Hi Lorenzo Perhaps you forget to make a
int size = avpicture_get_size(avctx->fmt, avctx->width, avctx->height); tempFrame = av_malloc(size*sizeof(uint8_t)); before your avpicture_fill ((AVPicture *)tempFrame,(uint8_t *)img.data,PIX_FMT_BGR24,img.width,img.height) After don't forget to free the tempFrame.
