  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    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. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

    Here is the screenshot of the generated files.

    This is my Android.mk file.

    LOCAL_PATH := $(call my-dir)
    
include $(CLEAR_VARS)
    
LOCAL_C_INCLUDES := $(ANDROID_NDK)/sources/ffmpeg-3.3
    
LOCAL_CFLAGS := -Os -fpic -marm -march=armv7-a -mfloat-abi=softfp -mfpu=neon
    
LOCAL_MODULE := MyFFmpeg
    
LOCAL_SRC_FILES := arm/videoKit.c arm/ffmpeg.c arm/ffmpeg_filter.c arm/ffmpeg_opt.c arm/cmdutils.c
    
LOCAL_STATIC_LIBRARIES := libavdevice libavformat libavfilter libavcodec libavutil libswresample libswscale

  • FFMPEG image to video showing blank video

    18 avril 2017, par Ravi Rupareliya

    Here is my command to create a video from multiple images.

    File f = new File(Environment.getExternalStorageDirectory() + "/abc.mp4");
    

    
try {
    
    f.createNewFile();
    
    ffmpeg.execute(new String[]{"-y","-r","1/5","-i","" + "/" + "image%01d.jpg","-pix_fmt","yuv420p","-c:v","libx264","-crf","23","-s","640x480",f.getPath()}, listener);
    
} catch (Exception e) {
    
    e.printStackTrace();
    
}

    I have multiple images available at with having names like image1.jpg, image2.jpg etc etc.

    It is creating video file with some 100-200 KB but it showing blank images in VLC player.

    When i try to run it with Windows Media Player, it only runs if it is in repeat mode from player, otherwise it is not playing.

    Output in onSuccess()

If you think configure made a mistake, make sure you are using the latest
    
version from Git.  If the latest version fails, report the problem to the
    
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
    
Include the log file "config.log" produced by configure as this will help
    
solve the problem.
