How to build the WebRTC/WinRTC fork Unigram uses from available source. This is based on current source available as of 2021-12-05.

Building Unigram WinRTC.md

Given Unigram reliance on WebRTC (and more precisely WinRTC) and forked changes, that are not clearly documented, this guide will help you build WinRTC yourself with the right changes that Unigram needs in order to work.

Preliminary

In order to make some file replacements easy, feel free to download a copy of this gist.

Build Status for Unigram.WinRTC

Target	Status
UWP x64	✅
Win32 x64	✅
UWP arm64	✅
Win32 arm64	✅
UWP x86	✅
Win32 x86	✅
UWP arm	❌
Win32 arm	❌

ARM32 Windows is not currently supported by the WebRTC source and would likely require more patches

Getting started

Install Latest vs_buildtools.exe for Visual Studio 2019 (Include UWP workload, and VC++ build tools for x64 x86 and arm64, as well as 18362 SDK and 22000 SDK)

Make sure you install it under C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview as the scripts depend on this specific path.

Run the following commands

cd c:
git clone https://github.com/FrayxRulez/winrtc.git winrtc

Replace the following files with attached copies:

• c:\winrtc\.pipelines\restore-acquiring_code.cmd
• c:\winrtc\.pipelines\restore-applying_patches.cmd
• c:\winrtc\.pipelines\build.cmd
• C:\winrtc\patches_for_WebRTC_org\m84\patchWebRTCM84.cmd

Run the following commands

c:\winrtc\.pipelines\restore-acquiring_code.cmd
c:\winrtc\.pipelines\restore-applying_patches.cmd

If you want to have ARM64 support

The original WinRTC repo had a patch for disabling neon due to it being broken and not buildable with MS compiler. Unfortunately WebRTC changed a lot since then and the patch doesn't apply, and is too little to fix the issue. Below are guidance on how to fix it yourself. (Ignore if you do not care about arm64)

See ARM64 File Changes

Building time!

Run c:\winrtc\.pipelines\build.cmd

Packaging time!

• Download nuget from https://dist.nuget.org/win-x86-commandline/v6.0.0/nuget.exe
• Place nuget.exe under C:\winrtc\NuSpecs
• Run the following commands under C:\winrtc:

set CDP_PACKAGE_VERSION_NUMERIC=91.0.0
set CDP_BUILD_TAG=pre
.pipelines\package.cmd

You should get .nupkg files under C:\winrtc\NuSpecs :)
