</div></div>What x264 settings are you using? If you're using overly slow<br>
settings, try using faster ones. rc-lookahead in particular tends to<br>
use quite a lot of memory.<br>
<br>
However, it's a bit odd that you're getting 3GB memory usage with SD<br>
resolution, are you certain that it's allocated by libx264?<br>
