  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • android nkd no include path in which to search for limits.h #include_next

  • Encoding RGB frames using x264 and AVCodec in C

    6 novembre 2016, par deepwork

    I have RGB24 frames streamed from camera and i want to encode them into h264 ,i found that AVCodec and x264 can do so, the problem is x264 as default accepts YUV420 as input so what i wrote was a program which convert RGB frames to YUV420 .that was by sws_scale function .this works well except that it does not satisfy the required FPS because the converting (RGB->YUV420) takes time.

    This is how i setup my encoder context :

    videoStream->id = 0;
    
vCodecCtx = videoStream->codec;
    

    
vCodecCtx->coder_type       = AVMEDIA_TYPE_VIDEO;
    
vCodecCtx->codec_id         = AV_CODEC_ID_H264;
    
vCodecCtx->bit_rate         = 400000;
    
vCodecCtx->width            = Width;
    
vCodecCtx->height           = Height;
    
vCodecCtx->time_base.den    = FPS;
    
vCodecCtx->time_base.num    = 1;
    
//vCodecCtx->time_base      = (AVRational){1,};
    
vCodecCtx->gop_size         = 12;
    
vCodecCtx->max_b_frames     = 1;
    
vCodecCtx->pix_fmt          = AV_PIX_FMT_YUV420P;
    

    
if(formatCtx->oformat->flags & AVFMT_GLOBALHEADER)
    
    vCodecCtx->flags |= CODEC_FLAG_GLOBAL_HEADER;
    

    
av_opt_set(vCodecCtx->priv_data, "preset", "ultrafast", 0);
    
av_opt_set(vCodecCtx->priv_data, "profile", "baseline", AV_OPT_SEARCH_CHILDREN);
    

    
if (avcodec_open2(vCodecCtx, h264Codec, NULL) < 0){
    
    return 0;
    
}

    when i changes AV_PIX_FMT_YUV420P to AV_PIX_FMT_RGB24 ,avcodec_open2 will fail.
    i read that there is a version of libx264 for RGB called libx264rgb but i even dont know whether i have to rebuild x264 with enabling this option or to download another source or i have to do it programmatically with the first x264 lib.

    the question is how to enable RGB as input to libx264 to use with libavcodec in C .or how to make the encoding or sws_scale more fast .
