ffmpeg-使用 ffmpeg 从摄像头拍摄图像并存储

下面的文件很好地满足了我的大部分要求。但是，时间格式似乎不是我想要的。无论计算机上的时间设置如何，我都希望始终获取时间ISO8601（例如 20150930T012823Z）。该怎么做？

这是一个与地区无关的获取日期和时间的方法。

@echo off
for /F "usebackq tokens=1,2 delims==" %%i in (
  `wmic os get LocalDateTime /VALUE 2^>NUL`
) do if '.%%i.'=='.LocalDateTime.' set ldt=%%j

set ldt=%ldt:~0,4%-%ldt:~4,2%-%ldt:~6,2% %ldt:~8,2%:%ldt:~10,2%:%ldt:~12,6%
echo Local date is [%ldt%]

输出：

Local date is [2015-10-02 20:10:00.000]

只需根据需要编辑变量即可。您可以获得更多变化这里
