ffmpeg difference between time and rtime, utime - Stack Overflow

programmeradmin9浏览0评论

When I execute a command with "-benchmark" I can get some information like rtime, utime, stime which are real time, user time and system time respectively. But I can't understand what are they exactly? Because as I know, the real time is the wall clock which means the time that the whole process needs.

And there is another time at the end of the command.

Like below:

What is the difference between them? time: 00:00:00.16 rtime: 0.197s

As I understand,

rtime: It's the actual time taken to process the media utime: It shows the time spent in user-mode. It's cpu processing time.

For time, I have questions. What's the total length of the media? What time is showing after ffmpeg completed?

Here is the source code of it: https://github/ffmpeg/ffmpeg/blob/master/fftools/ffmpeg.c#L998
