  • 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.

  • Batch file to perform multiple conversions in a row

    16 septembre 2020, par ben158

    I'm trying to write a batch file that can be launched from Handbrake GUI with the "send file to" feature, that will split an MKV into chapters with MKVmerge, then convert all those new files into mp4s with ffmpeg. Handbrake passes only one argument into the batch file, the full file path of the output (surrounded by quotes). I'm very new to batch scripting and am having difficulty getting it all to work together — all the individual parts work just fine when absolute paths are given. Here's the content of the .bat file :

    


    START /WAIT "C:\Program Files\MKVToolNix\mkvmerge.exe -o output.mkv --split chapters:all %1"
for %%i in (*.mkv) do C:\ffmpeg\bin\ffmpeg.exe -i "%%i" -loop 1 -i "%%~dpi"\folder.jpg -map 1:v -map 0:a -c:a ac3 -b:a 640K -pix_fmt yuv420p -c:v libx264 -shortest -fflags +shortest -max_interleave_delta 100M "%%~ni.mp4"


    


    Any glaring mistakes I'm making ? I've been at this for hours reading SO threads and documentation, and can't figure it out for the life of me. Any help is appreciated, thanks in advance.

    


  • Create Video Thumbnail of All Files in a Directory via FFmpeg and PHP

    2 février 2012, par Hashid Hameed

    I have searched all over the Google and StackOverFlow, but still did not find a solution for this.

    I want to generate video thumbnail of all mp4 video files in a directory and name the thumbnails as "filename.mp4".jpg

    I have ffmpeg and ffmpeg-php installed on my server. I also succeeded in creating thumbnails of one file at a time.

    So this is the situation, I have a directory named uploads which has lots of mp4 videos.
    Now, when I run the script, thumbnail of size 100x100 shoud be created automatically and placed in another folder "skrin". Eg : xxx.mp4 should have xxx.mp4.jpg has the thumb name.

    IMPORTANT : My filenames have spaces, single quotes, brackets etc in their file names. So the script should be able to handle this.

    Could some one help me ? I use the following shell command in php using exec to generate thumb of an individual video.

    exec("/usr/local/bin/ffmpeg -itsoffset -105 -i 'xxx haha.mp4' -vcodec mjpeg -vframes 1 -an -f rawvideo -s 100x100 'xxx haha.mp4.jpg'");

  • How to create mpeg-dash mpd file with multiple periods ?

    14 septembre 2022, par Nimish Agrawal

    I wanted to join multiple mp4 files to create a mpd file. I wanted to have each of the individual mp4 files to be in different periods.

    


    I tried to do that using ffmpeg

    


    ffmpeg -i INPUT_FILE1.mp4 INPUT_FILE2.mp4 ...options... -f dash output.mpd


    


    But it is only considering first mpd file. Is it possible to do this using ffmpeg or any other tool ?

    


    ffmpeg -y -re -i big_buck_bunny_720p_1mb.mp4  -c:v libx264 -x264opts "keyint=24:min-keyint=24:no-scenecut" -r 24  -c:a aac -b:a 128k  -bf 1 -b_strategy 0 -sc_threshold 0 -pix_fmt yuv420p  -map 0:v:0 -map 0:a:0 -map 0:v:0 -map 0:a:0 -map 0:v:0 -map 0:a:0  -b:v:0 250k  -filter:v:0 "scale=-2:240" -profile:v:0 baseline  -b:v:1 750k  -filter:v:1 "scale=-2:480" -profile:v:1 main  -b:v:2 1500k -filter:v:2 "scale=-2:720" -profile:v:2 high  -use_timeline 1 -use_template 1 -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a"  -f dash movie-dash\movie.mpd
