  1. First, check that you have the necessary tools installed.
  2. Go to https://my.telegram.org/apps and register a new app.
  3. Clone the repository recursively by using git clone --recursive https://github.com/UnigramDev/Unigram.git.
  4. Create a new file inside Unigram/Telegram and name it Constants.Secret.cs:
namespace Telegram
{
    public static partial class Constants
    {
        static Constants()
        {
            ApiId = your_api_id;
            ApiHash = "your_api_hash";
            
            AppChannel = "Telegram channel username used for in-app updates";

            AppCenterId = "AppCenter ID used for crash data";
            BingMapsApiKey = "Bing Maps API key used for map previews";
        }
    }
}
  1. Replace your_api_id and your_api_hash with the data obtained from step 2.

Dependencies

Unigram uses NuGet for managed dependencies and vcpkg for unmanaged ones. Run the following commands to clone vcpkg:

> git clone https://github.com/Microsoft/vcpkg.git
> cd vcpkg
> git checkout 1b1ae50e1a69f7c659bd7d731e80b358d21c86ad
> ./bootstrap-vcpkg.bat

Now that vcpkg is ready, you must customize the ffmpeg port to be built with all the flags needed by the app:

  • Navigate to vcpkg\ports\ffmpeg
  • Open portfile.cmake
  • Locate --enable-libvpx and replace it with the following:
--disable-everything --enable-hwaccel=h264_d3d11va --enable-hwaccel=h264_d3d11va2 --enable-hwaccel=h264_dxva2 --enable-hwaccel=hevc_d3d11va --enable-hwaccel=hevc_d3d11va2 --enable-hwaccel=hevc_dxva2 --enable-hwaccel=mpeg2_d3d11va --enable-hwaccel=mpeg2_d3d11va2 --enable-hwaccel=mpeg2_dxva2 --enable-protocol=file --enable-libopus --enable-libvpx --enable-decoder=aac --enable-decoder=aac_fixed --enable-decoder=aac_latm --enable-decoder=aasc --enable-decoder=alac --enable-decoder=flac --enable-decoder=gif --enable-decoder=h264 --enable-decoder=hevc --enable-decoder=libvpx_vp8 --enable-decoder=libvpx_vp9 --enable-decoder=mp1 --enable-decoder=mp1float --enable-decoder=mp2 --enable-decoder=mp2float --enable-decoder=mp3 --enable-decoder=mp3adu --enable-decoder=mp3adufloat --enable-decoder=mp3float --enable-decoder=mp3on4 --enable-decoder=mp3on4float --enable-decoder=mpeg4 --enable-decoder=msmpeg4v2 --enable-decoder=msmpeg4v3 --enable-decoder=opus --enable-decoder=pcm_alaw --enable-decoder=pcm_f32be --enable-decoder=pcm_f32le --enable-decoder=pcm_f64be --enable-decoder=pcm_f64le --enable-decoder=pcm_lxf --enable-decoder=pcm_mulaw --enable-decoder=pcm_s16be --enable-decoder=pcm_s16be_planar --enable-decoder=pcm_s16le --enable-decoder=pcm_s16le_planar --enable-decoder=pcm_s24be --enable-decoder=pcm_s24daud --enable-decoder=pcm_s24le --enable-decoder=pcm_s24le_planar --enable-decoder=pcm_s32be --enable-decoder=pcm_s32le --enable-decoder=pcm_s32le_planar --enable-decoder=pcm_s64be --enable-decoder=pcm_s64le --enable-decoder=pcm_s8 --enable-decoder=pcm_s8_planar --enable-decoder=pcm_u16be --enable-decoder=pcm_u16le --enable-decoder=pcm_u24be --enable-decoder=pcm_u24le --enable-decoder=pcm_u32be --enable-decoder=pcm_u32le --enable-decoder=pcm_u8 --enable-decoder=vorbis --enable-decoder=wavpack --enable-decoder=wmalossless --enable-decoder=wmapro --enable-decoder=wmav1 --enable-decoder=wmav2 --enable-decoder=wmavoice --enable-encoder=libopus --enable-parser=aac --enable-parser=aac_latm --enable-parser=flac --enable-parser=h264 --enable-parser=hevc --enable-parser=mpeg4video --enable-parser=mpegaudio --enable-parser=opus --enable-parser=vorbis --enable-demuxer=aac --enable-demuxer=flac --enable-demuxer=gif --enable-demuxer=h264 --enable-demuxer=hevc --enable-demuxer=matroska --enable-demuxer=m4v --enable-demuxer=mov --enable-demuxer=mp3 --enable-demuxer=ogg --enable-demuxer=wav --enable-muxer=ogg --enable-muxer=opus

Now that everything is properly configured go back to the terminal and enter the following:

> ./vcpkg.exe install ffmpeg[opus,vpx]:$arch$-uwp lz4:$arch$-uwp openssl:$arch$-uwp zlib:$arch$-uwp libwebp:$arch$-uwp libogg:$arch$-uwp opus:$arch$-uwp
> ./vcpkg.exe integrate install

Make sure to replace $arch$ with either x64, x86 or arm64 depending on your build target.

WebRTC

Unigram uses WebRTC for calls and video chats. Since WebRTC doesn't currently support UWP, you must use our fork to build it.

  1. Click on Start Menu → Visual Studio 2019 → x64 Native Tools Command Prompt for VS 2022.
  2. Navigate to .\Unigram\Libraries\webrtc
  3. Execute .\acquire-m108.cmd. This will clone WebRTC source code to C:\webrtc, and it will take a while (~1.5h)
  4. Execute .\build-m108.cmd "$arch$" "$config$". Replace $arch$ with either x64, win32 or arm64 depending on your build target. $config$ can be set to either release or debug.

⚠️ Note that WebRTC build instructions are based on WinRTC.

Building without WebRTC

Since compiling WebRTC is time and resources consuming, it is possible to build the app without calls support:

  • Locate Telegram > References and remove Telegram.Native.Calls from the list.
  • From Telegram > Properties > Build, remove ENABLE_CALLS directive.
  • Exclude from the project the following files:
    • Controls/Cells/GroupCallParticipantGridCell.xaml
    • Views/GroupCallPage.xaml
    • Views/LiveStreamPage.xaml
    • Views/VoIPPage.xaml

Requirements

The following tools and SDKs are mandatory for the project development:

  • Visual Studio 2022, with
