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->height,
PIX_FMT_RGBA32,
m_pVideoCodecCtx->width, m_pVideoCodecCtx->height,
m_pVideoCodecCtx->pix_fmt,
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.
