Hi --<div><br></div><div>Does x264 have any support for detecting that it's running on a Hyperthreaded enabled CPU and to only spawn threads for each real CPU? I've noticed that on our quad core i7s, we've seen a total of 9 threads when doing slice based threading (for low-latency support) when encoding a 720p clip. Since the load on the machine appears to be 50% overall and it doesn't get slower when we turn off HT, it appears those extra threads are unable to get the resources to actually run in parallel with the 4 other threads. </div>
<div><br></div><div>I am using x264 as a library in my own program -- so it may be that I've just missed a configuration option that I should've set.</div><div><br></div><div>Thanks!</div><div>dennis<br>
