Hello Everyone! Thank u so much for replying. 1.I meant the chips and technnologies 69030.
2.When I say a "frame rate of 30fps is required",that means I want to play the MPEG4 software decoded movies at the rate of 30fps and at present Iam getting RGB(24 bpp) as the input.I should be able to display on screen 30fps. My question was can I get this rate with the help of BitBLT alone(which has a limitation of 64K)or I don't have any other alternative other than programming the multimedia engine which takes YUV or 16bit RGB as input. Please write if more clarification is needed from my side. I again very much thankful to the gentlemen who replied so fast to the mail. Waiting to hear from u , Regards, Nitin Mahajan mail:[EMAIL PROTECTED] Ph:51101667.

This is already supported in 4.3, including video playback. Capture isn't supported as I never had anything to test it with. I would have replied to the original email if I had been able to understand it better. Egbert.
