I’ve built a small OMT Player for Windows that lets you receive OMT streams (video + audio) directly over the network. The app is based on the official libomtnet SDK (thanks Martin) and uses NAudio for audio playback.

Features
-automatic discovery of OMT sources in the local network
-video rendering in a window (BGRA)
-audio playback (48 kHz, stereo)
-simple UI with Refresh / Connect / Disconnect

Download & Installation
Download ZIP

(edit):
-Unzip into any folder
-Run OMTplay-Setup

Notes:
If no source is detected (while one is running), please check your Windows Firewall. In my case, disabling the firewall or creating a rule for omtplay.exe solved the issue.
Tested with vMix (default OMT settings) – the player receives around 50–70 Mbit/s.
Runs smoothly even over WiFi6 on my setup.

(edit)
My OMTplay will only run on x64 processors.
i tested it in my local 1Gb Network, on two Win11 and a Win10 PC, all Intel with 64-bit operating system.
Since this is still very new and untested, I do not guarantee its use in production environments :-)

(edit2)
it also runs on my Asus RTX4080 Laptop and my tiny little Acer Office PC. But my little Acer, Core Ultra 5, is then hard working, CPU 60%.
(This test is going over WiFi6 , 160Mbits per connection! Your Wi-Fi must be able to deliver this.. )
no more Defender false alarms so far, from version 1.0.0.3 on.
1.0.0.4 is the same, but hides the cursor in full screen

(edit3)
it also runs on a 2017, 10x10cm Intel I5 Nuc. But the little machine has to work hard, CPU 80%. Intel 620 graphics, no stuttering on full screen.

Hi,

I downloaded your first version 1.0.0.1 and just tried to download your latest Version.
But I just want to inform you that the latest Verion is blocked by Windows Defender (Trojan:Script/Sabsik.FL.A!ml).

Best regards.

Michel

Sorry for the inconvenience! This should be due to my setup program, which uses an unusual compression method. When I google it, along with the entry Inno Setup, I find many descriptions of the alarm.
My Windows 11 system does not report any errors, but my Windows 10 system has deleted the setup program AFTER installation :-) Fortunately, the alarm allowed me to identify the cause, and I hope that it will now function properly.

I have now packed it without compression in InnoSetup and i had no more alarms. (Version 1.0.0.3, which also hides the cursor in fullscreen)

Just downloaded the new version 1.0.0.3 and no virus alert. Tested it. It is working great in windowed mode, but in Fullscreen Playback the video stutters.
Thx for your quick response.

Thx for your quick response.

What does your Task Manager say, CPU % ? Traffic wise there is no difference between windowed mode and fullscreen, only your computer has to draw it faster.
Could you tell us the specs of your computer?

CPU % is at 3%. I have Ryzen 9 5950x and a Nvidia RTX 3090. Tested it with the OMTViewer from vMix in fullscreen, and that is working fine. Tried to download your version 1.0.0.4 but again Defender alert. Do you have a changelog to your versions?
Tested also with ver. 1.0.0.1 and also have stuttering during Fullscreen.

I also tested the Player on Legion Pro Laptop over Wifi and there it is even stuttering in windowed mode. Again, the vMix OMT Player from Github has no stuttering but of course no sound.

Both tested with an 1080P25P video file (Settings: Audio: Master; Alpha Channel: None; Resolution HD1080; OMT quality: Default). Hope it helps.

(Edit)
Tested it with OBS and the OMT Plugin and everything is working fine (Video & Audio, no Stuttering) even over Wifi.
