Trim Audio Flutter ( ffmpeg_kit_flutter Package) Not Working

Audio Trim is not working

Flutter Version : 3.0.2 Dart : 2.17.3

Package used : ffmpeg_kit_flutter: ^4.5.1

Input file path : "/data/user/0/com.goonetech.v1.gofinal/cache/file_picker/sample-15s.mp3"

Output file path : "/data/user/0/com.goonetech.v1.gofinal/app_flutter/output.mp3"


double start=2, 
double end=5;

String path="/data/user/0/com.goonetech.v1.gofinal/cache/file_picker/sample-15s.mp3"


    static Future<String> cutAudio(String path, double start, double end) async {
    final Directory dir = await getApplicationDocumentsDirectory();
    final outPath = "${dir.path}/output.mp3";
    double start = 1;
    double end = 5;

    try 
{
      await File(outPath).delete();
    } catch (e) {
      print("Delete Error");
    }

    var cmd =
        "-y -i \"$path\" -vn -ss $start -to $end -ar 16k -ac 2 -b:a 96k -acodec libmp3lame $outPath";

    FFmpegKit.executeAsync(cmd, (session) async {
      final returnCode = await session.getReturnCode();
      print("returnCode $returnCode");
    });

    return outPath;
  }

The output is : returnCode 1

The output path does not have the file (File not found exception)

You have to enable lame for this to work. By default FFmpegKit comes with html package. To use lame you have to use audio library

In android/build.gradle add the ext

ext {
      flutterFFmpegPackage  = "audio"
  }

Check this for more info https://pub.dev/documentation/flutter_ffmpeg/latest/
