    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 (...)

  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Creating TS file from MP4 file - Differing durations

    2 mai 2018, par Mark Walsh

    I am running the following command to crop an MP4 file

    -i "C:\FFMPEG\Temp\S3\2ad239d1-f4b9-4854-afe4-7e28157893daHighRes.mp4" -q:v 0 -y -ss 00:00:01.000 -to 00:00:29.834 -vf "fade=t=out:st=29.334:d=0.500, scale=iw*min(1080/iw\,720/ih):ih*min(1080/iw\,720/ih),pad=1080:720:(1080-iw)/2:(720-ih)/2" "C:\FFMPEG\Temp\Crops\5ae9806e32ab040978d97013_0.ts"

    As you can see I want to crop a video of exactly 28834 milliseconds long. However the created file when inspecting it via ffprobe is 28873 milliseconds long. Why is this ?

    Everything works until it gets to !%input[%x%]%! in the :inputVarious group.

    Because this is the output I get from that line :

    mediainfo --Output=Video;%Height% !x!  1>\Temp\ffmpegres1.txt

    What I’m trying to do is get the data stored in the input[x] array position and send it to mediainfo as input, so that it can get the video’s resolution, store that into the height[x] array.

    I have no idea what I’m doing wrong. Could someone help me ? Tips on how to make the code less redundant and more elegant are also appreciated.

    Obs. : I tried to recreate this in Python but I’m too much of a bad study and couldn’t get working (although what I was able to do, was done in a less janky way)

  • Support scaling to UHD

    6 mai 2018, par Aurelius Schnitzler

    I am using ffmpeg with

    ffmpeg -i GOPR1373.MP4 -c:v libx264 -vf "pad=width=5848:height=2924:x=1964:y=922:color=black,scale=3840:2160" GOPR1373_w.MP4

    Which yields to Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height and x264 [error]: malloc of size 43688832 failed

    yet

    ffmpeg -i GOPR1373.MP4 -c:v libx264 -vf "pad=width=5848:height=2924:x=1964:y=922:color=black,scale=1920:1080" GOPR1373_w.MP4

    works.

    How to fix this ?

    EDIT : I solved it by freeing up memory.
