Comment (by Benjamín de la Fuente Ranea):

 This is working for me in Windows x64. In the function
 av_image_check_size2, just use this:

 {{{
 #if defined(_WIN64)
     #define MAX_MEM_SIZE INT64_MAX
 #else
     #define MAX_MEM_SIZE INT_MAX
 #endif
     if ((int)w<=0 || (int)h<=0 || stride >= INT_MAX ||
 stride*(uint64_t)(h+128) >= MAX_MEM_SIZE) {
         av_log(&imgutils, AV_LOG_ERROR, "Picture size %ux%u is invalid\n",
 w, h);
         return AVERROR(EINVAL);
     }
 }}}
