ffmpeg was not found on your system in Azure service fabric application - asp.net-core

Question

I have a stateless service fabric application, which uses ffmpeg.exe to convert video files. ffmpeg.exe is added to the project and it's properties set to Content & Copy always. When I install the app on Azure VM (Service Fabric 5 node cluster), it has been deployed to D:\SvcFab\_App\Sample_App1\Sample.Code.1.0.0. (D drive is temp storage on Azure VM). When ever I try to convert a video file, I am getting ffmpeg.exe was not found on your system exception. I am able to convert files in development environment and on on-prem server without any exception.
I tried to access ffmpeg.exe using Path.Combine(Directory.GetCurrentDirectory(), “ffmpeg.exe”) and Path.Combine(FabricRuntime.GetActivationContext().GetCodePackageObject(“Code”).Path, “ffmpeg.exe”)

Answer 1

ffmpeg won't work unless you have it preinstalled on the vm you are using.
Once installed it will work without even needing to place the ffmpeg.exe with the source code.
If you are using a Linux VM then installation can be done using package manager.
Here I have yum as a package manager.
yum install ffmpeg
if you are using a windows VM then you have to first upload the entire folder which you have downloaded from the ffmpeg website and then you have to set the address of the bin folder to the path environment variable.
This can be achieved in command line using the following command
$Env:PATH += ";<Path to you bin folder>"
