Question / Help [SOLVED] OBS not reloading ip camera stream

Ground Loop

New Member
Hey guys,
I'm on Windows 7 64-bit
OBS 19.0.3 32-bit
VLC 2.2.2 32-bit
I've been experimenting with OBS for a continuous live stream of an ip camera, but for the life of me I can't get it to auto-reconnect to the camera's RTSP stream whenever the connection is temporarily lost.
This happens ocasionally due to network glitches or a power failure.

I tried both the "VLC Video Source" and the "Media Source" options, while fiddling with their parameters back and forth.
Neither of them reconnects...
- Media Source at least goes transparent when the connection is lost, and that is what I want.

Can you help?
Thanks in advance.

Code:
01:16:24.984: [Media Source 'Media Source']: settings:
01:16:24.984:     input:                   rtsp://192.168.1.64:554

01:16:24.984:     is_clear_on_media_end:   yes
01:16:24.984:     restart_on_activate:     yes
01:16:24.984:     close_when_inactive:     yes
01:16:24.984: MP: Failed to open media: 'rtsp://192.168.1.64:554'

Ok, since no one is coming up with ideas, I think I can make a workaround.

How about this:

OBS settings --> hotkeys:
Show Media Souce: CTRL+ALT+SHIFT+S
Hide Media Source: CTRL+ALT+SHIFT+H​

Then, a script with the following behavior:
//// Monitoring the TCP connection between obs32.exe and the ip camera (RTSP port 554) ////
- While "Connection state" is "ESTABLISHED" --> keep querying the connection state every 10 seconds.
- If "Connection state" changed to something else:
- Send Hide hotkey (this stops the media and makes it invisible)
- Do this (until it works):
- Ping the camera's ip address
- If ping is ok --> attempt to open port 554
- If port 554 is opened --> ok, close it​
- Send Show hotkey (this attempts a new connection in OBS)
- Wait for 10 seconds
- Loop from the beginning.

I will attempt to implement this in a couple of days, and then I'll report back.

Hi,

I have the same problem with the IP camera. It works for a couple of hours and does not reconnect automatically.

Here it is. Something to work on, but it does the job.

Written in AutoIt.
- You need to install AutoIt in order to compile/run this script.
- I recommend you also install SciTE to edit the file (to set some variables such as camera's IP address).​
Tested under Windows 7 64-bit (x86).
Should work on WinXP and above.
No VLC required.

Thanks for the workaround, I am about to give it a try.
But first I have to understand this completely ;-)

Does it matter which version of AutoIT I use to execute the script? Or use the same as obs is installed?
Running multiple scripts for 2 or 3 cameras is okay?

thanksalot

source is an rtsp-stream, so no loop-function available.
"restarting the source if source becomes active" is activated.

I see in the AutoIT-script that this code is also scene-based.
So it will be necessary to execute one script per scene?
And how to handle a IP Cam if it is present in two or more scenes?

[EDIT] shortcut = hotkey

Does it matter which version of AutoIT I use to execute the script? Or use the same as obs is installed?
In the official AutoIt site, there is only one AutoIt installer available for download, and that's the one you should install.
AutoIt --> Downloads --> AutoIt full installation

Running multiple scripts for 2 or 3 cameras is okay?
Haven't tested, should work, but:
- the script checks if obs32.exe is running, and starts obs32.exe if it's not. Multiple scripts will be doing this. Not a big concern, but just so you know, it would be better to rewrite the one script to support multiple cameras.
- you need to create a different hotkey for each camera, and adjust each script accordingly.

source is an rtsp-stream, so no loop-function available.
"restarting the source if source becomes active" is activated.
Indeed I confirm that no option in OBS works flawlessly, neither with Media Source nor with VLC source.
Eventually the VLC source stopped working altogether. Just a frozen frame. But VLC standalone runs fine.

I see in the AutoIT-script that this code is also scene-based.
So it will be necessary to execute one script per scene?
And how to handle a IP Cam if it is present in two or more scenes?
The script isn't scene-based. It's:
- process-based - checks that obs32.exe is running;
- IP-based - checks that obs32.exe is connected to the ip camera on the specified port;
- and hotkey-based - sends the hotkey to hide/show media when the IP connection is lost and then reestablished.

Hi,

I tried the above script and it does not work for me.

It will restart the camera once when I run the script.

Can you please help please.

Thanks,

Thanks for this script Ground Loop. I have been successful in deploying this with multiple cameras and it appears to work well as a workaround. I did modify it a bit as you suggested with regard to only checking once if the instance of OBS is running and then each camera connection separately. Wish there was more effort with regard to RTSP stream and making sure it is restarted properly upon disconnection from dev's of OBS, as I feel it is vital for anyone looking to use OBS in a live cam stream scenario. Until then, this can be a temporary bandaid to keep it limping. Thanks again for sharing!
 
I had the exact problem with three Ubiquiti Aircams running on Firmware 1.2.

OBS Studio would always loose comnnection and the frame would freeze, no matter what settings I choose. I then deleted all sources and added the cams back as VLC sources and now it works. Even when I reboot the cams while livestreaming OBS Studio picks up the stream a few seconds afterwards and continues as nothing has ever happend.

Hope this helps someone.

This is riddiculous. OBS Classic did not have this issue at all. All of a sudden OBS Studio cannot reconnect to a RSTP stream (there are reports about the issue from a long time ago, this is not the only ), someone writes a crazy workaround out of the box and half a year later the problem is still there. I was even reported on the bugrtracker but ended with... no priority.

I know, right?
And the solution seems simple enough to implement into OBS.
However, this is free software, and it's up to the developers to choose what they want to spend their time with.

Back in August 2017, I've tried what Manuel mentioned above, but it didn't work for me.
Still, I'm glad that we have workarounds, and a couple of people did manage to make it work one way or another.

Sorry for not replying here in a while. The script has been working flawlessly for me since then.
24/7 never touched that computer again :)

Actually I think you're quite on the money (pun intended); donation-based development.
With cryptocurrency they could open a new wallet for each request, and essentially donations could serve as priority votes.
They could even set donation targets, or even smart contracts for that (kickstarter style).

Although for the time being I'd favor something other than Bitcoin or Bitcoin Cash. Average per transaction fees at current USD rates:
BTC fee: 10 USD
BCH fee: 0,20 USD
ETH (Ethereum) fee: 1,06 USD
LTC (Litecoin) fee: 0,30 USD
XLM (Stellar Lumens) fee: 0,00001 USD

This creates a trust issue however; dev teams could in theory "implement" bugs in order to collect $ for fixing them.

Hello,
How are you?

Please, where I put the script?
Inside OBS....where? A folder?
Thanks for attention and help

The script goes wherever you want it to.
Read the post, you need to install AutoIt.
If you're not technically inclined, you'll have to spend some time figuring out what to change for your case.
It's not "plug and play".
You need to set the variables for the OBS location, and camera IP address and so on.

[EDIT] shortcut = hotkey


In the official AutoIt site, there is only one AutoIt installer available for download, and that's the one you should install.
AutoIt --> Downloads --> AutoIt full installation


Haven't tested, should work, but:
- the script checks if obs32.exe is running, and starts obs32.exe if it's not. Multiple scripts will be doing this. Not a big concern, but just so you know, it would be better to rewrite the one script to support multiple cameras.
- you need to create a different hotkey for each camera, and adjust each script accordingly.


Indeed I confirm that no option in OBS works flawlessly, neither with Media Source nor with VLC source.
Eventually the VLC source stopped working altogether. Just a frozen frame. But VLC standalone runs fine.


The script isn't scene-based. It's:
- process-based - checks that obs32.exe is running;
- IP-based - checks that obs32.exe is connected to the ip camera on the specified port;
- and hotkey-based - sends the hotkey to hide/show media when the IP connection is lost and then reestablished.
What needs to be changed to make two instances of the code work? I have one instance of it working perfectly. But when I try to open a second code for another camera it will not open. It will only let me run one code at a time.
