  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Showing in-video visual progress bar with FFMPEG ?

    20 mai 2024, par Taapo

    As OBS Studio lacks a visual indicator to show how far a video has progressed (and when you need to advance to the next scene), I was wondering if there is a command-line option (or solution) to get FFMPEG to re-encode the video and show a progress bar at the bottom of the video that shows how long the video has been playing so far.

    


    Is there such a feature ?

  • Using FFMPEG in a Visual Studio 2013 ultimate project, linking error LNK2019

    27 mars 2015, par Jokke Ruokolainen

    I’m trying to use FFmpeg library and TIFF lib in my project (I’m making a .dll and/or .exe also). I have searched through the answers provided in here and Google, and linked the /dev/include 64-bit (32-bit VS making 64-bit project) to Additional Include Directories and shared/bin (library files) 64-bit to linker->Additional Library Directories and did the Linker->Additional Depedencies->avformat.lib addition. I also copied the .dll files to my project folder, but I still keep getting the LNK2019. Here’s how I use the libs and the output of the compiler :

    extern "C" {
    

    
#ifndef inline
    
#define inline __inline
    
#endif
    
#ifndef UINT64_C
    
#define UINT64_C uint64_t
    
#define INT64_C int64_t
    
#endif
    

    
#include 
    
#include 
    
#include 
    

    
}
    
#pragma comment(lib, "avformat.lib")
