• System.InvalidOperationException thrown when running as part of a WPF application. Xabe.FFmpeg

  16 mars 2021, par S. O. James

  I have the following code which runs on a console application

  


    string filePath = "C:\\Users\\**\\Desktop\\sample-mp4-file.mp4";
  string output1 = "C:\\Users\\**\\Desktop\\1.jpg";
  string output2 = "C:\\Users\\**\\Desktop\\2.jpg";
  var ms = new MultiSnapshotCommand(filePath);
  await ms.Add(TimeSpan.FromSeconds(20), output1);
  await ms.Add(TimeSpan.FromSeconds(20), output2);
  await ms.Invoke();


  


  Which uses the following

  


    public async Task Add(TimeSpan timestamp, string outputPath)
  {
      var conversion = await FFmpeg.Conversions.FromSnippet.Snapshot(filePath, outputPath, timestamp);
      conversionQueue.Enqueue(conversion);
  }


  


  This executes fine and both snapshots are created when calling Invoke().
However, when executing the same code running in an async method in response to a button click in a WPF scenario, the UI freezes, then a few moments later Exception thrown: 'System.InvalidOperationException' in System.Diagnostics.Process.dll is shown from the debugger output with no recovery.

  


  The error seems to be occurring at await FFmpeg.Conversions.FromSnippet.Snapshot(filePath, outputPath, timestamp);

  Edit

  


  My project files https://github.com/Scharps/MP4ToImageConverter/tree/05beeb1cc359b654fb51a9695b5c20386c4d5fb6.
FFmpeg is required in Path system variable. File locations will need to be changed also

• CANNOT LINK EXECUTABLE - ffmpeg - Android

  13 avril 2018, par pudility

  I am getting the following error when I try to use ffmpeg on Android.

  Error

  09-02 18:06:33.805 2861-3659/com.gitlab.onreg01.ffmpegsample D/FFmpeg: Running publishing updates method

  Platorms

  I am running OSX (not sure if this is important)

  I have tried running the app on the following emulators all to no avail :

  • Nexus 5X - API 25 - x86
  • Nexus 5X - API 23 - x86
  • Pixel 5X - API 26

  What I have tried

  • Restarting my computer and android studios and running Invalidate Caches / Restart...

  • Using all of the following sources for ffmpeg (individually and together) :

    • compile 'com.writingminds:FFmpegAndroid:0.3.2'
    • AAR file from here
    • .jar file from here
  • Enabling and disabling NDK
  • Changing the SDK versions

  Sources

  In case you would like to take a look at the sources, the ones I am using are available here. Please note I did not make these all credit goes to @Onregs.
