  • 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" (...)

  • 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, (...)

  • Load only the next 10min of HTML video when it is playing - not the entire video

    13 avril 2016, par W3Ape

    I have videos on my website with duration of almost 2h (=> large file size).

    I have managed to convert them to h265 to reduce server load. To further reduce server load I also want the video to only load e.g. the next 10min from the point the user currently is at in the video (and not the entire video). Youtube is doing it this way.

    The HTML preload attribute does not have this option. Is there such a feature in ffmpeg (or anywhere else) ?

    Thanks for a hint

  • How to know the delay of frames between 2 videos, to sync an audio from video 1 to video 2 ?

    8 janvier 2021, par jaimepm

    world.

    


    I have many videos that I want to compare one-to-one to check if they are the same, and get from there the delay of frames, let's say. What I do now is opening both video files with virtualdub and checking manually at the beginning of video 1 that a given frame is at position, i.e., 4325. Then I check video 2 to see the position of the same frame, i.e., 5500. That would make a delay of +1175 frames. Then I check at the end of the video 1 another given frame, position let's say 183038. I check too the video 2 (imagine the position is 184213) and I calculate the difference, again +1175 : eureka, same video !
The frame I chose to compare aren't exactly random, it must be one that I know it is exactly one I can compare to (for example, a scene change, an explosion that appears from one frame to another, a dark frame after a lighten one...) and I always try to check for the first comparison frames within the first 10000 positions and for the second check I take at the end.
What I do next is to convert the audio from video 1 to video 2 calculating the number of ms needed, but I don't need help with that. I'd love to automatize the comparison so I just have to select video 1 and video 2, nothing else, that way I could forget forever virtualdub and save a lot of time.

    


    I'm tagging this post as powershell too because I'm making a script where at the moment I have to introduce the delay between frames (after comparing manually) myself. It would be perfect that I could add this at the beginning of the script.

    


    Thanks !

    


  • Convert video.ts file into video.mp4 using ffmpeg

    11 juillet 2020, par HorizonBloom

    So I tried to convert a file named video.ts into video.mp4 in Python and am getting the error :

    


    FileNotFoundError: [WinError 2] The system cannot find the file specified

    


    Assuming video.ts is already loaded into the program and subprocess already imported.

    


    This is due to the line :

    


    >>> subprocess.run(['ffmpeg', '-i', 'video.ts', 'video.mp4']) but I don't know what's the problem.

    


    I've opened the video.ts file and it seem to be working fine. Python version (3.8.2)
