H264 decoder high CPU usage issue

Hi,

I want to use the H264VideoDecoder of IPP 7.0

I built the example "simple_player.exe" to play a 1920x1080 h.264 video.

I found very high CPU usage with m_iThreads = 0. (about 60~70%), but the frame rate is 30 fps.

If I set m_iThreads = 1, the CPU usage down to 50% but the frame rate down to about 20 fps.

Desktop Machine Configurations are:

1. Windows 7 32bit

1. RAM: 4GB

2. Processor: Intel(R)Core(TM) i7-2620 CPU @2.70GHz

Is there a way to decrease the CPU usage and maintain 30 fps at the same time?

Could you help me to resolve this?

Thanks and Regards

Rock.
