convert YUV422 to BGR format

convert YUV422 to BGR format

I know the "ippiYUV422ToRGB" can convert to yuv data to rgb,but the channel order is not compatible with the microsoft "DV Encoder",the first byte of MS DV encoder is Blue,and the last is Red,so I had to use the "ippiSwapChannels" to change the channel order,but the process time of the function is long.Soplease tell me isthere a wayto convertyuv to bgr format directly in IPP?Oranyone can givemesome code to do the same task use SSE/SSE2instruction?
