VLC use only around 0% CPU when watching SD/HD-video? On my mac iStat reports it does? WTF? :D Possible? Confirm? :confused: Hardware accelerated?

Have an MBP 15 2011 2,2 QUAD. Same resultat on both the IGP and GPU.

I meant Activity Monitor as in the below quote:
Also have a look at Activity Monitor (Applications / Utilities /) and select All Processes and sort by CPU to see what the culprit may be.

This is a screenshot of the iStat Pro widget:

Maybe the widget is broken? Have you tried reinstalling it?

Yes, i know. but Activity monitor widget in the corner.

It reports 8-10% (of 800%?) in the activity Monitor

Ah didn't see that. What about the actual Activity Monitor window?
As you have 4 cores with 8 threads, the total load for a movie inside VLC is very low, especially with an SD film. I have a dual core (1 thread per core) C2D CPU with 2.8GHz, and even my VLC Player does not hit more than 40% with a normal 720p .mkv (out of 200% available CPU).

720p test

720p
Cpu usage = (20% / 8 threads ) * 2 (2 threads @ CPU Core) = 5 % CPU USAGE(?).
iStat 0% ACtivity Monitor 2,69 %? I think iStat is to optimistic when it come to CPU usage

Hardware Accelerated?

Sorry but I don't think VLC for Mac OS X has any hardware (GPU) decoding.

Are you sure? In any case I think the cpu usage on VLC are pretty impressive! 720p HD about 5% CPU (0% on iStat, 2,69% on Activity Monitor). If only Adobe Flash would decode HD that good! On stage Video the CPU usage is much much higher and that is with hardware encoding. But that are better the nothing. Youtube unfortunately dont support Flash Stage Video yet.. I think you guys know the rest....

Then again it's a 64-bit app so maybe VLC are using GDC to take advantage of all CPU cores. But i could've sworn they're doing hardware decoding.
