How to force ffmpeg to show progress

[cvdevol]

Is there an option to force ffmpeg to show progress when converting the audio of a youtube video after downloading?

Currently manually handled, download raw, then use ffmpeg directly and manage progress.
Made use in combination with FFMpegCore NuGet.

`await Utils.DownloadFFmpeg();
await Utils.DownloadFFprobe();

    public static async Task<bool> ConvertWebmToMp4(string webmFilePath, string outputMp4Path, string thumbnailPath, IProgress<ProgressReport> progress = null, int itemIndex = 1, int totalItems = 1, string title = "", string duration = "")
    {
        var analysis = await FFProbe.AnalyseAsync(webmFilePath);
        bool hasThumbnail = File.Exists(thumbnailPath);

        float baseBatchPercentage = ((float)(itemIndex - 1) / totalItems) * 100f;

        var success = await FFMpegArguments
            .FromFileInput(webmFilePath)
            .AddFileInput(hasThumbnail ? new FileInfo(thumbnailPath) : null)
            .OutputToFile(outputMp4Path, true, options =>
            {
                if (hasThumbnail)
                    options.WithCustomArgument("-map 0:v:0 -map 0:a:0 -map 1:0 -c:v copy -c:a aac -disposition:v:1 attached_pic");
                else
                    options.WithCustomArgument("-map 0:v:0 -map 0:a:0 -c:v copy -c:a aac");
            })
            .NotifyOnProgress(percentage =>
            {
                float itemPercent = Math.Clamp((float)percentage, 0f, 100f);

                progress?.Report(new ProgressReport
                {
                    Stage = DownloadStage.Converting,
                    ItemPercentage = itemPercent,
                    TotalPercentage = baseBatchPercentage,
                    CurrentItemIndex = itemIndex,
                    TotalItems = totalItems,
                    StatusMessage = $"Converting video [{itemIndex}/{totalItems}] '{title}' ({duration}): {itemPercent:F1}%"
                });
            }, analysis.Duration)
            .ProcessAsynchronously();

        if (success)
        {
            progress?.Report(new ProgressReport
            {
                Stage = DownloadStage.Converting,
                ItemPercentage = 100f,
                TotalPercentage = baseBatchPercentage,
                CurrentItemIndex = itemIndex,
                TotalItems = totalItems,
                StatusMessage = $"Converting video [{itemIndex}/{totalItems}] '{title}' ({duration}): 100.0%"
            });
        }

        return success;
    }
