NDISender - Performance

Thu Nov 24, 2022 4:59 am

Hi everyone,

I've just setup everything to have a NDISender on some of my scenes so that OBS can do some overrides of the MMV playlists (swapping OBS scene for one that takes NDISender instead of MMV Spout)

There is a significant performance drop when fetching NDI sender instead of SpoutV2. I have the latest NDI patch (runtime 4.5) in OBS and running an RTX3080 on an i5-8600k.

Am i doing something wrong?

Thanks
Frank

NDI is much slower than Spout. NDI should only be used between different computers. On the same computer, always use Spout.

Thanks, that explains a lot. The problem is that i wanted to send two different video streams from MMV to OBS. Is there a workaround that currently exists?
