无法从mediainfo CLI获取BitRate_Mode

Question

下面是我的bat文件：

@echo off
mediainfo --Inform=file://template.txt "in.mp4" >info.txt

以下是我的template.txt

General;File is: %FileName%\r\n 
Video;\r\nFormat: %Format%\r\nCodecID: %CodecID%\r\nResolution: %Width%x%Height%\r\nDAR: %DisplayAspectRatio/String% or %DisplayAspectRatio%\r\nPAR: %PixelAspectRatio%\r\nFrameMode: %FrameRate_Mode%\r\nVideoBitrateMode: %BitRate_Mode%\r\nScanType: %ScanType%

Audio;\r\nAudioCodec: %Format%\r\nAudioBitrateMode: %BitRate_Mode%

以下是输出(info.txt格式)

File is: in

Format: AVC
CodecID: avc1
Resolution: 1280x720
DAR: 16:9 or 1.778
PAR: 1.000
FrameMode: VFR
VideoBitrateMode: 
ScanType: Progressive
AudioCodec: AAC
AudioBitrateMode: VBR

无论我做什么，我都不能让MediaInfo为任何给定的文件提供BitRate_Mode？以下是mediainfo的命令行界面帮助文档：Help doc

我做了详尽的测试，我发现大多数时候mediainfo不会在视频轨道上返回%BitRate_Mode%，但它确实会返回%BitRate_Maximum%，如果你将它与%BitRate%进行比较，它是不同的，这是一个VBR视频，这是我的模板：

General;Name.........: %FileName%.%FileExtension%\r\nSize.........: %FileSize/String%\r\nDuration.....: %Duration/String3%\r\n
Video;Resolution...: %Width%x%Height%\r\nCodec........: %Codec/String% %Format_Profile%\r\nBitrate......: %BitRate/String%\r\nMax Bitrate..: %BitRate_Maximum/String%\r\nFramerate....: %FrameRate% fps\r\nAspect Ratio.: %DisplayAspectRatio/String%\r\n
Audio;Audio........: %Language/String% %BitRate/String% %BitRate_Mode% %Channel(s)% chnls %Codec/String%\r\n
Text;%Language/String%
Text_Begin;Subs.........: 
Text_Middle;, 
Text_End;.\r\n

它将报废如下所示：
