如何使用mediainfo以秒或其他格式查找视频文件的持续时间？(How to find duration of a video file using mediainfo in seconds or other formats?)

如何以毫秒为单位查找视频文件的持续时间，即以确定性方式查找整数。 我已经使用ffprobe来获得持续时间，但它不给所有文件格式的持续时间。

How can I find duration of a video file in miliseconds i.e. in integer in deterministic way. I have used ffprobe to get the duration but it doesn't give duration for all file formats.

最满意答案

使用以下命令：

i）获得视频流的持续时间：

$ mediainfo --Inform="Video;%Duration%" [inputfile]

ii）获取媒体文件的持续时间：

$ mediainfo --Inform="General;%Duration%" [inputfile]

iii）仅获取音频流的持续时间：

$ mediainfo --Inform="Audio;%Duration%" [inputfile]

iv）获取多个参数的值：

$ mediainfo --Inform="Video;%Width%,%Height%,%BitRate%,%FrameRate%" [inputfile]

输出将是这样的：

1280,720,3000000,30.0

Use the following commands:

i) To get the duration of video stream:

$ mediainfo --Inform="Video;%Duration%" [inputfile]

ii) To get the duration of the media file:

$ mediainfo --Inform="General;%Duration%" [inputfile]

iii) To get the duration of audio stream only:

$ mediainfo --Inform="Audio;%Duration%" [inputfile]

iv) To get values of more than one parameter:

$ mediainfo --Inform="Video;%Width%,%Height%,%BitRate%,%FrameRate%" [inputfile]

Output would be something like this:

1280,720,3000000,30.0
