Need help installing ustreamer

luckyflyer

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.target

Then rebooted, but no image on pc which is http://192.168.0.181:8080 or on Duet pi
http://0.0.0.0:8080

I 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.

@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.

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.

luckyflyer

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.

luckyflyer

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?

A Former User

not so sure about the 2 minutes, systemd isn't my forte.

nor am I 100% sure about the usecase and proposed solution is the best match.

but yeah, the command to edit the files as root is fine, it does the same as sudo nano /etc/.... just without loopholes and it respects the EDITOR env variable for those who have customized their profile.

are you looking for a solution that will autostart when the camera is connected, or a solution that will autostart when the pi starts (with the camera always connected)?

my day is coming to an end, but i think the last bit there might clear up some misconceptions?

luckyflyer

I normally will keep the camera always connected so the autostart with camera connected would work for me. But either would work ok.

A Former User

(the template thing might do both, idk, if I fidn a camera tomorrow i'll play with it a little in the evening)

luckyflyer

Sounds good thanks.

luckyflyer

I notice that line 2 uses a upper case I and line 5 uses a lower case i Don't know if this is anything or not, thought I would mention it.

thats intentional. %I gets escaped so it doesn't contain special characters, which is needed for the name (and i suspect gtj0 would have corrected it if I was mistaken:)

@bearer said in Need help installing ustre sure the camera is plugged in.

Correct. It's just in the description anyway.

@luckyflyer start simple...

### Move the rules file out of the way
$ sudo mv /etc/udev/rules.d/80-ustreamer.rules /root/
### Reload systemd
$ sudo systemctl daemon-reload
### Enable ustreamer@video0 to start on boot.
$ sudo systemctl enable ustreamer@video0
Created symlink /etc/systemd/system/multi-user.target.wants/ustreamer@video0.service → /etc/systemd/system/ustreamer@.service.
### Make sure the camera is plugged in.
### Reboot.
$ sudo systemctl reboot
###  When the Pi is back up, check the status of the service...
$ sudo systemctl status ustreamer@video0

luckyflyer

@gtj0 Thanks for your help and sorry to be such a pain.
I enter each command and this is what I get.

pi@duet3:~ $ sudo mv /etc/udev/rules.d/80-ustreamer.rules /root/
pi@duet3:~ $ sudo systemctl daemon-reload
pi@duet3:~ $ sudo systemctl enable ustreamer@video0
Failed to enable unit: Unit file ustreamer@video0.service does not exist.

I have followed the previous steps exactly and several times using copy and paste. I'm using nano3.2 and do ctrl X Yes then enter to save and then reboot. I do this for both of the files. I'm at a loss to for why the service does not exist.

One thing I've noticed is when I go back into the editor the text that I previously entered

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"

and

WantedBy=multi-user.target

are still there, is this normal? I have the feeling that the files are not being saved. I'm wondering if I don't have permissions set correctly but get no error stating that I don't. Doing research to understand about permissions.

gtj0

@luckyflyer Are you sure the ustreamer@.service file is located in /etc/systemd/system and that it's named exactly that?

Try ls -al /etc/systemd/system then cat /etc/systemd/system/ustreamer@.service

Looks like the first one is there, but not the second.
I think it's something with my editor but don't know how to check to see.

@luckyflyer maybe try making it executable?

sudo chmod +x /etc/systemd/system/ustreamer@.service

(long shot)

luckyflyer

tried it,

pi@duet3:~ $ sudo chmod +x /etc/systemd/system/ustreamer@.service
chmod: cannot access '/etc/systemd/system/ustreamer@.service': No such file or directory

@gtj0 @bearer
Been reading up on the cat command, was wondering if that would be a good way to create and save the missing file?

A Former User

hmm, does the filename have a : at the end?

sudo mv /etc/systemd/system/ustreamer@.service: /etc/systemd/system/ustreamer@.service
sudo chmod +x /etc/systemd/system/ustreamer@.service
