We developing a video conferencing application bases on Intel 3rd generation platform. The application decodes H.264 video received in RTP session by software (not Intel decoder), and then draw the decoded picture on screen using DirectDraw technique while encoding H.264 using Intel H.264 hardware encoder. The picture, that is pushed into encoder, is captured using DirectShow to capture from Video Capture card.
My question here is does DirectDraw drawing affects to H.264 hardware encoder or vice verse. Has any attention in using coplex all these technique?
