  • 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.

  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • Opus Audio Codec in Linphone Android 2013 Version

    2 septembre 2015, par Redturbo

    I want to just enabled Opus Audio Codec in my VOIP application, I have try code from here : http://stackoverflow.com/questions/31635522/force-using-just-opus-codec-in-linphone-android/31652551#31652551

    I try to check findpayloadtype first :

    for (PayloadType pt : mLc.getAudioCodecs()) {
    
                pt = mLc.findPayloadType("PCMA", 8000, 1);
    
                Log.d("LinphoneManager", "PayloadType PCMA : " + pt);
    
            }
    

    
            for (PayloadType pt : mLc.getAudioCodecs()) {
    
                pt = mLc.findPayloadType("PCMU", 8000, 1);
    
                Log.d("LinphoneManager","PayloadType PCMU : "+pt);
    
            }
    

    
            for (PayloadType pt : mLc.getAudioCodecs()) {
    
                pt = mLc.findPayloadType("OPUS", 8000, 1);
    
                Log.d("LinphoneManager","PayloadType P : "+pt);
    

    
            }

    PCMA and PCMU show value in log :

    [PCMA] clock [8000], bitrate [64000]

    [PCMU] clock [8000], bitrate [64000]

    but OPUS show null value :

    null

    is that something wrong with my code to got OPUS audio codec, or something else ?

  • configure : Allow log2 with MSVC 2013 onwards.

    11 mai 2014, par Matt Oliver
    configure : Allow log2 with MSVC 2013 onwards.

    Only MSVC 2010 in x64 mode, in the static msvcrt, had a
    
stray log2 function (which wasn’t available in the headers).
    

    MSVC 2013 has got a proper log2 function though.

  • 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")
