Since upgrading to vMix 25 I've been finding that on most occasions, when I quit vMix, the application become unresponsive and I have to use the Task Manager to kill it.

If I've changed anything I get prompted to save my preset (and if I do so, the save works), but then the window just remains there until killed with Task Manager.

Windows 10, using NDI for both inputs and output, other than that everything is pretty vanilla.

Any ideas?

By crash, do you mean the application hangs up and you have to kill it in task manager or does it cause a BSOD? Our computer goes to BSOD upon closing Vmix about 50% of the time. I'm not sure if it's a hardware issue or related recently updating to version 25 since we recently upgraded our capture card.

This is happening for us as well. Anytime a midi controller is connected, vmix 25 becomes unresponsive when closing and needs to be shut down with the task manager. If the midi controller is disconnected prior to closing, vmix 25 closes properly. A fix would really be appreciated as we don't always remember to disconnect the midi controller!

Any solution to the problem? I have the same issue. Started when we upgraded to version 25, and don’t have a license to upgrade to 26…

Yes, that happened to me before, and if you try to kill vmix on task manager it shows an error message related to an unknown object and closes quickly, can't send the error report. that was the reason that i needed to leave srt behind

Yep, saw this on v25, but not that often; now after upgrading to v26 we saw it a lot more - nearly every time!

We use NDI for 2 PTZ cameras and sometimes a remote laptop screen capture.
We have 2 export channels turned on for NDI
We don't use SRT inputs or exports (correct me if NDI is SRT)

After upgrading to the very latest v26.0.0.45 on 31/07/2023 and after starting and stopping a vMix preset numerous times, it closed cleanly every time.

I live in hope, but would be interested if anyone has updated their version to v26.0.0.45 and still gets the issue.

+1'ing this to say it can happen in vMix 26 too.


A clients PC of mine which is running vMix will HANG/CRASH on exit if there is a 'Stream > VLC' input added (which I'm using to pull SRT's from a Zixi Broadcaster, due to the OTHER issue of vMix not liking SRT's generated by Zixi Broadcaster).


And when I say hang/crash, I mean it will literally just freeze there. I get absolutely no error message, the Windows event viewer/application logs say absolutely nothing about a crash or provide any useful information.
The only way to get the application to close is literally force killing the process in Task Manager.



I will concede this is on 26.0.0.44 - I'll have to try updating to .45 and see if that resolves it.
However, the .45 notes don't mention fixing a bug like this.

Did you check and make sure you don't have any of the issues identified above?

If you DO have one of those issues then you should identify that you have that particular issue. In my case it was an SRT input, since the sending device had other output options I just switched to one of those in place of the SRT option.

Once they fix the issue I would like to go to SRT but by then I may be replacing the cameras and will go for NDI whenever possible.

I have found that if before closing the VMIX software I disconnect the USB from the El Gato Stream Deck keypad, it allows me to close VMIX correctly.

The problem I had was not with an SRT Output but an SRT Input. Have switched to NDI inputs since then.
