Those tools are merged to /usr/sbin/fwcontrol in both -current and 4-stable. It should work with PAL but I cannot test it. Quoted from fwcontrol(8): EXAMPLES Each DV frame has fixed size and it is easy to edit those frame order. fwcontrol -R original.dv Receive stream. dd if=original.dv of=first.dv bs=120000 count=30 Get first 30 frames(NTSC). dd if=original.dv of=second.dv bs=120000 skip=30 count=30 Get second 30 frames(NTSC). cat second.dv first.dv | fwcontrol -S /dev/stdin Swap first and second 30 frames and send them to DV recorder. For PAL, replace 'bs=120000' with 'bs=144000'. /\ Hidetoshi Shimokawa \/ simokawa@sat.t.u-tokyo.ac.jp PGP public key: http://www.sat.t.u-tokyo.ac.jp/~simokawa/pgp.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-firewire" in the body of the message
