Need help installing ustreamer

gtj0

@luckyflyer You don't have to specify libevent-pthreads. It's automatically installed when you install libevent

Also have you run an apt-get update lately?

luckyflyer

Yes, pi software install was new this morning with these on a stand alone pi3B+,

sudo apt-get update
sudo apt-get upgrade
sudo reboot

I want to get it right on the standalone pi before I try it on the Duet pi. I'll try just libevent.

@gtj0

I ran this,

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

and got this,

pi@raspberrypi:~ $ sudo apt-get install libevent libjpeg8-dev uuid-dev libbsd-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libevent

I'm running the full desktop version of raspbian buster.

if you're building something you probaby need sudo apt install libevent-dev ?

also could you be running into ipv6 issues, every now and then my pi or debian systems insist on using ipv6 mirrors but it usually looks different. long shot, but might help someone else stumbling onto the thread https://www.vultr.com/docs/force-apt-get-to-ipv4-or-ipv6-on-ubuntu-or-debian

That worked

which one? >D

luckyflyer

@bearer

sudo apt install libevent-dev

A Former User

confused; thats what you started with after having not just skimmed the thread. gtj0 was right then

luckyflyer

No one is more confused than I am, lol.
I think the difference is I tried this complete line

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

I did not specify -dev and also yours did not have this at the end

libjpeg8-dev uuid-dev libbsd-dev

Man I appreciate the fact that linux is compact and efficient. But it's a real challenge to figure it out. Its very unforgiving.

luckyflyer

So my question now is have I left anything incomplete by not having this bit of code included

libjpeg8-dev uuid-dev libbsd-dev

A Former User

just add them with sudo apt install libjpeg8-dev uuid-dev libbsd-dev if you don't worst thing that happens is that make fails

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.

Help please.

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?

gtj0

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

luckyflyer

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.

A Former User

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

sudo netstat -lt4np more usefull for future ref.
