• How do I set a relative path for an .SO file ?

  1er juillet 2015, par Eran Boudjnah

  This is my error :

  06-29 16:52:37.729 24144-24144/com.my.app E/AndroidRuntime﹕ FATAL
  EXCEPTION : main
  Process : com.my.app, PID : 24144
  java.lang.UnsatisfiedLinkError : dlopen failed : could not load library "build/obj/local/armeabi/libavformat.so" needed by
  "libFFmpegWrapper.so" ; caused by library
  "build/obj/local/armeabi/libavformat.so" not found

  build/obj/local/armeabi/libavformat.so looks wrong to me. The code worked with an earlier build of ffmpeg - so I suspect it’s something to do with the way I build ffmpeg.

  The libavformat.so file is in the APK where I’d expect it to be.

  This is my build script for ffmpeg :

• The HLS segment filename file path not incrementing

]);


  


  Here I'm using the spawn of a child process of FFMPEG I need to transcode the video input into four different resolutions in m3u8 format. There will be master.m3u8 and folders v0, v1, v2, and v3 ; inside those folders, there should be pro_index.m3u8 file and multiple file-sequence files according to input file size

  


  The HLS segment filename is not incrementing properly So the process is failing

  


  how to increment fileSequence file names ?
fileSequence%d.ts or fileSequence%03d.ts in not work here

  


• 2 files found with path 'lib/arm64-v8a/libc++_shared.so' from inputs...-react native

  19 septembre 2024, par CrackerKSR

  I am trying to enable package of ffmpeg-kit-react-native in react-native.
The sample commands given in the example executes successfully. But I want to use libwebp for converting gif files to webp which is under package named video. As instructed . I have to enable the package to use some libraries.

  


  


  2.2.1 Enabling a Package on Android
Edit android/build.gradle file and add the package name in ext.ffmpegKitPackage variable.

  


  ext {&#xA;   ffmpegKitPackage = "<package>"&#xA;}&#xA;</package>

  


  


  So I added a line in the node_module/ffmpeg-kit-react-native/android/build.gradle

  


  android {
  compileSdkVersion 30

  defaultConfig {
    minSdkVersion safeExtGet('ffmpegKitPackage', 'https').contains("-lts") ? 16 : 24
    targetSdkVersion 30
    versionCode 451
    versionName "4.5.1"
  }

  buildTypes {
    release {
      minifyEnabled false
    }
  }
  lintOptions {
    disable 'GradleCompatible'
  }
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }

  rootProject.ext.ffmpegKitPackage = "video" // Added this line here 

}


  


  Error :

  I have tried ./gradlew clean but problem is still there.
How to fix this error ?
