    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

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

  • Put audio and video tracks all together

    24 février 2014, par Albert

    I have one video track (xvid) and two audio tracks (ac3) in three different files, and I want to put them together. I succeeded, but there is a problem. This is the command I use :

    ffmpeg -i video.avi -i audio_es.ac3 -i audio_en.ac3 -map 0:0 -map 1:0 -map 2:0 -vcodec copy -acodec copy -acodec copy  video2.avi -newaudio

    And this is the output

    As you see in output stream, it doesn't convert any input file except second audio stream into mp2 (64kbps), while input file is AC3 (320kbps). I don't know how to tell ffmpeg to not convert any file. Just put them together as they are.

    Can anybody help me ?

  • ffmpeg mp4 file is not valid

    10 mars 2014, par Flash Thunder

    I was looking for answer on Internet but, didn't find any...

    Got 3 movies, all made by ffmpeg from separate frames in png files with command :

    ffmpeg -r 100 -qscale 2 -i input/%06d.png output/movie.mp4

    Two of them work perfectly... Windows Media Player and all others see it as correct format..., but one of them not. Only VLC can play it, all other players say that it is unknown format. It probably has something to do with size of images. Would like to know what are the criteria... what size should it have... why one is working and other is not...

    Sizes are :

    1. 1600x1570 - works fine
    2. 1880x616 - works fine
    3. 1891x725 - doesn't work...

    This is really weird, because fullhd has width of 1920, so all above are lower...

    All images are made by PHP with gdlib, all saved the same method... it is not the problem of count, because no matter if I get only first 100 frames, or whole movie, it still doesn't work... only the last one. Any ideas what could possibly be wrong ?

    Complete FFMPEG output (for 200 frames) :
