I'm trying to find the midpoint of a video, in other words divide the total length by 2
. ffmpeg
gives time in format HOURS:MM:SS.MICROSECONDS
, so ignoring microseconds, how could I get the half way point? I've tried dividing each number (hours/minutes/seconds
) by 2
but this fails in the case of 0:01:00
, for example.
如何将持续时间分成两半

This can be much simpler (and maybe even faster) if we use the parsing and formatting logic provided by the
time
package.func getDividedTime(times string, n int) (string, error) { t, err := time.Parse("15:04:05.000000", times) if err != nil { return "", err } d := t.Sub(time.Time{}) / time.Duration(n) return time.Time{}.Add(d).Format("15:04:05"), nil }
Try it on the Go Playground. The weakness of this solution is that it "rejects" inputs having
hours > 23
