按長度排序視頻，需要效率，如果可能的話可靠性

Question

這使用mediainfo來提取視頻屬性，然後檢查軌道長度並將視頻相應地排序爲長或短目錄。

mediainfo.exe %1 >%temp%\vdata

正如您所看到的那樣效率很低。這可以減少到幾行？也作爲一個側面提示，這個軌道長度檢查不是很可靠，因爲有時視頻集成了錯誤的軌道（通常是字幕），這意味着不正確的長度的額外軌道將決定視頻應該去哪裏。

這是mediainfo如何將數據輸出到vdata文件的方式。視頻軌道的持續時間應始終在同線7

Answer 1

這將有可能通過使用串他們的數學等價物代替「H」，「分鐘」，和「s」到h min s公約轉換爲整數替換，然後用set /a將整個數學計算成幾秒鐘。一旦你有這個秒整數，除以60分鐘。

另外，不需要將mediainfo的輸出轉儲到文本文件。只需使用for /f即可獲取。

@echo off & setlocal 

set "video=%~f1" 

rem // Change "args" to whatever arguments mediainfo requires. I don't know its syntax. 
for /f "tokens=2*" %%I in (
    'mediainfo args "%video%" ^| findstr /irc:"Duration.*[0-9] [hms]"' 
) do if not defined duration set "duration=%%J" 

set "duration=%duration: h=*3600%" 
set "duration=%duration: min=*60%" 
set "duration=%duration: s=%" 
set /a "minutes=%duration: =+%/60" 

if %minutes% leq 25 (
    move "%video%" short\ 
) else (
    move "%video%" long\ 
) 

...或相似。

雖然有一個更好的工具來抓取視頻文件的持續時間。 ffprobe（FFmpeg的軟件包的一部分）將讓你獲得視頻的全球持續時間seconds.microseconds使用下面的命令：

ffprobe -v quiet -show_entries "format=duration" -of csv "filename.mkv" 

輸出類似於此：

格式，5028.080000

與上面的mediainfo示例一樣，使用for /f循環捕獲ffprobe的輸出。

@echo off & setlocal 

set "video=%~f1" 

for /f "tokens=2 delims=,." %%I in (
    'ffprobe -v quiet -show_entries "format=duration" -of csv "%video%"` 
) do set /a "minutes = %%~I/60" 

if %minutes% leq 25 (
    move "%video%" short\ 
) else (
    move "%video%" long\ 
)
