    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
    Dans un premier temps il active ou désactive des options de SPIP qui ne le (...)

  • Symbol from C file is not being added even though the MakeFile includes its object file

    3 février 2021, par Mahfujur Rahman

    I'm trying to build libavformat with this MAKEFILE. Although the makefile includes avio.o file in its build instruction but it doesn't add any symbol for the functions that are declared on the header file url.h. Source folder which includes the avio.c, avio.h and url.h files can be found HERE.

    


    The nm command for avio.o returns

    


    nm: avio.o: File format not recognized

    


    file command on avio.o shows the following output

    


    avio.o: LLVM IR bitcode


    


    I have checked the nm command on the generated libavformat.so and did not find any symbols for the functions declared on the url.h file

    


    I have been stuck on this for two days. Could not figure out how to solve this problem !

  • Covert a file from mp4 to a file that HTML video tag can display

    I have a mp4 file and I want to display it in HTML. The problem is that it won’t, not only in HTML but also in my player. In VLC I can watch the video but there is no sound. Maybe the file is corrupted ?

    Can I convert this with ffmpeg to a good quality of video and audio ?
