• C# on linux : FFmpeg (FFMediaToolkit) on linux System.IO.DirectoryNotFoundException : Cannot found the default FFmpeg directory

  6 mai 2021, par Jan Černý

  I have C# project in rider and FFMediaToolkit installed via NuGet. I made instance of MediaBuilder. When I hit run I get this error message :

  


  /home/john/Projects/Slimulator/bin/Debug/net5.0/Slimulator /home/john/Projects/Slimulator/test_mazes/small-maze-food2.png
Loading file /home/john/Projects/Slimulator/test_mazes/small-maze-food2.png
Unhandled exception. System.IO.DirectoryNotFoundException: Cannot found the default FFmpeg directory.
On Windows you have to set "FFmpegLoader.FFmpegPath" with full path to the directory containing FFmpeg shared build ".dll" files
For more informations please see https://github.com/radek-k/FFMediaToolkit#setup

Process finished with exit code 134.


  


  When I go to https://github.com/radek-k/FFMediaToolkit#setup I find just this :

  


  


  Linux - Download FFmpeg using your package manager.

  


  You need to set FFmpegLoader.FFmpegPath with a full path to FFmpeg libraries.

  


  If you want to use 64-bit FFmpeg, you have to disable the Build -> Prefer 32-bit option in
Visual Studio project properties.

  


  


  I have already installed FFmpeg package via pacman and I am still getting these error.

  


  How can I fix this so I can use FFMediaToolkit without problem on linux ?
  
Thank you for help

  


  EDIT1 : I use Arch linux.
EDIT2 : There is related issue on github : https://github.com/radek-k/FFMediaToolkit/issues/80
