umc_video_enc_con sample on multicore PC

excuse me, i wonder whether the sample program umc_video_enc_con can work on multicore mode while encoding H264 format, since we have a 4-core xeon PC and there is always 1 CPU busy(100%) while running the test.

Both the ipp package and the samples are the newest and the 10.1 version of ICC is used. I compiled the sample codes by typing ./build32.sh and ran it with the param of "-t 4".

Because the umc_h264encoder is written with OPENMP support, we hope it can gain a better performance in multicore PC. However it just didn't work that way :( Any suggestion?

Thanks very much~
