Ah, ok - I did not realize that libdv was going thru an intermediate 422 stage! Hmmm, I wonder if y4mscaler can be used simply to do the 411 -> 420 conversion even in the situation where no scaling is being requested. > Dunno about knowing about it, but I've been testing Matto's patch here > and no harm has befallen any of the mjpeg tools with his mods yet... > will run a few more tests before posting to CVS though. Drop us a line when you've checked in the changes so we know to "cvs update" the smilutils ;) Cheers, Steven Schultz ------------------------------------------------------- This SF.NET email is sponsored by: FREE SSL Guide from Thawte are you planning your Web Server Security?
