  • ffmpeg conversion of jpg to mp4 fails due to to jpg frames change

    14 janvier 2019, par Sebastien Damaye

    I’m trying to compile a set of jpg (camera screenshots taken every 5 seconds) to a mp4. The ffmpeg command works fine but the resulting mp4 is missing some images. I noticed that the "holes" are created when the jpg "frames" is changing from 1 to 3 in the jpg sequence (see below result of file that shows frames 1 for the 1st jpg and frames 3 for the 2nd one) :

    $ file 20190110060113.jpg
    20190110060113.jpg: JPEG image data, JFIF standard 1.01, aspect ratio, density 1x1, segment length 16, baseline, precision 8, 1280x720, frames 1

    $ file 20190110060119.jpg
    20190110060119.jpg: JPEG image data, JFIF standard 1.01, aspect ratio, density 1x1, segment length 16, baseline, precision 8, 1280x720, frames 3

    And with ffmpeg, it sows :

    ffmpeg -i 20190110060113.jpg -i 20190110060119.jpg

    At least one output file must be specified

    Below is the command I’m using to compile the mp4 from the jpg :

    ffmpeg -r 25 -f image2 -s 1280x720 -i /data/camipjpg/%*.jpg -vcodec libx264 -crf 25 -pix_fmt yuv420p /data/camipmgpg/20190110.mp4

    For the sake of curiosity, I investigated and noticed that the camera actually has 2 modes (day and night). Images taken during the night have frames 1 while images taken on the "day" mode have frames 3.

    Is there a way ffmpeg can handle that kind of jpg changes to combine these different types of jpg ?

    Here is the output :

  • Anomalie #3862 : .spip_logo

    22 novembre 2016, par J. Alberto ZAMBRANO

    bonjour,

    "est-ce un problème sur un squelettes-dist de SPIP ou bien un squelettes
    déjà modifié ? "
    Les deux mon capitaine :-)
    Je fais un site pour une amie, je prends spip et je fait quelques
    modifications (j’allège) à partir des squelettes-dist. L’entête de la dist
    me vas parfait, mais...
    Je fais une page "catalogue" (rubrique) pour afficher les articles, et je
    me lance dans une flexbox grids
    <http://codepen.io/raphaelgoetter/pen/mzKrh?editors=110> qui m’afficherait
    le titre et le logo de l’article. Juste modifier la classe dans le
    squelette de la rubrique et le tour est joué :

  • FFMPEG FFBROBE Get Frame Count On Powershell [duplicate]

    27 avril 2020, par ilham zacky

    I am new to FFmpeg, I have some audio and video files, I need to get the duration with frames, I need it in this format H:M:S:F - "00:00:00:00", I am using Powershell

    &#xA;&#xA;

    currently, my duration works, but instead of frames, it prints a decimal value.&#xA;note : in my output maximum number of frames should be 30

    &#xA;&#xA;

    This is my code

    &#xA;&#xA;

    $audioId = "$id.m4a"&#xA;$videoId = "$id.mp4"&#xA;&#xA;$duration1 = if ((ffprobe -i $audioId 2>&amp;1 | Out-String) -match &#x27;Duration:\s&#x2B;([\d:"."]&#x2B;)&#x27;) { $matches[1] };&#xA;&#xA;$duration = if ((ffmpeg -i $videoId 2>&amp;1 | Out-String) -match &#x27;Duration:\s&#x2B;([\d:"."]&#x2B;)&#x27;) { $matches[1] };&#xA;&#xA;$newduration1 = ("$duration1").Replace(".",":")&#xA;$newduration = ("$duration").Replace(".",":")&#xA;&#xA;echo $duration1 &#xA;echo $duration&#xA;&#xA;

    &#xA;&#xA;

    my output be like

    &#xA;&#xA;

    00:00:03.48&#xA;00:00:03.46&#xA;&#xA;

    &#xA;
