Bug Report OBS Crashing, am using NDI

[NekoTV]

I will post what I posted on the git hub, maybe this isn't specifically an ndi issue.

Been having a fairly new issue. Using OBS NDI the NDI stream will freeze on the receiving end. If I try to interact with the source on the receiving end it will freeze OBS. I can add the same source and it works again, but I can't delete the old one. If I do this more than 2 times it lags like crazy (probably because the bandwidth of 3 4k streams.. OBS only crashes once I try to interact with the NDI source that has a frozen video feed. The audio from the feeds is fine. This happens at any resolution/framerate I've tried many.
On the sending end, on my gaming PC OBS is functioning perfectly. I don't even have to be streaming or recording for this video feed freeze to occur.
I am on The latest release of both obs/ndi as well as windows. NDI is the only thing I have set up to OBS besides being signed into mixer account for streamkey.
Crash 2019-11-08 14-09-54.txt
I recently fully updated my bios to the most recent. I now get random hard CTD with no error or crashlog generation. I don't even have to interact with the NDI source anymore I will mention I currently have no overclocks on cpu or memory for all the testing.

When you say "Been having a fairly new issue", I am assuming your NDI setup has been working prior to this.

According to the log file (of the attachment), the stack trace of the thread that crashed shows, OBS Web Socket was involved.

Did you do something with an UI interface to trigger this crash? Or did it happen out of the blue?
Can you do this repeatedly to cause the crash?
What happens if you do the manual equivalent without using OBS Remote Socket?
Are you running the current 4.6.1 version of OBS Web Socket (May 2019)?

Your other log file (of which you don't tell us where it came from, NDI Server? NDI Client? from same machine?) shows that it crashed in the OpenGL library that is part of the OBS distribution:

That crash happened the day before and is a separate issue. Please create a new post regarding that issue as it doesn't appear to be related and needs to be handled separately. Try to remember what you were doing to cause the crash.

I simply open OBS, and let it sit there do not interact with it at all and it crashes. both crash logs are from the receiving computer. the sending one never crashes or has any issue. The first log is BEFORE bios update, the second one is after. I don't actually use obs web socket, it is just installed. maybe that is why I actually got a crashlog, because prior to randomly deciding to install websocket I was just getting CTD with 0 crash logs.

I was correct, uninstalling websocket stopped the crashlog from generating, I will edit the main post to reflect that that isn't actually an inssue I have or care about.

 

[Sukiyucky]

You should change this post from Question/Help to be Bug Report for OBS Web Socket so Palakis is aware there is a problem.
That OBS Web Socket crashes out of the blue is not something to shove under the rug. This maybe an OBS 24.x.x issue and more investigation needed with a fix.

 

[NekoTV]

I will post the log in the websocket github issues.

 

[NekoTV]

To anyone that reads through the comments, I see that I think suki misunderstood or I was not clear enough. The crashing isn't fixed. the websocket was just a side meaningless adventure.

 

[Narcogen]

So you uninstalled websocket and it still crashes? If so, I'd post a crashlog without websocket installed.

 

[NekoTV]

That first log is with out websocket

IF you've updated the NDI plugin, you also may need to use DDU to reinstall your video card drivers.

 

[NekoTV]

I did a full uninstall of ndi, runtime, obs, nvidia driver. Full restart, full reinstall, full restart. still persists.

 

[Narcogen]

And the DDU install?

 

[NekoTV]

No change.

 

[Narcogen]

Have you posted a regular log, not a crashlog, so we can see your setup, on either the sending or receiving computer, or better yet, both?

 

[NekoTV]

okay then.

2019-11-10 13-28-45 Is the gaming pc. 2019-11-09 16-05-38 is stream pc

I have disabled "browser source hardware acceleration" under advanced as a test (on stream pc)

16:05:39.827: base resolution: 3840x2160
16:05:39.827: output resolution: 3840x2160
16:05:39.827: downscale filter: Bicubic
16:05:39.827: fps: 60/1

So.. you're trying to stream 4k60? Where to?

16:05:39.827: YUV mode: 709/Full

Probably should be 709/Partial for most users. Not sure about stability issues but this does increase load, which may be an issue for you given your resolution and framerate selections.

I don't see anything else obvious, but any performance issues aren't written to the logs if there aren't any output sessions (streams or recording). I realize your issue is crashing and this happens even without an output session, but it's possible there are things going on that could be problematic but aren't being written to the log because those statistics are only written to the log during an output session.

That and the Windows version on the streaming machine is older than on the gaming machine.

I am very new to all this (been in IT 20+ years)

I have a Surface Pro 6 running iVcam for my phone to OBS + NDI. That end seems to work fine, but the steam system OBS+NDI keeps crashing. Where are the logs I should be looking at?

Steam system is Windows 10 completely up to date
Intel i7 6850K
64gb 2400 RAM
512 950 M.2 SSD
1080 Ti video card.

I am not seeing any spikes in RAM or CPU. so I am stumped. Point me to the logs so I can figure out what is going on.

Thanks in advance.

OBS is 25.0.8
NDI is 4.5.1.0

 

[talesfromthelounge]

Here are the logs and the crash logs. I am hoping someone will see this and have an Idea. I was using the 4.9 (latest version) of NDI and downgraded to 4.8 just to test, but it does the same thing. OBS runs fine, attach the NDI source and it crashes and continues to crash everytime I reopen till I move away from the NDI source. Any ideas?

 

[xandru]

Hi, did anyone manage to fix this issue ? because I have the same problem I am trying to use vmix to output a video signal with alpha through NDI and opening it on OBS, it keeps on putting up a popup that OBS has crashed. I am using vmix and OBS on the same pc.

Thanks

 

[PaiSand]

The crash is on the NDI 6. You should contact them about it.
