Video quality is compromising after adding watermark please fix this issue

[dzab5]

this issue should have top priority, basically undercuts the whole point of the package

Since March No breakthrough yet on the video Quality issue?

I found a solution.

Created my own watermark class that extends watermark, and i modified the toCommand fuction by adding bitrate command. You can add your own commands. FFMEG documentation

class QualityWatermark extends Watermark {
  final String bitrate;

  QualityWatermark({
    required super.image,
    required super.watermarkAlignment,
    required super.watermarkSize,
    required this.bitrate,
  });

  @override
  Future<String> toCommand() async {
    final command = await super.toCommand();
    return "$command -b:v $bitrate";
  }
}

and use it at VideoWatermark class.

    VideoWatermark(
      sourceVideoPath: videoFile.path,
      watermark: QualityWatermark(
        image: WatermarkSource.file(watermarkFile.path),
        watermarkAlignment: WatermarkAlignment.topLeft,
        watermarkSize: WatermarkSize(
          size?.width ?? -1,
          size?.height ?? -1,
        ),
        bitrate: '1M',
      ),
      outputFormat: OutputFormat.mp4,
      onSave: (path) => completer.complete(path),
    );

I am lazy to create enum values for bitrate field. 😄

By this method, you can inject additional commands.
