I’ve been using GPT and publications from Medium to help with my how I’m supposed to use the FFmpeg kit for Flutter but they have been no help. Perhaps I need clarification on what the tool is supposed to do because links like these below have not been of any help and are very outdated:

This is the code i’ve been trying to run to convert a video file before I upload to Firestore Database.

Future<Uint8List?> convertToH264(Uint8List bytes) async {
  try {
    final filename = const Uuid().v4();
    final tempDir = await getTemporaryDirectory();
    final tempVideoFile = File('${tempDir.path}/$filename.mp4');
    await tempVideoFile.writeAsBytes(bytes);
    final outputPath = '${tempDir.path}/$filename-aac.mp4';

    await FFmpegKit.execute(
      '-i ${tempVideoFile.path} -c:v libx264 -c:a aac $outputPath',
    );
    return await File(outputPath).readAsBytes();
  } catch (e) {
    rethrow;
  }
}
