  • 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.

  • ffmpeg how to crop and scale at the same time ?

    13 décembre 2018, par Mitchell Faas

    I’m trying to convert a video with black bars, to one without and if the source is 4k, I want the video to be converted to 1080p

    Now to do this, I’m using the following command :*

    ffmpeg -i input ... -filter:v "crop=..." -filter:V "scale=1920:-1" ouput

    But running this, I found that the end product still has said black bars and is 1920x1080 as opposed to the 1920x800 I’d expect.

    What gives, why does this not work ?

    * : Other settings have been left out for convenience.

  • Create a video with other videos at certain points

    7 mars 2020, par Antique Chariot

    I’ve never used ffmpeg before, and I need to do something quite complicated (in my opinion at least, this could be easy).

    Basically I need to have a black video but at certain points concatenate other videos.
    For example, at 0.00 a 3 second video, then black until 10.0 and then another video, etc etc

    The finished videos will consist of hundreds of videos and be anywhere from 1-5 minutes long.

    I’m working in Node.js, ideally using a wrapper would be best (I’m using fluent-ffmpeg currently but any will suffice), although raw commands are also an option.

    Any ideas are appreciated !

    Edit : also, say a 5 second video is at 0.00, and a 10 second video is at 1.00, I’d like it to overwrite the original 5 second video

  • How can i combine three ffmpeg command in python ?

    15 mai 2022, par Anuj Saxena

    I want to combine three ffmpeg commands on my video and I want single output. In the following code I give a video(footage) as input and I want to compress my video, add watermark and also display frame numbers on the video and after executing these commands it gives an output video. How can I combine these commands ?

    


    f'''ffmpeg -i {footage} -vcodec libx264 -acodec aac \ "drawtext=text='{hostname}\n {socket.gethostbyname(hostname)}\n {getpass.getuser()}':x=10:y=H-th-10:fontfile=KhmerOS.ttf:fontsize=50:fontcolor=black:shadowcolor=black:shadowx=2:shadowy=2 " \ "drawtext=fontfile=KhmerOS.ttf: text='%{{frame_num}}': start_number=1: x=(w-tw)/2: y=h-(2*lh): fontcolor=black: fontsize=50: box=1: boxcolor=white: boxborderw=5" -c:a copy {mov_path} '''
