  • 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")

  • 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.

  • 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 ?
