  • 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.

  • L’agrémenter visuellement

    10 avril 2011

    MediaSPIP est basé sur un système de thèmes et de squelettes. Les squelettes définissent le placement des informations dans la page, définissant un usage spécifique de la plateforme, et les thèmes l’habillage graphique général.
    Chacun peut proposer un nouveau thème graphique ou un squelette et le mettre à disposition de la communauté.

  • regarding h264_qsv encoding speed in ffmpeg

    31 janvier 2021, par TONY

    As we know, now ffmpeg supports intel hardware encoding(h264 qsv).
But it doesn't support "ultra fast", is there any settings to improve the encoding speed ?

    


    m_encoder = avcodec_find_encoder_by_name("h264_qsv");
if(m_encoder == nullptr){
    LOG(ERROR)<<"Find H264 Encoder failed";
    return false;
}
m_ctx = avcodec_alloc_context3(m_encoder);
m_ctx->bit_rate = bitrate_kbps*1024;
m_ctx->width = m_width;
m_ctx->height = m_height;
m_ctx->time_base = { 1, (int)fps };
m_ctx->qmin = 10;
m_ctx->qmax = 35;
m_ctx->gop_size = fps;
m_ctx->max_b_frames = 0;
m_ctx->has_b_frames = false;

m_ctx->codec_id = m_encoder->id;
m_ctx->codec_type = AVMEDIA_TYPE_VIDEO;
m_ctx->pix_fmt = m_h264InputFormat;

AVDictionary *param = nullptr;
av_dict_set(&param, "look_ahead", "0", 0);
av_dict_set(&param, "look_ahead_depth", "8", 0);
av_dict_set(&param, "preset", "veryfast", 0);
av_dict_set(&param, "tune", "zerolatency", 0);

int ret = avcodec_open2(m_ctx, m_encoder, &param);


    


  • avfilter/af_afade : improve accuracy and speed of gain computation

    avfilter/af_afade : improve accuracy and speed of gain computation

    Gain computation for various curves was being done in a needlessly
    
inaccurate fashion. Of course these are all subjective curves, but when
    
a curve is advertised to the user, it should be matched as closely as
    
possible within the limitations of libm. In particular, the constants
    
kept here were pretty inaccurate for double precision.
    

    Speed improvements are mainly due to the avoidance of pow, the most
    
notorious of the libm functions in terms of performance. To be fair, it
    
is the GNU libm that is among the worst, but it is not really GNU libm’s fault
    
since others simply yield a higher error as measured in ULP.
    

    "Magic" constants are also accordingly documented, since they take at
    
least a minute of thought for a casual reader.
