Blank NDI inputs

[mossey]

On windows, Freeshow is able to detect Ndi sources but not able to display the sources. The signal displays the loading animation but is never loaded.

I have had no success with local Ndi sources running on the same PC as well as the others on other pcs but within the same network.

The same NDI signals are visible and play on a Mac and on the NDI monitor on the same PC and on the Mac.

I have no issue sending my screens out of Freeshow via NDI. I am able to detect and receive the sources with no hitch

I have checked the windows firewall and made sure to have it allow get inbound traffic but this does not get the video signal to play.

Additionally, I have reinstalled Ndi tool and Freeshow but the issue persists.

Important to mention that this was attempted when the laptops are connected via an Ethernet cable.

Reproducing
Running Freeshow version 1.3.0 on windows 11. Go to NDI sources. You may see your Ndi sources but the video stream is not playing at least for my case...

It works just fine in my tests on Windows 10, so I'm not sure what the issue could be. 🤔

What I am experiencing and my firewall tools

[vassbo]

👍 Your configuration seems fine. And the inputs are properly detected, I'm not sure why they won't load..

[mossey]

Right, FYI, this is the second PC I have tried on with no luck. The PC was running windows 10.

I had similar problems with NDI output yesterday.
I found out my NDI version is too old.
Everything works well after I uninstalled the old version and installed the latest NDI tools.

Thank you @AngangGuo.
@mossey Have you updated to NDI 6?

[mossey]

Hi @vassbo I'm on NDI 6

i have the same issue on linux, using distroav ndi 6.0.0, the streams from obs (testing with this) are detected correctly, but won't display when clicked. freeshow sort of locks up when i attempt it, high cpu usage even after esc/clear all. no other shows will display after attempting to load the ndi stream. i ended up forcing it to close (alt+f2, pkill -9 freeshow) let me know if you need more info.

[vassbo]

Still not sure why this happens..

Similar issues were repoted here (arm64 Linux):

I have the same issue on Windows 10. I wonder if there is a way to get more verbose logs from Freeshow or the NDI connector.

I'll also try to run Freeshow as Administrator to see if it works

[yurividal]

Running as dmin didn't help.

Here is what freeshow logs says:

		{
			"time": "2024-11-26T20:26:06.713Z",
			"os": "win32",
			"version": "1.3.2-beta.1",
			"active": {
				"window": "main",
				"page": "show",
				"show": null,
				"edit": {
					"items": []
				}
			},
			"drawer": {
				"active": "media"
			},
			"type": "unhandledrejection",
			"source": "See stack",
			"message": "Could not start video source"
		}

Perhaps you can make that stack trace print the exception in the logs, which will probably give us a bit more info.

Just out of curiosity, is your Win10 PC Intel or AMD?

[vassbo]

AMD, I think the video source can't start because the input feed is invalid. The problem is most likely the NDI package!

I have tested on both Windows 10 & 11, and it works for me (Both AMD).
The inputs load fine, and the one webcam I set to a test pattern loads (the other NDI webcams gives this result as I have not set any input: #1061 (comment))
