Have you seen the software on my web page that did the same with the meteor and the bt848 ? This was done perhaps some two years ago, before i found the saa5246 data sheets :) I wouldn't be surprised if the bttv people took the idea from my code -- i concede that i am not very good after the proof-of-concept step in packaging stuff and adding nice graphics... Only problem, resampling the data sucks a lot of CPU power... you can do that on your workstation or home machine, but certainly not on a server... cheers luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
