• Crash while using ffmpeg4android using Galaxy s6 edge device

  21 juillet 2016, par Amira Elsayed Ismail

  I am using ffmpeg4android_lib to compress video in my android application, it is working in almost all testing devices but it does not work in Galaxy s6 edge and Galaxy s7 edge.

  my code as following :

  String inputFile = FileManager.getInstance().getRealPathFromVideoUri(context, video);
  
  Log.i("INPUT FILE PATH", inputFile);
  
  
  
  LoadJNI vk = new LoadJNI();
  
  try {
  
          String workFolder = context.getApplicationContext().getFilesDir().getAbsolutePath();
  
          String outputFile = FileManager.getInstance().getFileFullName(ForSaleConstants.VIDEO_FOLDER,
  
          String.format(ForSaleConstants.VIDEO_NAME_FILE_FORMAT,      ForSaleConstants.VIDEO_NAME_FILE_NAME_PREFIX, System.currentTimeMillis()));
  
  
  
          String complexCommand[] = {
  
              "ffmpeg", "-y"
  
              , "-i", inputFile
  
              , "-strict", "experimental"
  
              , "-s", "320x240"
  
              , "-r", "25"
  
              , "-aspect", "4:3"
  
              , "-ab", "48000"
  
              , "-ac", "2"
  
              , "-vcodec", "mpeg4"
  
              , "-movflags", "+faststart"
  
              , "-ar", "22050"
  
              , "-b", "2097k"
  
              , outputFile};
  
              vk.run(complexCommand, workFolder, context.getApplicationContext());
  
              Log.i("OUTPUT FILE PATH", outputFile);
  
              return outputFile;
  
      } catch (Throwable e) {
  
          ForSaleServerManager.getInstance().logAndroidError("Couldn't compress video file");
  
          return null;
  
      }

  The crash as following :

  nativeLibraryDirectories=[/data/app/com.forsale.forsale-1/lib/arm64, /data/app/com.forsale.forsale-1/base.apk!/lib/arm64-v8a, /vendor/lib64, /system/lib64]]] couldn't find "libloader-jni.so"

• interrupting the merge video process without any explicit errors

  14 décembre 2018, par torin.dmitry

  I just trying to concatenate several videos (30 or more) in one sequence using attached commands :

  Commands :
  ffmpeg_concat_videos_cmds.txt

  Error :
  ffmpeg_error.txt

  library : bravobit or WritingMinds (result the same)

  device : Xiaomi Redmi Note 2 android 5.0.1, SoC mediatek (Actually, result the same on other devices)

  I might have thought this something wrong with my input files, but this is floating issue, and happens in 50% cases +-

  observation 1 : if I reduce amount of input files, let’s say, to 27-28, this issue is disappear. By the way, it does not depend on which files I delete, just a smaller amount. If I increase amount of files - issue will remain the same behavior. (Can a ffmpeg have any restrictions on the number of concatenating videos ?)

  observation 2 : The merge process is interrupted in a random place. And ffmpeg finishing with error (in attached file)

  I don’t understand why it’s happens absolutely random... Options doesn’t changing every iteration, input data always the same.

  regarding attached files, as for me, everything looks fine, except last part :
