Could not load file or assembly 'accord.video.ffmpeg.x64.dll' or one of its dependencies

I'm using Accord.video.ffmpeg.x64. My project is built in x64 as well. It is a click once windows forms application. I installed accord through nuget. C++ redistributor is installed.

Everything works fine when I run the program from debug. But when I publish it and try to run it (on the same machine or any other machine) I get the error "could not load file or assembly 'accord.video.ffmpeg.x64.dll' or one of its dependencies."

Thank you for any help you can provide.

Maybe the library depends on another library and it can't find it. Try to open your application with the 64 bit version of dependencywalker. - Isma

Install on the machine both

  • vc_redist-2015.x64.exe
  • vc_redist-2015.x86.exe

and copy all files from your Nuget packages folders

  • packages\Accord.Video.FFMPEG.x64.3.8.0\lib\net(Version)
  • packages\Accord.Video.FFMPEG.x64.3.8.0\build

to the installation folder of your application.
