  • MediaSPIP Core : La Configuration

    9 November 2010, by

  • Librairies et logiciels spécifiques aux médias

    10 December 2010, by

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
    Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

  • WMA decoding with ffmpeg failed

    24 November 2011, by Ali

    I have problem in decoding WMA/WMAPRO stream with ffmpeg.i have filled extra data from the coming stream.I am able to get bit rate, sample rate, extradata size and other parameters so there is no problem with the codecCtx initilization.

    avcodec_open(codecCtx, codec);

    returns -1

    Anyone help me!

  • FFmpeg. avcodec_find_encoder(AV_CODEC_ID_H264) return false

    14 July 2016, by Иван Чванов

    The problem: I can not connect the h264 codec for encoding and decoding of frames.

    Description:

    I downloaded from here ffmpeg library https://ffmpeg.zeranoe.com/builds/, version dev.

    Connect it to your project QT:

    extern "C"
    
{
    
    #include 
    
    #include 
    
    #include 
    
    #include 
    
    #include 
    
}
    
    
    
#pragma comment (lib, "avcodec.lib")
    
#pragma comment (lib, "avformat.lib")
    
#pragma comment (lib, "swscale.lib")
    
#pragma comment (lib, "avutil.lib")

    Next prescribe av_register_all(); to include all codecs.

    Next, call the function: avcodec_find_encoder(AV_CODEC_ID_H264), returns false.

    In the ReadMe file, the library said that it was collected with —enable-libx264 and —enable-gpl compile the keys including h264 codec that is supposed to be.

    If the call: avcodec_find_encoder(AV_CODEC_ID_MPEG1VIDEO), it returns an object AVCodec, as it should.

    I use the MinGW compiler. OC Windows 7.

    How can I resolve or work around the problem? Compile the library itself has not yet obtained. I understand you to connect sources and "poking" them, that too is meaningless.

    ** Once again, I will describe my problem: **

    I need to encode the codec h264 (can VP9) individual frames in one program, and then decode them in another program. You can use other libraries. The language C ++. It is necessary to use interframe compression codec, rather than simply pressed apart frames.

    Sorry for my english.

    Ideas. Advice. Suggestions.
