How to find duration of a video file using mediainfo in seconds or other formats?

Question

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 fi

Answer 1

As offered by iota to use mediainfo --Inform="Video;%Duration%" [inputfile], possible but returns weird results.

For example, for video with duration 31s 565ms the output of given command would be:

31565

It wasn't suitable for me and I came up to the following solution:

mediainfo --Inform="Video;%Duration/String3%" inputExample.webm

Returned value is:

00:00:31.565

After all, you could just format returned value with, let's say PHP, to convert it to seconds, e.g.:

$parsed = date_parse( '00:00:31.565' );
echo $parsed['hour'] * 3600 + $parsed['minute'] * 60 + $parsed['second'];
