  • Other interesting software

    13 avril 2011, par

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Configuration spécifique d’Apache

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • FFmpeg framerate parameter

    24 avril 2020, par mentalmushroom

    I am confused by the FFmpeg framerate parameter. As far as I understand the docs and wiki, it sets the number of frames per second for the input (and the output unless -r option is specified). In fact, when I set the framerate to 1, the video is being played pretty much at its normal speed (25-30, but definitely not 1 frame per second as expected). Setting framerate to 2 makes it play around twice as fast (not 2 frames per second).

    



    To give a little bit more details, there is a python script which reads a video sample frame-by-frame as fast as it can and outputs these frames immediately to FFmpeg :

    



    python main.py -i myvideo.mp4 | ffmpeg -v warning -f rawvideo -pixel_format bgr24 -video_size 768x432 -framerate 2 -i - http://0.0.0.0:3004/fac.ffm


    



    What could be the reason for such behavior ?

    


  • How to build FFmpeg executable for commercial use using Windows ?

    18 octobre 2024, par Xel Naga

    I'm developing a commercial software and it requires ffmpeg.exe to run properly.

    



    I'm aware of the FFmpeg legal page (https://www.ffmpeg.org/legal.html) and want to Compile FFmpeg without "—enable-gpl" and without "—enable-nonfree". However the compilation guide (https://trac.ffmpeg.org/wiki/CompilationGuide) seems neglected because some links lead to 404 pages, and some required programs didn't install properly on my PC, crashed in fact.

    



    I tried all the ways to compile but could not succeed. I use Windows 8.1 and I'm not comfortable with minGW, MSYS, MSVC.

    



    How can I compile FFmpeg executable for commercial use, or better, how can I download ffmpeg.exe (compiled for commercial use) without hassle ?

    


  • Should I open source my source code when I rebuild ffmpeg and dynamiclly link to my program ? [closed]

    20 septembre 2024, par openjz

    I have a c++ program developed on visual studio 2022, and my program need to work with ffmpeg, I rebuild it and I don't know if there is open source problem.

    


    I rebuild ffmpeg for windows msvc paltform (according to https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC) by customize the build configuration, but I don't modify the source code and build script of ffmpeg, and I don't enable gpl or gpl v3 in the build configuration, ffmpeg is dynamiclly linked to my program, I'm sure that the only license I should concern is the LGPL-2.1 or later, in this case, if I want to distribute my program for commercial use, should I open source my source code ?
