    Pour gérer l’ajout et la suppression de fonctionnalités supplémentaires (ou plugins), MediaSPIP utilise à partir de la version 0.2 SVP.
    SVP permet l’activation facile de plugins depuis l’espace de configuration de MediaSPIP.
    Pour y accéder, il suffit de se rendre dans l’espace de configuration puis de se rendre sur la page "Gestion des plugins".

  • MediaSPIP : Modification des droits de création d’objets et de publication définitive

    11 novembre 2010, par

    Par défaut, MediaSPIP permet de créer 5 types d’objets.
    Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.
    Ces droits sont ainsi bloqués pour plusieurs raisons : parce que le fait d’autoriser à publier doit être la volonté du webmestre pas de l’ensemble de la plateforme et donc ne pas être un choix par défaut ; parce qu’avoir un compte peut servir à autre choses également, (...)

  • Displaying the current frame of a video after skipping using drawtext/start_number not evaluation any variables

    25 mars 2023, par DJ Quardaboff

    I would like to display the current frame number on a video while playing it with ffplay. I have already seen this solution, but when I seek to any part of the video, the counter resets. There's a variable, start_number, which the ffplay documentation says is The starting frame number for the n/frame_num variable. The default value is "0". It seems that n is set to that when starting the video or seeking between I-frames. I thought setting this variable to %{floor(t*60)} would solve my problem, but after running this :

    



    ffplay -i "video.mp4" -vf drawtext="fontsize=30:box=1:boxcolor=white:fontcolor=black:fontfile=/Windows/Fonts/arial.ttf:start_number=floor(t*60):text=%{n}"


    



    I got the following console output :

    In fact, any variable in start_number's assignment invokes this error. I don't know if I have the correct syntax, but does this mean it doesn't evaluate expressions ? Or maybe it doesn't accept variables for some reason ?

    



    After that downer I tried just setting the text to %{t}, which played the video, but repeatedly gave this error and had no text in the top left corner :

    



    [Parsed_drawtext_0 @ 0000000003e54ea0] %{t} is not known 0B f=0/0


    



    So does the current time variable just not work in drawtext ?
    
Is there another way to write the current frame on the video or even on the console window ?

    



    Using Windows 10 Enterprise and the latest build of ffplay for windows at this time.

  • can i speedup text watermarking on ffmpeg ?

    3 juin 2020, par Easy Tricks For Android

    This command i used ffmpeg -i "1.mp4" -vf "drawtext=text='watermak_name':x=w-tw-50:y=h-th-50:fontfile=/Windows/fonts/calibri.ttf:fontsize=20:fontcolor=white:shadowcolor=black:shadowx=2:shadowy=2" "output.mp4". watermark is working with this command, but it takes more time up-to 3 hours +
