Need help installing ustreamer

luckyflyer

I ran

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

and got this,

The following NEW packages will be installed:
  libbsd-dev libjpeg8 libjpeg8-dev

Finally I think I'm getting there.

Succuss, Got ustreamer to compile.

luckyflyer

I've got ustreamer compiled and it is supposed to default broadcast on http://127.0.0.1:8080
I get,
This site can’t be reached 127.0.0.1 refused to connect.
This is on chrome and edge doesn't connect either. I have temporarily disabled the firewall but still no connect.
When I try a different ip address with the start script for example 192.168.0.116:8080 I get

ERROR [127.103 main] -- Can't bind HTTP on [192.168.0.116]:80: Cannot assign requested address
I've tried other address's also with the same result.

Ustreamer doesn't show anything wrong on http://127.0.0.1:8080
below is its startup.

only works on the pi, not from any other computer/device.

dwc is probably already using port 80 so (for unknowna and unrealated reasons the script) is ignoring your :8080 somehow, should probably specify it as --host=0.0.0.0 --port=8080 to bind to all available ip addresses and port 8080?

Here's the command line I use...

/usr/local/bin/ustreamer -r 640x480 --static /tmp/ -m JPEG -d /dev/video0 --host=0.0.0.0 --port=8080

I tried chrome that's on pi (this is a standalone pi not the Duet pi) @ http://0.0.0.0:8080 and ustreamer works perfectly both snapshots and stream look good.
I just need to figure out why I can't get to that address with my pc.

A Former User

@luckyflyer 0.0.0.0 isn't a valid IP address - won't work on your pc, surprised it works on your pi tbh.

but if you used --host=0.0.0.0 it would bind to all ip addresses on that host, incl 192.168.0.116, so try http://192.168.0.116:8080/ ?

luckyflyer

I tried http://192.168.0.116:8080/ and a couple of other address's within the same range ie ending in 116, 140 and 180 on both the pc and pi and neither could connect, made sure nothing else is on that addr.

@luckyflyer what does ~~netstat -lt4n~~ say on the pi?

sudo netstat -lt4np more usefull for future ref.

@luckyflyer would appear ustreamer isn't bound to any ports?

pgrep ustreamer?

luckyflyer

@bearer said in Need help installing ustreamer:

pgrep ustreamer

Run that command?

A Former User

@luckyflyer yeah, it'll return the PID for ustreamer if its running.

luckyflyer

I believe I'll have a problem doing that because when ustreamer is running terminal is locked until a cont C .

luckyflyer

Tried it didn't work.

luckyflyer

Tried it on pi's terminal with ustreamer running but command did not return anything

A Former User

it wont when ustreamer isn't running, which was the goal to confirm as netstat didn't show anything bound to 8080.

methinks you ~~need to~~ should review https://github.com/pikvm/ustreamer#tips to run this as a systemd unit

luckyflyer

I ssh into terminal on my pc and start ustreamer I then go in via vnc to terminal and enter pgrep ustreamer but didn't return anything.

luckyflyer

Ok I'll read that again

A Former User

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

instead of pgrep?
