Convert YUV422 to YUV

costelha1 — Wed, 25 May 2005 22:39:41 GMT

Can someone please provide an easy/fast way of converting YUV422 (interlaced, U Y V U V ...) to YUV (interlaced YUV YUV ..., or planar)?

Can I expect to find a function to do this in IPP 5.0?

Thanks

Hi,

do you mean upsampling and re-ordering?

We have functions like

/* ////////////////////////////////////////////////////////////////////////////
// Name: ippiYCbCr422_8u_P3C2R, ippiYCbCr422_8u_C2P3R
//
// Purpose: Converts 422 planar image to 2-channel pixel-order
// image and vice versa.

is it close to what you are looking for?

Regards,

Vladimir

It's close, but I really would like to obtaing something like RGB24 (but with YUV). I now information will be duplicated, but I wanted more "standard" format.

Thanks for the help. IPP 5.0 beta now has a function to perform this operation.
