c# - 使用 C# 和 MediaInfo 如何检测 HDR 格式

Question

我正在使用MediaInfo Nuget Wrapper分析一堆文件

在我可以看到的文件上使用 MediaInfo Actual

Video 
ID : 1 
Format : HEVC 
Format/Info : High Efficiency Video Coding 
Format profile : Main <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="82b3b2c2ceb7acb3" rel="noreferrer noopener nofollow">[email protected]</a>@Main 
HDR format : Dolby Vision, Version 1.0, dvhe.05.09, BL+RPU 
Codec ID : dvhe 
Codec ID/Info : High Efficiency Video Coding with Dolby Vision 

这也可以通过 Console.WriteLine(mw1.Inform());

看到

但是我无法从下面的代码中得到它
我尝试过 HDR 格式、HDRformat 和其他拼写，但总是返回“”

鉴于每个文件都会不同，是否有一种更动态的方法来执行此操作，而不是对每个属性进行硬编码？

代码仍处于测试阶段

Answer 1

I've tried HDR format, HDRformat and other speling but always returns ""

HDR_Format

提示:要了解要使用的键，请使用带有“--Language=raw”的 MediaInfo 命令行或带有 XML 输出的图形界面。
