Getting back to the libswscale approach, I was trying to transform the
QImage sequence into AVFrame variables:

        QImage image(path_to_image);
        AVPicture picture;
        avpicture_alloc(&picture, PIX_FMT_RGB32, w, h);
        memcpy(picture.data[0], image.bits(), w*h*4);

        QVector<int> strides(image.height(), image.bytesPerLine());
        struct SwsContext *sws_context = sws_getContext(w, h,
PIX_FMT_RGB32, w, h, AV_PIX_FMT_RGB8, SWS_BICUBIC, NULL, NULL, NULL);
        sws_scale(sws_context, picture.data, picture.linesize, 0, h,
frame->data, frame->linesize);

Is this code something similar or related to your suggestion? Thanks.
