libomtnet is a .NET library that implements the Open Media Transport protocol for low latency, high performance Local Area Network video/audio transmission.

It is built using a basic subset of .NET and as a result supports both .NET Framework 4+ and .NET Standard 2.0+ applications, covering all .NET versions from 4 onwards.

libomt is a native compiled version of the .NET library and is available separately.

Getting Started

Installation

Official binary releases for Windows and MacOS can be found in the Releases section of this repository.

There are only two dependencies when using this library in a .NET app:

libomtnet.dll This is a cross platform file that will work on Windows, Mac and Linux

libvmx.dll (Windows) libvmx.dylib (MacOS) libvmx.so (Linux)

These are platform specific native shared libraries. The correct library for the CPU type and OS platform needs to be placed in the same directory as the application.

Creating a Source

Create an instance of the OMTSend class specifying a name
Fill the struct OMTMediaFrame with the video data in either of the available YUV or RGBx formats
Send using OMTSend.Send
That's it, the source is now available on the network for receivers to connect to

Creating a Receiver

Create an instance of the OMTReceive class specifying the full name of the source (including machine name) The full name of all sources on the network can be found by using the OMTDiscovery class
In a loop, poll OMTReceive.Receive specifying the types of frames to receive and also a timeout
Process said frames as required
