Question

我想使用元数据提取器从360张照片中读取GPano XMP数据。我正在使用Ricoh Theta S的照片作为我的测试图像，我在XmpDirectory中收到错误。

“处理XMP数据时出错：不支持的编码”

我的代码很基本，

        var dirs = ImageMetadataReader.ReadMetadata(filePath);
        var xmpDir = dirs.OfType<XmpDirectory>().FirstOrDefault();
        if (xmpDir?.XmpMeta != null)
        {
            foreach (var property in xmpDir.XmpMeta.Properties)
                Console.WriteLine($"Path={property.Path} Namespace={property.Namespace} Value={property.Value}");
        }

但是XmpMeta总是为空。如果我在XmpDirectory中使用调试器查看，则错误在_errorsList中。

我知道图像有我要访问的XMP数据，如果我在记事本++中打开图像字节，我可以用明文定位数据。

我正在使用nuget的Metadata-Extractor 2.0.0。
