The camera can output this at 30fps.
Hi Steve,
I have yet to try uStreamer with the latest LB 2.1, but our camera developer reported good results with it!
He posted the command used to “share the first USB camera at its native resolution on port 80”
ustreamer --device=/dev/video1 --host=0.0.0.0 --port=80 --format mpeg --resolution 2562x1944
You can see the available cameras and their resolutions with these commands:
v4l2-ctl --list-devices
v4l2-ctl -d /dev/video1 --list-formats-ext
I’m not sure that’s entirely true. What’s the output of the v4l2-ctl commands mentioned above?
I got ustreamer to work with 2562x1944. If I try the full native resolution of the camera, ustreamer hangs. Overall, it works pretty well. However, after it being up for an extended period of time, the entire Rpi stops responding. It may be getting too warm, even though I installed the supplied heatsink. Maybe it’s just you streamer that hangs, because I can SSH back into the Rpi and restart ustreamer. I greatly appreciate the inclusion of wireless USB cameras into the release candidate!
Interesting! Thanks for the feedback.
If the problem really is the Pi overheating, lowering the FPS might help.
uStreamer defaults to “maximum possible”
On that Man page, there are a ton of other options that seem relevant/important. For example --log-level 3 to get debug messages.
Yeah, at that resolution (2562x1944) it goes to 15fps. I may try the debug log item to see what I can see. I’m not a Linux guy, so I kind of have to hack my way through things - like where that log might end up. 
Regardless, please extend my thanks to the developers for including HTTP streaming camera support. My 90w CO2 laser is now fully wireless, so no tripping on USB cables!
