    Command and console output :

Codec AVOption vbr (VBR mode (1-5)) specified for output file #0 (output.mp4) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.

  • file sequence (%d) not working when increased to 3 digits FFMPEG

    13 avril 2018, par Junaid Farooq

    I have this kind of image sequence in my folder.

    113.jpg  119.jpg  125.jpg  131.jpg  164.jpg  17.jpg   175.jpg  180.jpg  23.jpg  29.jpg  35.jpg  68.jpg  74.jpg  80.jpg  CURRENT
    
114.jpg  120.jpg  126.jpg  132.jpg  165.jpg  170.jpg  176.jpg  181.jpg  24.jpg  30.jpg  36.jpg  69.jpg  75.jpg  81.jpg  list.txt
    
115.jpg  121.jpg  127.jpg  133.jpg  166.jpg  171.jpg  177.jpg  19.jpg   25.jpg  31.jpg  37.jpg  70.jpg  76.jpg  82.jpg  testingplease.mp4
    
116.jpg  122.jpg  128.jpg  161.jpg  167.jpg  172.jpg  178.jpg  20.jpg   26.jpg  32.jpg  65.jpg  71.jpg  77.jpg  83.jpg
    
117.jpg  123.jpg  129.jpg  162.jpg  168.jpg  173.jpg  179.jpg  21.jpg   27.jpg  33.jpg  66.jpg  72.jpg  78.jpg  84.jpg
    
118.jpg  124.jpg  130.jpg  163.jpg  169.jpg  174.jpg  18.jpg   22.jpg   28.jpg  34.jpg  67.jpg  73.jpg  79.jpg  85.jpg

    When I run this command to create a video file

    ffmpeg -r 6 -i /storage/taked-qzaxs/extract/1239/%d.jpg -c:v h264_nvenc -r 6 -preset slow -bufsize 1000k -pix_fmt yuv420p -y /storage/taked-qzaxs/extract/1239/testingplease.mp4

    It throws me such error as

    [image2 @ 0x55ad2ff3d460] Could find no file with path '/storage/taked-qzaxs/extract/1239/%d.jpg' and index in the range 0-4
    
/storage/taked-qzaxs/extract/1239/%d.jpg: No such file or directory

    Whereas the same command works fine when there are only 10 or 15 images, and image number is within 2 digits range. I don’t know what is wrong with this command. I am using %d, which means it should take all natural numbers in sort form.

  • FFMPEG cut out group of frames

    20 juin 2019, par Virgosh

    I’m looking for a command to cut out exact frames from a video.

    I know that I can do this by slicing the video in two and then concat,
    but I’m looking for a sigle command to achive the same result,
    something like :

    ffmpeg -i video.mov -cutframe 1239 video_cut.mov

    or something like

    ffmpeg -ss 2348 -i video.mov -tt 2349 video_cut.mov
