we used os is win7.
when input video resolution and output video reolution is different, encode will cause memory leak on i7-7700T,
if input video resolution and output video reolution is same , encode will not cause memory leak on i7-7700T.
there is no problem on other cpu(for example: i7-4770, i7-6700).
we found the function caused memory leak is RunFrameVPPAsync. maybe image scale lead to memory leak?
