How to initialize FFmpeg in .NET MAUI-Windows

[hossam14102010]

I have installed the bin using winget install "FFmpeg (Shared)" on Windows 11 22631.3810. it installs successfully but when running FFmpegInit.Initialise() I get System.NotSupportedException: 'Specified method is not supported.' I have also tried setting the logLevel to FfmpegLogLevelEnum.AV_LOG_FATAL , and I got the same exception. I tried to set the libPath to C:\Users\UserName\AppData\Local\Microsoft\WinGet\Packages\Gyan.FFmpeg.Shared_Microsoft.Winget.Source_8wekyb3d8bbwe\ffmpeg-7.0.1-full_build-shared\bin and I got the same exeption

I'm getting the same error:

I was able to get it working with version 6.0. I haven't tried others yet

PS C:\Users\iguan> winget search --id Gyan.FFmpeg.Shared --versions

same with sipsorcery-org/sipsorcery#1141 right.

Support for FFmpeg 7.x is not yet in sight, in the meantime use FFmpeg 6.x.

I have tried version 6.0 and 6.1 in a simple .NET console app:

using SIPSorceryMedia.FFmpeg;
FFmpegInit.Initialise();

and I am getting the same Exception

The problem was the PATH environment variable has value that is set to C:\Users\{UserName}\AppData\Local\Microsoft\WinGet\Links and this directory contains shortcut for FFmpeg.exe, although this works properly when I launch powershell in this directory and type ffmpeg, but this didn't work in the app. so I deleted the shortcuts in this directory and added another value to the PATH environment variable to where the winget installed the package (C:\Users{UserName}\AppData\Local\Microsoft\WinGet\Packages\Gyan.FFmpeg.Shared_Microsoft.Winget.Source_8wekyb3d8bbwe\ffmpeg-6.0-full_build-shared\bin)
