• How to convert animated webp to gif in android / java ?

  21 avril 2022, par UHS

  I want to convert the animated webp files to gif file and looking for solution since couple of days but did not get any easy straight solution yet.

  


  I tried ffmpeg but it could not do the job and after looking for solution I found that webp decoder is not implemented in ffmpeg yet.
https://trac.ffmpeg.org/ticket/4907

  


  I also checked libwebp library by google and they also says animated webp is not supported. https://developers.google.com/speed/webp/docs/dwebp

  


  I tried demo of aspose this library also fail to convert animated webp to gif.

  I think ImageMagick can convert animated webp to gif but do not know how to implement that in my project.
How can I avoid dropouts when using (imagemagick) `mogrify` to convert webp files to animated gif ?

  


  So is there any easy way to convert webp to gif

• 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'.
