• FFmpeg java.lang.UnsatisfiedLinkError dlopen failed : library "libavutil.so" not found in Vivo model device

  9 février 2024, par sejn

  Facing a lot of crashes in the Android Vivo devices with the above error. Can I restrict this to the Vivo models in Android.

  


  I'm using the implementation 'com.arthenica:mobile-ffmpeg-full:4.4'

  


  Fatal Exception: java.lang.UnsatisfiedLinkError dlopen failed: library "libavutil.so" not found

init {
    try{
        System.loadLibrary("avutil")
        System.loadLibrary("avcodec")
        System.loadLibrary("avformat")
        System.loadLibrary("swscale")
        System.loadLibrary("avfilter")
    }
    catch (e:Exception){
        Log.i("error","${e.message}")
    }
}


  


  In app/build.gradle

  


  


  ndk 
abiFilters 'armeabi-v7a','arm64-v8a','x86','x86_64'

  


  


  Note : If I migrate to the latest version ffmpeg-kit-full:6.0-2

  


  Clarifications :

  


  

  1. Shall I need to add this below in the code as well if I use the FFmpeg-kit

  


  2. If I did not need to use means, does it make any issues in the app ?.(i.e) if I removed

  


  3. Shall I need to add any additional loadlibrary in the init ?

  


  4. Is there any simple fix for the above error for Oppo alone without migrating ?

  


  5. Shall I need to add these architectures in ndk of my app ?

  


  


  


  arm-v7a, arm-v7a-neon, arm64-v8a, x86 and x86_64 architectures

  


  


   init {
        try{
            System.loadLibrary("avutil")
            System.loadLibrary("avcodec")
            System.loadLibrary("avformat")
            System.loadLibrary("swscale")
            System.loadLibrary("avfilter")
        }
        catch (e:Exception){
            Log.i("error","${e.message}")
        }
    }

• Finding start point in audio file with ffmpeg

  4 juillet 2019, par jovadeza

  I’m trying to determine the starting and end point in an audio file with ffmpeg. My definition for start and end point is when the song reaches -27dB. I have tried multiple ffmpeg audio filters, but without the desired result.

  The closest I got was when using the following command :
  ffmpeg -i song.mp3 -af silencedetect=n=-27dB:d=0.2 -f null -

  However, this returns multiple values, since the song can get silent in the middle of the song as well.

  So, I only want to get the first time the song reaches -27dB and the last time the song reaches -27dB.

  ---

  See image with example markers, created manually in Adobe Audition. Marker 1 : song reaches -27dB for the first time, marker 2 : song reaches -27dB for the last time. This are the positions in the song I am trying to find, trough ffmpeg

  

  Thanks !
