The i810/i815 can do 720 width YUV input with 2 line buffers. It can do up to 1024 width with 1 line buffer. I have not tested the > 720 width version but the code was committed a few months ago and was working for the author. The Output size is limited only by the resolution of the desktop and available memory bandwidth.
The 720 width version should have better quality than the > 720 width version. -Matt -----Original Message----- From: Dr Andrew C Aitchison [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 31, 2001 3:22 AM To: Paul Robertson Cc: Mark Vojkovich; [EMAIL PROTECTED] Subject: Re: [Xpert]XvShmCreateImage On Wed, 31 Oct 2001, Paul Robertson wrote: > Thanks Mark, > > OK, I'll have to live with that limit and undersample my YUV data as > I copy it into the XvImage. > > If you are right about i810 then that could be a problem for me.

I have watched DVDs on the i815 where both the the window and the pixel size reported on the DVD box were wider than 720 pixels, so this many not be a fatal limit. -- Dr. Andrew C.
