Need help installing ustreamer

sudo systemctl start ustreamer@.servicethis seems to be a so called template service, so it needs the name in the invocation;
sudo systemctl start ustreamer@video0.servicewhich probably means
Description=UStreamer for video0should be changed toDescription=UStreamer for %Ibut doesn't affect the issue at hand I believe. -
@luckyflyer Yeah sorry about that. I should have given more compete instructions. @bearer is correct about being a template service and has the correct command line to manually start and stop the service.
I don't see (or don't remember) whether the camera you're using is a USB cam or a MIPI cam directly attached to the Pi's camera connector. If it's a USB camera, then here are updated service and rules files that will automatically stop the service when the device disconnects..
/etc/udev/rules.d/80-ustreamer.rules:
ACTION=="add", KERNEL=="video0", SUBSYSTEM=="video4linux", TAG+="systemd", ENV{SYSTEMD_WANTS}+="ustreamer@%k.service" ACTION=="remove", KERNEL=="video0", SUBSYSTEM=="video4linux", RUN+="/bin/systemctl --no-block stop ustreamer@%k.service"/etc/systemd/system/ustreamer@.service:
[Unit] Description=UStreamer for %I [Service] Type=simple ExecStart=/usr/local/bin/ustreamer --exit-on-parent-death -r 640x480 --static /tmp/ -d /dev/%i --host=0.0.0.0 --port=8080 [Install] WantedBy=multi-user.targetAs a reminder... "0.0.0.0" is a special IP address that tells server software to listen for connections on all ip addresses on the system. It can never be used to actually connect to anything.

@gtj0,
Yes usb cam, I will try this in about an hour. Thanks to you and @bearer . -
@gtj0 thanks for sharing this, gonna have to try with with my auto--bossac-recovery plan.
re: 0.0.0.0 that had me questioning a few things (in the sense OP said he could connect to it)

What mipi camera do you guys recommend for print monitoring? I've been looking at the arducam v2 https://www.amazon.com/Arducam-Raspberry-Official-Megapixel-Acrylic/dp/B083FNFPF2/ref=sr_1_3?dchild=1&keywords=arducam+v2&qid=1590854384&sr=8-3
Or is there something better out there.

Have you seen this one High Res PI Camera with interchangeable lens

@Dougal1957
Nice looking cam , I would like to buy from a US vendor if possible, is it available here anywhere? -
The downside of RPi cameras is the distance limit and the flat ribbon cable. You get a lot more choices if you use a USB camera.
I use this one
https://www.amazon.com/gp/product/B07HVT2XZL/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
because it has LED illumination, is easy to mount, move, and use for other things if needed. -
@luckyflyer You can get RPi cameras with interchangeable lenses on Amazon. Here's one...

and 2 meter long cables are available for cheap as well https://shop.pimoroni.com/products/raspberry-pi-camera-cable?variant=10312200583 don't know what effect they would have mind
-
@gtj0 But don't the mipi cams offer greater programmability and flexibility than usb cams?
A picture of the back of my printer, a 30 cm cable would be perfect, up to the top and out.!
-
@luckyflyer I don't really know as I don't have one yet but am considering one with possible a wide angle lens on it not a cheap combination mind

Sup. The ustreamer developer here. I am glad that you use my software, but just in case I want to warn those who want to use RPi CSI cameras: it doesn't work with ustreamer. The reason is that these cameras use their own specific non-v4l2 driver. It is possible to configure them as v4l2, but this requires research and I have not yet addressed this issue. So if you don't want any problems, use regular USB cameras.
Quick answers to old questions:
0.0.0.0is a special address that means "listen all ipv4 interfaces". If you choose this option, you can connect to the streamer via the ip address of your network card orlocalhost(127.0.0.1).- You can't listen to port
80unless you are root or have theCAP_NET_BIND_SERVICEcapability (blah-blah-blah the network magic). If you want to run ustreamer via systemd on port 80 under non-root user, you need to add a parameterAmbientCapabilities=CAP_NET_BIND_SERVICEto the Service section - Use the HW encoder: almost all cameras support it.
- If you're afraid that someone will see your video, use password authorization. It's better than nothing.
PS: I was just passing by, so if you need any help, go to discord, the link is in the ustreamer repository on github.

@mdevaev Thank you very much for that info just saved me a ton of cash

Wow, good to know.

Still having trouble getting ustreamer to auto start as a service. I have entered @gtj0 revised entries which are,
sudoedit /etc/udev/rules.d/80-ustreamer.rules:
ACTION=="add", KERNEL=="video0", SUBSYSTEM=="video4linux", TAG+="systemd", ENV{SYSTEMD_WANTS}+="ustreamer@%k.service" ACTION=="remove", KERNEL=="video0", SUBSYSTEM=="video4linux", RUN+="/bin/systemctl --no-block stop ustreamer@%k.service"sudoedit /etc/systemd/system/ustreamer@.service:
[Unit] Description=UStreamer for %I [Service] Type=simple ExecStart=/usr/local/bin/ustreamer --exit-on-parent-death -r 640x480 --static /tmp/ -d /dev/%i --host=0.0.0.0 --port=8080 [Install] WantedBy=multi-user.targetThen rebooted, but no image on pc which is http://192.168.0.181:8080 or on Duet pi
http://0.0.0.0:8080I then tried to manually start the service with,
sudo systemctl start ustreamer@video0.service
and get,
pi@duet3:~ $ sudo systemctl start ustreamer@video0.service Failed to start ustreamer@video0.service: Unit ustreamer@video0.service not found. pi@duet3:~ $@bearer mentioned this,
*) edit: this assumes the default EDITOR environment variable is set to nano, but if you've changed it you probably know how to use the editor:)
I wondered about this but Raspbian buster comes with nano as the default editor and since I haven't changed editors this shouldn't be an issue. -

I wondered about this but Raspbian buster comes with nano as the default editor and since I haven't changed editors this shouldn't be an issue.only relevant when using
sudoedit(probably other times as well, but in this context, only for sudoedit) and the instructions for getting out of nano wouldn't work for other editors - but then again, if someone have changed the default I'd wager they know how to use it. -
Hmm, that is what I'm using,
sudoedit /etc/udev/rules.d/80-ustreamer.rules:
sudoedit /etc/systemd/system/ustreamer@.service:
should I use something else? -

oh dear; that is the one question you do not ask the internett and live to talk about..
jokes aside, no and yes. occasional editing of small files on debian and derivatives nano is fine. but nano isn't always available when you wander outside the comfort zone, and there are fanatics who will tell you that you won't get into (insert happy after life place) if you use anything but their favourite editor etc.

Lol can I buy you a plane ticket to the desert southwest, my guess is you you would have this sorted in about 2 minutes.
So
sudoedit /etc/udev/rules.d/80-ustreamer.rules:
sudoedit /etc/systemd/system/ustreamer@.service:
should work ok for me?
