Oh, yes. I've tried ttyrec a few years ago but have completely forgotten about it since.

I'm still hoping to get by with some hacks, but you might be right. It's a pity and almost a surprise there's no widely available text-based video codec. Maybe I just need to try my luck on mplayer-related mailing lists. P.S. Please don't post to questions@ and freebsd-questions@ at the same time. It's the same list and you're just sending double mails. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
