Hi, I was amazed that this worked as well as it did! With a combination of a slightly modified nuppelvideo port, a buffering script and mencoder it is possible to capture and compress to AVI from a bktr tuner at full PAL resolution (768x576) *with make buildworld running* on an AMD2000+ - and probably on much less powerful hardware, certainly if you don't run make buildworld while recording :) The test run dropped a few frames, which it seems can be avoided if the make buildworld is run under nice :) The bits to make it happen can be found on ftp.sohara.org in /pub: nuppelvideo.1.1-1.2.patch Patch for nuppelvideo port to enable using stdout. nuppelvideo.tar.gz Version of the Nuppelvideo port with this patch applied. CDRW/bigbuf.pl Big buffer pipe - uses files in /tmp. test.avi Sample 768x576 avi file recorded with make buildworld running! Using this command line: nuvrec -W 768 -H 576 -f 792 -t 1 - | bigbuf.pl | \ nice mencoder -oac mp3lame -lameopts br=128 -ovc lavc \ -lavcopts vcodec=mpeg4:vbitrate=2400:vhq - -o test.avi -- C:>WIN | Directable Mirrors The computer obeys and wins. |A Better Way To Focus The Sun You lose and Bill collects. | licenses available - see: | http://www.sohara.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
