    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • ffmpeg : How to split into smaller segments & repeat last frames ?

    25 juillet 2021, par Mehmed

    I want to split the input into smaller mpeg2video mxf segments ,but I have to copy the last minutes of each segment to the first of next segment , like this :

    


    enter image description here

    


    I can split it using Segment Muxer & -segment_time 00:00:10 and know about repeat frames using loop filter , but have no any idea how combine Segment
and loop filter to repeat/copy last minutes of each segment to the next segment while splitting.

    


    I tried the following command with no success :

    


    ffmpeg -i input -vcodec mpeg2video -vf loop=loop=1:size=25:start=225 -f segment -segment_time 00:00:10 output


    


    Is it possible by a FFmpeg command ? How ?

    


  • split a video with overlap between segments

    7 mai 2023, par John Pankowicz

    I need to split a video into a sequence of segments like the following : (numbers are mm:ss) 00:00 to 03:05, 03:00 to 06:05, 06:00 to 09:05, etc. In other words, each segment will have 5 seconds of overlap with the following segment. The purpose of this is for a transcription program. Each 3 minute segment will be transcribed separately. The 5 seconds of overlap will help in stitching the transcribed text segments back together.

    



    Do I need to extract each 3 minute and 5 second segment separately ? For example, by doing the following :

    



    ffmpeg -ss 00:03:00 -i in.mp4 -t 00:06:05 -vcodec copy -acodec copy -y out.mp4


    



    Or is there a way to do all the segments in one pass ?
