  • ffmpeg difference between time and rtime, utime

    15 janvier, par nojob

    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 :

    


    enter image description here

    


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

    


  • How to compare the difference between 2 videos color in ffmpeg ?

    3 décembre 2014, par nico_lab

    I have read How to compare/show the difference between 2 videos in ffmpeg ? , but "blend=all_mode=difference" is green.
    How do I get more colorful diffrence using blend filter ?

    sample command is

    ffplay -f lavfi "movie=left.mp4,split[a1][a2]; movie=right.mp4,split[b1][b2]; [a1][b1]blend=all_mode=difference[blend];[a2]pad=2*iw:2*ih[left];[left][b2]overlay=w[tmp];[tmp][blend]overlay=0:h"

    using "hue=s=0", color is chenge monochrome.

    ffplay -f lavfi "movie=left.mp4,split[a1][a2]; movie=right.mp4,split[b1][b2]; [a1][b1]blend=all_mode=difference,hue=s=0[blend];[a2]pad=2*iw:2*ih[left];[left][b2]overlay=w[tmp];[tmp][blend]overlay=0:h"

  • what difference between Opencv capture and use ffmpeg and v4l2 to catch camera image [closed]

    18 janvier 2024, par JXJUT

    I'm doing a project which uses a usb camera on Raspberry PI to do the vision process. I get a demo from my coworker. They use v4l2 and ffmpeg to catch the image and then process it in Opencv instead of directly using Opencv capture to catch the image. I wonder if there is a difference between the two methods.
