• Difference between .so file and java library in ffmpeg

  1er septembre 2020, par yejafot

  Is there any difference between using ffmpeg with .so file(ndk,.cpp) or simply by using ffmpeg library(example : com.github.hiteshsondhi88.libffmeg). I see my collegues apps sell 10rs by using these libraries vs with app on cpp function call sells 1000rs+ ?

  


  Implementation with java library :

  


  FFmpeg ffmpeg = FFmpeg.getInstance(context);
try {
  // to execute "ffmpeg -version" command you just need to pass "-version"
  ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {

    @Override
    public void onStart() {}

    @Override
    public void onProgress(String message) {}

    @Override
    public void onFailure(String message) {}

    @Override
    public void onSuccess(String message) {}

    @Override
    public void onFinish() {}
  });
} catch (FFmpegCommandAlreadyRunningException e) {
  // Handle if FFmpeg is already running
}


  


• In FFmpeg, can -filter_complex do everything that -filter can ? (i.e., is it a direct replacement)

  1er avril 2020, par Robert Salesas

  This may seem like a strange question but... is it possible to do everything -filter can do using only -filter_complex filters ? That is, is there anything that -filter can do, that is not possible with -filter_complex ?
