Ubuntu Server when try connect to rtsp got 503

[sea-kg]

Server Side:

$ gst-launch-1.0 --gst-version GStreamer Core Library version 1.8.3

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.2 LTS
Release:    16.04
Codename:   xenial

Run camera_emulation_server

$ sudo ./camera_emulation_server -l 185.53.169.* -b 554

And after I try on client side:

 $ ffplay rtsp://185.53.169.*:554/live.sdp

But got:

method DESCRIBE failed: 503 Service Unavailable
rtsp://185.53.169.*:554/live.sdp: Server returned 5XX Server Error reply

Can you help me what's wrong?

I think using a wildcard in the address argument is probably the reason why this doesn't work. Why did you try using a wildcard here when launching your CES?

[jstoja]

Hello @sea-kg ! I think that you're trying to bind and address 185.53.169.* to avoid exposing it to another subnet, but we're not handling wildcards for bind addresses (because it is incomplete and would mean that we need to know the network mask too).

What you can try is setting the whole IP address of the machine you're using. This would bind correctly to the machine ;) For example:

sudo ./camera_emulation_server -l 185.53.169.42 -b 554

Let us know if it works!

[sea-kg]

Hello @jstoja,

Yes of course I set full address. I just masked my ip address in comment up))) ok. last part of ip-address 102 - you can try connect.

And I can say that before I do same but in local network - and it work but on real server - not work.

Please tell me know if you will be need more information.

[jstoja]

Can you check that you're actually correctly binding to the address and port? (with netstat -ntpl) I just tried and it worked.

I also can see that you have 500 errors, do you have some logs on the camera_emulation_server ?

[sea-kg]

I already checked firewall... ;)

$ sudo netstat -tnpl | grep 554

It's all that applciation printed:

(I added the bug log even though we don't know yet if the issue comes from our software or from the network configuration, to make it easier for users that might experience the same problem to find it later)

[Ullaakut]

@sea-kg Try setting the GST_DEBUG environment variable to 3 on the machine that runs CES, and restart CES, then show us the ouput (it will probably be super long but no worries)

Hi @sea-kg,

The error is: 0:00:03.054994995 9862 0x1df8ca0 WARN rtspmediafactory rtsp-media-factory.c:1184:default_create_element: recoverable parsing error: no element "x264enc"

We were missing a dependency in the readme: gstreamer1.0-plugins-ugly Readme was updated accordingly. Thanks for your feedback

Gegon

[Ullaakut]

Issue https://github.com/EtixLabs/CES/issues/10 will contribute to make everything easier by not having any other dependency that docker.

I consider this issue fixed, please let us know if gegon's solution doesn't fix your problem.

[sea-kg]

Thanks! Now is work!

[Ullaakut]

A pleasure, thank you for using CES :) Don't hesitate to tell us if you have other issues!
