Anyone know of a simple conversion routine for this?

Thx in advance

Are you looking to understand and write the routine yourself?

You can find a description of the memory layout of I420 at:
http://www.fourcc.org/yuv.php#IYUV

...for YUY2:
http://www.fourcc.org/yuv.php#YUY2

... and UYVY
http://www.fourcc.org/yuv.php#UYVY

The quick and dirty and thus simple way to do this would be to skip the UV
part of every other YUY2/UYVY macropixel while copying the Y, U and V values
to separate planes on the I420 plane.

I could throw some pseudo code together for you, but if are not looking to
write it yourself I wont bother.

Thanks Mikkel,

Yes I am looking to write the routine myself. I'd like to put it directly
into my existing encoder filter.

thx

Hi all,

This shouldn't be a DirectX SDK issue. However I found there seems to be
available APIs in Intel IPP which implement this kind of conversion. You
may download the Eval version for reference:

Intel Integrated Performance Primitives

Have a great day.

Sincerely,
