hi...

I decode the same h264 source from ip camera.
VLC ( http://www.videolan.org/vlc/)cpu cost : 25%
IPP cpu cost : 50%

How to advance performance for ipp?

CPU: Core 2 Duo
OS: Window XP
Tools : Visual Studio 2003



Best Regards,
Bill

Hi,

is that possible to measure average time (o number of cpu clocks) required to decode frame with VLC? I would think IPP H.264 decoder is able to decode frame faster ata cost of higher cpu usage, for example it may use multi-threading. So, performance is about how fast you can do the same amount of work.

I would also recommend you to take a look at Intel Media SDK (different product) which use hardware acceleration available on platform to minimize power consumption and free up processor for other task.

Regards,
Vladimir
