%td is completely standard, so %zd cannot be any "more standard". The
result of pointer subtraction has type ptrdiff_t so %td is the most
correct one to use here. If some platform fails to handle such standard
printf features correctly isn't that a libc bug, not a compiler one
(unless the compiler inlines printf calls - and that can't really happen
here because of the indirection through av_log)?
