OK! By using an earlier version of NDI in Windows, at least the VLC Output is now clean (still need to set the ratio manually to 16:9)
Additional i saw that zoom does not offer 1080p Streaming for all users.

The Results i had with the Linux test, could be explained by the size (720p) and added a strong shitty compression. :)

I'm starting to think is the same for everyone but nobody seems to use for desktop/text sharing?
Same bad quality resolution with NDI plugin and Virtual Input.

OK! conclusion. I Tested now on a second machine with a all UpToDate setup. To make it short!
Here is a Tutorial to verify that OBS and NDI is not the Issue.

Make shure you have set the Output and scaling in OBS to 1080p

Plugin: Virtual Camera
start blugin no settings needed!

Plugin: NDI
make shure after you started to plugin to set in the Virtual Input client the video also to 1080 (right bottom corner of your desktop)

Test device: Show Output Picture in VLC the CORRECT way (I use the German version, so maybe the words differ)!
VLC> FILE> open capture device (ctrl+c)> Change video device to NDI/virtual camera> click advanced options> Set ratio from 4:3 to 16:9> OK > Play!

Now you see the Output your Plugin is giving to all other programs.

OK, just Installed a fresh windows 10 1903 and the error is back! Funny Thing... Using older version of OBS (24.0.3) gives better results!

I tried a bunch of different things (my monitor is 2K and I even try to reduce to 1080 with the same results), and nothings seems to work.
I'll try the YUY2 thing you mentioned!

I will write later how to set the colorformat manually in vlc.
The issue is related how windows Interpret the colorformal. If i open the ndi stream on a second pc in the network, the output is flawless.

If i open it on the local vlc the output is unusable!

Testing NDI+VLC with UYVY, everything works how it should. I don't even need to change the video output en OBS to 1080. Works a little bit cleaner with 1440 in video base and output. The question is the same you asked in the other threat: How can we put that colorformat as default?

Thing is, all my other Systems play YUY2 without any issues. I saw that Win 10 has/had issues playing YUY2 .

This time, I setup a clean Win10 1909, just installed NVIDIA Drivers and OBS+NDI and VLC. This bug come right away!
It is a DirectShow decoding error i think.

I have two pc. I9 9900K and laptop dell XPS 2019 i7 all updated, nvidia, w10 1909, zoom, obs, scripts, plugins... behaviour is exactly the same.
I’ll test an iMac in a while and post.

It seems to be a little more complicated in MacOs than windows and with Catalina is a pain in the ass.
I did not figure out how to do it yet without disabling SIP...
