Hi,

I am setting up a new system and I have an issue where NDI freezes for up to 7-8 seconds at random intervals. The NDI source is NDI Screen Capture. I have tried from several computers with the same result, so I don't think it is the NDI source that is the issue.
The network traffic just stops as you can see in the screenshot below.

I don't see this issue in Studio Monitor, and I didn't see it on the Tricaster TC1 this system is replacing, so I don't think this is network(Cisco with separate vlan) related. I also don't see any freezing on SDI inputs and the render time remains below 5ms through the freezing.
It happens just as much on a new empty project with only the single NDI input.

The system is a Dell Precision 5860 specced like the Obtanium reference system.

Anyone have an idea?

Thanks!

Thanks, I skimmed this, and I tried Screen Capture HX instead of the regular Screen Capture, and this works with vMix without issues.
So this could partially solve my issue. One thing Capture HX is missing is Region of Interest which I use quite a lot.

I added several HX sources to reach the bandwidth use of the normal Screen Capture and it works fine, so it is not just a bandwidth issue causing the freezing.
