    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement.

  • ffmpeg - read imagefolder and add Watermark

    31 juillet 2015, par dazzafact

    Rightnow iam using successful this command to read an imagefolder and create a videofile

    ffmpeg -f image2 -pattern_type glob -i 'image2/in*.png' 
    
-vf fps=25/1 -s 720x576 -b 1000k out.flv -timeout 3

    But i also wanna add a Watermark to the Video, but it will not work with this :

    ffmpeg -f image2 -pattern_type glob -i 'image2/in*.png' 
    
-vf fps=25/1 -s 720x576 -i logo_fff.png -filter_complex 
    
"overlay=10:main_h-overlay_h-10"-b 1000k out.flv

    The command to create the watermark separtly 100% works with a Videofile but not with an imagefolder ?

     ffmpeg -i in.flv -s 720x576 -i logo_fff.png -b 1000k 
    
-filter_complex "overlay=10:main_h-overlay_h-10" out.flv

    Where is the mistake ?

  • how to speed up video and add watermark using ffmpeg

    30 octobre 2017, par 1234567

    How can we speed up video and add watermark using ffmpeg

    for speed up video we have this command

    ffmpeg -i input.mp4 -filter_complex "[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]" -map "[v]" -map "[a]" output.mp4

    for water mark we use

    "-y", "-i", j, "-i", image1, "-i", image2, "-i", image3, "-filter_complex",
    
               "[0:v][1:v] overlay=0:0:enable='between(t,1,2)'[tmp];" +
    
                       "[tmp][2:v] overlay=0:0:enable='between(t,5,7)'[tmp];"+
    
                       "[tmp][3:v] overlay=0:0:enable='between(t,9,11)'",
    
                "-c:v","libx264",  "-preset", "ultrafast", out;

    how can we merge bot commands I have various commands
    like this

        ""-y", "-i", j, "-i", image2, "-i", image2, "-i", image2, "-filter_complex",
    
     "[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]" +
    
             "[1:v] overlay=0:0:enable='between(t,1,2)'[tmp];" +
    
                  "[tmp][2:v] overlay=0:0:enable='between(t,5,7)'[tmp];"+
    
                    "[tmp][3:v] overlay=0:0:enable='between(t,9,11)'",
    
            "-map", "[v]", "-map", "[a]", "-b:v", "2097k", "-r", "60", "-vcodec", "mpeg4",
    
              "-preset", "ultrafast", out"
