Need help installing ustreamer

@bearer said in Need help installing ustre sure the camera is plugged in.
eamer: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:)
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 -
@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
[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.targetare 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.

@luckyflyer Are you sure the
ustreamer@.servicefile is located in/etc/systemd/systemand that it's named exactly that?Try
ls -al /etc/systemd/systemthencat /etc/systemd/system/ustreamer@.service -

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)
-
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? -
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 -

I noticed that inls -al /etc/systemd/systemthat in line 29 it is
ustreamer@.service:With a colon, instead of
ustreamer@.serviceIs this a problem?

They say great minds think alike................ maybe, I don't know lol.

well, you can use cat and heredoc to create files like so
cat << EOF > /tmp/yourfilehere These contents will be written to the file. This line is indented. EOFbut redirects and sudo gets messy so you'd need something like
cat << EOF | sudo tee /tmp/yourfilehere These contents will be written to the file. This line is indented. EOFbut you'll have to deal with escaping on the command line etc. i to use it from time to time, but its not always the best option.
