When converting a image of format PIX_FMT_YUV410P to PIX_FMT_RGBA32,  
using MMX but not MMX2 the blue rgb component is mixed into the green  
so a blue image gets green.

The context is initialised with

			m_img_convert_ctx = sws_getContext(	m_pVideoCodecCtx->width,  
												m_pVideoCodecCtx->width, m_pVideoCodecCtx->height,
												0, NULL, NULL, NULL);

and the conversion is done with

sws_scale(m_img_convert_ctx, m_pFrame->data, m_pFrame->linesize,0,  
m_pVideoCodecCtx->height, m_pFrameRGB->data, m_pFrameRGB->linesize);

The size of src==dst so its a plain translation of format A to B.
