Subject: Re: [Mesa-dev] [PATCH 2/2] Added support for NV12 to IYUV conversion
in vlVaGetImage
Hi guys,
Out of curiosity - do you know off-hand about any users of IYUV/I420 ?
I was under the impression that everyone is doing nv12/nv21/yv12 in 99% of the
cases.

I was just about to mention that we're not flipping the planes pointers (and
their respective info) only to see that we're checking vs VA_FOURCC a few lines
below :-)
Perhaps we should add a couple of trivial helpers u_copy_nv12_to_iyuv and
u_copy_iyuv_to_nv12, which wrap around their yv12 brethren ? This way one can
use them directly - be that here, in vdpau and/or elsewhere.
Cheers,
Emil
