  • 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" (...)

  • FFMpeg : scale down videos with maximum width and height while maintaining aspect ratio

    20 février 2021, par R3D34THR4Y

    In my program the user can input any video file he wants and have it transcoded ready for social media no matter its dimensions and aspect ratio.
The "export profiles" have many variables but the important ones here are maxheight and maxwidth.

    


    The FFMpeg filters must output a video that follows the following rules :

    


      

    • If the video is vertical, permutate the maxheight and maxwidth values (social media considers both 1280x720 and 720x1280 as "720P")

      • 


    • The video must not have a height superior to maxheight or a width superior to maxwidth.

      • 


    • The original video and exported video have the same aspect ratio and no distortion occurs.

      • 


    • No padding or cropping should occur.

      • 


    • The video should not be scaled if it is already under those maximum dimensions (no upscaling).

      • 


    • The function must work even with odd input resolutions.

      • 


    


    I have tried finding a combination of filters that do that but I haven't been able so far, either the video gets distorted or it gets huge black bars if the aspect ratio isn't right, the solution may be simple but I'm a beginner on this library so I'm probably just missing an easy solution.

    


    My current solution :

    


    ffmpeg -i input.mp4 -vf [in] scale=1280:720:flags=lanczos:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=1 [res]; [res] format=yuv420p [format] -c:v libx264 -c:a aac -movflags +faststart output.mp4

  • Will ffmpeg slow down my server ? [on hold]

    12 novembre 2015, par Akash Bose

    I am trying to build a social network where people can upload their mp3 audio files and I want those files to convert to lower bit rate on the fly with ffmpeg.

    Will it slow down my server if I have minimum amount of good traffic ?

    And it would be great if you can tell what server configuration do i need for this kind of setup ?
