  • 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.

  • YUY2 image ==>>sws_scale ==>>x264_encoder_encode doesn't work in Windows

    8 décembre 2011, par shiju sasi

    I have a multi media app in Windows using x264 built using MSYS-MingW and ffmpeg Windows binaries. This works for most of the cameras which capture data in RGB24 and RGB32 formats in most of the OSes. But when I tested the app on a Windows 7 (64 bit OS) Sony Vaio Laptop which has an integrated webcam capturing in YUY2 format, the x264_enoder_encode crashes. The sws_scale to convert the YUY2 data to YUV420 Planar any way works fine here too and returns proper stride values. Please check the relevant code fragments that I have attached below.

         x264_param_apply_profile(&m_param, "baseline");
    
       m_pEncoder = x264_encoder_open(&m_param);
    
       x264_encoder_parameters(m_pEncoder,&m_param);
    

    
       m_encoderConvertCtx = sws_getContext(g_iWidth, g_iHeight, PIX_FMT_YUYV422, SCALE_WIDTH, SCALE_HEIGHT, PIX_FMT_YUV420P, SWS_BICUBIC, NULL, NULL, NULL);
    

    
       x264_picture_t m_pic_in, m_pic_out;   //X264 picture variables to get the X264 encoded picture out.
    
       x264_picture_init(&m_pic_in);
    
 m_pic_in.i_type = X264_CSP_I420;
    

    
 x264_nal_t*  m_nals;
    

    

    
 srcstride = g_iWidth * 2;  //For YUYV422 Packed
    

    
 AVFrame* pictIn;
    
 AVFrame* pictOut;
    

    
 int iInBytes = avpicture_get_size(PIX_FMT_YUV420P, SCALE_WIDTH, SCALE_HEIGHT); 
    
 uint8_t* outbuffer = (uint8_t*)av_malloc(iInBytes); 
    
 pictOut = avcodec_alloc_frame(); 
    

    
 avpicture_fill((AVPicture*)pictOut, outbuffer, PIX_FMT_YUV420P, SCALE_WIDTH, SCALE_HEIGHT); 
    

    
 sws_scale(m_encoderConvertCtx, &in_buf, &srcstride, 0, g_iHeight, pictOut->data, pictOut->linesize); //Scale from YUYV422 Packed to YUV420 Plane
    

    

    
///Code after Scale begins
    

    
memcpy(m_pic_in.img.plane[0],pictOut->data[0],SCALE_WIDTH * SCALE_HEIGHT);
    
memcpy(m_pic_in.img.plane[1],pictOut->data[1],SCALE_WIDTH * SCALE_HEIGHT/4);
    
memcpy(m_pic_in.img.plane[2],pictOut->data[2],SCALE_WIDTH * SCALE_HEIGHT/4);
    
m_pic_in.img.plane[3] = 0; 
    

    
for(int iPlane = 0; iPlane < 3; iPlane++)
    
{
    
 m_pic_in.img.i_stride[iPlane] = pictOut->linesize[iPlane];
    
}
    
m_pic_in.img.i_stride[3] = 0;
    

    
int frame_size = x264_encoder_encode(m_pEncoder, &m_nals, &i_nals, &m_pic_in, &m_pic_out);

    Please help if possible, as this has been consuming a lot of time at my end. But I am not able to dig in to the library side for debugging. Any experienced hands are requested to assist.
