  • pip install av produces a LINK 1181 error

    6 février 2020, par user8606643

    initially, pip install av asked me to download visual C++ 14 build tools which I did
    but it is still showing me LINK 1181 errors

    I need this pyAV pakcage which is obtained by pip install av for a project, but it always shows some kind of error linked with C++ and i also have ffmpeg installed.

  • Android App Bundle build error : File 'root/lib/x86/ffmpeg' uses directory name 'lib'

    7 septembre 2020, par Patel Pinkal

    I have used FFmpeg Android in the project from this repo FFmpeg-Android-Java and implement only the FFmpegAndroid module in the project.

    


    FFmpeg library is working fine when we run directly from Android Studio or we make APK file (debug or Signed).

    


    But When I try to generate the app bundle from Android studio I get the below error.

    


    Execution failed for task ':app:packageReleaseBundle'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
  > File 'root/lib/x86/ffmpeg' uses reserved file or directory name 'lib'.

  • A third-party library (FFMpeg) is spamming output

    14 janvier 2015, par Maciej Stachowski

    I’m using otherwise brilliant AForge library in my console project to encode video. When I run the project from under Visual Studio (both in Debug and Release modes), it works fine. However, running it as a stand-alone application produces the following :

    errors

    (the prompt being in the third line is an artifact of me using Console.SetCursorPosition extensively).

    As far as I can tell, there’s no way to configure ffmpeg from under AForge to avoid this error, and the resulting video files are fine anyway, so I’d like to simply shut it up.

    It seems, however, that even setting

    Console.SetError(StreamWriter.Null);
    
Console.SetOut(StreamWriter.Null);

    does nothing - my app is trying to write something in the first two lines (another oddity), but gets spammed out by ffmpeg output.

    Can I do anything about it ?
