Sorry, I have no idea about that. I have never been that far. The only thing I ever heard about v4l2 output, is on ELC 2009 presentation list. You can find at following URL: http://tree.celinuxforum.org/CelfPubWiki/ELC2009Presentations Just look for Matthew Porter's presentation. Or maintainer who is responsible for v4l2 output can help you I guess.(but not me) Cheers, Nate On Thu, Jun 11, 2009 at 7:06 PM, xie<yili.xie@xxxxxxxxx> wrote: > Dear Dongsoo Nathaniel ~~ > > Does the capture interface get the image and the output interface > display the image ~ ? > > Best regards ~ > > -- = DongSoo, Nathaniel Kim Engineer Mobile S/W Platform Lab.
