        var sb = new StringBuilder();
        for (var i = 0; i < sampleMetadataCount; ++i)
        {
            if (metadataInfo != null &amp;&amp; i < metadataInfo.Length)
                sb.Append(metadataInfo[i].name);
            else
                sb.Append(i);
            sb.Append(": ");
            sb.Append(frameDataView.GetItemMergedSamplesMetadata(itemId, mergedSampleIndex, i));
