  • Gestion générale des documents

    13 mai 2011, par

    MédiaSPIP ne modifie jamais le document original mis en ligne.
    Pour chaque document mis en ligne il effectue deux opérations successives : la création d’une version supplémentaire qui peut être facilement consultée en ligne tout en laissant l’original téléchargeable dans le cas où le document original ne peut être lu dans un navigateur Internet ; la récupération des métadonnées du document original pour illustrer textuellement le fichier ;

    15 mars 2021, par mandown2308

    I downloaded this : https://www.gyan.dev/ffmpeg/builds/ffmpeg-release-full.7z but the SHA256 which appears when right-clicking at the downloaded folder is not the same as it is shown at the link. Is this a legit file ?

    


  • Making changes on a video before a download [on hold]

    1er février 2016, par Chris Russo

    We have a website with lots of videos (>10,000) and lots of users (>50,000). Each video might be around 1,2 Gbs.

    The goal is to generate a unique video for each one of the members or users of the website making a small variation either on the audio track of the video, or the keyframes on the video itself, using low frequency beeps, or a few random pixels on specific keyframes.

    I understand that this operation can be done using SoX for the audio track, or FFmpeg in the case of the video, manipulating the keyframes.

    Here’s my question, as we have to choose between 2 options at this point :

    In terms of resources : would it be convenient or even possible to generate in real time a clone of the video and make this variations at the moment that the user’s request the download (please considerate the big volume of videos and users).

    Or it would be convenient to face this problem using HDD, pre-generating and storing the already manipulated videos ready to be served ?

    I understand that storing all this data will require a few many Tera’s but I’m not sure about how much RAM and Microprocessing could be demanded to perform this operations in real time, over videos that might be as big as 1Gbs.
