  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

    4 février 2011, par

    L’installation de la distribution MediaSPIP se fait en plusieurs étapes : la récupération des fichiers nécessaires. À ce moment là deux méthodes sont possibles : en installant l’archive ZIP contenant l’ensemble de la distribution ; via SVN en récupérant les sources de chaque modules séparément ; la préconfiguration ; l’installation définitive ;

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • How can one concatenate videos with different playback rates using ffmpeg ?

    5 juillet 2015, par ankit

    I had an mp4 (H-264 AAC) video and I changed the playback rates to make 2 new videos at .5x and 2x.

    FFMPEG, "-i", file, filter_complex, output_file_name

    Where (in R),

    filter_complex = paste0("-filter_complex ", "'[0:v]setpts=", vspeed[i], "*PTS[v];[0:a]atempo=", aspeed[i], "[a]'", " -map ", "'[v]'", " -map ", "'[a]' ", " -strict -2")

    When I tried to concatenate them the sped up and slowed down videos using

    `FFMPEG, " -f concat -i ", fname, " -c copy ", fileName, "run", ".mp4"`

    I found that the concatenated video was getting stuck (asynchronous) at the sped up and slowed down parts. How can I concatenate them such that it plays correctly ?

  • how do I save the videos in an specific bitrate using ffmpeg ?

    15 mai 2022, par david

    I am trying to save some videos in specific bitrate (8000k) and for this, I used the following code :

    


    ffmpeg  -i  input_1080p60  -c:v  libx264 -pix_fmt yuv420p  -b:v 8000K -bufsize 8000K -minrate 8000K -maxrate 8000K -x264opts keyint=120:min-keyint=120 -preset veryfast -profile:v high out_1080p.264


    


    but after saving the videos, I find out each video has a different bitrate except 8000k ( for example 5000k, 6000k, 7500k,...). but I define the minrate 8000k. do you know what is the problem and how can I force the above code to have the specific bitrate ? Thank you.

    


  • ffmpeg concatenate videos and then merge with an audio

    6 octobre 2016, par vierzig

    I have a few video files without any audio. I want to concatenate these videos to create a single video and then add a sound track (an mp3 file) to it. Currently I am doing it in two phases -

    First concatenate videos...

    ffmpeg -y -i video1.mp4 -i video2.mp4 -i video3.mp4 -filter_complex "[0:v:0] [1:v:0] [2:v:0] concat=n=3:v=1 [v]" -map "[v]" -c:v libx264 concat_video.mp4

    and then add audio...

    ffmpeg -y -i concat_video.mp4 -i sound_track.mp3 -shortest output.mp4

    This produces fairly good output but it takes considerable amount of time.
    I was wondering if there could be a single ffmpeg command that would do both and save time.
