  • Taille des images et des logos définissables

    9 février 2011, par

    Dans beaucoup d’endroits du site, logos et images sont redimensionnées pour correspondre aux emplacements définis par les thèmes. L’ensemble des ces tailles pouvant changer d’un thème à un autre peuvent être définies directement dans le thème et éviter ainsi à l’utilisateur de devoir les configurer manuellement après avoir changé l’apparence de son site.
    Ces tailles d’images sont également disponibles dans la configuration spécifique de MediaSPIP Core. La taille maximale du logo du site en pixels, on permet (...)

    This should exercise the corner cases of numerous codecs.

  • FFMPEG : sws_scale does not produce any data in target frame

    7 juin 2019, par Vladimir Glushkov

    I use FFMPEG to decode H264 stream. After I get decoded YUV420 frames I want to convert them into RGB24.

    struct SwsContext * ctx = NULL;
    

    
// frame is AVFrame in YUV420 obtained from decoder. It has all three strides and seem to be valid.
    

    
if (ctx == NULL)
    
                {
    
                    ctx = sws_getContext(frame->width, frame->height, frame->format, frame->width, frame->height,
    
                        AV_PIX_FMT_RGB24, SWS_BICUBIC, 0, 0, 0);
    
                }
    

    
            AVFrame* frame2 = av_frame_alloc();
    

    
            int num_bytes = av_image_get_buffer_size(AV_PIX_FMT_RGB24, frame->width, frame->height, 32);
    

    
            uint8_t* frame2_buffer = (uint8_t *)av_malloc(num_bytes * sizeof(uint8_t));
    

    
            int size = av_image_fill_arrays(frame2->data, frame2->linesize, frame2_buffer, AV_PIX_FMT_RGB24, frame->width, frame->height, 32);
    

    
            int height_of_output = sws_scale(ctx, frame->data, frame->linesize, 0, frame->height, frame2->data, frame2->linesize);
    

    
            callbackFullRGB(state, frameIndex, 0, frame2->data[0], num_bytes, (__int32)frame2->format, (__int32)frame2->width, (__int32)frame2->height);
    

    
            av_frame_free(&amp;frame2);

    However frame2 has no resolution set, pixel format is -1 and data buffer is empty. I have 1280x720 input, stride length is set to 3840 for output frame which is correct. sws_scale also returns 720 as a result - no errors, no exceptions.

    What might be wrong ?
