Subject: spatial svc: set window_size to 15
X-Git-Tag: v1.8.0~803^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6b2cc75622770fc9481c216789e0a684d7883e06;p=libvpx

spatial svc: set window_size to 15

Static analysis does not recognize that output_rc_stat guards
the usage of window_size. Clears this warning:
The right operand of '>' is a garbage value
if (frame_cnt > (unsigned int)rc.window_size) {

set_rate_control_stats sets window_size to 15. Zeroing it
just introduces another static analysis warning.
