Comment (by oromit):

 I left the following command running for an hour, using nvidia-drivers

 ./ffmpeg -f lavfi -i "testsrc=size=1920x1080" -pix_fmt yuv420p -c:v
 h264_nvenc -b:v 3000k -maxrate 4000k -bufsize 3000k -f null -y /dev/null

 Using ffmpeg built from 1ad4471526c70d073b19bd551dc4193457d1e610, there
 was no increase in memory usage over the whole time.

 So this is either coming from some other component of ffmpeg you are
 using, or from your nvidia driver.
