  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • How to merge multiple videos end-to-end with yt-dlp or ffmpeg [closed]

    12 juillet 2024, par Pengu

    We want to download a bunch of small sections of videos then stitch them all together into one big video. How would we go about this ? Is there a way to bulk-stitch together videos from a particular folder ? We're planning to have thousands of clips, so the more automated it can be, the better.

    


    We are already using yt-dlp and ffmpeg for downloading the sections, so we would prefer if the solution was using those as well.

    


    The closest thing we could find was this https://github.com/yt-dlp/yt-dlp/issues/6595 which, when we try it, runs fine but the resulting clip is the same length as the parts used and doesn't seem to join them together.

    


  • Split videos to chunks using Rails and streamio-ffmpeg

    29 septembre 2021, par Nasser FN

    I've followed this tutorial both parts 1 & 2,https://www.randygirard.com/how-to-create-a-video-upload-platform-using-ruby-on-rails-part-2/

    


    so now I am able to upload videos, convert them to mp4 and display them to the user, but the problem is I want to split the uploaded videos to chunks of 30 seconds each and

    


    return them to the user so he/she can use them for whatsapp status.

    


    This' my main goal !

    


    As I've mentioned earlier, i followed the tutorial above, all I need is how to integrate

    


    and use https://github.com/streamio/streamio-ffmpeg in my rails code for splitting videos

    


    to chunks. Thanks !

    


  • Rotate mp4 videos without re-encoding

    3 novembre 2015, par stedes

    I’m looking for a way to rotate videos shot with my Nexus 4 on my Debian Wheezy sytem. The videos are shot in portrait mode and I would like to rotate them to landscape mode. Preferably the rotation is command-line driven.

    I have found several previous questions which are hinting at a good solution but I can’t seem to manage to get it working.

    To begin with there was this question :
    Rotating videos with FFmpeg

    But it indicates that ffmpeg is outdated and that I should use avconv. I found this question detailing the way to go forward.
    http://askubuntu.com/questions/269429/how-can-i-rotate-video-by-180-degrees-with-avconv

    This made me using following command :

    avconv -i original.mp4 -vf "transpose=1" -codec:v libx264 -preset slow -crf 25 -codec:a copy flipped.mp4

    However, this is painstakingly slow (last test took me more than 6 hours for less than 3 minutes of footage) and does not result in a playable movie. I also get an error in logging output which states Mb Rate > level limit.

    Is there an issue here with the re-encoding ? Should I first re-encode the videos from my phone to another, more "workable" encoding before applying the rotations ? Or am I missing another important point ?

    Thanks in advance
