How about av_malloc_array(s-cols * s-rows, sizeof(VP9Block))? Frame w/h
is 16bit limited, so rows/cols are naturally 13bits limited (since they are
in units of 8 pixels), so the product is 26bit max, so it won't overflow. I
don't even think the product of cols*rows*sizeof can overflow, but I guess
it is stylistically preferrable..
ok
applied with that change
thx
