• Alternative to FFMpegCore ? Combine pngs into a video

  28 novembre 2023, par HelloWorld

  I have a scenario where I want to combine a list of images into a video. I see FFMpegCore is a solution, however, I have limitations to the software I can download onto a private network and need a solution that does not require installation of software.

  


  Repo to the nuget package of FFMpegCore : https://github.com/rosenbjerg/FFMpegCore

  


  class Main
{
   public static void Main(string[] args)
   {
      string[] files = Directory.GetFiles("some path to the png directory");

      // Take this list of files and generate a video from this
      // Example of FFMpegCore would be this
      _ = FFMpeg.JoinImageSequence(output: @"newMp4.mp4", frameRate: 30, images: files);
   }
}


  


  I want to achieve something like this in .NET Core (not Framework).

  


  I tried FFMpeg and got an exception thrown due to not having the FFMPeg executable installed (which I am out of scope to do so, an organization policy)
