Currently, the card goes automatically in letterbox mode when it receives 16:9, and our software captures the 4:3 frames at size 704x576. What I would like to do is to capture the 16:9 broadcast without letterboxing (and the 4:3 without horizontal padding!) simply by changing the pixel aspect ratio stated in our MPEG files. And since we do 24/7 captures, this has to be done on-the-fly, no reinitialization of the cards or the software allowed. Which leads to 2 questions: 1. How do I sense from the software that the mode is currently 16:9 or 4:3? 2. How do I setup the bttv so that it does variable anamorphosis instead of letterboxing? If that is at all possible of course... I *am* googling for all that, but "16/9" is one of those queries on which search engines are really really bad, like "date" or "thread" :-( TIA, -- Michel Bardiaux R&D Director T +32 [0] 2 790 29 41 F +32 [0] 2 790 29 02 E mailto:mbardiaux@mediaxim.be Mediaxim NV/SA Vorstlaan 191 Boulevard du Souverain Brussel 1160 Bruxelles http://www.mediaxim.com/ -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request@redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list
