`sub_frame.bitstream.size` is a `size_t`. This function intends to calculate a signed penalty value from 2 instances of the variable. Both need to be cast to `int64_t` to avoid the calculation being promoted to unsigned when `size_t` is 64 bits. Fixes a (harmless) unsigned overflow warning: ``` src/mux/anim_encode.c:1341:60: runtime error: unsigned integer overflow: 106 - 108 cannot be represented in type 'size_t' (aka 'unsigned long') ``` Bug: 498967191 Change-Id: I45ce174437e5a9bfa856c4d6665f5a60869078b8
