  • 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" (...)

  • Acceptable Video Size For Social Network With FFMpeg

    2 août 2022, par John Santos

    I'm building a social network on Android and using FFMPeg to compress the videos before uploading them. Videos will have maximum 1 minute of duration.

    



    The original video for test has 87.74Mb 1080x1920.

    



    Trying to find the middle point between quality and file size I could get to a video size of either 26Mb with an "meh" quality (which I'm not happy with) or 33.06Mb with a good quality (scaling the video to 480x852).

    



    Problems :

    



    1) It's taking an average of 2min 30sec to compress a 1 minute video !

    



    2) Even 25Mb seems to be too much for a 1 minute video for a social network

    



    The ask :

    



    1) Any clue how do Instagram and Facebook do it to compress and upload the same video above within 1 minute !!?? I know they compress it cause the quality is not the same when on Facebook/Instagram but how to they get it done that fast ?

    



    2) What would it be an acceptable file size for a 1 minute video on Facebook/Instagram ? I'm worried about wasting too much storage for 1 minute videos. Does anyone have any idea about it ?

    



    



    I'm searching a lot about FFMpeg commands to get it better and better but it would be easier if I had in mind what I want to achieve.

    


  • Convert file with any extension to MP4 with ffmpeg

    15 novembre 2019, par not legit

    I am using youtube-dl and ffmpeg to create a youtube downloader and converter (for personal use). I am trying to download a video and convert it to MP4.

    The problem I have, is that youtube-dl downloads the video in a variety of formats. Is there a way that I can download the video and then tell FFMPEG to convert it, not knowing the current file type ?

    I tried using a * wild card but that results in an error.

    @echo off
    
title youtube downloader
    

    
set /p name= URL: 
    
echo Select a type. (vid/mp3/mp4)
    
set /p type=
    

    
IF /i "%type%"=="vid" goto vid
    
IF /i "%type%"=="mp3" goto mp3
    
IF /i "%type%"=="mp4" goto mp4
    

    
:vid
    
youtube-dl %name%
    
goto commonexit
    

    
:mp3
    
youtube-dl -x --audio-format mp3 %name%
    
goto commonexit
    

    
:mp4
    
youtube-dl -o video %name%
    
ffmpeg -i video.* video.mp4 -hide_banner
    

    
:commonexit
    
pause
