Need help installing ustreamer

luckyflyer

Ok I'll read that again

@luckyflyer maybe post what ustreamer says when you start it, and run

@bearer said in Need help installing ustreamer:

sudo netstat -lt4np more usefull for future ref.

instead of pgrep?

luckyflyer

Here ya go.

huh, they're contradicting each other unless I'm off my rocks. odd; will see how it behaves here in a bit

luckyflyer

Well now its refusing to connect @ http://0.0.0.0:8080 on pi's chrome but it did until I stopped ustreamer and then restarted it.

luckyflyer

So I rebooted pi and now can access ustreamer again on pi chrome http://0.0.0.0:8080

luckyflyer

I'm now seeing this, it's the last entry in ustreamer's start up, haven't seen it before.

luckyflyer

So this is what I'm getting now,

@luckyflyer said in Need help installing ustreamer:

So this is what I'm getting now,

that looks normal, should be able to connect from your pc to whatever IP address the pi has. confirm the IP addressess of the Pi with hostname -I

luckyflyer

Success, I can get into ustreamer from my pc on pi's ip addr.
@bearer, I want to say a big thank you for your help, wouldn't have been able to get there if you hadn't stepped in!!

@gtj0 Also thanks!

gtj0

@luckyflyer As a reward are you going put on a show for us???

luckyflyer

I can sure do that but........ murphy has made another appearance.

I have the standalone pi working good so now its time to load ustreamer onto the Duet pi.
The first thing I do is assign a static ip for eth0 and wlan on Duet pi, thats done new address's work.
Next I run.

sudo apt-get install libevent-dev libjpeg8-dev uuid-dev libbsd-dev

I get an error saying cannot reach raspbianraspberrypi.org I try several times thinking that maybe the server is down. I then try one of my pi's that is dhcp and it gets on the server immediately. I don't understand this do a google for this type of problem and come up with nothing. So I disable firewall still no. I then remove the static addresses and Duet pi is now able to reach the server.
So the above command now downloads I proceed with the install/compile with these notes I've made,

**Check if make and gcc are already installed, if not installed install with sudo apt-get install

Get these,
sudo apt-get install libevent-dev libjpeg8-dev uuid-dev libbsd-dev

Now compile ustreamer

$ sudo git clone --depth=1 https://github.com/pikvm/ustreamer
$ mkdir ustreamer
$ cd ustreamer
$ make

check if working with
$ ./ustreamer --help**

When I get to make I get this error,

pi@duet3:~/ustreamer $ make
-- CC src/device.c
mkdir: cannot create directory ‘build’: Permission denied
Assembler messages:
Fatal error: can't create build/src/device.o: No such file or directory
make: *** [Makefile:92: build/src/device.o] Error 1
pi@duet3:~/ustreamer $

@bearer Can I impose on your expertise one more time.

luckyflyer

Figured it out need sudo make.

But would still like to know why I can't do updates with a static ip address.

luckyflyer

@bearer
Can you take a look at this. This is from the Duet pi, same problem I had with the stand alone pi that seemed to correct its self.

I have rebooted but that doesn't seem to have helped.

luckyflyer

I've rebooted again and now is working, temperamental little sob, quitting for the night.

luckyflyer

Also wanted to ask is there a security risk when using 0.0.0.0:8080

@luckyflyer re security risk, there is always a risk with opening network services, but if you need to access the stream from a device other than the pi, then you don't have much choice in opening up. you could bind to a specific IP address instead of 0.0.0.0 but imho it won't increase the security of the setup, only reduce the convenience. also 0.0.0.0 will work even with wired and wireless networks on the Pi, and every address a dhcp server may allocate the pi in the future.

re temperamental, using systemd to start and restart it as needed will probably take care of the availability of the process.

luckyflyer

@gtj0
Can you share your Duetlapse start script with me.
Thanks

gtj0

@luckyflyer

The following 2 files will run ustreamer anytime the camera (/dev/video0) is plugged in.

/etc/udev/rules.d/80-ustreamer.rules:

KERNEL=="video0", SUBSYSTEM=="video4linux", TAG+="systemd", ENV{SYSTEMD_WANTS}+="ustreamer@%k.service"

/etc/systemd/system/ustreamer@.service:

[Unit]
Description=UStreamer for video0

[Service]
Type=simple
ExecStart=/usr/local/bin/ustreamer -r 640x480 --static /tmp/ --encoder=HW -m JPEG -d /dev/%i --host=0.0.0.0 --port=8080

[Install]
WantedBy=multi-user.target

Reboot after copying both files to their destinations.

Here's the command line to start DuetLapse and pull from ustreamer:

./DuetLapse.py -camera web -weburl http://localhost:8080/stream -duet localhost -seconds 5 -detect none

Obviously you have to customize that command line. It just captures an image every 5 seconds.

If you need to auto-start it as well, you may have to contact @Danal . I can't seem to get it to run as a systemd service.

luckyflyer

@gtj0 Thanks for that.
