[Bug]: NDI-OBS freezing/crashing

[Rotund]

Operating System Version

Windows 11

OBS Version

29.0.2 and 28.1.2

NDI Tools Version

5.5.3.0 and none

Describe the bug

The OBS-NDI plugin freezes so that the video stops updating on the NDI Sources. Then when attempting to close OBS, the obs-ndi plugin will keep OBS from closing. (Sorry, I had a stack trace log but not with me. It included the plugin shutdown function though.) During this time, the display capture and DroidCam plugins keep updating. Using NDI Tools/Monitor, the cameras are still updating. The freeze usually happens within the first hour of use but could be first 5 minutes.

NOTE: We don't seem to have this issue w/ the 4.10 obs-ndi plugin.

We're using Mevo Start cameras configured to use NDI|HX and low latency mode.

There are mentions of other people with the same issues on the OBS forum: https://obsproject.com/forum/threads/obs-ndi-newtek-ndi%E2%84%A2-integration-into-obs-studio.69240/page-47

Steps to reproduce

Expected behavior

It shouldn't freeze and crash the plugin.

I will soon release a 4.12.0 version w/ updated NDI lib that might help/avoid this.

You can try out 4.12.0 Release Candidate if you want.

The Pull Request #919 has been labeled with "Seeking Testers" and the build generates installer packages that you can download try out.

Steps:

1. Browse to Preparing for 4.12.0 release #919
2. Click on "Show all checks"
3. Click on any of the "Details"
4. Click on "Summary"
5. Scroll down and see the "Artifacts"
6. Download the relevant Linux/MacOS/Windows artifact for your platform
7. Windows may complain that the download looks suspicious; you may safely ignore
8. Unzip the download
9. Run the installer

Is this still an issue using 4.13.0?

I would test this for you but I don't have an install file for 4.13.0 to roll back to, unless you can provide said file.

Sorry, been running around on other tasks for the last month. I'll try to look at it soon.

Sorry. Didn't mean to close.

Yes it is still an issue in 4.13.0; I tested 2 different setups. Same results both times.
