I am not experienced with ffmpeg. So I'm sorry if I'm asking the wrong question in the wrong place. i am trying to make a video compressor, i add the dependency exactly like : ffmpeg_kit_flutter_full_gpl: ^4.5.1 and The code I wrote is like:

compress(path) {
  FFmpegKit.executeAsync("-i $path -c:a copy -c:v libx264 -s 848x360 output.mp4", (session) async {
  final returnCode = await session.getReturnCode();
 if (ReturnCode.isSuccess(returnCode)){

     print("işlem başarılı");
  // SUCCESS

 } else if (ReturnCode.isCancel(returnCode)) {

  print("iptal edildi");
 // CANCEL

 } else {

   print("hata oluştu");
   print(await session.getFailStackTrace());
   // ERROR

 }
});

}

and im calling this method like:

asset.originFile.then((fle) {
       var path = fle!.path;
       compress(path);
       }
);

it always returns error condition for some reason. and session.getFailStackTrace() is null.

My first question is what do you think is wrong here?

And secondly how can I detect what the error is in such cases?

thanks in advance :)
